This post has got to be a bit of a long running soap opera... sorry -
I am trying to keep the items within it focused...
I am attempting to produce some relatively complex forms within a
catalyst application (Catalyst, DBIx::Class, HTML::FormFu etc
are all current CPAN versions running on a recently built 5.12.3
perl).
The form involves a set of cross db table sets that I cannot directly
model with DBIC/FormFu, so I decided to try using a
HTML::FormFu::Model::HashRef model - transforming the dataset into/from
a hashref from/to the db.
Problem 1:
Populating the options into a set of Selects (would have been done
in a DBIC model_config if it was a straight DBIC/FormFu combination).
There just isn't a straight analogue of this using the HashRef model.
However, I do have for other purposes, a FormFu plugin that populates
Selection options from the form stash. That works fine normally...
but in this configuration would not work, unless I removed the FormConfig
attribute from the catalyst controller and manually got the form object,
loaded the config file etc, then ensured the form stash was loaded, then
did $form->process. Just adding additional $form->process state to the
normal controller did not have that effect
So
Problem 2:
FormFu is saving internal state that is not updated by a $form->process
stage. You need to defer process until all setup has been done, which
breaks some of the Catalyst::Controller::HTML::FormFu workflow
Strangely using ::Model::DBIC seems to cause some internal state to
be updated, and doing the same operations then works!
Theres a number of other hacks I tried (pasting additional fields into
a part built form to add a variable number of select fields), which
discovered that the insert_after/insert_before methods also suffer from
state being saved within the form and only work on a flat form.
I was going to build a more formal set of bug reports against the current
dev version on github, but I can't make that build properly.
Actually a further look shows that its just spewing warnings on t/01use.t
but those distract from the fact that the tests pass. I'll see if I get
the same effects on the github version...
