Catalyst::Enzyme::CRUD::Controller - CRUD Controller Base Class with CRUD support


See Catalyst::Enzyme



The model class, overloaded by you in each controller class to return the actual class name for the Model this controller should handle.

So in your Controller classes, something like this is recommended:

    sub model_class {


These are the default CRUD actions.

You should read the source so you know what the actions do, and how you can adjust or block them in your own code.

They also deal with form validation, messages, and errors in a certain way that you could use (or not, you may have a better way) in your own Controller actions.

auto : Private

Set up the default model and class for this Controller

set_crud_controller : Private

Set the current Controller and it's Model class (and the Model's configuration using the model_class() ).

Point $self->crud_config to the Model's config->{crud}. Set crud_config keys:

 moniker (default)
 rows_per_page (default 20)
 column_monikers (default)

Set stash keys:

 crud (to the crud_config)
 controller_namespace (to the Controller's namespace)
 uri_for_list (to a version that accepts array refs from TT)

Return 1.


This action is automatically called by the auto action.

This means that if the user invokes an action in a Controller, the set_crud_controller is called properly and that Controller's Model class is used. No need to do anything.

If you forward between actions in the same Controller, the same Model class should be used, so no need to do anything.

But if you forward to an action in a different Controller, you need to tell Enzyme to start using the new Model class first. So, going from e.g. the Book Controller to a Genre action, you need to:



Forward to list.


Display list template


Select a row and display view template.


Display add template


Add a new row and redirect to list.


Display edit template.


Edit a row and redirect to edit.


Display delete template.


Destroy row and forward to list.



Return hash ref with a default Data::FormValidator config.


Return hash ref with config values form the Model class' config->{crud} (so model_class needs to be set).

model_with_pager($c, $rows_per_page, $page)

Return either the current model class, or (if $rows_per_page > 0) a pager for the current model class. $page indicates which page to display in the pager (default to the first page).

Assign the pager to $c->stash->{pager}.

The Model class (or it's base class) must use Class::DBI::Pager.

template_with_item($template, $c, $id)

Retrieve object with $id and set the $template. Suitable to call like this in an action (nothing else is needed):

    sub edit : Local {
       shift->template_with_item("", @_);
