Re: [Catalyst] Where best to store database connection information?
I have mine in an adaptor class singleton. Just be aware using this approach means if there is an error and you have debug / trace switched on it outputs the username and password in the debug output!

Re: [Catalyst] Catalyst 5.90080 on CPAN!
Well I upgrade the runtime and devel modules via PPM. Noticed I had a few other out-of-date modules that I use so upgraded them also. DBI, Try::Tiny, DBD::ODBC, Data::Dumper, Moose, JSON, HTML::Template, Static::Simple Edited my App.. use Catalyst::Runtime 5.90; Then fired up the devel server for the app without issues and things appear to be working fine. So performed the same updates on the IIS server and it my new app 500 server errored. It seems the required dependency : MooseX::Getopt was not included as a dependency in the Catalyst Runtime update package? Something is screwy with the IIS production server, I try to update the required packages and am getting ERROR: File conflict for 'C:/Perl/html/site/lib/Module/Runtime.html'. The package Module-Runtime has already installed a file that package Alt-Module-Runtime-ButEUMM wants to install. My fears have been realised when trying to update the IIS7 server... never rains and this new app has only been live 3 days as it was launched Friday!

Re: [Catalyst] Random thoughts on helper class generation
I second Octavian's comments. Though I still chose Catalyst over the other Perl frameworks, when you spend copious amounts of time reading docs and learning how to use the Catalyst framework, to then be questioned why you are doing something the way you are in the IIRC because it's wrong or at least outdated and not the best method, when all you are doing is following what the documentation tells you to do, is rather frustrating to say the least, and a waste of everyone's time... which then makes you wonder, how good other framework's documentation is and if that would be easier , simpler and more up-to-date. It's not just the documentation / tutorials and how-to's either, it's even the error messages. Too bad that those people don't have the necessary time for that. That doesn't cover the cryptic, poorly written error / warning messages! There are clearly ridiculously clever people working on this project, but I feel sometimes they need to step back for a second and think... how could I explain this to a total idiot, verbose and verbatim documentation, error messages, tutorial and alike, are not the place for fiendishly clever one liners! Catalyst has a big advantage over the other frameworks other than just being an awesome piece of software and that's the community; it's friendly , accessible and a pleasure to be involved in, it's littered with seriously talented individuals at the top of their game, working in huge corporations with a vast wealth of experience and technical know-how, but the documentation lets this down and it shouldn't.

Hi John, Actually probably missed something in my intended context in the course of the rant. Couldn't agree more with that statement, truly less is more and I wasn't putting a shout out to either change 'Catalyst::Helper' or otherwise bloat things in 'Catalyst Core'. So I think we can agree that it is better to pull things out and delegate to more generic add-in's. I have seen in some reading terms and statements such as monolithic catalyst application ..., which is sadly a sad misnomer and seems more of an indictment on the development model of the authors than an actual problem of Catalyst itself. That said, it doesn't help today much :) Feel free to try a plugin and see what people think. Is a good way to shakeout new ideas. So largely a position on how many people are generally cargo culting the catalyst helper default files, which probably would have been a better title. And otherwise trying to get a feel for what other people were doing as typical, App, Controller, View, Model setups. As for the code, that was my way of saying here's one other way of doing it, what's yours? If anything, the only critique here regarding the helper templates is that new inductees are likely to come on board and just so things as they are in the manual, without much thought to what is actually happening. Hence the reference to getting logging set up under ConfigLoader, and so we show another approach. But not sure exactly what to do about making people think, and think differently, yet. I think a better documentation for Catalyst *written by those who know the internals very well* would be very helpful to solve this problem. Too bad that those people don't have the necessary time for that. I think the fact that Catalyst has too much magic is a reason why most beginners prefer Dancer or Mojolicious.

I'm having a problem with Catalyst randomly deciding when it is OK to have a
controller and a model called the same, as I have in the same root auto
subroutine ,
$c-detach('splashscreen','index').
Where I have both a controller called 'SplashScreen' and a model called
'SplashScreen', and the detach works fine.
However, for another controller / model pair called 'ComplianceUpdates',
This doesn't work
$c-detach('complianceupdates','index').
and errors with...
Couldn't forward to ComplianceUpdates. Does not implement process
Couldn't detach to command complianceupdates: Invalid action or component.
So If I am to use
$c-detach($action);
How do I create a Catalyst::Action object.
What attributes am I meant to be setting in the object before I pass it in, and
where are the docs for this as I can't find them.

RE: [Catalyst] Can't detach from root / create action object
No the documentation isn't clear, if I could understand it I wouldn’t be asking this question. What is $action ? And yes I've looked at the manual. Chapter 3 when you search for 'detach' states.. NOTE: If you use the default template technique, you will not be able to use either the $c-forward or the $c-detach mechanisms (these are discussed in Chapter 2 and Chapter 9 of the Tutorial). So I go back to chapter 2 and search for detach and get zero results the same when I search chapter 9?

Thanks Alexander,
I must have missed this :
$c-detach($c-controller('ComplianceUpdate')-action_for('index'));

$c-detach('complianceupdates','index').

How do I create a Catalyst::Action object.
Exactly like I just told you on IRC:

What attributes am I meant to be setting in the object before I pass it in, and
where are the docs for this as I can't find them.

RE: [Catalyst] Can't detach from root / create action object
Hi Andre,
That is clearer, and Alexander provided me with a working solution, but it
doesn't make sense with your example.
$action is an action object isn't it?
So Alexander's example has :-
$c-detach($c-controller('ComplianceUpdate')-action_for('index'));
So I assume
$c-controller('ComplianceUpdate')-action_for('index');
is returning an action object that is passed to detach.
However, your example just has a string path '/a/my_action_1' , how is that an
action object?
Are you saying detach (for the single argument signature) takes a URL path and
that $action is just a string scalar with a URL path in it and not an action
object reference as I got the impression?
Or are there two single argument signatures to detach() one takes an Action
object and one takes a URL path string?
Because I did a Data::Dumper of
die Dumper($c-controller('ComplianceUpdate')-action_for('index')) and I got
an object!
$VAR1 = bless( {
'namespace' = 'complianceupdates',
'name' = 'index',
'class' = 'HLP_Members::Controller::ComplianceUpdates',
'attributes' = {
'Path' = [
'complianceupdates'
],
'Args' = [
'0'
]
},
'reverse' = 'complianceupdates/index',
'code' = sub { DUMMY }
}, 'Catalyst::Action' );
Having just tested with : -
$c-detach('/complianceupdates/index');
is working.
So the question now is which is better...
$c-controller('ComplianceUpdate')-action_for('index');
or
$c-detach('/complianceupdates/index');
Pass a string or a pass an object?
Thanks,
Craig.

RE: [Catalyst] Can't detach from root / create action object
Awesome, thanks for demystifying this for me!
# go to a string path (/foo/bar/gorch)
# or action object
if (blessed($command) $command-isa('Catalyst::Action')) {
$action = $command;
}
else {
$action = $self-_invoke_as_path( $c, $command, \@args );
}
I'm still at a loss why when I was using the wrong syntax, it was working for
SplashScreen, but the same syntax for ComplianceUpdates wasn't!
And I still can't find where in the docs/tutorial any of this is explained? (a
section and page number would be helpful!)

True.

It's not :) Catalyst magically converts that for you.
See this:
https://metacpan.org/source/JJNAPIORK/Catalyst-Runtime-5.90051/lib/Catalyst/Dispatcher.pm#L148
It either gets an action object, or it translates the path to an object for you.

is working.

I like the string option better. It's cleaner to read. But you should be fine
with both.

