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,

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 { ... } ).

- ... ;
and I guess we could say there's a shortcut to forward to a View instead
$c-response

Is that an actual case you've come across? Ya, that's kind of what I was thinking. Or also having a final fallback parser that tries to figure out the type by other means than just looking at the Content type provided in the request. Or even a '.' final match-anything that does some special logging. It would be easy enough to find out if application/json was in the array more than once by mistake. Seems like a reasonable use case then, although I would encourage future development to aim at putting more specificity in the controller, rather than rely on the global application. The primary reason to have anything here at all is to have a base people can build on. I do fear the globalness of it, but it seems not an unreasonable compromise based on how Catalyst actually works today. We've spoken before about the parsing larger incoming and chunked data thing before. I would love to address this, but right now it seems like something we need better agreement on in the psgi level. For example, since star man already buffers incoming input, it feels silly to me to have catalyst then try to re-stream that. You've already paid the full price of buffering in terms of memory, and performance right? Or am I not understanding? I added a Plack middleware to handle chunked encoded requests -- I needed it for the Catalyst dev server and for Apache/mod_perl. Yes, Starman already de-chunks and buffers and works perfectly. Apache actually de-chunks the request, but doesn't update the Content-Length header and leaves on the Transfer-Encoding: chunked header. So, sadly, I do flush this to a temporary file only to get the content-length to make Catalyst happy. Right, so I think in the end we all agreed it was psgi that should be responsible for dealing with chunks or whatever (based on the http level support of the server). The only think would be could there be some sane approach that exposed the input stream as a non blockable file handle that has not already been read into a buffer (memory or otherwise). I do see the possible advantage there for processing efficiently large POST or PUT. However again this needs to be done at the PSGI level, something like input.stream or similar. That would smooth over chucked versus non chunked and expose a readable stream of the input that has not yet been buffered. I'd really like to have something at the Catalyst level that sanely acheives this end, but I think part of the price we paid when going to PSGi at the core, is that most of the popular plack handlers are pre loading and buffering input, even large request input. This seems to be an area where it might behoove us to work with the psgi group to find something stable. Even the optional psgix.io isn't always going to work out, since some people don't want to support that in the handler (its a somewhat vague definition I guess and makes people uncomfortable). Until them, or until someone helps me understand that my thinking is totally wrong on this score, it seems the best thing to do is to put this out of scope for now. That

the attraction of some of the more lightweight web frameworks where they make
it easy to just spew out JSON.
What I have done in my largest Catalyst app, that feeds data to ExtJS
using Catalyst::Controler::DBIC::API, is a custom DBIC ResultClass that
transforms the values in the HRI-like data structure before it gets
serialized to JSON.
That extra step of transforming data before serializing it belongs imho
into the View, not the controller, because different output formats
might need different transformations e.g. datetime format.
If content negotiation is the feature to add I'd define which View is
responsible for which mime-type. The View class would then become more
than a mere glue for e.g. JSON encoding.
That should be definable per app, overridden by the Controller config
which can be overridden by an action too by e.g. setting a stash or
other config var.
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)

Hi,
Has anybody got some examples about how to use this.
It looks like you just have to put the following lines in the main package
before __PACKAGE__-setup():
use Log::Log4perl::Catalyst;
__PACKAGE__-log(Log::Log4perl::Catalyst-new('/path/to/log4perl.conf'));
That works up to a point in that the log messages are formatted as I want.
However they always go to the STDERR and not to the file given in
log4perl.conf. I've used the conf file in a test, so I know it works outside
Catalyst. I'm using the Catalyst development server, does that over-ride the
logger?
The other thing is that I don't really want to hardcode the filename. It should
be in the application's conf file. However, if I just stick it in there as so:
Log4perl
conf_file
/var/www/mymercedesservice.co.uk/fcgi/catalyst/mbfl2/lib/mbfl2/log4perl.conf
/Log4perl
I can't access it via __PACKAGE__-config-{Log4perl}-{conf_file};
until after setup() has run.

That's how I do it in all of our Catalyst apps:
In My::App:
=item finalize_config
Initializes the logger after the config file merging and loading is done.
=cut
sub finalize_config {
my $class = shift;
$class-next::method(@_);
$class-log(Log::Log4perl::Catalyst-new($class-config-{log}));
}
# Start the application
__PACKAGE__-setup;
around 'prepare' = sub {
my $orig = shift;
my $self = shift;
Log::Log4perl::MDC-remove();
my $c = $self-$orig(@_);
Log::Log4perl::MDC-put( username, $c-user-username )
if $c-user_exists;
return $c;
};
This assumes that the l4p config is in the app config file under 'log' e.g.
from one of my Config::General config files:
log
log4perl.logger WARN, FILE, MAIL
log4perl.appender.FILE
Log::Log4perl::Appender::File

