MooseX::MojoControllerExposingAttributes - Expose controller attributes to Mojolicious


version 1.000001


    package MyApp::Controller::Example;
    use MooseX::MojoControllerExposingAttributes;


    has some_attribute => (
        is     => 'ro',
        traits => ['ExposeMojo'],

    # then later in a template: <%= ctrl->some_attribute %>


This module is for advanced use. $c/$self are already made available in templates and are likely sufficient for the majority of use cases. This module was created in order to expose Moose attributes in a way where you don't have to stash them every single time you want to use them.

This class allows you to expose selected Moose attributes from your Mojolicious controller to your templates by marking them with the ExposeMojo trait.

Using this class in a Perl class does several things:

It makes the class a subclass of Mojolicious::Controller
It sets up the class with Moose and Moose::NonMoose
It applies the extra role and metaclass traits to the class so this works with Mojolicious::Plugin::ExposeControllerMethod
It sets up the ExposeMojo trait

So rather than declaring your controller class a Moose Mojolicious Controller in the usual way:

   package MyApp::Controller::Example;
   use Mojo::Base 'Mojolicious::Controller';
   use Moose::NonMoose;
   use Moose;

You should simply say:

   package MyApp::Controller::Example;
   use MooseX::MojoControllerExposingAttributes;

Once you've done that then you can define attributes in the class (or in roles the class consumes) that are exposed to Mojolicious.

  has some_attribute => (
      is     => 'ro',
      traits => ['ExposeMojo'],

  has some_attribute_with_a_really_long_name => (
     is                => 'ro',
     traits            => ['ExposeMojo'],
     expose_to_mojo_as => 'shorter_name',

In order to get the ctrl helper you should make sure you've loaded the Mojolicious::Plugin::ExposeControllerMethod plugin somewhere in your Mojolicious application, typically within the startup method itself:

    sub startup {
        my $self = shift;



Then you'll be able to access your attributes from within templates that are rendered from that controller:

   some attribute: <%= ctrl->some_attribute %>
   some attribute with a really long name: <%= ctrl->shorter_name %>


It would be nice to be able to set the baseclass instead of always using Mojolicious::Controller