RE: [Catalyst] Setting file handle as the response body generates warnings.
I've been using this for while
# check for ok status
if($result-ok)
{
# output header
$c-response-content_type('application/vnd.ms-excel');
$c-response-content_length(length($xls));
$c-response-header(Content_Disposition =
'attachment;filename=NBCS_Export.csv');
# create an IO::File for Catalyst
use IO::File;
my $iof = IO::File-new;
# open XLS
$iof-open(\$xls, r);
# output XLS data
$c-response-body($iof);
# close file
undef $iof;

It resolves the out of memory issue if you try to print direct to
$c-response-body without putting the content in an IO::File object.

We should probably document what it means by $c-response-body can accept a
file handle. Like plack specifies the interface it must deal with. Anyone up
to that?
This FH in body thing is something I've been thinking about a lot lately, in
regards to when Catalyst is running under an event loop for example, should
Catalyst stream the Filehandle a non blocking manner. But it would be great to
document this. Also, I am thinking setting the default size when its missing
could really belong to middleware. Plack has some default middleware that does
this:
https://metacpan.org/source/MIYAGAWA/Plack-1.0030/lib/Plack/Middleware/ContentLength.pm
the means it works looks like this
https://metacpan.org/source/MIYAGAWA/Plack-1.0030/lib/Plack/Util.pm#L68
There's a few things in Catalyst.pm that could profitable just use
Plack::Middleware counterparts.
just a thought.

RE: [Catalyst] More detailed proposal for changes related to content negotiation and REST
Hi John / Alex
Am I missing something here?
In my model I create and return the JSON...
use JSON qw(encode_json);
my %json_hash ;
... add some hash stuff to be made into JSON ...
# return JSON
return encode_json \%json_hash

In my controller I output it to the view / browser
$c-response-body( $c-model('My::Model')-my_method_JSON );
-
With an AJAX call I retrieve the JSON
//
// GET SOME JSON VIA AJAX //
/
var myJSON;
function myAJAXFunction()
{
// call AJAX
makeRequest('/my_controller/my_method_JSON ','',set_JSON);
}
function setJSON(json)
{
// store JSON returned from AJAX call
myJSON = $.parseJSON(json);
}
This is working fine, what shift in paradigm are you trying to create and how
would it affect / alter what I currently do, or indeed make it any easier /
simpler, I can't see it getting much simpler than the few lines of code I
already have, can it?
Or am I doing something wrong?

Hi John,
I thought about it for the last few days and wonder why the, lets call
it rendering, of the data isn't left to the view as defined by the MVC
pattern?
I'd expect that a different view is used depending on the negotiated
content-type.
How do other MVC frameworks choose the view to use?
Should a single action be able to limit the output format or is
controller level granular enough?
Best regards, Alex
Alex,
I think you put your finger on one of the major uneasiness I (and others) have
around the idea of having in the global application model all these registered
formatters. Yes, in theory it feels like we are cheating on the View side of
MVC. I have personally always thought that Catalyst doesn't exactly get it
right the way it is (I think C and V are actually a little too detached for one
thing) and that leads to odd code sometimes. The commonly used
Catalyst::Action::Renderview is a bit too detached for my taste. And what we
call a View tends to mostly just be a View handler (or factory I guess). On
the other hand the basic idea of separation of concerns is sound.
I think the main thing is that this is not intended to replace view, but for
the simple cases where people just want to quickly serialize data (like for all
those ajax endpoints you need to do nowadays, not full on RESTful APIs but
quick and dirty communication between the back and front end. Maybe that's not
a great thing for Catalyst (and honestly I put this out there in the hopes of
provocation some strong reactions.
Personally I prefer to use templates even for creating JSON output, I think you
get cleaner separation that is easier to maintain over time (I really don't
like when I see something like -body (json_encode $sql-run-get_all_rows).
That feels fragile to me. On the other hand I see the attraction of some of
the more lightweight web frameworks where they make it easy to just spew out
JSON.
This is partly why I sketched out an action/controller level alternative, with
the proposed response-body_format thing and the proposed new action subroutine
attributes (just to recap)
sub myaction :Local {
My ($self, $c) = @_;
# ...
# ...
$c-response-format(
'application/json' = sub { json_encode $stuff },
# ...
# ...
);
}
I think this approach feels similar to how some other frameworks operate. Some
offer more sugary syntax for the common stuff, perhaps
$c-response
-json( sub { ... } )
-html ( sub

I have tried within Perl to use decode against the string from the DBI fetch, but it just errors... [error] Caught exception in My_App::Controller:: XLSExport-export Wide character in subroutine entry at C:/Perl/lib/Encode.pm line 176. And that was using UTF-16 and UCS-2 / UCS-2BE encoding types, is seems as per the encode docs Bogus surrogates result in death. And I guess as utf8::is_utf8 comes back as true and the fact it states on the DBD::ODBC docs... Perl scalars which are UTF-8 and are sent through the ODBC API will be converted to UTF-16 and passed to the ODBC wide APIs or signalled as SQL_WCHARs (e.g., in the case of bound columns). Retrieved data which are wide characters are converted from UTF-16 to UTF-8. However, you should realise most ODBC drivers do not support UTF-16 It seems the DBD::ODBC driver is auto converting the data from UTF-16 to UTF-8, and that is where the corruption must be occurring, it even states that UTF-16 isn't really supported under ODBC? So what I have is UTF-8, but after a conversion by the ODBC driver from UCS-2 using UTF-16 encoding, which appears to be making a mess of things. I have checked and I was running DBI v 1.616, so installed latest version 1.627 plus upgraded DBD::ODBC to 1.43 but exactly the same problem! I'm at a loss what else I can do other than throw DBI away and refactor to Win32::ODBC , it seems DBI::DBD::ODBC is converting the data on retrieval into UTF-8 and making a pigs ear of it! I can't see any simple switch or parameter to tell DBD::ODBC to do things differently, can you? There is a whole bunch of Unicode maybe's and caveats on the DBD::ODBC CPAN docs, yet if you scan the Win32::ODBC CPAN docs for a mention of UTF-8 / UTF-16 / UCS-2 or the word Unicode, none of them are mentioned even once, so is that a significant indicator of something? I've checked with DBD::ODBC and Win32::ODBC , that the ODBC.pm is not the same module being used, I can see a flag in the DBI ODBC.pm module of odbc_has_unicode, but it is an read only attribute. Can you suggest anything else that might prevent DBI from corrupting the data on UTF-8 conversion?

RE: [Catalyst] CSV / UTF-8 / Unicode
Thanks Anthony, I will try your suggestions when I'm back in the office tomorrow, I'm on a study day today for my OU course. Would be good to track this down and fix without having to refactor to Win32::ODBC , I eventually want to look at replacing my own DBI wrapper for DBIC ORM but am concerned this wouldn't be possible if I cant get DBI to play ball with MS. Your data is being stored in Unicode data typed columns right? Yes it's NVARCHAR(max) , which I understood is MS's data-typing for uNicode VARiable CHARacters, looking at some sample column data via the Windows SQL Management GUI, it appears to display ok. I know that the data being pasted into it is coming from an MS Access front end application that is linked to the same backend SQL server. I also know that this is a memo / rich text input box control on the form (view) bound directly to the table column via a linked table definition with the backend SQL server and some of what they enter they copy/paste from emails and MS Word documents (and possibly PDF) I can't see any odd characters looking at a small amount of sample data on the SQL server, and the data comes out of Win32::ODBC looking ok too. From what I can tell the data is in Unicode during capture and storage, it's just the retrieval with DBI where it seems to be breaking down. I have to include a longread setting when using DBI::DBD::ODBC with SQL already, otherwise it falls over with the data being to long, so perhaps there is another parameter I need? I really appreciate all the help you guys have given so far, thank you.

