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
