That certainly makes it clearer. (And I'm amazed that I missed the
"indicator" entry while reading the form-fu documentation). Just one
quibble: Shouldn't the comment
# Since we set indicator, we should only end up here if we
# have a username in the form
come AFTER this if?
if ($login_form->submitted_and_valid) {
Or am I completely misunderstanding how and where indicator is used?

=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 %]