I have already done this, I have two SQL wrapper modules one that uses DBI::DBD::ODBC and one that uses Win32::ODBC, I applied it to the same standalone script that produces CSV output, the only difference between the test was one test accessed SQL with the DBI SQL wrapper and one test accessed SQL with the Win32::ODBC SQL wrapper, DBI outputted junk chars, Win32::ODBC didn't. What else should I be doing to test for the culprit of the corruption? You need to see how they are using the ODBC API underneath for handling the data and encoding. Setting the trace flag on DBI (i.e. DBI-trace(n)) will expose the DBD::ODBC activity. I'm not sure of the debugging available for Win32::ODBC. One thing I would check first is what they are treating the column data as. If DBD::ODBC is treating the columns as WCHAR but Win32::ODBC is treating them as CHAR and then doing extra magic decoding (or not), well then you've found a big clue. There has to be different handling or differing levels of ODBC support somewhere. I would assume that DBD::ODBC is doing the right thing, and something else is amiss upstream (but well, never assume with Unicode handling, so make sure with the trace). Also, you are aware that your data will probably be coming back as UCS2 if you're using SQL Server right? No, what is UCS2 and is this handled differently in DBI::DBD::ODBC vs Win32::ODBC ? From what I understand, is ultimately what you've got happening?: Original Input Data - SQL Client - Database Driver - Database (UCS2) - Windows ODBC Driver - DBD::ODBC - Catalyst(?) If so, since you're storing the data as Unicode and the database driver knows this (because your column type is NVARCHAR etc.), conversion to UCS2 happens at the driver stage on Windows. This is lossless between the different Unicodes, so just make sure your input is actual good Unicode up to that point and your data is being stored correctly. Your data is being stored in Unicode data typed columns right? This Email and any attachments contain confidential information and is intended solely for the individual to whom it is addressed.

Hi Alexander,
I have read the DBD::ODBC docs and it seems Unicode is ON by default
Enabling and Disabling Unicode support
On Windows Unicode support is enabled by default
So do I assume the data coming from the DB is Unicode encoded already?
if so , why does decode fall over?
I don't seem able to decode or encode without the app crashing?
Do I have non-Unicode chars perhaps?

No it doesn't, read your DBD's docs.

Ensure that the data coming out from your database is properly decoded, then
make sure it's properly encoded when outputting it.
Never mess with Perls' internal representation of the data by dis-/enabling the

RE: [Catalyst] CSV / UTF-8 / Unicode
Hi Alexander,
Well I think I found the problem... the DBI module!
I went back to my original SQL wrapper for Win32::ODBC in my original
procedural script application before porting to Catalyst (where I moved to DBI).
All my output to XLS in the old script using Win32::ODBC works perfectly, no
funny chars in sight!
So it has to be flaky Windows support in the DBI module to blame wouldn't you
say?
So either I refactor my SQL model wrappers under Catalyst to use Win32::ODBC,
or I find out why DBI is corrupting my SQL data.
No wonder I was going round in circles trying to UTF-8 my data!
DBI on Windows has always been a thorn in my side especially with the long
read issues that occur!
I guess I need to head to the Perl forums for DBI support, though it might be
nice if MST chimed in as I know he's an expert on all things DBI/DBIC.
Is there a switch or flag or something I am missing to make DBI work properly
under DBD::ODBC?
Oh and I did a test with DBI in my old procedural application script and got
the same funny characters as I did with DBI under Catalyst, so I think we can
safely say it is DBI with the problem and not Catalyst.
Any input greatly received.
Regards,
1DMF

So do I assume the data coming from the DB is Unicode encoded already?
if so , why does decode fall over?
I don't seem able to decode or encode without the app crashing?
Do I have non-Unicode chars perhaps?
Craig.
I'd suggest to test it outside of Catalyst with a simple standalone script.
I have neither experience with Perl on Windows nor with ODBC and MSSQL.
Ask on the DBIC list or on IRC, some guys use MSSQL successfully there.

Hi Mike,
The data is coming from MS SQL 2008 R2, I have checked the DB and the column

I am accessing the DB via DBI and have set on the connection string..

MSSQL != MySQL
Though I'm not sure if the utf8 setting has any affect when using an MS ODBC
driver as the flag implies it's for mysql ?
No it doesn't, read your DBD's docs.
I tried to apply my $chars = decode('UTF-8', $xls); and I got an error
saying you cannot decode a string with wide characters.
I don't know what the string is, but when you try to decode you get a wide
character error and when you try to encode you get a wide character error.
If I don't do anything to it and just output it, no error, but the data is
full of junk chars.
Where do I go from here?
Ensure that the data coming out from your database is properly decoded, then
make sure it's properly encoded when outputting it.
Never mess with Perls' internal representation of the data by dis-/enabling
the utf-8 bit.
Thanks,
Craig.

RE: [Catalyst] CSV / UTF-8 / Unicode
All the above seems overkill. I suspect what you want is closer to this:
(but see notes below).
Tried that, didn't work, ended up in a long Catalyst discussion where it was
worked out that I needed to wrap any XLS output to an IO:FILE handle otherwise
Catalyst dies with an out of memory error something to do with streaming data
support issues in Catalyst so the work round is to wrap the output into an
IO:File object.
Second, be aware that $c-response-content_length(length($xls));
Yes, I was doing the encode then using Length (I did read on perldocs about
requesting the length against the octet) , either way, the length was the least
of my worries, keeping Catalyst from falling over with 'Wide Character' errors,
or not getting garbage was my main concern.
And yes, the output is CSV not strictly XLS but I have been told and looked it
up on the net that 'application/vnd.ms-excel' Is the correct MIME header to
pass for CSV that you want MS Excel to open.
Of course, if I have the wrong MIME header for CSV - MS Excel please can you
provide the correct one, as it took me a long time to find that one, as the box
standard 'text/csv' does not work properly when opened in MS Excel.
Though as it appears DBI is corrupting my Unicode data, it might be related to
that rather than CSV-MS Excel per sae!

$c-response-content_type('text/csv');
$c-response-body($xls);
$c-response-header(Content_Disposition =

Then with that content type the plugin would encode $xls as utf8 and add
;charset=utf8 (or whatever it is configured to encode as).
Notes:
First, you are not returning Excel, so the content type is not what you first
listed above, right?
Second, be aware that $c-response-content_length(length($xls)); could be very
wrong. If $xls is really CSV text AND it's decoded then length($xls) is the
length in characters, not octets. Don't set the content length.
Third, Catalyst::Plugin::Unicode::Encoding, IMO, has some issues.
The plugin limits to just these content types.
return $c-next::method(@_)
unless $c-response-content_type =~ /^text|xml$|javascript$/;
Then it does this:
$c-response-body( $c-encoding-encode( $body, $CHECK ) )
if ref(\$body) eq 'SCALAR';
Personally, I think the correct approach is to only encode character data --
that is check to see if the utf8 flag is set before calling encode.
Maybe limit to the content types listed above, but throw an exception for other
content types where the body is a scalar AND has the utf8 flag on. After all,
we can only write out octets or else we get the Wide Character error.

