Re: [Catalyst] How to execute controller at startup
Hi All,
Thank you very much for all your valuable comments at appreciate your quick
response.
I have one more query.
I have implemented a Plugin. How can I call a plugin method from controller
outside of the controller methods.
suppose i have a Plugin named Catalyst::Plugin::MyPlugin contains a method
called sub myFunc {}
Now i want to call myFunc from controller but i dont have context object
outside of methods so currently I am doing:
Catalyst::Plugin::MyPlugin::myFunc();
which is a normal function call (not catalyst way of doing, not even object
oriented).
Could you please suggest me an efficient way to call that method.
Thanks,
Aditya

Hi,
Catalyst Controllers are subclasses of
Catalyst::Component so are automatically located a
registered by your primary Catalyst class at startup.
If you are finding that you don't see your controllers
and/or actions in the debug screen when you start the
development server then you must have some typos in
the controller package names or something similar.
Please give us a little more detail about your trouble
and the actually need that you are trying to fill.

[Catalyst] TT macro to avoid excessive $c-uri_for calls
I'm wondering if it has any bad side effects to have a TT macro which is set to
$c-uri_for. If I'm remembering previous posts on this topic correctly, calling
uri_for() repeatedly has quite a big impact on performance which really matters
most for my current application. I have this in a global macros.tt2 file:
[%
base = Catalyst.req.base;
static = Catalyst.config.hosts.static;
images = Catalyst.config.hosts.images;
site.url = {
base= base
static = static
images = images
}
-%]
That way I can easily change the location of my static files and images to
another server or place using the Catalyst config file and generate links like
this:
img src=[% site.url.images %]logo.png /
a href=[% site.url.base %]user/whateverbla/a
etc.
Any comments? Thanks!

Redefine is the term in perl-lingua.
Not really, it's just subclassing.
Catalyst plugins (like DBIC components) just end up as extra superclasses
In MyApp.pm:
{
no warnings 'redefine';
# this line is completely pointless.
sub merge_session_to_user {
# your new sub
# ...
# To call the previous implementation if you should want it:
# $self-NEXT::merge_session_to_user(@args);
}
}
The key thing to remember here is that all Cat plugins 'pollute' the $c
namespace, which isa Myapp.
They end up on your @ISA, this polluting the namespace of potential method
names, but they don't pollute the MyApp package directly - that level of
stupidity I haven't seen since Class::DBI::Plugin::*

Since I'm not sure what your use case is I can only
give you some vaguely general suggestions.
First of all, the community has lately pushed people
to look carefully at their plugins to see if they are
really plugins or something else. There is a document
posted at:
http://search.cpan.org/~jrockway/Catalyst-Manual-5.700701/lib/Catalyst/Manual/ExtendingCatalyst.pod
which is a a MUST READ for all new developers.
If you have something locked up in a plugin that you
need elsewhere, like in a cron job, for example, that
probably belongs in a Plain old Perl class and brought
into Catalyst via a Model. That way you can access
functionality outside of Catalyst.
For (very brief) example:
A Plain Old Perl module:
package Myapp::Somestuff;
use base 'Class::Accessor';
sub stuff {
my ($self, $arg) = @_;
return $arg x 2;
}
A Catalyst model to wrap this:
package Myapp::Web::Model::Somestuff;
use Class::C3;
use base 'Catalyst::Model';
__PACKAGE__-mk_accessors(qw/somestuff/);
sub new {
my ($class, $c, $arguments) = @_;
my $self = $class-next::method($c, $arguments);
$self-somestuff(Myapp::Somestuff-new());
return $self;
}
sub stuff {
shift-somestuff-stuff(@_);
}
In a controller:
Package Myapp::Web::Controller::Something;
use base 'Catalyst::Controller';
sub testit :Local {
my ($self, $c) = @_;
$c-stash(
result = $c-model('Somestuff')-stuff('a'),
);
}
And then in your template you have a stash key
'result' which is equal to 'aa'. And you have code
you can use outside of catalyst.
The above can be improved. For example you can use
AUTOLOAD to automatically map the wrapper methods in
your module:
(Lifted pretty much from Handle or Mango, I forgot)
sub AUTOLOAD
{
my $self = shift @_;
my @args = @_;
my ($method) = (our $AUTOLOAD =~ /([^:]+)$/);
return if $method =~ /(DESTROY|ACCEPT_CONTEXT)/;
return $self-somestuff-$method(@args) if
$self-somestuff-can($method);
}
Good luck!

Expanding on what mst said, keep in mind that plugins are reserved for
things that need to affect the request cycle. If you just need some
functionality, write a regular module. If it needs $c, pass in $c.
Component base classes are also possible, and are a better approach
than plugins. (See C::Plugin::FormBuilder
vs. C::Controller::FormBuilder. Both are on CPAN so you can compare
the approaches.)
Finally, phaylon's Extending Catalyst guide:
http://search.cpan.org/~jrockway/Catalyst-Manual-5.700701/lib/Catalyst/Manual/ExtendingCatalyst.pod
suppose i have a Plugin named Catalyst::Plugin::MyPlugin contains a method
called sub myFunc {}
That should be my_func, not myFunc. This is perl, not java. Please stick to
the correct naming conventions for things.
TMTOWTDI, but your way is rather unconventional. Identifiers should
be lowercase (%karma_for), constants should be uppercase
($SECRET_OF_THE_UNIVERSE), and modules should be CamelCase
(MyApp::SomeThing). Anything else will make people like mst mad
because it's really really ugly.
Hope this helps.

Jonathan Rockway