Re: [Catalyst] Out of Memory - File delivery issue
On 2013-05-02 16:04, Lukas Thiemeier wrote: Hi again, FIRST: Your Controller Code looks good. I would use build-in functionality whenever possible. In this case, using $c-res-content_type instead of setting the content type by hand. But your code should work just fine. Your are right. You have to set the headers before using $c-res-print (or write). But this does not mean that you have to do this in the model. You can set the headers in your Controller before running the model code. SECOND: IMO you are right about your concerns regarding the MVC architecture. The Model should provide the data and not deal with HTTP responses. On the other hand, the data has to be provided in some format. XML is a well known standard format for textual data presentation. Providing the data as XML is as good or as bad as providing the data as DBIC objects. (Well, not really. But close enough for this explanation). The cleanest (most MVC conform) way to do this would be to fetch the raw data from your model and create your XML in a special view. There are several ways to do this. You can create XML using a TT view. ( I have done this before, it works fine). Or you can use existing XML views like Catalyst::View::XML::Generator or Catalyst::View::XML::Hash::LX. (I have not used any of them, but the names are promising). I guess there are even more ways to do it... In your Case, you already have a Model which provides the XML Data (which is fine, as I said before). IMO, one of the great things about Catalyst is that it allows you to get the job done quickly. It makes reusing existing code easy. There is no reason to abandon your existing XML-creation code just because it doesn't fit the MVC layout. Doing so would be contra-productive. So, what can be done to re-use your XML Model and still fit into the MVC architecture? I see two ways: The first one would be to update your model that it writes its data to any IO::Handle compatible object. You can pass $c-res to your Model, which is IO::Handle compatible. Your model uses a Catalyst independent API to write out the data. Catalyst streams the data to the client. Your Model Code is still Catalyst independent and does not know that it is writing to a Catalyst::Response object. No tight coupling. You can reuse your model in non-catalyst applications and easily test its functionality using Test::More or any other test suite. ( I think this is more or less the way proposed by Neil) The second way (which I would prefer, since it is even more MVC conform) is the following: Update your Model to return an IO::Handle-style object instead of a string. You can fetch this object from the model in your controller, and pass it to $c-res-body. Catalyst will take care of streaming the data to the client in small chunks. You don't have to pass any Catalyst related objects to the model anymore. Your model returns the data as a well known standard object which happens to be suitable for streaming large amounts data with catalyst. No tight coupling at all. Problem solved. Have a Tea and celebrate. This is my opinion on this topic. I hope it helps you to find a way which fits your needs, and reduces your confusion about Models, Views and controllers in this specific case.

What I was trying to achieve was a catch-all facility for requests other than application defined actions, up to root level (i.e. for user-specified URLs which are then looked up in a database). For the life of me I can't remember why I avoided using the default action to achieve this, probably because I thought being more specific (even just by using a wildcard chain) was the most appropriate way to approach it and more structured. My preference is to keep Controller::Root very bare, but keep a default (i.e. 404) handler in there, and an index type action. I'd suggest adding actions for those errors to the generated root controller when creating new apps. I presume then, that having a /*/... wildcard action to catch everything else is not advisable? Is using the default action the preferred method then to allow for unknown/dynamic URLs where an application defined action is unavailable? The usual thing to do with default is to catch 404 errors. ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/ *** T-Systems Austria GesmbH Rennweg 97-99, 1030 Wien Handelsgericht Wien, FN 79340b *** Notice: This e-mail contains information that is confidential and may be privileged.

[Catalyst] [ANNOUNCE] Catalyst-Runtime 5.90020
The Catalyst team is proud to announce the latest version of Catalyst::Runtime. John Napiorkowski wrote a great blog post [1] about its new features and asks for your comments and suggestions for upcoming features. ! Catalyst::Action now defines 'match_captures' so it is no long considered an optional method. This might break you code if you have made custom action roles/classes where you define 'match_captures'. You must change your code to use a method modifier (such as 'around'). - New match method Method($HTTP_METHOD) where $HTTP_METHOD in (GET, POST, PUT, HEAD, DELETE, OPTION) and shortcuts in controllers called GET, POST PUT, HEAD, DELETE, OPTION). Tests and documentation. Please note if you are currently using Catalyst::ActionRole::MatchRequestMethods there may be compatibility issues. You should remove that actionrole since the built in behavior is compatible on its own. - Initial debug screen now shows HTTP Method Match info - security fixes in the way we handle redirects - Make Catalyst::Engine and Catalyst::Base immutable - Some test and documentation improvements [1] http://jjnapiorkowski.typepad.com/modern-perl/2013/02/catalyst-built-in-support-for-http-method-dispatching-and-whats-next.html -- Cheers, Alex *** T-Systems Austria GesmbH Rennweg 97-99, 1030 Wien Handelsgericht Wien, FN 79340b *** Notice: This e-mail contains information that is confidential and may be privileged.

