        # Must return a hash-ref suitable to be fed to $form->populate()
    }

METHODS

form

This creates a new HTML::FormFu object, passing as it's argument the contents of the "constructor" config value.

This is useful when using the ConfigForm() or MethodForm() action attributes, to create a 2nd form which isn't populated using a config-file or method return value.

    sub foo : Local {
        my ( $self, $c ) = @_;
        
        my $form = $self->form;
    }

Note that when using this method, the form's query method is not populated with the Catalyst request object.

CUSTOMIZATION

You can set your own config settings, using either your controller config or your application config.

    $c->config( 'Controller::HTML::FormFu' => \%my_values );
    
    # or
    
    MyApp->config( 'Controller::HTML::FormFu' => \%my_values );
    
    # or, in myapp.yml
    
    ---
    'Controller::HTML::FormFu': {  }

form_method

Override the method-name used to create a new form object.

See "form".

Default value: form.

form_stash

Sets the stash key name used to store the form object.

Default value: form.

form_attr

Sets the attribute name used to load the Catalyst::Controller::HTML::FormFu::Action::Form action.

Default value: Form.

config_attr

Sets the attribute name used to load the Catalyst::Controller::HTML::FormFu::Action::Config action.

Default value: FormConfig.

method_attr

Sets the attribute name used to load the Catalyst::Controller::HTML::FormFu::Action::Method action.

Default value: FormMethod.

form_action

Sets which package will be used by the Form() action.

Probably only useful if you want to create a sub-class which provides custom behaviour.

Default value: Catalyst::Controller::HTML::FormFu::Action::Form.

config_action

Sets which package will be used by the Config() action.

Probably only useful if you want to create a sub-class which provides custom behaviour.

Default value: Catalyst::Controller::HTML::FormFu::Action::Config.

method_action

Sets which package will be used by the Method() action.

Probably only useful if you want to create a sub-class which provides custom behaviour.

Default value: Catalyst::Controller::HTML::FormFu::Action::Method.

constructor

Pass common defaults to the HTML::FormFu constructor.

These values are used by all of the action attributes, and by the $self->form method.

Default value: {}.

config_callback

Arguments: bool

If true, a coderef is passed to $form->config_callback->{plain_value} which replaces any instance of __uri_for(URI)__ found in form config files with the result of passing the URI argument to "uri_for" in Catalyst.

The form __uri_for(URI, PATH, PARTS)__ is also supported, which is equivalent to $c->uri_for( 'URI', \@ARGS ). At this time, there is no way to pass query values equivalent to $c->uri_for( 'URI', \@ARGS, \%QUERY_VALUES ).

The second codeword that is being replaced is __path_to( @DIRS )__. Any instance is replaced with the result of passing the DIRS arguments to "path_to" in Catalyst. Don't use qoutationmarks as they would become part of the path.

Default value: 1

config_file_path

Location of the form config files, used when creating a form with the FormConfig action controller.

Default Value: $c->path_to( 'root', 'forms' )

config_file_ext

Set the default file extension used by the Config() action attribute. This setting is appended to both explicit config filenames, and auto-generated filenames.

Default value: .yml.

default_action_use_name

If set to a true value the action for the form will be set to the currently called action name.

Default value: false.

default_action_use_path

If set to a true value the action for the form will be set to the currently called action path. The action path includes concurrent to action name additioal parameters which were code inside the path.

Default value: false.

Example: action: /foo/bar called uri contains: /foo/bar/1

default_action_use_name => 1 leads to $form->action = /foo/bar

default_action_use_path => 1 leads to $form->action = /foo/bar/1

context_stash

To allow your form validation packages, etc, access to the catalyst context, a weakened reference of the context is copied into the form's stash.

    $form->stash->{context};

This setting allows you to change the key name used in the form stash.

Default value: context

languages_from_context

If you're using a L10N / I18N plugin such as Catalyst::Plugin::I18N which provides a languages method that returns a list of valid languages to use for the currect request - and you want to use formfu's built-in I18N packages, then setting "languages_from_context"

localize_from_context

If you're using a L10N / I18N plugin such as Catalyst::Plugin::I18N which provides it's own localize method, you can set localize_from_context to use that method for formfu's localization.

CAVEATS

When using the Form action attribute to create an empty form, you must call $form->process after populating the form. However, you don't need to pass any arguments to process, as the Catalyst request object will have automatically been set in $form->query.

When using the FormConfig and FormMethod action attributes, if you make any modifications to the form, such as adding or changing it's elements, you must call $form->process before rendering the form.
