Defined in:
lib/tram/validators/validity_validator.rb

Overview

Checks that value of some attribute is valid per se Otherwise populates the record with the attribute’s validation errors

With option ‘original_keys: true` it copies value’s errors to the record under their original keys, as if the [#record] had attributes of the [#value]. Otherwise the errors are copied under the [#attribute] key.

This is necessary for validation of the form models, as well as other decorated objects.

Examples:

Checks that user.valid? returns true

validates :user, validity: { nested_keys: true }