You have to do a background request mostly known as AJAX. The technical
correct term is XMLHTTPRequest [1].
jQuery has a method for it [2].
If you're using Firefox I recommend installing the Firebug addon which
can be used to easily view the request and response.

I *do* want this in DBIC so that a prefetch specified in some query
doesn't hit the database if the table is cached schema-wide. Any other

would be transparent. I do know DBIx::Class quite well and don't think
that's possible with a component.

Hi,
Got a lot of code in a controller that should be moved out and

stuff from the Model and then emails it.
The script can access the model fine and re-use a
Template::Toolkit template already written fine (I'm using
MIME::Lite::TT). However, in the template itself there's a lot of
calls to the Catalyst context object, in the form of:
[% Catalyst.uri_for( ... ) %]
... which aren't displaying anything. I don't really want to hard
code the URIs, so is there a way to get access to the Catalyst
context object of a running app, in a separate external script?
I can understand the reluctance to hard-code URIs, however i
would be
reluctant to suggest that you bring in the whole of Catalyst just
to
satisfy this one requirement.
What is the template? I presume it is an email, and that you are
putting links to locations within your Catalyst application into the
email?
Correct. It's a bog standard .tt file printing text to be sent as an email,
containing links to actions within the Cat app.
What form of uri_for are you using? If it is just to capture the
applications root then could you replace it with your own
convenience
routine that just implemented that aspect of what uri_for is
doing
without bringing in the whole of Catalyst?
[%
Catalyst.uri_for(Catalyst.controller('MyController').action_for('myaction'),
[ some_id ] ) %]
Could you offer an example, based on my uri_for example above?
I suggest to load your Catalyst app with a config that doesn't load
unnecessary stuff like the models and views, just the controllers and
use $c-uri_for_action.
Take a look at how Catalyst::Test::ctx_request does it or even use
Catalyst::Test...
Thanks,
Anthony

Re: [Catalyst] Two questions about caching
On 2012-10-19 09:57, Hugh Barnard wrote: Hi folks The first question is a little 'simple' but I need to be sure anyway: 1. If I go $c-cache-set(key, $value); is that available to all other users within the catalyst instance or just for that user session? Sorry! As you see the cache is on the $c catalyst app instance so it's the same regardless of other plugins like session. You can create a special key that contains the user id if you need per user caching, but you are responsible for the security of the implementation. 2. FastMmap vs Memcached [something I know 'outside' Catalyst]. It looks as though Memcached has better performance for more complex structures? Any comments or [better] benchmarks welcome, I seem to only have forum anecdotes that suggest this. I'm using FastMmap since years without problems for our company apps but performance isn't critical because they have not much traffic. Are you talking about using it for caching or session storage? If session storage and you have your app balanced over multiple servers you need a common session storage anyways.

Hi Kenneth,
I suppose you mean to use

instead of
[% c.uri_for('/accountdetails/detail/') %][% account.account_id %]
No he doesn't because he isn't using Chained but Local where the
dispatcher knows nothing about the number of args.
I assume that you have defined a relationship on the account_id column
without giving it a different name. This makes DBIx::Class inflate the
related row into an object.
Two solutions:
- use a different accessors for your relationships (that's what I'm doing)
- use acount.get_column('account_id') when you can to get the column
value instead of the related row
Also note that it's a common problem that Template Toolkit calls
everything in list context.
search_rs was added to DBIx::Class to make sure you always get a
resultset object and not a list of row objects.

As already noted you need to specify the prefetch value as arrayref in your

prefetch = [qw( progress compliance department_id metrics )],
FYI: qw() does nothing but saving you to quote every element of the list. It's
equal to
prefetch = ['progress', 'compliance', 'department_id', 'metrics'],
Note that this is all basic Perl and nothing specific of Catalyst or

not sure if this is a problem but you should also collapse your joins,
selects and as' into ArrayRefs, as in
join = [ qw( progress compliance department_id ...)]
actually the last one looks suspicious. the relationships should be
called something like departments, not department_ids. If you have the
same naming for accounts then an account_id is the name (presumably) of
a field in accounts and also a relationship

When I run the page I can see in the sub-queries that it runs that it
has the account_id value as it uses it, but when I try to access it

one of the sub queries using the account_id value:
SELECT me.account_id, me.account_code, me.percent_compliant FROM
HCDB_TEST.COMPLIANCE me WHERE ( me.account_id = ? ): '321'
My template that cretaes the uri:
tda href=[% c.uri_for('/accountdetails/detail/') %][%
account.account_id %][% account.account_code %]/a/td
If someone could point me in the right direction, Ive been fighting
this for days.

