That looks very nice, but, if you'll permit me an observation, it
only covers the part with the rendering of the two forms.
Would it be possible for you to document the other part of the
usage, too? (I mean the part where you decide which form was
submitted, and then process it). It may seem obvious to you, and I
**think** I can see how it would be done, but having it spelled out
would certainly make it easier for people who are just coming to
catalyst/form-fu.
More like this? this is untested, and written by memory :p someone
might wanna write a test-application based on it?

=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 $c->stash->{form} to store the form, hence you only get the last
form.
One way to work around such problems is to do a little of the work
yourself:
In this example we have a login_form that we want on every page
# root/forms/login.yml:
---
indicator: username
elements:
-
type: Text
name: username
constraints:
- Required
...
We also have an edit-form
# root/forms/foo/edit.yml
---
indicator: name
elements:
-
type: Text
name: name
constraints:
- Required
-
type: Password
name: password
constraints:
- Required
...
We load this in the top-most auto action:
package MyApp::Controller::Root;
use parent 'Catalyst::Controller::HTML::FormFu';
sub auto : Private {
my ($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;
# Since we set indicator, we should only end up here if we
# have a username in the form
$login_form->process();
if ($login_form->submitted_and_valid) {
$c->authenticate({
username => $login_form->field_value('username'),
password => $login_form->field_value('password'),
});
}
}
Any other page that wants to load another form, can now do so freely:
package MyApp::Controller::Foo;
sub edit : Local FormConfig {
my ( $self, $c, $id ) = @_;
my $form = $c->stash->{form};
my $item = $c->model('DBIC::Foo')->find($id);
if ($form->submitted_and_valid) {
# Do whatever you want with it :p
$form->model->update($item);
}
}
In the view-land we now have two stash-variables:
root/foo/edit.tt
[% login_form %]
<h2>edit</h2>
[% form %]
