NAME Catalyst::Component::ACCEPT_CONTEXT - Make the current Catalyst request context available in Models and Views. VERSION Version 0.07 SYNOPSIS Models and Views don't usually have access to the request object, since they probably don't really need it. Sometimes, however, having the request context available outside of Controllers makes your application cleaner. If that's the case, just use this module as a base class: package MyApp::Model::Foobar; use base qw|Catalyst::Component::ACCEPT_CONTEXT Catalyst::Model|; Then, you'll be able to get the current request object from within your model: sub do_something { my $self = shift; print "The current URL is ". $self->context->req->uri->as_string; } WARNING WARNING WARNING Using this module is somewhat of a hack. Changing the state of your objects on every request is a pretty braindead way of doing OO. If you want your application to be brain-live, then you should use Catalyst::Component::InstancePerContext. Instead of doing this on every request (which is basically what this module does): $my_component->context($c); It's better to do something like this: package FooApp::Controller::Root; use base 'Catalyst::Controller'; use Moose; with 'Catalyst::Component::InstancePerContext'; has 'context' => (is => 'ro'); sub build_per_context_instance { my ($self, $c, @args) = @_; return $self->new({ context => $c, %$self, @args }); } sub actions :Whatever { my $self = shift; my $c = $self->context; # this works now } 1; Now you get a brand new object that lasts for a single request instead of changing the state of an existing one on each request. This is much cleaner OO design. The best strategy, though, is not to use the context inside your model. It's best for your Controller to pull the necessary data from the context, and pass it as arguments: sub action :Local { my ($self, $c) = @_; my $foo = $c->model('Foo'); my $quux = $foo->frobnicate(baz => $c->request->params->{baz}); $c->stash->{quux} = $quux; } This will make it Really Easy to test your components outside of Catalyst, which is always good. METHODS context Returns the current request context. ACCEPT_CONTEXT Catalyst calls this method to give the current context to your model. You should never call it directly. Note that a new instance of your component isn't created. All we do here is shove $c into your component. ACCEPT_CONTEXT allows for other behavior that may be more useful; if you want something else to happen just implement it yourself. See Catalyst::Component for details. COMPONENT Overridden to use initial application object as context before a request.