{} is a hashref in Perl. You're defining four values for the key
'prefetch', the last one overwrites the three previous ones.
As already noted you need to specify the prefetch value as arrayref in
your case:
prefetch = [qw( progress compliance department_id metrics )],
FYI: qw() does nothing but saving you to quote every element of the
list. It's equal to
prefetch = ['progress', 'compliance', 'department_id', 'metrics'],
Note that this is all basic Perl and nothing specific of Catalyst or
DBIx::Class.

not sure if this is a problem but you should also collapse your joins,
selects and as' into ArrayRefs, as in
join = [ qw( progress compliance department_id ...)]
actually the last one looks suspicious. the relationships should be
called something like departments, not department_ids. If you have the
same naming for accounts then an account_id is the name (presumably) of
a field in accounts and also a relationship

So I would like to use some kind of phrasebook, so that the source code can
use the same, consistent terminology, but the clients see their terminology
in the UI.
I'd prefer not to maintain a separate set of templates for each client,
since that requires keeping changes to templates consistent across sets, and
requires keeping changes to terminology consistent in a set.
So... is there an existing plugin that is used for such things?
Otherwise, I am thinking of writing a plugin that makes use of
Data::Phrasebook (or something similar), allows for configuration of the
phrasebook in the configuration file, and adds a new method to the Catalyst
context variable for querying the phrasebook, e.g. the template may have
something like
h1[% c.phrase('widgets') | html %]/h1
Does this make sense, or is there a better way to do this?

Re: [Catalyst] Running multiple test servers together as the same app
Mount them with Plack? Am 2012-01-26 04:49, schrieb Bill Moseley: A quick questions for the the collective wisdom here. We have an app that is just getting too big and we are splitting it up into separate Catalyst apps (mostly based on feature) to allow groups of developers to work on features independently, develop tests independently and release independently. Hopefully it will be a more scalable approach. So, /foo and /bar might be on different apps, but all under the same domain in production. But, if using the development servers they would be on different ports. In production we can use the load balancer (or the web server) to direct requests to the right app. But, I need suggestions for development. Currently, the developers start up a proxy server that points to their development instances (one or more Catalyst apps). But, that has its own problems (like Apache blocking for some amount of time when a Catalyst dev server is restarted and Apache thinks the server died.) One option I was kicking around was wrapping uri_for to map requests to different paths to different development servers running on different ports. That would simply be per-developer configuration -- meaning each developer has their own port pool to use in the case of developers working on the same dev machine. Any other suggestions how to let developers work with related Catalyst apps (that need to link to each other) using the Catalyst development server?

This has the advantage of knowing the relationship names.

[Catalyst] announcing SQL::Translator::Producer::ExtJS::Model::File
I'm cross-posting this to the DBIx::Class and the Catalyst mailing list as both users might be interested in it. I wanted to do this as soon as I've read the first blog post about the ExtJS 4 data model and last Friday evening I've finally started writing it. After a short discussion on #dbix-class on Friday I chose to implement it as a SQL::Translator Producer so other ORM frameworks could just write a SQL::T::Parser and use it too. Personally I'll use the generated ExtJS classes with Catalyst::Controller::DBIC::API in the backend. The one drawback of making it a sqlt producer is that the dbic parser loses the relationship names when creating the sqlt constraints. This means that for using the resulting ExtJS classes with DBIC::API the user has to change all relationship names. What's your opinion on this issue? Should it be a different module that directly parses dbic resultsources instead of using sqlt?

Re: [Catalyst] In HTML::FormHandler search form (no DB schema) -- how to populate a SELECT field via DBIx::Class?
Why not solve it the exact same way?
Defined a schema attribute an pass your schema when constructing the
form object.
Maybe you only want to pass the country rs instead, whatever fits your
needs best.
Also note that HFH will automatically detect a belongs_to and populate
the Select without a need for the options_country sub!
Come to #formhandler if you have more questions.

Short version: If you have a HTML::FormHandler search form without a
has_field '+item_class' (there's no data-base row corresponding to
its contents) how to you reach your DBIx::Class schemas to populate a
drop-down menu?
Long version: This is in the context of a Catalyst app -- however, I
do know this is either FormHandler question or a DBIC question, and
not intrinsically a Catalyst question, but... hoping the wise folks
here can nudge me in the right direction...
We have several DBIC resultsets including Incident and Country. The
Incident record has this relationship:
__PACKAGE__-belongs_to( 'country' =
'Incident::Schema::DB::Result::Country' );
(And the country schema has_many incidents, of course)
For the CRUD form related to the actual incident table, we have a
matching HTML::FormHandler package with its
has '+item_class'
as expected. This makes it easy to create a
sub options_country {
my $self = shift;
return unless $self-schema;
my $rs = $self-schema-resultset('Country');
#...
}
subroutine for the form, for populating a country drop-down menu in
the HTML.
But!
For the SEARCH form, we are not interested in CRUD, plus we have extra
fields (for example, we want the user to be able to bracket dates with
a start-field and an end-field) so there's no one-to-one correlation
with the database table -- meaning there's no item_class for the
search form. And hence no schema to rely on.
What we're looking for now -- unless there's a better more obvious
paradigm -- is a way to get from an instance of the schema-object,
back to the resultset, for searching.
sub options_country {
my $self = shift; # note $c is not available here :(
# $self-schema will be UNDEF here
my $obj = Spill::Schema::DB::Result::Country-new; # Hard-wired,
yes, is there a better way?
my $rs = $obj-???
# ?
}
I've looked at
- $obj-result_source (Can't call method resolve on an undefined
valued in DBIx/Class/Row)
- $obj-result_source_instance-resultset (Can't call method
default_resultset_attributes on an undef value in
DBIx/Class/ResultSource)
- $obj-result_source_instance-resultset_class-search({},{}) (Can't
use string as a HASH ref in DBIx/Class/ResultSet)
and a couple other dead ends.
It's likely to be something obvious I've overlooked. :( Suggestions?

