Re: [Catalyst] running a function once on all requests

Instead of the first, it gives me last controller in the chain, which leads

It runs for all controllers in the hierarchy, top-most first. Even if
it ran the other way around, you'd still get the wrong result because
you're calling $c->namespace, which gives you the namespace of the
current running action, you want $self->namespace instead.
Perhaps there is a different approach with autochaining I should try.
you could do something like:
sub auto : Private {
my($self, $c) = @_;
push @{$c->stash->{controllers}}, $self->namespace;
return 1;
}
# in Root
sub end : Private {
my($self, $c) = @_;
$c->stash{controller} = $c->stash->{controllers}[0];
}
Although I'm not sure if this is the best way to do it, I'd much
prefer this over subclassing since things can get messy if you need to
inherit from another controller like FormBuilder or REST.

The solution was to create a schema instance like so,

Then do the transaction
$schema->txn_do($coderef);

connections around that I could use rather than manually connecting each

You don't have to connect every time. Catalyst::Model::DBIC::Schema
connects when your catalyst application launches and does its best to
preserve the connection for you. You can get to the schema instance
via $c->model()
The docs for Catalyst-Model-DBIC-Schema say
# to access schema methods directly:
$c->model('FilmDB')->schema->source(...);
When I try a similar thing,
$c->model('kRadDB')->schema
I get this error " Can't call method "schema" without a package or object
reference"
You need to ask for the model name that inherits from
Catalyst::Model::DBIC::Schema, the one that has __PACKAGE__->config(
schema_class => 'kRadDB', config_info => '...' ) in it, not the schema
class.

[Catalyst] Debug/Warning messages for duplicate files under M/V/C directorios
Greetings everyone, I stumbled onto an annoying problem this week, a co-worker of mine somehow managed to duplicate the lib tree into lib/MyApp/Controller which, of course caused the app to crash before I got the initial debug messages, since the log only flushes after the entire app loads, so it took me quite a while to figure it out. While I was whining about the problem in #catalyst, mst suggested there should be helpful debug messages to deal with this kind of issue. Simply flushing the log as each component loads doesn't help a lot since the duplicate file can be loaded before the real one, in that case, the 'redefine' warnings aren't very helpful. Ideally, the debug messages should report which two components tried to load the same thing. I've done something like this by walking the symtable every time a component loads, but that sounds like overkill.

Hi,
I often need to make external redirections like in the following case:

When I access /user/logout for executing this subroutine, it prints the
following error:
Coldn't render template "file error - user/logout: not found"
So I need to add a template in the stash in this subroutine, even though I
don't want to use and print any template, but just do the redirect.
If I add before redirection:
$c->stash->{template} = "index.tt";
all works fine, but I guess something is not right in this code.
Isn't there a way to just stop everything and make the redirection, without
executing the end action?
No, there isn't. Catalyst only emits the response after all the
actions are dispatched. One way you can keep the end action from
running is by not having one. In your case, set up a Controller
without an end action just for authentication. In there, you can set
up Path actions so you don't have to rewrite all the URLs you've
already got in your code:
sub logout : Path('/user/logout'){
my ($self, $c) = @_;
$c->logout;
$c->res->redirect($c->uri_for('/'));
}

Thanks any way.
It works if you manage to run your stuff after Catalyst calls
$c->finalize() in handle_request(). Funny, I just wrote a hack, err,
plugin yesterday which gives me the option to set up a hook that's
called right after $c->finalize(). I'm not sure if this is the correct
way to do it or if there are any side-effects, if any of the more
experient Catalyst users/developers think its a good idea for a
plugin, let me know and I'll can carve it up and release it.
I use mod_perl and haven't had any trouble so far, this approach lets
me delegate all the pre-fork management to apache. I have a Catalyst
front-end which adds jobs to a queue like mentioned before in the
thread and a another Catalyst server running XMLRPC that gets notified
about incoming jobs and runs them after responding to the XMLRPC
notification.
In MyApp.pm:
use Catalyst qw/AfterFinalize/;
In a controller action somewhere:
sub myaction : Local {
$c->res->body('running job');
$c->after_finalize(sub { run_job() } );
}

Not really, no, the MVC pattern is actually just a specialized Adapter pattern so you can program your Views and Models independently without having to conform the Application and its Presentation to a specific interface.

Catalyst is very flexible, you can put your mapped DB classes wherever you want, you could even have a View that's mapped to a database that stores your templates or even your application data if you want.

I'd stick to the fundamental OO Pattern theory: program to interfaces not implementations. Personally, I have my Controller actions call operations from a Model class interface and my aplication logic stays in the Model, behind the interfaces I defined.
