show all
Defined in:
lib/torque/postgresql/validations.rb

Overview

Checks if the objects nested into an attribute are valid, adding a single error to the attribute when any of them is not. It takes the regular allow_nil and allow_blank options, which is how values that are merely absent are left out of it

Example:

validates :home, nested: true
validates :settings, nested: true, allow_blank: true