RE: [Catalyst] Out of Memory - File delivery issue
Hi Guys,
Just wanted to update as I have found a resolve.
Initial I wanted to try write direct to the file in the model building the CSV
data, rather than a string scalar, but I just couldn't seem to write to the
open 'string' file handle?
So I went back to my model outputting the CSV data as a string scalar and
returning it to the controller as it was originally ...
Then rather than directly passing the $xls scalar to response-body, where it
was falling over...
I instead wrap it up into an IO::File object and pass that to the
response-body, and it seem to be working fine!
Here is what I now have in my controller that allows me to parse the CSV scalar
string...
--
my ($result,$xls) = $c-model('NBCSXLSExport')-csv_export;
# check for ok status
if($result-ok)
{
# output header
$c-response-content_type('application/vnd.ms-excel');
$c-response-content_length(length($xls));
$c-response-header(Content_Disposition =
'attachment;filename=NBCS_Export.csv');
# create an IO::File for Catalyst
use IO::File;
my $iof = IO::File-new;
$iof-open(\$xls, r);
# output XLS data
$c-response-body($iof);
# close file
undef $iof;
}
else
{
$c-response-body( $result-message );
}
$c-response-status(200);
I would like to thank all those who replied with suggestions and especially
Lukas for his help with this final solution.

Filehandle STDOUT opened only for output at C:/Perl/site/lib/Catalyst/Engine.pm

How do you output content direct to the browser bypassing Catalyst, I can't

Which is exactly what was in my reply and also mentioned in the suggested

So instead of what I currently have...

my ($result,$xls) = $c-model('NBCSXLSExport')-csv_export;
So what you can do in the model is rather than have the method return the
scalars that it currently is, have them output to a supplied filehandle
instead. Either as an argument to instantiating the model or as an argument to
the method called. Whichever suits.
$c-model('NBCSXLSExport', $c-res)-csv_export;
or
$c-model('NBCSXLSExport',)-csv_export( $c-res );
For more on the first approach look at the docs for Catalyst::Model::Factory.
In either case it's your underlying model code that needs the injected
filehandle (or IO::Handle type object to be exact ) to be implemented as the
output source.

However, the browser doesn't get delivered the file, the XLS content is
displayed in the devel console, but nothing is outputted to the browser?
Plus as I have overridden the default 'RenderView' , how do I call it for

mechanism?
All help in understanding how I get this CSV string outputted to the browser

$xls =~ s/[^[:ascii:]]//gi;
# output header

# add to Catalyst response object
$self-res-write($xls);
What's the purpose of MVC in this situation?
I seem to be binding my model to a catalyst object which I was told is wrong in
the IRC and then outputting view headers from my model as well.
Is this the only way to get Catalyst to play with simple data streaming?
I get the feeling I'm doing something wrong here and would appreciate guidance.

RE: [Catalyst] Windows Deployment
Hi Tadhg, I can assure you the wiki IIS / Catalyst page is not out of date as I personally updated it just before Christmas! Were you definitely looking at the following URL? http://wiki.catalystframework.org/wiki/deployment/iis7_fastcgi Please check that URL and let me know what part you are personally experiencing problems with and I will do my best to assist you. I have a fully functioning Catalyst 5.9 set up under ActiveState's Active Perl 5.18 on a Windows Server 2008 R2 using IIS7. I have also installed on a Windows 7 machine for local devel no problems (well ok there were, but I got it sorted!) Regards, Craig. From: Tadhg [mailto:tadhg.da...@gmail.com] Sent: 02 January 2013 12:18 To: catalyst@lists.scsys.co.uk Subject: [Catalyst] Windows Deployment Hi All, I'm trying to deploy a simple Catalyst application for internal users, so I don't need anything fancy load balancing or proxy servers etc. My environment, Server: Windows 2003 server 32 bit Dev Client: Windows 7 64 bit Perl: 5.14.12 32 bit Catalyst: 5.90018 I've had a look at the deployment page on the Catalyst Wiki, which gives a good indication of what sould work (though I think some of it may be out of date). Each option I try leads to a roadblock, so I start down a new path with the same result. My no doubt misguided impressions are, Nginx/Lighttpd have limited win support, Acache is difficult and so not recommended and IIS needs Apache and FastCGI and is therefore doubly complex. What I'd like is somebody to tell me what they have working on windows, or even better what the best/least painful solution is? If appropriate I'll then update/extend the wiki.

[Catalyst] Object / Application Instantiation User Requests
Hi, I'm trying to understand how Catalyst auto instantiates objects in your application such as models. When a worker process is triggered, and the application is loaded, does that one process handle requests for all users of the application. So for example is only one instance of a model instantiated that all users interact with as requests come in or is a new object or even application created for each user (I guess based on sessionid?) I assume the context ($c) object is created for each request, but uses already instantiated model objects? Help understanding when an object is instantiated by Catalyst and it's lifecycle is appreciated. Regards, Craig.

Lets see if we can do better this go around! In order to assist, here's a few thoughts on simple articles you can do: * Take any old article and modernize it... * ...or show an alternative approach. * Elaborate or improve on an idea you've previously written about in a blog, or that you read about in some else's blog. * Cools things you can do now that Catalyst is Plack at the core. * Alternatives to using the stash to pass data around. * Examples of applications not using Template Toolkit or DBIx::Class * Examples of using Catalyst with other frameworks such as Web-Simple and Web-Machine * Examples of testing, especially anything using Behavior Driven techniques (think rspec or cucumber). Alternatively we don't need tech oriented articles. I'd be really happy to see some people write something from a business or planning perspective. For example, if you are a CTO or person in planning, something about how you used Catalyst effectively to rapidly meet business goals would be very helpful. Or if someone wanted to look at the results of the recent poll and perform some interesting analysis, I think the community would love to see that. Lets get it rolling! = What I didn't announce via the blog is that if we don't get enough commitment, it would be better to not do a catalyst only advent article, and just combine our submissions over the one of the general Perl Advent calendars. Having a poor showing in our advent calendar doesn't send the right message and it would be better to have a one or two in a popular and full calendar than a bunch of empty dates on ours.

[Catalyst] Catalyst IIS7 Wiki Instructions
Hi, Don't know if this is the correct usage of the mailing list so I apologise now if it isn't. As a thank you to the Catalyst community for all the help and support I have thus far received and as I promised to T0m as well as to help out MST, I have updated the Catalyst IIS7 Wiki page. http://wiki.catalystframework.org/wiki/deployment/iis7_fastcgi Not only have I replaced all the missing screen shots with new ones but also added additional information, made it more generic rather than 'Strawberry' Perl centric plus added sub categories with further configuration information. This will hopefully help others not struggle, as I did, when first setting up Catalyst on IIS7 Windows 2008 R2 environment and reduce the potential of stupid questions being asked on the mailing list or IRC. Should you find any errors, omissions, inaccuracies or feel it could be improved in some way, please feel free to let me know and I will make any appropriate changes necessary. I hope this helps the Catalyst community as well as others who wish to implement Catalyst over Windows / IIS7. Kind regards, Craig Chant I.T.

The OP says: As per the tutorial I've added the following to the config

So, the OP has done something totally different to what the tutorial says, and
thus it will behave differently.
If he moves that line to inside the View (as the tutorial suggests), it'll work.
If he moves it to inside the 'View::HTML' block in MyApp.pm, thus namespacing
it into the appropriate component, it'll work.
Where it is right now - it will be ignored.

I make a manual change to SQL (switch the 'Locked' flag between 'yes' 'no') , refresh the app and it isn't registering the SQL change, so already it seems something is being cached somewhere and I need to stop this, my apps need to see DB changes instantly.

You're not showing us the debug output of the failing request, so it's very
hard to help debug that request.
If you want this form of interactive help, you'd be much better off dropping
into irc for interactive help, rather than the mailing list, which by it's

Hope to see you in irc!

RE: [Catalyst] Why is $c undefined?
Thanks Ian,
The hierarchy is something that I am finding mind-blowing at the moment,
$self-jqgrid-render($self, , you are calling methods jqgrid-render on
$self, passing in $self, I'm sure it makes sense to you :-)
One thing I would like clarification with if possible.
Where do I put code that requires the use of more than one model?
Do I create a separate model that acts as an interface between the other models?
You see I have two SQL servers in opposite ends of the country and so I have a
model built on Model::DBI that can access one server and another Model that can
access the other, but I have functionality that needs data from both , do some
calculations and output accordingly.
I assume this does not go in the controller, but I create an interface model
with the required methods and functionality that the controller uses?
Regards,
Craig.

