Re: [Catalyst] Changing format of date field
I suggested that you extend DBIx::Class::InflateColumn to create
DBIx::Class::InflateColumn::MyDateTime to give you the result you need.
However, I would state that although I have shown you how to do this,
personally I would keep decisions about how to display data where it
belongs, in the view, and stay with the object.dmy() which makes it quite
clear your intent, rather than doing it 'at a distance' in the model.
Kind Regards

So you mean copy DBIx::Class::InflateColumn::DateTime under my lib/

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? Craig. Yes, try to keep it out of the Controller. My opinion is, that if you have business logic that uses data from two SQL servers (each of which has it's own model) then this would be a model in it's own right. First think of this business logic outside of Catalyst, it might have accessors for each of the SQL instance objects. Create a BusinessModel for this logic. You might find that this then becomes the only Model that you need to access from Catalyst, and the SQL server objects are not directly called from Catalyst, but are subsumed by BusinessModel. Then use Catalyst::Model::Adaptor with your BusinessModel giving Catalyst access to all of it's methods.

I suspect you have not configured your View::JSON correctly.
Ensure you have it configured in your equivalent to MyApp.pm as follows.

and it should then do what you want.

Re: [Catalyst] Format last modified date field ...
Kiffin
It looks to me like when you print the date field it is doing
stringification of the DateTime object.
Try doing
user.last_modified.ymd
In your template and see what you get. If you get something like
'2009-12-28' then you can output any of the formats that DateTime supports.

[Catalyst] Advice on namespace for a potential Catalyst cpan module
WRT my previous post I now have a module for a Moose Role useable in a Catalyst Controller to manage breadcrumb trail navigation. The module automatically builds up a breadcrumb trail as you navigate through the web application and can then be used to produce an ordered list of the pages you have visited. This aids navigation since you can click on any of the previous pages visited. A bit like a browsers history. This might be something worth of putting on cpan. If so what would be a suitable namespace? CatalystX::BreadCrumb springs to mind or perhaps CatalystX::Controller::BreadCrumb since it is a role to be used in Controllers. Or are there any other 'standards' for Moose Role modules?

[Catalyst] Just a hint on using Roles
Hi I am looking at creating a generic Breadcrumb module to use with Catalyst. The basic idea being that some controllers will 'reset' a breadcrumb path back to the start (for example when clicking on a main menu) and some controllers will append to the existing breadcrumb. e.g. Main menu item linking to /users will display a list of all users (reset breadcrumb) Clicking on a link on that page to go to /user/123 will append the new URI to the breadcrumb, /user/123/edit appends again. etc. I would then be able to create a BreadCrumb Role that could be used with some of my controllers to maintain a breadcrumb structure on the stash that could then be used in my templates? ISTM that this is an ideal application of Roles? I would welcome comments if this is a sensible approach and I can research the details further myself.

package MyApp::Controller::Admin;

Hi,
If using mod_perl, instead of:
Location /
SetHandler perl-script
PerlResponseHandler MyApp
/Location
use:
Location /foo
SetHandler perl-script
PerlResponseHandler MyApp
/Location
And the application should work at the new location.
Thanks, that did the trick. I was looking for something more complicated!
But if in the templates you use urls like:
a href=/user.../a
you need to change them to urls like:
a href=[% c.uri_for('/user') %].../a
If you use fastcgi, instead of:
FastCgiExternalServer /tmp/myapp.fcgi -socket /tmp/myapp.socket
Alias / /tmp/myapp.fcgi/
you could use:
FastCgiExternalServer /tmp/myapp.fcgi -socket /tmp/myapp.socket

I have what I hope is not a dumb question. I'm trying to follow best

should be Catalyst agnostic and therefore am creating a custom model.
(However, at the moment Catalyst is the primary consumer of this lib.)
I'd like to use my DBIC::Schema goodness for DB access and happily
have abstracted that via Catalyst::Model::DBIC::Schema. The thing is I
realized that if I connect to this schema outside of the scope of
Catalyst via DBIx::Class::Schema-connect I have to pass in the
connection info separately which really bugs me because I've already
defined it via a configuration file for the Catalyst app (using
Config::General). I suppose I could just pass that info into the model
but that seems messy and redundant to me. If I subclass
Catalyst::Model well then I'm tightly coupled with Catalyst again. I'd
like to just be able to glue the model to Catalyst and do a:
$c-model('MyCustomModel')-foo(...)
and it just work.
It seems to me there should be a simple way for this schema to know
its connection info based on context and I figured there's like a
slick Catalyst ninja kind of method for doing this that my brain is
just not grasping at the moment. How do you do this sort of thing? Is
the magic in the Catalyst glue?
Thanks in advance for any advice/thoughts/comments...

