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

the constraint will check if the id matches the primary key of row object:

elements:
- type: text
