What if I don't want the authors in a select field but a text field? Can
I do that?
I have been trying to use something like in

but that example schema set does not have the "|many-to-many ||join|
|table between books & authors"| as in the tutorial.
https://metacpan.org/module/Catalyst::Manual::Tutorial::03_MoreCatalystBasics#CREATE-A-SQLITE-DATABASE
I can't figure out how to write the YAML to get FormFu to put the data
into my edit form while using the many to many join table. Can anyone
help out?
Hi!
I think, this isn't possible via model::dbic.
'To select / deselect rows from a many_to_many relationship, you must
use a multi-valued element, such as a Checkboxgroup or a Select with
multiple set.' -
http://search.cpan.org/~pshangov/HTML-FormFu-Model-DBIC-0.09002/lib/HTML/FormFu/Model/DBIC.pm#many_to_many_selection.
If you need a complex dbic operation, try to manipulate the form
configuration via Catalyst controller. Here is an example (sorry, I
copied form my app, not a general example, don't care about my variables
and object)
In the controller:
sub modify : Chained( 'base' ) : PathPart( 'modify' ) : Args( 0 ) : Form {
my ( $self, $c ) = @_;
...
$c->stash->{form}->load_config_file('picture/modify.conf');
$position = $c->stash->{form}->get_all_element( { type =>
'File', id => 'add' } );
@pictures = $c->model('SqlFS')->list_images( {
container => $c->session->{container},
id => $c->session->{itemId} } );
foreach my $current (@pictures) {
$src = $c->uri_for( '/api/html/geticon/' .
$c->session->{container} . '/' . $c->session->{itemId} . '/' .
$current->name );
$position->parent->insert_before(
$position->parent->element( {
name => $current->name,
type => 'Image',
src => $src,
value => $current->name,
retain_default => 1,
force_default => 0,
}
),
$position
);
}
$c->stash->{form}->process;
...
And the config:
<elements>
type Block
<attributes>
id fieldbox
class fifty
</attributes>
<elements>
type Block
tag label
content_loc form.config.label.picture.modify.fieldset
</elements>
<elements>
type Fieldset
id placeholder
<attributes>
class placeholder
</attributes>
<elements>
<<include ../common/element/file.picture.conf>>
id add
</elements>
</elements>
<elements>
type Fieldset
id buttonholder
<attributes>
class buttonholder
</attributes>
<elements>
<<include ../common/element/submit.back.conf>>
value_loc form.config.value.picture.modify.back
</elements>
<elements>
<<include ../common/element/submit.add.conf>>
value_loc form.config.value.picture.modify.add
</elements>
</elements>
</elements>