I use an external yaml file to hold connection information. In that way
I can easily have different
configurations for different environments, dev, staging, live.
# production database access
DBIxProd:
dsn:'DBI:mysql:host=localhost;database=myapp_prod'
username: fred
password: secret

In my Catalyst model I do something like.
package myapp::Model::DBIxProd;
use strict;
use base 'Catalyst::Model::DBIC::Schema';
__PACKAGE__-config(
schema_class= 'myapp::Storage',
connect_info = [
myapp-config-{DBIxProd}{dsn},
myapp-config-{DBIxProd}{username},
myapp-config-{DBIxProd}{password},
{ 'mysql_enable_utf8' = 1 },
{ on_connect_do =[ 'set names utf8' ] },
]);

And in my external app (usually in a 'tools' subdirectory) I do

Re: [Catalyst] testing catalyst app - need context
Kate Yoak wrote:
Hi there,
Here is a newbie question:
I like to test my functionality in bits and pieces as I write it. How
do I go about getting myself the context object in a test script?
For example, one of the tests catalyst installs is t/model_App.t where
it loads the model. I'd love to then be able to use the model the same
way a controller would:
my $acc = $c-model('Account')-find(1);
Instead, I am doing
my $model = MyApp::Model::App-new();
my $acc = $model-recordset('Account')-find(1);
In addition to being less than ideal because I am doing something
different that I expect real application code to do, it presents
configuration problems. Like, turns out, in order for config to take
effect, I have to run __PACKAGE__-setup; after configuring it - which
won't be necessary, I think, in a real app.
Is the practice of unit tests that break up the layers of catalyst
frowned upon? Or what should I do to make it work right?
Best practice is to keep your model separate from Catalyst so that you
can (for example) create batch scripts or cron
jobs that work on the model without having to load the whole of Catalyst
Your model then would be in something like MyApp::Storage and accessed
by your tests as so...
my $schema = MyApp::Storage-connect(
'DBI:mysql:host=localhost;database=my_database',
'username',
'password',
{ 'mysql_enable_utf8' = 1 },
{on_connect_do =[ 'set names utf8' ] }
);
my $acc = $schema-resultset('Account')-find(1);
You would be testing your database layer separately from Catalyst.
Your Catalyst Model would then look something like.
package MyApp::Model:MyDB;
use strict;
use base 'Catalyst::Model::DBIC::Schema';
my $dsn = 'dbi:mysql:port=3406:host=localhost';
__PACKAGE__-config(
schema_class = 'MyApp::Storage',
connect_info = [
$dsn.';dbname=my_database',
'username',
'password',
{ 'mysql_enable_utf8' = 1 },
{ on_connect_do =[ 'set names utf8' ] },
],
);

Re: [Catalyst] Authorization header and fastcgi
Mark.
I was not looking at $c-engine-env, but now that I am, there is no
Authorization or HTTP_AUTHORIZATION there either.
I have decided to side-step this issue and create an 'Authentication'
header rather than an 'Authorization' header and to hell with the
'standard'.
(Besides the 'standard' is badly named anyway!)
Thanks everyone for help with this matter.

Re: [Catalyst] How much chain?
Thomas Klausner wrote:
... do I need to hang myself?
I'm (finally) playing around with chained, and like it very much.
But now I have some sort of design question, on which I'd like to
collect some feedback:
Say, you want to edit things. The general way of editing is the same for
most things, only the thingies you want to edit differ (i.e. their
fields).
(slightly OT, but some background: We want to use HTML::FormFu
for actual form generation, but do not want to use the config-file
aproach, but something like a 'registry' where each field and it's
definition is stored (basically we have several different things using
similar fields...))
What to you think is better:
A) lots of chain
package Thing:
use base 'Generic';
sub base : Chained('/') PathPart('thing') CaptureArgs(0) {}
sub setup_fields : Chained('item') CaptureArgs(0) {
# define a list of fields and store them in stash
}
package Generic;
sub item : Chained('base') PathPart('') CaptureArgs(1) {
# load thing and store in stash
}
sub show_form : Chained('setup_fields') Args(0) {
# take field list, make form, etc
}
I'd end up with an URL like
/thing/123/setup_fields/show_form
I really don't think you should expose your implementation in your URI.
For example if in the future you decide to re-write your system to not
use FormFu and not have a setup_fields and a show_form method you have
to change your interface. It is rather like the advantages you get by
encapsulation in OO programming, you can change the internal
implementation without worrying about the interface.
B) Plain Old Methods
package Thing:
use base 'Generic';
sub base : Chained('/') PathPart('thing') CaptureArgs(0) {}
sub edit : Chained('item') Args(0) {
my ($self, $c) = @_;
$self-setup_fields($c, ... );
$self-make_form;
#
}
package Generic;
sub item : Chained('base') PathPart('') CaptureArgs(1) {
# load thing and store in stash
}
sub setup_fields {}
sub make_form {}
sub handle_form {}
I'd end up with an URL like
/thing/123/edit
which IMO looks nicer.
And IMO too. this is exactly how to use chaining. Don't hang yourself by
trying to use chaining for everything.
So, is A) just overdoing chained? B) looks ok, but is it using chained
to it's full potential?
It is using chaining to it's full potential (given the simple example
you gave) but in a more complex example, e.g.
/manufacturer/123/component/456/subcomponent/789/edit
it would be clearer that chaining is going to make something like this
much easier by putting the manufacturer object on the stash, then the
next chain puts the component object on, then the subcomponent, then it
chains to the 'edit' controller.
I'd really like to hear some of your thoughts...

