Hi Carl,
I can't make it work. The Checkboxgroup is not being populated.
Element/_Group::process is not being called at all.
This is what I have in the config file:
- type: Checkboxgroup
name: area_rel
db:
model: DBIC::Area
label_col: name
constraints: [ AutoSet ]
The rels in DBIC::Campanha model:
__PACKAGE__->has_many(
area_rel => 'SMS::Schema::Result::AreaCampanha', 'campanha_id',
);
__PACKAGE__->many_to_many(areas => 'area_rel', 'area_id',);
# in my app:
$form->defaults_from_model( $campanha_row );
If I change the rel in the config to "name: areas" instead of "name:
area_rel" I got this error:
[error] DBIx::Class::Relationship::ManyToMany::__ANON__(): search_related:
result source 'AreaCampanha' has no such relationship area_id at
/Library/Perl/5.8.6/HTML/FormFu/Model/DBIC.pm line 186
Do you have any idea what am I doing wrong?
Thanks
