[html-formfu] Displaying 2 forms in the same page

[Andreas Marienborg]

=head2 Multiple forms using Catalyst::Controller::HTML::FormFu

Sometimes you need to display multiple forms on a single page. If you
try to use FormConfig on several actions in a chain, or similar, they
all use $c->stash->{form} to store the form, hence you only get the last
form.

One way to work around such problems is to do a little of the work  
yourself:

In this example we have a login_form that we want on every page
     root/forms/login.yml:
     ---
         elements:
             -
                 type: Text
                 name: username
     ...

We load this in the top-most auto action:

     package MyApp::Controller::Root;

     use parent 'Catalyst::Controller::HTML::FormFu';

     sub auto : Private {
         my ($self, $c) = @_;

         # We want to utilize alot of the magic that the controller
         # gives us, so therefore we call $self->form like this

         my $login_form = $self->form;
         $login_form->load_config('forms/login.yml');

         # Notice how we put it into another stash var, not 'form'
         $c->stash->{login_form} = $login_form;
     }


Any other page that wants to load another form, can now do so freely:

     package MyApp::Controller::Foo;

     sub edit : Local FormConfig {

     }

Finaly, we need to show both forms:

     root/foo/edit.tt
     [% login_form %]
     <h2>edit</h2>
     [% form %]




Something like that?

If no-one objects, I'll commit it tomorrow
