G'day folk,
I've been working through the Catalyst tutorial (again) and I decided to
give HTML::FormHandler a go. It's tutorial at
https://metacpan.org/module/GSHANK/HTML-FormHandler-0.40017/lib/HTML/FormHandler/Manual/Tutorial.pod
has been great.
However I am stuck on something I am certain should be easy, but is not
proving so...
As per the tutorial my edit method looks much like this:
sub edit : Local {
my ( $self, $c, $book_id ) = @_;
$c->stash( template => 'books/edit.tt2',
form => $self->form );
# Validate and insert/update database
return unless $self->form->process( item_id => $book_id,
params => $c->req->parameters,
schema => $c->model('DB')->schema );
# Form validated, return to the books list
$c->flash->{status_msg} = 'Book saved';
$c->res->redirect($c->uri_for('list'));
}
and that works beautifully. However, I've enhanced my examples as I've
gone along and instead of going to the list of books, I want to go to my
review page and print out all of the details (including extra stuff) of
this specific book I've just added.
So I would like to change the last line to be:
$c->res->redirect($c->uri_for($self->action_for('review'), [$book_id]));
This works perfectly if I'm editing a book, but if I'm creating a book
for the first time, $book_id is undefined so I pass in an undefined id
to review. Review seems to deal with that okay:
sub review :Chained('object') :PathPart('review') :Args(0) {
my ($self, $c) = @_;
my $book = $c->stash->{object};
...
until I want to use $book for something.
I have looked through most of the documentation for HTML::FormHandler
and I can't find anything that actually documents process() (it returns
1 on success) and I don't know the Catalyst stash well enough. Is this
information hiding therein or do I need to create a method to get the
last insert id?
All help gratefully appreciated.
Jacinta
