[html-formfu] How to make checkbox (checked/unchecked) database driven

[kewei xiao]

Thank you for these hints.  But inn my customized element, I used multi 
instead of checkbox, below is my code:

use strict;
use warnings;

use base qw( HTML::FormFu::Element::multi );

__PACKAGE__->mk_accessors(qw( group_type ));

sub render {
  my $self = shift;
  my $type = $self->group_type;

  $self->attributes( { class => $type . 'group' } );
  my $c = $self->form->stash->{ context };
  my $roles = $c->model( 'Links::AccountRole' )->search;
  $self->elements( [ map {
      { type => $type, name=>'role', value=> $_->id, label => $_->name, 
id=>'role_'.$_->id, /*'checked'(maybe a condition here)*/ }
  } $roles->all ] );

   return $self->SUPER::render( @_ );
}

In my app, I have a 'update' which I can get the details of each user in 
database.  Each user has a checkbox to indicate whether he is 
administrator.  If he is, the checkbox will be checked, otherwise the 
checkbox is unchecked.  Right now every checkbox is checked, even the 
user is not an administrator.  That's the part I am struggling with.
