[Catalyst-dev] more intelligence inside $c->uri_for()

[Wolfgang Kinkeldei]

Hi everyone,

currently I am building a small JS/CSS-combining and minifying  
controller. To build my URI I am doing business as usual:

   $c->uri_for(MyApp->Controller('Js')->action_for('default'), qw 
(list of js-files to combine));

yielding (after some hacks) a URI like:

   http://localhost/js/list/of/js-files/to/combine.js?m=12345667

which works fine. However, I would like to automatically get added a  
Query-Parameter after the URI that reflects the timestamp of the most- 
recent file in the URI to allow the browser to do caching properly.  
As far as I understand there is currently no way to let the  
Controller construct the URI.

As a bad hack, I did something like:

# in my App:
around 'uri_for' => sub {
     my $orig = shift;
     my $c = shift;
     my $path = shift;
     my @args = @_;

     if (blessed($path) && $path->class && $path->class->can 
('uri_for')) {
         # simply let the component do the job
         return $c->component($path->class)->uri_for($c, $path, @args);
     }

     return $c->$orig($path, @args);
};

# in my Controller:
sub uri_for :Private {

   # logic to create the URI I want

}


Of course it is great that Catalyst allows something like that. Are  
there any plans to offer something alike out of the box?