I have read and seen frameworks such as Mojolicious encourage a shrinkage of
the Model and move alot of functionality to the Controller, so there is a
paradigm which seems to imply it is ok to do more stuff in the Controller,
but I am leaning towards having the main code in the Model and then bolting
it together via the Controller.
I can understand why you get this impression, I think a lot of people end up
putting code in the Controller when they first start using MVC (I did so myself
in the past).
The Model should be external to your Catalyst app (or whatever framework you
use) so that you can use it in things like cron jobs. It also makes testing
easier if your Model is separate from your Catalyst app. Look at using
something like Catalyst::Model::Adaptor as a thin shell to add your external
Model into Catalyst.
I am moving more and more into making my Controllers as thin as possible. Logic
that I might have previously put into the Controller, I either put into the
Model or I create helper functions. Here is an example of a Controller (from
Mojolicious as it happens but that is not important)
sub user_list {
my ($self) = @_;
$self-jqgrid-render($self, {
rs = $self-schema-resultset('User')-search_rs,
filters = {},
rows= [qw(id name)],
});
}
It's not important to know what is going on here, but this Controller gets a
list of all users, formats the data for use in the jQuery jqGrid allows for
sorting and filtering and outputs the data in JSON format. The point being, the
controller code is kept simple and 'thin'
and yet it does a lot of work behind the scenes.

RE: [Catalyst] Unable to output anything in Root.pm - 'auto'
What was the reason for not using DBIC again?
The non-normalised DB with a missing schema and the fact the data is spread
across two SQL servers on separate DSN's.
I also want my data in a way I can manipulate it, maybe you are all going to
fall down in shock and horror, but I get my records and pass them back as an
array of hashes (recordset), I then play with them , manipulate them, and do
all sorts of stuff with them.
ORM / DBIC doesn't seem to give you this type of access, it wants a DB schema
with relationship mapping to dynamically create all the 1-many / many - many
etc Models and relationships, which won't work with our system, from what I can
tell.
This is my SQL helper class (well two methods as an example)
# Get SQL Routine
sub getSQL {
#_0 = Self
#_1 = Table
#_2 = Columns
#_3 = Where
#_4 = Order By
my ($self,$table,$columns,$where,$order) = @_;
# Build SQL Statement
my $sel = SELECT $columns FROM $table WHERE $where;
# Check for ORDER BY
if(defined $order){$sel .= ORDER BY $order;}
# Connect
my $dbh = $self-dbh;
# set long read because SQL requires it for ODBC
$dbh-{LongReadLen} = 9;
# Run SQL Command
my $sth = $db-prepare($sel) || $self-sql_error(Error in getSQL (Web
Server): $sel);
$sth-execute();
# Declare recordset array
my @rs;
# Loop SQL build recordset
while (my $ref = $sth-fetchrow_hashref()) {
# Build Array of Hashes with SQL Data
$rs[@rs] = \%$ref;
}
# Return record set
@rs;
}
# Count SQL Routine
sub cntSQL {
#_0 = Self
#_1 = Table
#_2 = Where
my ($self,$table,$where) = @_;
#Build SQL Statement
my $sel = SELECT COUNT(1) as COUNT FROM $table WHERE $where;
# Connect
my $dbh = $self-dbh;
# Run SQL Command
my $sth = $dbh-prepare($sel) || $self-sql_error(Error in getSQL (Web
Server): $sel);
$sth-execute();
# Loop SQL Record Set
while (my $ref = $sth-fetchrow_hashref()) {
# Build Array of Hashes with SQL Data
$rs[@rs] = \%$ref;
}
# Return Count
$rs[0]-{'COUNT'};
}
It's just before the return of the record set or count I was wondering if I
need to add '$sth-finish();' or '$dbh-disconnect();' - which I have in my
current (non-catalyst) app version of the class (module).
I also believe that DBIC gets all columns from all tables, which I don't want,
dunno, perhaps I'm missing something with DBIC, but I understand my data the
way I retrieve it and didn't think there was anything wrong with using my SQL
class, it has served me well for 10 years, and powers all my current apps.
How would I use DBIC to get records from two separate DSN's and merge
recordsets?
In my concrete Catalyst::Model I have...
# Check if system locked
if($self-cntSQL('IsLock',Locked='yes')){
$c-response-body('pSorry, system is currently undergoing
maintenance./ppPlease try again later./p' );
return 1;
}
One thing I have found already is the app doesn't seem to see real time SQL
updates even if I issue$sth-finish();$dbh-disconnect(); at the end
of my method.
I make a manual change to SQL (switch the 'Locked' flag between 'yes' 'no') ,
refresh the app and it isn't registering the SQL change, so already it seems
something is being cached somewhere and I need to stop this, my apps need to
see DB changes instantly.
Your advice is appreciated.
Craig.

$sth-finish if you've finished with the results of that statement, ie, you've
looped through the rows and are now done.
$dbh-disconnect if you've finished with the database connection, tho now you
start to think about working in a persistent environment, where you may never
disconnect from the database, and/or have some connection caching setup.
This is where DBIx::Class just takes of all this for you - it does sound like
you're re-inventing a lot here.

Hi Craig,
Writing helpers in your main App.pm and using roles is not either-or.
Roles are one possibility to modify your classes in a reusable way.
If your helpers are really global, which means that they are used by all, or
almost all your controllers, I would put them into your main application class.
If you have more than one application which make use of the same
helpers: Put them into a role:
YourHelperRole.pm:
package YourHelperRole;
use Moose::Role;
has some_attribute = ( ... ); # if you need attributes
sub helpermethod1{
my ($self, $other, $args) = @_;
do_something();
}
sub helpermethod2{
my ($self, $other, $args) = @_;
do_something_different();
}
no Moose::Role; # or use namespace::autoclean or MooseX::MarkAsMethod
1;
App.pm:
use Catalyst qw( ... );
extends Catalyst;
with qw/YourHelperRole/;
...
In my opinion, extending your main App.pm with roles is only useful if you need
the same helpers in different locations, too.
If you only need them for that single application, avoid the overhead related
to using roles.
If you have helpers which are only needed by some controllers, create a role
for your controllers. You can not only implement helpers in you roles, you can
also create method-modifiers, which change the way your methods behave.
Here is an example, which writes sth to the log, after the delete
method was called:
YourLogRole.pm:
package YourLogRole;
use Moose::Role;
requires qw/delete/; #die if the consuming class has no delete
after delete = sub{
my ($self, $c) = @_;
$c-log-debug(DELETE called);
};
no Moose::Role;
1;
Controller1.pm: (has the helpers, but no logging)
package Controller1;
use Moose;
extends Catalyst::Controller;
with qw/
YourHelperRole
/;
sub someaction :Local {
my ($self, $c) =@_;
$self-helpermethod1();
}
...
Controller2.pm: (has helpers AND logging)
package Controller2;
use Moose;
extends Catalyst::Controller;
with qw/
YourLogRole
YourHelperRole
/;
sub delete :Local :Args(1) { ... }
Controller3.pm (has logging, but no helpers)
package Controller3;
use Moose;
extends Catalyst::Controller;
with qw/
YourLogRole
/;
sub delete :Local :Args(1) { ... }
Roles are very powerful tools. I use them a lot.
Read the Moose docs for more information.
If you don't want to learn Moose, roles and so on now, just remember:
1. write sth in a role
2. consume the role in a moose class, using with

RE: [Catalyst] Global 'helper' methods
Thanks Lukas,
I appreciate there is DateTime , though I have so much legacy code that uses my
helper class re-writing everything will be a mammoth task.
I hand rolled a lot when I first started out with Perl, didn't know much about
CPAN or PPM, and couldn't load any modules that weren't part of the core
install on the original 'shared' hosting I was using.
Plus I always felt loading an entire module to re-arrange a tiny string seems a
bit OTT?
Dunno, what's the overhead of DateTime?