Perl is case sensitive.
Also you should not have any non Catalyst::Controller subclasses in the

Move you forms to My::App::Form for example.

You should weaken the $c since that code will leak memory without
it. And yes, that's currently the best way to generate urls (that I can
think of anyway), although you can save some typing by using hash slices
instead.

Presumably something goes in here:

);
You can put commonly used macros, formats, etc. in a file named e.g.
pre_process_config.tt in your main templates directory, then add
PRE_PROCESS to your config:
__PACKAGE__-config(
TEMPLATE_EXTENSION = '.tt',
render_die = 1,

PRE_PROCESS = 'pre_process_config.tt'.
);

Hi,
I am curious what everyone thinks as being the best practices for
handling forms in Catalyst. Are there any Catalyst applications you
have run across which are good examples of how to use Catalyst's
features to handle forms?
To illustrate what I am getting at, below is typical Rails (v2)
controller code which implements updating the attributes of an object:
def edit
@book = Book.find(params[:id])
@subjects = Subject.find(:all)
end
def update
@book = Book.find(params[:id])
if @book.update_attributes(params[:book])
flash[:notice] = 'Book successfully updated.'
redirect_to :action = 'show', :id = @book
else
@subjects = Subject.find(:all)
render :action = 'edit'
end
end
In Catalyst, this would be appear something like (and please correct
me if I have made any errors here):
sub edit :Args(1) {
my ($self, $c, $id) = @_;
... set up $c-stash for template 'edit' ...
# no need to set $c-stash-{template} - will be set from the current action
}
sub update :Args(1) {
my ($self, $c, $id) = @_;
...process form...
if (form is valid) {
...perform updates...
$c-flash-{notice} = 'Book successfully updated.';
$c-res-redirect('show', $id);
} else {
... set up $c-stash for 'edit' template ...
$c-stash-{template} = 'edit';
}
}
Any comments on this architecture? Is there a better way? My main problems
are:
1. The code ... set up $c-stash for 'edit' template ... is duplicated
in both edit and update (which is also true for the Rails code).
2. Having the template name defaulted from the current action is nice,
but that means we have to explicitly set it in the update method. Is
it better to always explicitly set the template name in a controller
method? Then update could perform a $c-detach('edit', $id) or would
you use $c-go('edit', $id)?
Thanks,
ER

Am Samstag, den 21.08.2010, 11:51 +0200 schrieb Darren Duncan:
Hello,
For context, I'm currently deploying/demoing a Catalyst app on a client
machine
where it uses a contrived base url scheme to work around a restrictive
firewall
setup. To be specific, the Firewall blocks all ports except port 80 (plus a
few
admin ports like SSH etc) and I want to run through HTTPS, so I've currently
got
the machine's Apache running HTTPS through port 80 rather than 443.
(My development machine isn't contrived at all, so no issue there.)
The contrived url for my Catalyst app looks like this:
https://example.com:80/MyApp/some/page
My app initially works fine here using the FastCGI or CGI server script and
the
urls produced by uri_for() are mostly what is needed here but not quite.
An invocation of:
https://example.com:80/MyApp/some/page
... would have page urls going to the likes of:
https://example.com/MyApp/other/page
... which is correct except for the missing :80, because the result alone
implies port 443 which isn't correct here.
Now from running the first url with ?dump_info=1 shows that the FastCGI/CGI
program, namely Catalyst, *does* receive the necessary information to produce
correct base urls.
Here's a relevant subset of Request details from dump_info:
bless({
base = bless(do{\(my $o = https://example.com/MyApp/;)}, URI::https),
headers = bless({
host = example.com:80,
https = on,
}, HTTP::Headers),
uri = bless(do{\(my $o =
https://example.com/MyApp/some/page?dump_info=1;)}, URI::https),
}, Catalyst::Request)
The base and uri reflect the incorrect output, but the headers records
the
fact that both port 80 was invoked and https is on. Using the latter 2 bits
of
information, Catalyst should be able to construct https://example.com:80;
urls.
Therefore, can anyone tell me how to configure Catalyst so that it builds the
urls I need, or alternately where in the Catalyst source I should look in
order
to create a patch to enable this?
Ideally this added smarts could make it into a CPAN release, if code changes
are
needed, but I would like to have this working quite soon, so if I knew what to
patch in the meantime to get this to work, I would appreciate it.
Undoubtedly, Catalyst should simply handle this situation, but I'm not
surprised
that it doesn't yet, considering this is an edge case that the developers may
not have encountered before.
Thank you. -- Darren Duncan

