NAME

Mango::Catalyst::Controller::Form - Catalyst controller for form based activity.

SYNOPSIS

package MyApp::Controller::Stuff;
use base qw/Mango::Catalyst:Controller::Form/;

sub edit : Local {
    my ($self, $c) = @_;
    if ($self->submitted) {
        my $results = $self->validate;
        if ($results->success) {
            ...
        };
    };
};

DESCRIPTION

Mango::Catalyst::Controller::Form is a base Catalyst controller that automatically loads forms based on the current class/action using Mango::Form.

By default, this controller loads all forms from a directory named after the current controller in the root/forms directory and assigns them to the actions in that controller matching the name of the form file themselves.

For example:

## controller
MyApp::Controller::Foo::Bar;

## directory/files
root/forms/foo/bar/create.yml
root/forms/foo/bar/edit.yml

## actions
sub create : Local {
    $self->form; ## create.yml form
};

sub edit : Local {
    $self->form; ## edit.yml form
};

IF you would like to load forms from a different directory, specify that directory using the form_directory configuration option below.

head1 CONFIGURATION

The following configuration options are used directly by this controller:

form_class

The form class used to parse/validate forms. The default class is Mango::Form.

__PACKAGE__->config(
    form_class => 'MyApp::Form'
);
form_directory

The directory to load forms from. If no directory is specified, forms in the current class2prefix are loaded instead.

__PACKAGE__->config(
    form_directory => '/path/to/this/classes/forms'
);

METHODS

COMPONENT

Creates an instance of the current controller and loads all available forms from the appropriate directory.

ACCEPT_CONTEXT

Accepts the current context and stores a weakened reference to it. This is just a hack so $self->form can access context without having to call $c->forward('form') all the time.

form

Arguments: $name

Gets the form for the current action.

sub edit : Local {
    $self->form; ## root/forms/controller/name/edit.yml
};

If you wish to work with a specific form, simply pass the name of that file, without the .yml extension, to form:

sub foo : Local {
    $self->form('edit'); ## root/forms/controller/name/edit.yml
};

When a form is returns, the following are set automatically:

params are set to $c->request
action is set to $c->action
localizer is set to $c->localize

form_class

Arguments: $class

Gets/sets the form class to be used when loading/validating forms. The default class is Mango::Form.

__PACKAGE__->form_class('MyApp::Form');

form_directory

Arguments: $directory

Gets/sets the form_directory where forms should be loaded from.

__PACKAGE__->form_directory('/path/to/controllers/forms/');

submitted

Returns true if the current form has been submitted, false otherwise.

sub edit : Local {
    my ($self, $c) = @_;
    if ($self->submitted) {
        ...
    };
};

validate

Returns a Mango::Results object containing the status of the current form validation.

sub edit : Local {
    my ($self, $c) = @_;
    if ($self->submitted) {
        my $results = $self->validate;
        if ($results->success) {
            ...
        } else {
            print @{$results->errors};
        };
    };
};