You can also define your constants in YourApp/Constants.pl, and use
YourApp::Constants wherever you need them.
YourApp/Constants.pm:
use constant { FOO = 1 };
1;
Controller.pm:
use YourApp::Constants;
# and in some method
...
my $global_foo = FOO;
There might be a better way, but this works...
For handling dates, I recommend DateTime, available on cpan:
Another reason to use DBIC:
DBIx::Class::Inflatecolumn::DateTime automatically transforms dates stored in a
database into a DateTime object, which can be used like this:
my $uk_string = $datetime-dmy('/');
my $us_string = $datetime-ymd('-');
But DateTime is not related to DBIC, DBIC just makes using it easy.
Use it if you have to work with dates a lot. It has lots of methods for
outputting dates, times or both in different formats, and it allows
datetime-math...

Hi Hugh,
I assume this is for Apache and I'm running IIS7, so I guess it isn't
compatible?
It looks like I've been having performance problems because millions of rows
get blessed into objects, not sure of this but it looks like a DBIC thing at
the moment.
That's not good, and is part of the issue of ORM (so I've read), I'm not as
old as you, but I'm still old school, get only the columns and rows you need
when you need them, well that's my take on it and it seems to work for me.

Subject: Re: [Catalyst] Global 'helper' methods
Hi
On measurement in general, I'd recommend: Devel::NYTProf::Apache ; there's a
write up here:
http://www.slideshare.net/bobcatfish/profiling-with-develnytprof
I'm dealing with a largish Catalyst/mod_perl thing at the moment and it's been
tremendously helpful. One tip is that it is very picky about closing the files
that it needs to compile the profiles, I write these into /tmp and then crunch
them with the command line tools.
Incidentally, I am 62 and therefore pretty old-skool and not mad for
ORM-everywhere. It looks like I've been having performance problems because
millions of rows get blessed into objects, not sure of this but it looks like a
DBIC thing at the moment. Currently I've 'cursor'-ed them:
my $cursor = $entries-cursor;
while ( my @row_values = $cursor-next ) {
and that seems to give some improvements in that area...
Best regards Hugh

Hm... how to measure the overhead of a module?
There is a XS version of the module which is used if you have a C
compiler. I don't know the exact overhead, but I know that it is fast.
I have no experience with the pure perl version of that module.
If all you have to do with the dates is the simple string transformation
you are right. As I said before: I recommend to use DT if you are
working with dates a lot. Doing math on dates and times is annoying,
because of leap years, epochs, timezones and so on. If you need this:
Using DateTime is recommended. If not: Its not :)
If you are ONLY using pure perl modules:
You can include all required modules in your distribution. It should run
on any perl installation, even in a shared host environment.
App::FatPacker helps you doing this...
But this doesn't work as soon as you use XS modules.

Thanks Lukas,
I appreciate there is DateTime , though I have so much legacy code that uses
my helper class re-writing everything will be a mammoth task.
I hand rolled a lot when I first started out with Perl, didn't know much
about CPAN or PPM, and couldn't load any modules that weren't part of the
core install on the original 'shared' hosting I was using.
Plus I always felt loading an entire module to re-arrange a tiny string seems
a bit OTT?
Dunno, what's the overhead of DateTime?

You can also define your constants in YourApp/Constants.pl, and use
YourApp::Constants wherever you need them.
YourApp/Constants.pm:
use constant { FOO = 1 };
1;
Controller.pm:
use YourApp::Constants;
# and in some method
...
my $global_foo = FOO;
There might be a better way, but this works...
For handling dates, I recommend DateTime, available on cpan:
Another reason to use DBIC:
DBIx::Class::Inflatecolumn::DateTime automatically transforms dates stored in
a database into a DateTime object, which can be used like this:
my $uk_string = $datetime-dmy('/');
my $us_string = $datetime-ymd('-');
But DateTime is not related to DBIC, DBIC just makes using it easy.
Use it if you have to work with dates a lot. It has lots of methods for
outputting dates, times or both in different formats, and it allows
datetime-math...

RE: [Catalyst] Can't get view / template to work ?
Hi Rob,
As I said, I've tried that also to no avail :-(
I thought the point of setting the template default extension is so you don't
have to provide it?
Shouldn't 'login/login' work?
I can't even get the controller to work?
mydomain:port/login/login just gives me a 404 not found error?
Shouldn't
sub login :Local :Args(0) {
my ( $self, $c) = @_;
$c-stash(template = 'login');
}
Map to mydomain:port/login/login
Why do seem to be going no-where fast with Catalyst?

RE: [Catalyst] I'm loosing the plot here? - Controller behaviour that makes no sense
I had a hunch, so I uploaded the template to 'root' and bingo it found it
so this in MyApp.pm isn't working...
'View::HTML' = {
#Set the location for TT files
INCLUDE_PATH = [
__PACKAGE__-path_to( 'root', 'src' ),
],
}
So does this attribute only work for TT template tool kit?
What's the flag for HTML::Template ? (this is the problem I'm having trying to
follow the tutorial!!!)
Also I now get the following error
Caught exception in Members::View::HTML-process HTML::Template : Attempt to
set nonexistent parameter 'base' - this parameter name doesn't match any
declarations in the template file : (die_on_bad_params = 1) at

package Members::View::HTML;
use strict;
use base 'Catalyst::View::HTML::Template';

TEMPLATE_EXTENSION = '.tp',
render_die = 1,

So how do I set the path for templates when using HTML::Template, why is it

$self-AuthenticateUser($c);

But there is no session ID.
I am still getting the “Use of uninitialized value in concatenation (.) or

I’ve read
http://search.cpan.org/~mramberg/Catalyst-Plugin-Session-0.14/lib/Catalyst/Plugin/Session/Tutorial.pod
Where it states : These plugins will automatically set $c-sessionid at the
begining of the request, and automatically cause $c-sessionid to be saved by
the client at the end of the request.
So why is $c-sessionid uninitialized?
Any ideas where my session info is?

Hi Craig,
Take a look at the default index method in Controller/Root.pm.
If you look at the debug output, you will see that index is called after
auto. Index sets, and therefore overwrites $c-res-body.
If you use a template system, the default end action
(ActionClass:RenderView) will only render the template if $c-res-body is not
set. But setting the body directly, as in index, will overwrite any
previously added content.
Uncomment the line '$c-response-body( $c-welcome_message );' in 'sub index
...', and you will see whatever you write to $c-res-body in auto.
Cheers, Lukas

RE: [Catalyst] Unable to output anything in Root.pm - 'auto'
By the way, what do you need the session-id for? Catalyst handles sessions in
a transparent way
To authenticate users, I don't want to store authentication in the hash and it
seems the only other way to do this is via ORM, which I don't want to use
either.
I find catalyst whenever I look at how it implements anything to do with DB
access, it forces ORM upon you, so I need to write my own authentication code
don't I ?

