HTML::FormFu::Constraint::Unique
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.
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