Re: [Catalyst] How to share a database connection across multiple Catalyst apps?
I guess the DBA's don't like it because Oracle starts one process per connection unless you use connection pooling. I think that's a listener setting, your DBA's should know. -- Best regards, Alex Am Mittwoch, den 08.09.2010, 16:54 +0200 schrieb Simon Miner: Thanks for the responses, Jason, I don't think reducing the number of database connections will hurt responsiveness. Even though there are 3 separate Catalyst apps, each HTTP request will only involve one of them (since they all run out of the same web server), so there should never be contention between the apps for the shared database connection. Does this make sense? Tom and Nicholas, I wish this was premature optimization, but my organization has experienced serious performance issues in the past related to multiple (Oracle) database connections per HTTP server process. Extra Oracle connections are expensive to maintain, particularly on the database server, and so we've tried to ensure that a single server process only has a single connection to a given database (since that's all it should need at any given time). I've attached a Devel::NYTProf screenshot for one of the server processes I profiled this morning. Looks like it confirms the multiple database connections. So back to initial question -- How do I update the models of my three Catalyst apps to share a single Oracle database connection? Thanks again. I really appreciate your feedback.

Re: [Catalyst] Chained actions with can't terminate with :PathPart('') ?
Trevors example might overwhelm you a bit if you're not already that
familiar with chained.
The thing to understand is, every endpoint needs to end with an action
that uses Args, every part in the chain CaptureArgs, both might be (0).
So in your example you need a middle chain part for lot with two
endpoints, one with Args(0) to match just /lot and another one with
Args(1) that captures the lot id and matches /lot/5.

However, I would also expect the below to work; but, it seems it doesn't. I
can only formulate the effect I want the above way. This is
unfortunate because if all chained descendants of `lot` utilize a
check provided here in the chain, then shouldn't `view_lot` also get
to utilize that code? It would certainly be nice to eliminate
redundant code here.
sub lot :Chained('/auth/company') :CaptureArgs(1) {
sub view_lot :Chained('/auth/company/lot') :PathPart('') :Args(0) {
I think it is also confusing to those that first encounter it.
I always know that I could just call it /view, and be done with it, but still.
/auth/company/5/lot/5/view rather than, /auth/company/5/lot/5
But, I just wanted to know what others thought of this.

The specific search functionality should instead be pushed down into
your ResultSet classes, so that you say:
$c-model('DB::Books')-find_all_books_by_author($author_name);
Rather than $c-model('DB::Books')-
search({ %stuff_including_author_name }, { %ordering_stuff });
The former is your controller declaratively asking the domain model
for what it wants. The latter is for controller manipulating the
domain model directly by having knowledge of it's implementation.
Which tables you join (and how you join / sort / order / filter them)
to get a set of data _IS NOT_ something controller code should know or
care about, as that takes away your ability to alter the data
representation (e.g. changing the table structure) without changing
every place that knows about that representation...
When you need to change your schema (and this will happen!), then only
having to change the implementation details in the model is
significantly less work (and testing), especially when you have dozens
of controllers!

Re: [Catalyst] Socket error when launching Catalyst server
This means that another process is already listening on the tcp port the catalyst server wants to use (default 3000). Maybe you have already an instance of the cat webserver running. If you need to run multiple cat apps at the same time specify the port number by using the command line option -p(ort). -- Best regards, Alex Am Montag, den 15.03.2010, 16:32 +0100 schrieb David: Hello, recently I am getting next error message once I have launched Catalyst server: Couldn't create daemon: IO::Socket::INET: Address already in use at /usr/local/share/perl/5.8.8/Catalyst/Engine/HTTP.pm line 211.

Re: [Catalyst] Check session expiry without extending it
My solution is to return an error message which includes the link to the
login form with Catalyst::Controller::DBIC::API.
My ExtJS store class has an exception handler that shows a MessageBox
with the error text:
exception:function(sender, type, action, options, response, arg) {
switch (type) {
case 'remote':
var errortext = 'server error occurred';
if (response.raw.errors.generic) {
errortext = response.raw.errors.generic.join('br /');
}
Ext.Msg.alert('Error', errortext);
break;
case 'response':
if (response.isTimeout) {
Ext.Msg.alert('Error', 'the request timed out');
}
else {
Ext.Msg.alert('Error', response.statusText);
}
break;
// that should never happen according to extjs docs
default:
Ext.Msg.alert('Error', 'unknown error occurred');
break;
}
}