Well, I'm sure there's a somewhat elegant way to do this with Chained,
but it the other controllers don't use Chained now, that could get fun.
I have considered chained, and would be prepared to re-write the
existing controllers. A bigger decision would be renaming the
controllers or moving them.
e.g. existing MyApp::Controller::Foo::Bar maps to URI /foo/bar
To match against /lang/foo/bar either I can leave the controller where
it is (lib/MyApp/Controller/Foo/Bar.pm) or move it
(lib/MyApp/Controller/Lang/Foo/Bar)
The first approach is less work (only using chained) the second is more
work, but maps the URI namespace more logically to the Class names.
What would people do if they were writing a Catalyst App from scratch
with this feature? That would tell me what the 'best practice' is even
if it means a big re-write exercise.
The brute force way is to inspect the request and rip out the language
portion before sending it on to get dispatched...just like the Flavour
plugin does with file extensions:
sub prepare_path {}
One of my pet peeves is exemplified in the 'Flavour' plugin. It is such
minimal documentation that it neither tells you what it does or why it
does it. OK, I can look at the code, but it is too much effort unless I
think I have a good reason to do so. I assume in this case that it is
something to do with date strings in the URI (for blogging?). I can't be

It does just what just what Bill suggested.
I check if the prefix is a valid language (if it's one of the language
files I loaded at startup), if so I then remove it from the request
path and append it to the request base.
In prepare_path.. you inspect the requested path.. yank out the
language.. then pass along the remaining path...which should map to
your existing controllers just fine.
I have actually taken a look at the Flavour plugin (can't see for the
life of me why it is called that!) and it gives an example of yanking
off the //mm/dd at the start of a path, putting the values into
accessors of flavour (e.g. $c-flavour-year) leaving the rest of the
path to be processed as normal. This is pretty much what I want to do
for the language so thanks for pointing out the plugin to me.
I am pretty confident that I can now write a plugin to strip out a
language from the start of a path in the same way.
Looking at the Catalyst best practices, am I going to be polluting the
catalyst namespace by writing this as a plugin? I can't see any
alternative (making it a base Controller is actually what I am trying to
avoid).
Any suggestions as to a namespace for this? Catalyst::Plugin::LangURI
perhaps?
As far as chained goes... I thought there was an example floating
around that has Root::lang as Chained, then all other modules Chaine
against /lang as their root instead of /...
I should not need this if I do the above then I can leave my existing
controllers unchanged (and unchained).

Having read the other postings on this I wonder if you have a large-ish css or Javascript file being loaded. I've noticed a bit of a delay when I was trying the Ext2.js examples from the Ext2 site. This delay is related more to the complexity of the javascript than it's size. It's essentially the compile-time penalty of the library in use, ExtJS is one of the bigger ones that I've noticed it on, it can take quite a while for it get loaded/decompressed/setup and ready to go. It's much faster when using a release version rather than a testing version, and there are tools that will let you build custom ExtJS versions with just the features you are actually using included, so you don't have to wait for initialization for features you aren't using. I am using extjs and realised that this could be an issue but I created a brand new minimal Catalyst application and I saw the same issues. Also I used wget to get the web page, which of course does not execute the javascript. The 15 second long delay is prior to the Catalyst debug information being printed. The actual execution of the various controllers is very quick (sub 0.3 seconds) If I use CATALYST_DEBUG=0 then the problem goes away. Lately, the problem has gone away even without turning debug off. One possibility I am still investigating is that the problem only occurs if two or more developers are running a server at the same time.

