NAME

Catalyst::Action::RenderView - Sensible default end action.

CONTENTS

SYNOPSIS



    sub end : ActionClass(RenderView) {}



DESCRIPTION

This action implements a sensible default end action, which will forward to the first available view, unless $c->res->status is a 3xx code (redirection, not modified, etc.), 204 (no content), or $c->res->body has already been set. It also allows you to pass dump_info=1 to the url in order to force a debug screen, while in debug mode.

If you have more than one view, you can specify which one to use with the default_view config setting and the current_view and current_view_instance stash keys (see Catalyst’s $c->view($name) method — this module simply calls $c->view with no argument).

METHODS

    end

The default end action. You can override this as required in your application class; normal inheritance applies.

INTERNAL METHODS

    execute

Dispatches control to superclasses, then forwards to the default View.

See METHODS/action in Catalyst::Action.

SCRUBBING OUTPUT

When you force debug with dump_info=1, RenderView is capable of removing classes from the objects in your stash. By default it will replace any DBIx::Class resultsource objects with the class name, which cleans up the debug output considerably, but you can change what gets scrubbed by setting a list of classes in $c->config->{’Action::RenderView’}->{ignore_classes}. For instance:



    $c->config->{Action::RenderView}->{ignore_classes} = [];



To disable the functionality. You can also set config->{’Action::RenderView’}->{scrubber_func} to change what it does with the classes. For instance, this will undef it instead of putting in the class name:



    $c->config->{Action::RenderView}->{scrubber_func} = sub { undef $_ };



    Deprecation notice

This plugin used to be configured by setting $c->config->{debug}. That configuration key is still supported in this release, but is deprecated, please use the Action::RenderView namespace as shown above for configuration in new code.

EXTENDING

To add something to an end action that is called before rendering, simply place it in the end method:



    sub end : ActionClass(RenderView) {
      my ( $self, $c ) = @_;
      # do stuff here; the RenderView action is called afterwards
    }



To add things to an end action that are called after rendering, you can set it up like this:



    sub render : ActionClass(RenderView) { }

    sub end : Private {
      my ( $self, $c ) = @_;
      $c->forward(render);
      # do stuff here
    }