I've been solving that session-has-expired-so-ajax-call-fails problem by
having a global listener on my ajax class that checks whether the
session cookie has expired before every xhr request. I'm not completely
happy with how this works (it feels kludgy; it assumes the cookie
expiration time == session expiration time; and it relies on an alert()
to halt the browser's progress (effectively making an async call
synchronous)), but so far it's the most effective way I've found of
preventing user meltdown when their carefully crafted request will be
lost because the session has expired on the server end.
// make sure we are logged in before every xhr request
Ext.Ajax.on('beforerequest', function(conn, opts) {
if (!AIR.Auth.isAuthenticated()) {

// get session cookie. Returns false if the cookie is expired.

var auth_tkt = Ext.util.Cookies.get('auth_tkt');
return auth_tkt;
}
// spawn a popup window to the login page, halting the browser's
// XHR call with an alert()
AIR.Auth.login = function() {
// open a popup panel
var winOpts =
'height=400,width=400,resizable=yes,scrollbars=yes,menubar=yes';
// the closeWindow param tells the login script to generate

var url = 'https://my.sso.url/login?back=closeWindow';
AIR.Auth.window = window.open(url,'login-window',winOpts);
if (window.focus) {
AIR.Auth.window.focus();

Re: [Catalyst] UTF-8 and mails
Before testing end-to-end figure out if the chars from your database are

If you're using DBIx::Class to access your database see
http://www.perlmonks.org/?node_id=736234.

Hi,
first of all: I have read
http://dev.catalystframework.org/wiki/tutorialsandhowtos/Using_Unicode
(especially the Tips for Troubleshooting Unicode in Perl Web Applications)
Nevertheless I have a strange UTF-8 problem that I need help with:
Concerning UTF-8 everything in my App seems to work correct - except my mail
action (I use Mail::Sender::Easy) in my Root controller:
code
(...)
use Mail::Sender::Easy qw(email);
use utf8;
(...)
sub mail :Private {
(...)
$mail_return = email({
(...)
'subject'= (... something from the database ...),
'_text_info' = {
charset = 'utf-8',
encoding = 'quoted-printable',
},
'_text' = (... some text with literal UTF-8 characters NOT from the
database ...),
(...)
});
(...)
}
/code
This produces mails that have messed up UTF-8 characters although the charset
is set in the mail header, and the clients (right now tested with Thunderbird
3 and Outlook 2003) are configured to treat incoming mails as utf-8 encoded
text. Strange: If I switch to ISO8859-1 in Thunderbird, the mails look
alright. Outlook however simply drops the UTF-8 characters, so that p.ex. the
German sentence Nachricht für Herrn Müller results in Nachricht fr Herrn
Mller.
If I remove the use utf8, the UTF-8 characters that do NOT come from the
database look fine (in the example above: everything in '_text'), the ones
from the database are messed up (in the example above: everything in
'subject'). Removing the charset = 'utf-8' flag of the mail subroutine
results in fine mails if I set the charset to ISO8859-1 in the clients.
To summerize: I have UTF-8-tifized everything that I am aware of - i.e.:
- Editor where the source code is produced
- source code itself
- in the MySQL database every table is set-up with UTF-8 Unicode charset and
utf8_general_ci collation.
- the webbrowsers
- the email clients
- Catalyst (use utf8, UTF8Columns)
- Template Toolkit (View::TT = {ENCODING = 'UTF-8'} )
- FormFu (tt_args = {ENCODING = 'UTF-8'})
Any hints on where the problem might be?
Thanks
Jens

Evening (or insert relevant time zone here).
I'm happy to announce the next release of Catalyst-Runtime (5.80016).
This release mainly fixes regressions introduced with the new script
system. Upgrading to the new scripts requires the latest Catalyst-
Devel package (1.24), and choosing to regenerate your scripts.
This release cures all issues reported with upgraded scripts (or
applications generated with the latest release of Catalyst::Devel) and
fixes Win32 issues introduced with the tests for encoding issues fixed
in 5.80015.
Full changelog included below as always.

5.80016 2009-12-11 23:23:33
Bug fixes:
- Fix slurping a file to work correctly with binary on Win32 in the
encoding test controller.
Bug fixes in the new scripts (for applications which have been
upgraded):
- Allow --restartdirectory as an option for the Server script, for
backwards compatibility. (Dave Rolsky)
- The --host option for the server script defaulted to localhost,
rather
than listening on all interfaces, which was the previous
default. (Dave
Rolsky)
- Restore -p option for pid file in the FastCGI server script.
- Fix the script environment variables MYAPP_PORT and MYAPP_RELOAD
RT#52604
- Fix aliasing applications under non-root paths with mod_rewrite in
some apache versions where %ENV{SCRIPT_NAME} is set to the real
name of
the script, by using $ENV{REDIRECT_URL} which contains the non-
rewritten
URI.
- Fix usage display when myapp_create.pl is run with no arguments.
RT#52630
New features:
- The __MOP__ hash element is suppressed from being dumped fully
(and instead stringified) when dumping the error screen to be
less packed with information of no use.
Documentation:
- Fix Pod nits (RT#52370)