Subject: Re: [Catalyst] Unable to output anything in Root.pm - 'auto'
Hi again,
about the missing sessionid:
I don't know much about the internals of Catalyst::Plugin::Session, but I guess
that the session is a lazy attribute, and only created if used.
This means: unless you put something in the session, you will not have one, and
therefore have no session-id.
This is very handy, because the overhead related to creating and restoring a
session is only executed if the session is really needed.
If your app has a session-less interface without authentication, and extra
functionality for authenticated users, the session will only be created for
authenticated users.
If you touch your session object before fetching the session-id, it will
work:
$c-session;
$c-res-body(SESSIONID . $c-sessionid);
As soon as you implemented authentication, the session will be used and the
session-id will be set.
By the way, what do you need the session-id for? Catalyst handles sessions in a
transparent way. In most cases, you don't need to access the session-id in your
code. And if it is only for debugging: The session plugin writes the session-id
to $c-log when a session is created or restored. This means: the code showed
above will result in the session-id being printed twice :)

I was under the impression that $c was the context (Catalyst) default variable
and was always passed to every method / subroutine.

the startup time for your application, but unless you
are using plain CGI, this doesn't really matter. (If you use
plain-old-CGI, STOP doing so. Use FastCGI instead.)
3: It sometimes generates more SQL statements than it is required to
fulfill a certain task, but this is only relevant if you are running a
high performance, high traffic site. And IF this is the case, you can
still optimize it.
If you compare it to the benefits I described above, the benefits are
dominant in most cases.
I know that this is not the universal truth (which doesn't exist
anyway). It is my personal opinion. Just think about it.
Additionally: DBIC makes moving from one database system to another very
very easy. You have a SQLite DB, and want to move to Portgresql?
no problem. With DBIC, you are already done :)
Ok. I hope I could help.
Sorry for the DBIC-praising at the end. It is just that I first didn't
want to use DBIC, too. And now I see how much easier my life is with
DBIC, and I think I should have moved to DBIC earlier.

},
},
},
};[/quote]
Have I read the above incorrectly?
I have a non-normalised DB , with an application that functions in a
particular way, I deal with user roles and other such stuff in my own way and
I cannot refactor to use catalyst without ensuring all sections of the system
function the same along with the back end admin system, I can't rewrite both
parts at the same time, this is a live app in production that works
currently, I'm simply trying to learn Catalyst MVC cuteness, not start from
scratch.
From what I can see using any of those authentication modules expects certain
data I don't have or use nor want.
Please correct me if I'm reading the CPAN documentation incorrectly.
I want to refactor my app to be MVC using Catalyst without being forced to do
any other than MVC cuteness and work the way I want to with the a database
that already exists, I got the feeling Catalyst allows this unlike ROR or
other MVC frameworks.
Again, have I got this wrong?
If to use Catalyst I have to have a normalised DB, use specific modules with
data in a particular format, then I will just refactor our systems myself
using my own modules and such, best to find this out now before I spend any
more time on something that isn't suitable.
Thanks,
Craig.

Hey Craig,
I got it. You want to store your credentials in a database, but you don't
want to use DBIx::Class?
What about Catalyst::Authentication::Storage::DBI?
If this doesn't help, you might me right. Maybe you have to write your own
authentication module. In that case, consider making it a
Catalyst::Authentication::Store module, and publish it on cpan. It might be
useful for others, too...
By the way: Catalyst::Model::DBI is a ORM-less, raw DBI model for catalyst.
So ... whenever I look at how it implements anything to do with DB access,
it forces ORM upon you ... is not correct. There are very few things which
are really forced by catalyst. Using DBIx::Class is just considered good
practice. A lot of people use it, thats why it is used in most tutorials and
examples.

Right, that's not the case. It only passes to the :Chained or :Args or
:CaptureArgs methods. This leaves you free to create your own internal methods
that don't get extra $c args interfering with your logic.

RE: [Catalyst] Why is $c undefined?
I'm not sure you'd really want $c-dbh anyway, since that's doesn't
sound like you would be encapsulating the Model very well, and sounds
like you'd have SQL in your controller code?
This was what I thought and am trying to avoid, I am doing my best to keep
concern with SQL trot he Model and any action/method that requires data to use
the Model and have the business logic kept in the Model, so that only
actions-routes and the additional application helper methods are in the
controller.
I have read and seen frameworks such as Mojolicious encourage a shrinkage of
the Model and move alot of functionality to the Controller, so there is a
paradigm which seems to imply it is ok to do more stuff in the Controller, but
I am leaning towards having the main code in the Model and then bolting it
together via the Controller.
So for example the authentication for the user is in the Controller but it
simply utilises the Model
EG.
sub AuthenticateUser {
my ( $self, $c ) = @_;
$c-session;
if(!$c-model('Members')-LogCheck($c)){
$c-forward('/login/login');
}
}
Dunno, this is all new to me and I'm refactoring as I go, so I doubt I'll get
it right first time! Does anyone?

Subject: Re: [Catalyst] Why is $c undefined?
Just a small FYI more than anything, which might help fill in a few gaps...
$c-dbh would need you to modify MyApp.pm, this is useful at times for
creating little helper methods that you want accessible via $c, or to
override existing $c methods.
The session plugin does this too, that's why $c-sessionid is available,
etc. or $c-check_user_roles() when using the Authorization::Roles plugin.
I'm not sure you'd really want $c-dbh anyway, since that's doesn't

There's no black-magic going on, so your AuthenticateUser() sub never
magically gets $c.
In short, you'll only get $c when using the method attributes, such as

This renders the upload progress bar pretty useless with Starman. The progress bar works fine running the app under mod_perl. I suppose using something like Nginx or Perlbal in front of the app would work (because those do cache uploads but also provide a hook for reading upload progress). But, we already have hardware load balancers in front of the app, so don't really need an extra proxy in front of every web server. Any other options? Using a upload/request caching proxy is probably THE correct answer since don't really want to tie up the app with slow uploads.

RE: [Catalyst] Canot get application working on IIS7 via FastCGI
Bingo - You are a genius Tom!
Thank you so, so much, I would never have found that switch buried in the
documentation for a long, long time!
I cannot thank the Catalyst community enough for bearing with me and taking the
time to provide all the suggestions and support I have received!
I was getting very frustrated and disheartened and even popped over to the
Mojolicious mailing list to see what they had to offer, but I must confess, the
reply I got was obnoxious and rude and am so glad I stuck with Catalyst, I
can't stand people who thinks a good reply to anyone's thread is 'Google is
your friend', Google is no-one's friend especially not mine as trawling through
countless threads with contradicting suggestions does not equate to support or
a solution, especially for someone who has a disability and finds reading very
difficult!
I know I've got a long way to go and I'm sure the framework has a lot of
frustration and hurt waiting in the wings for me, but at least I can now start
to develop and see where it takes me.
Oh, I would like to point out for clarity that the '500 Server Error', I
reported yesterday after once more reconfiguring the IIS mapping, was due to a
keying error on my part and nothing to do with the problem I was experiencing.
So apologies if I sent anyone in the wrong direction!
Again, thank you for your support, it really is appreciated.

Craig.

Hey Lyle,
Thanks for the heads up, at least I'm now aware of potential issues for file

As this is standard behaviour for IIS, Catalyst really should be setting this
by default when it's running under IIS. I didn't realise Catalyst had missed
this, otherwise I probably could have answered the op's question from the start.
if ( $ENV{'SERVER_SOFTWARE'} =~ /IIS/ ) {
...
}
IIS also doesn't have the pwd as the folder where the script is running.
So you usually need to do:
use FindBin qw ($RealBin $RealScript);
use lib $FindBin::RealBin;
chdir $RealBin;
Otherwise you get issues when people try to open files with a relative path.

Hi David,
Ah gotcha, thanks found what I believe to be the culprit.
Though I think the code was auto generated when using the helper script to
create the base application?
static = {dirs = ['static', qr/^(images|css)/,]}
Replaced with...
'Plugin::Static::Simple' = {dirs = ['static', qr/^(images|css)/,]}
The warning has now gone when firing up the devel server.