Re: [Catalyst] Re: REST - like uri design for CRUD
Aristotle Pagaltzis wrote: * Ian Docherty [EMAIL PROTECTED] [2008-01-28 13:45]: OK, so I put the item into the request body, but this does not tell the remote client the ID of the created item. Why does it need it? Is the URI not enough? If not, is the URI *really* not enough (ie. could things be arranged so that it is)? The 'create' is a POST to the URI http://mydomain.com/svc/doc with the content being the document to save. However, the client has to know the ID of the created document (which at this point is only known by the server). Say for example that I am putting arbitrary documents (xml, text, images) etc. onto the server via a web service in a RESTful manner, I do this with a POST to my server. The server needs to respond with something in the header to indicate the ID of the document just POSTed. Well, then don’t render the body of the item in the 201 response, and do not set Content-Location, and instead just put some JSON or XML or whatever in there. OK, this would have been my first choice but I was misled I think by some other threads. I do this in the Location header. Location may only ever be a URI. If you put anything else there, you’re doing it wrong. Yes I agree. e.g. POST /svc/upload (the document save) Location /svc/view/1234 (the location of the item just saved, ID=1234) So the URI is parsed by the programmatic client to extract the '1234' yes/no? No. Clients should never parse URIs. If you need to tell them something they need to be able to understand, you put it in the body. (They should not construct URIs either. If they need to request parametrisable URIs, the server should send them a form. Or if you’re creating a non-browser HTTP API, you can send the client a URI Template.) This is something I have not seen mentioned before. I have no idea what a 'URI Template' would look like. I don't see what is wrong with 'constructing' a URI, e.g. what is wrong with the client 'knowing' that URI http://mydomain.com/svc/view/1234 is the location to retrieve item 1234? This is the hypermedia constraint in REST: clients only follow links and forms. They don’t have any hardwired knowledge of the server URI space. (Note, though, that things get muddled with Ajax clients. If the Ajax client is code served by the server (called _Code on Demand_ in REST), then it’s effectively a Turing-complete kind of form markup, so it’s fine for that code to have hardwired knowledge. But in practice, the Ajax client probably talks to a publically available HTTP interface, and making that interface require hard- wired knowledge of non-Code-on-Demand clients is wrong, so it’s probably better to follow the hypermedia constraint even in on- demand code.)

Re: [Catalyst] How to return a 401 from Catalyst
Ian Docherty wrote:
Related to my earlier thread about basic authentication, what do I
have to do to return a 401 error from within Catalyst?
I have tried to understand the documentation at
http://www.ietf.org/rfc/rfc2617.txt but it does not help me in a
practical manner.
My understanding is that when the Catalyst app refuses the credentials
given it must return a 401 with a 'realm' that is
just a string used to identify the service.
For example, when I create a test script for my Controller using LWP
as follows
my $ua = LWP::UserAgent-new;
$ua-credentials('linux:8001','some_realm_or_other','sage_1001','sage');
Then my script fails because I have not set a 'realm' correctly in my
Catalyst controller. All I have done so far is as follows.
if ($login_success) ) {
# do something
}
else {
$c-response-status(401);
return 0;
}
Obviously I need to do more to return the realm, but what exactly?
Answering my own question after a bit of digging around.
It seems that all that is needed is to return the appropriate header as
follows.
$c-response-header('WWW-Authenticate' = 'Basic realm=My
Realm');
$c-response-status(401);
return 0;
Simple really ;)
Regards
Ian
p.s. I note that there is nothing in Test::WWW (that I can find) that
tests return status's such as 200, 401 etc.

[Catalyst] $c-req-body oddity
I am sending a POST to a Catalyst app and according to the documention I
expected the request body to
contain the data I sent. Instead it holds a filename in the tmp
directory which contains the document. Is
this an expected behaviour?
e.g. in my test script
my $request = HTTP::Request-new(POST = 'http://linux:3000/svc/to/1001');
$request-content_type('text/text');
$request-content('THIS IS THE STRING');
my $response = $ua-request($request);
If I look at the value in $c-request-body in my controller I get
something
like '/tmp/LEVo4ciz1g'
And if I look at the content of the temp file I find my 'THIS IS THE
STRING'
text.
Is this a document problem or something else?

Re: [Catalyst] Authentication for web services (slightly off topic)
Thanks to Andrew Page for this suggestion.
By running the Catalyst server and using wget to get the page the
Controller recognises the username and password
wget --http-user=sage --http-password=s3cr3t http://linux:8001/svc/status
output
Authorization [sage][s3cr3t]
If I run the Catalyst server and then run my test as follows.
CATALYST_SERVER=http://linux:8001 make test
Then the output is
Authorization [][]
So, it appears that the problem is with my test script not passing the
credentials to the Catalyst App.
I will carry on working on this but any other suggestions are welcome.

Ian

[Catalyst] Authentication for web services (slightly off topic)
This might seem like a stupid question, and one that probably has a simple solution. If I am serving XML over HTML (a simple web service), how do I authenticate the client? I would not expect cookies to be a sensible solution. I could use Apache Basic Authentication, but I would prefer to hold usernames passwords in a database rather than a htpasswd file. That's about the limit of what I can think of. The second question (and the reason why this is still on-topic) is that I want to have a web application and a web service running from the same Catalyst application. So, if I had a URL with a pre-path of http://mydomain.com/service then this would be directed to the web services (with their own authentication) and anything else would be directed to the web application (with standard username-password login). Is it feasible to authenticate these using two different methods in Catalyst?