Call your top level path part root, then inherit (or apply as a role)
the rest of the chain parts.
e.g.
package MyApp::Stuff;
use Moose::Role -traits = 'MethodAttributes';
sub thingie : Chained('root') PathPart('thingie') Args(0) {}
package MyApp::Controller::Root;
with 'MyApp::Stuff';
sub root : Chained('/') PathPart('') CaptureArgs(0) {}
package MyApp::Controller::JSON;
with 'MyApp::Stuff';
sub root : Chained('/') PathPart('json') CaptureArgs(0) {}
Will give you:
/thingie
and
/json/thingie

Also look at the RestTest app used for the tests to find possible bugs

The relevant part of the controller is:

use JSON::Syck;
__PACKAGE__-config(
action = { setup = { PathPart = 'artist',

Now for the problem. When I go to test this:
my $mech = Test::WWW::Mechanize::Catalyst-new;
ok(my $schema = DBICTest-init_schema(), 'got schema');
my $req = GET(http://localhost/api/rest/artist/list;, {
}, 'Accept' = 'text/x-json' );
$mech-request($req);
cmp_ok( $mech-status, '==', 200, 'open attempt okay' );
I get the error:
'Method GET not implemented for http' =
'//localhost/api/rest/artist/api/rest/artist/object'
Somehow my request path gets all messed up. I dumped out the $mech, and it
tells
me that $mech-base is indeed what I put. So is $mech-redirected_uri.

Your DBIC classes aren't connected to the Catalyst app at all.
Unless you've fallen into the trap of putting business logic in your
Controller classes.
See this as a good opportunity to refactor the logic back into the
Schema classes where it belongs (or to a set of business objects if that
suits your application better).
Your code will be better for it :-)

My current project uses HTML::FormFu config files for both validating user input and generating json which contains the data of a resultset or result row. I do not use the html generation capabilities of FormFu, just validation, filters, transformers, inflators and deflators. I wrote http://search.cpan.org/~perler/DBIx-Class-AsObject-0.09_01/ which is far from being stable. But it generates a perl object from a result row using a HTML::FormFu configuration file. I think Controller::DBIC::API lacks of the ability to do proper validation.

as bug fixes. Please test it with your apps to make sure everything
works, and report back here. If we don't hear anything about problems

To test, you can get the development release here.
http://search.cpan.org/CPAN/authors/id/M/MR/MRAMBERG/Catalyst-Runtime-5.7099_04.tar.gz
Below is the changelog since the latest stable release, note that
5.7015's bugfix already was in the development releases.
5.7099_04 2009-01-12 13:06:00
- Add environment hack for FastCGI under IIS (Simon Bertrang)
- Test for this and preexisting Lighty hack (Simon Bertrang)
- Change streaming test to serve itself rather than 01use.t,
making test
sync for engines easier (t0m)
- Workaround change in LWP that broke a cookie test (RT
#40037)
- Backport go() from 5.8 branch.
- Fix some Win32 test failures
- Add pt translation of error message (wreis)
- Make :Chained('../action') work (Florian Ragwitz)
- Fix forwarding to action object.
- Handle leading CRLF in HTTP requests sometimes sent by IE6
in keep-alive requests.
5.7099_03 2008-07-20 10:10:00
- Fix regressions for regexp fallback in model(), view() and
controller()
- Added the supplied argument to the regexp fallback warning
for easier
debugging
- Ensure ACCEPT_CONTEXT is called for results from component()
5.7099_02 2008-07-16 19:10:00
- Added PathPrefix attribute
- Removed Catalyst::Build; we've long since moved to
Module::Install
- Updated Catalyst::Test docs to mention the use of
HTTP::Request
objects (Rafael Kitover)
5.7099_01 2008-06-25 22:36:00
- Refactored component resolution (component(), models(),
model(), et al). We now
throw warnings for two reasons:
1) model() or view() was called with no arguments, and two
results are returned
-- set default_(model|view), current_(model|view) or
current_(model|view)_instance
instead
2) you call a component resolution method with a string, and
it resorts to a regexp
fallback wherein a result is returned -- if you really
want to search, call the
method with a regex as the argument
- remove 0-length query string components so warnings aren't
thrown (RT #36428)
- Update HTTP::Body dep so that the uploadtmp config value
will work (RT #22540)
- Fix for LocalRegex when used in the Root controller
- Get some of the optional_* tests working from dirs with
spaces (RT #26455)
- Fix Catalyst::Utils::home() when application .pm is in the
current dir (RT #34437)
- Added the ability to remove parameters in req-uri_with() by
passing in
an undef value (RT #34782)
- Added $c-go, to do an internal redispatch to another
action, while retaining the
contents of the stash