Though while we are on the subject of Catalyst plug-ins, I do get this

[warn] Deprecated 'static' config key used, please use the key
'Plugin::Static::Simple' instead
I've looked at the main application MyApp.pm in the lib folder and the

I've tried putting Plugin::Static::Simple insted but that falls over because
it can't locate the plug-in module, I've checked PPM and I have
'Plugin::Static::Simple' Catalyst CPAN module installed so am little stumped
especially with the limited beginners knowledge I have of your framework so
perhaps you could advise.
Doesnt really matter in this case. It just warns you to use
MyApp-config(
'Plugin::Static::Simple' = {

}
);
instead of
MyApp-config(

RE: [Catalyst] Canot get application working on IIS7 via FastCGI
Hi David, OIC, sorry I thought you were talking about some logs to do with Catalyst other than the standard inetpub W3SVCxxx server logs. Here is what IIS logs show when I access the application.. (IP's have been obfuscated) #Software: Microsoft Internet Information Services 7.5 #Version: 1.0 #Date: 2012-10-18 09:44:38 #Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken 2012-10-18 09:44:38 xxx.xxx.xxx.xxx GET /static/images/catalyst_logo.png - 80 - xxx.xxx.xxx.xxx Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 200 0 0 125 2012-10-18 09:44:38 xxx.xxx.xxx.xxx GET / - 80 - xxx.xxx.xxx.xxx Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 200 0 0 2937 2012-10-18 09:44:38 xxx.xx.xxx.xxx GET /favicon.ico - 80 - xxx.xxx.xxx.xxx Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 200 0 0 46 2012-10-18 09:45:04 xxx.xxx.xxx.xxx GET /librarydocs - 80 - xxx.xxx.xxx.xxx Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 200 0 0 46 The first 3 GET entries are when I visit the root application URL (which displays the Catalyst welcome page) the 4th is the entry when navigating to the path for the LibraryDocs.pm controller. As for the Data::Dumper information you requested, you will need to give me more guidance because I can't get it to output anything? Firstly I cannot find the context variable '$c' , there is a '$ctx' , I assume this is what was meant? I added dump($env); dump($ctx-request-uri); dump($ctx-request-base); After each assignment but nothing was displayed in the browser , nor were there any entries in the IIS logs. I have tried 'print' , in front of those commands, nothing is outputted and nothing appears in the logs. I've also tried 'die' but all I then get in the browser is a 400 error 'Bad Request'. I've even outputted a header first with :- print Content-type: text/html\n\n; Before trying to output the variables, but again all I get is a 'Bad Request' error in my browser. In fact I have now removed all added code by myself, the devel server fires up and I can use localhost:3000 to navigate to my application and it works fine. However, using IE to navigate to the production IIS7 URL, all I get now is 400 Bad Request, so now saying 'nothing works' is an accurate statement? You really need to give me more guidance if I am to provide any of the information you request.

RE: [Catalyst] Canot get application working on IIS7 via FastCGI
Thanks Lyle / Hugh, I've checked the following folders:- c:\inetpub\logs\LogFiles C:\Windows\System32\LogFiles\HTTPERR Plus :- Turn Windows features on or off But there isn't any options for :- Internet Information Services\World Wide Web Services\Health and Diagnostics\HTTP Logging Though It seems logging is on as there are files in HTTPERR folder, but none containing any of the information wanted regarding :- debug or print STDERR Like you suggested Lyle, I created the files myself for output! Usually my perl apps run using :- use CGI::Carp qw/fatalsToBrowser warningsToBrowser/; So I get errors outputted to the browser. Though I would point out that whatever Active State did to the latest perl release for IIS, 'die' no longer outputs a header first so a lot of my scripts now give '500 Internal Server Error' and I'm having to fix them as I go, which is one of the reasons I want to refactor the app to use Catalyst, apart from gaining MVC cuteness and a better architecture I was hoping for better error handling being sent to the browser which it seems 'die' coupled with ' StackTrace' gives, so I'm moving in the right direction. :-) Anyways, I got the required info in the end, so let's hope someone can advise on a solution as to why the path mapping isn't working?

I cannot find any file with the data you seem to think should exist. Where do you believe STDERR goes on Windows IIS7?

[Catalyst] Canot get application working on IIS7 via FastCGI
Hi, I've been going round in circles unable to find any help on why my catalyst application won't work on IIS7 Windows Server 2008 R2 I find all the documentation to be incorrect,, such as setting the path to '*' stops all static content being served from the root/static directory , I had to put '*.' For images etc to show. Now I cannot get any path to be recognised, http://mydomain/mycontroller/mymethod does nothing, and all that will load is the Root.pm - sub index :Path :Args(0) method. It doesn't matter what URL I point my browser to all I ever get is the welcome screen from the Root.pm index method. If I use localhost for the devel server the app resolves the URL path correctly and the associated action runs from the correct controller. However, over IIS7 it will not work and I cannot find any resources to explain why. Please help! Regards, Craig Chant I.T.

RE: [Catalyst] Canot get application working on IIS7 via FastCGI
Hello Tomas, Many thanks for the quick reply, it really is appreciated. I'll try to answer your comments as best I can and sorry if I haven't provided enough information or conveyed myself coherently enough. Patch please? Do you mean there is a patch to address the path issue? '*.' vs '*' Is this for Catalyst, perl, a CPAN module, IIS7? Or do you mean what patch have I installed, if so, none to my knowledge, though I have installed a few CPAN Catalyst:: modules via perl PPM for DBI, Sessions and the dependencies. Though while we are on the subject of Catalyst plug-ins, I do get this message in the devel server output when it's started. [warn] Deprecated 'static' config key used, please use the key 'Plugin::Static::Simple' instead I've looked at the main application MyApp.pm in the lib folder and the plug-ins loaded are :- use Catalyst qw/ -Debug ConfigLoader Static::Simple StackTrace Session Session::Store::FastMmap Session::State::Cookie /; I've tried putting Plugin::Static::Simple insted but that falls over because it can't locate the plug-in module, I've checked PPM and I have 'Plugin::Static::Simple' Catalyst CPAN module installed so am little stumped especially with the limited beginners knowledge I have of your framework so perhaps you could advise. Loading the wrong URI is significantly different to doing nothing, no? Yes sorry if I gave the wrong impression, perhaps I should have worded it differently as I thought I had implied 'other than', maybe this would have been a better statement... Now I cannot get any path to be recognised, http://mydomain/mycontroller/mymethod does nothing, *other than* load the Root.pm - sub index :Path :Args(0) method. Which is what is happening and I hope I've made things clearer as to exactly what I'm experiencing. You haven't given us anything to help try to explain why! Please can you give us the debug output from startup of the app + the debug logs of asking for /, and asking for /a/uri/which/does/not/work ? Also, please add a Data::Dumper::Dumper to the Catalyst::Engine::prepare_path method - one at the start to dump $env, and two near the bottom to dump $c-request-uri and $c-request-base just after they've been assigned to… Sorry again for not providing enough information, I will try to give you what you need but I will need a little help doing that also, can you advise where the logs for the app when running over IIS7- FastCGI are? Is there a file somewhere that gets written to each time the fastcgi.pl script gets executed with this information in it? Also can you guide me to where this change needs to be made 'Catalyst::Engine::prepare_path method ' for Data::Dumper:Dumper, where is the file that needs editing located? , Also is there a Catalyst method to spit out the data via Data::Dumper already integrated into the framework, or do I need to import it myself? I hope you can assist as I've been looking forward to building my next app using your framework. Many thanks, Craig.
