NAME
       HTML::FormFu::Constraint::DBIC::Unique -	unique constraint for
       HTML::FormFu::Model::DBIC

VERSION
       version 2.03

SYNOPSIS
	   $form->stash->{schema} = $dbic_schema; # DBIC schema

	   $form->element('text')
		->name('email')
		->constraint('DBIC::Unique')
		->resultset('User')
		;

	   $form->stash->{context} = $c; # Catalyst context

	   $form->element('text')
		->name('email')
		->constraint('DBIC::Unique')
		->model('DBIC::User')
		;

	   $form->element('text')
		->name('user')
		->constraint('DBIC::Unique')
		->model('DBIC')
		->resultset('User')
		;

	   or in a config file:
	   ---
	   elements:
	     - type: text
	       name: email
	       constraints:
		 - Required
		 - type: DBIC::Unique
		   model: DBIC::User
	     - type: text
	       name: user
	       constraints:
		 - Required
		 - type: DBIC::Unique
		   model: DBIC::User
		   column: username

DESCRIPTION
       Checks if the input value exists	in a DBIC ResultSet.

METHODS
   model
       Arguments: $string # a Catalyst model name like 'DBIC::User'

   resultset
       Arguments: $string # a DBIC resultset name like 'User'

   self_stash_key
       reference to a key in the form stash. if	this key exists, the
       constraint will check if	the id matches the one of this element,	so
       that you	can use	your own name.

   id_field
       Use this	key to define reference	field which consist of primary key of
       resultset. If the field exists (and $self_stash_key not defined), the
       constraint will check if	the id matches the primary key of row object:

	   ---
	   elements:
	     - type:  Hidden
	       name:  id
	       constraints:
		 - Required

	     - type:  Text
	       name:  value
	       label: Value
	       constraints:
		 - Required
		 - type:       DBIC::Unique
		   resultset:  ControlledVocab
		   id_field:   id

   others
       Use this	key to manage unique compound database keys which consist of
       more than one column. For example, if a database	key consists of
       'category' and 'value', use a config file such as this:

	   ---
	   elements:
	     - type:  Text
	       name:  category
	       label: Category
	       constraints:
		 - Required

	     - type:  Text
	       name:  value
	       label: Value
	       constraints:
		 - Required
		 - type:       DBIC::Unique
		   resultset:  ControlledVocab
		   others:     category

   method_name
       Name of a method	which will be called on	the resultset. The method is
       passed two argument; the	value of the field, and	the primary key	value
       (usually	`id`) of the record in the form	stash (as defined by
       self_stash_key).	An example config might	be:

	   ---
	   elements:
	     - type: text
	       name: user
	       constraints:
		 - Required
		 - type: DBIC::Unique
		   model: DBIC::User
		   method_name:	is_username_available
