Instance Method Details

#valid_with_recursion_control?(*args, &block) ⇒ Boolean

It’s easy to break out of circular validation dependencies. All we need to do is suppose that if a record’s validity depends in some way on itself, then we can assume that circular condition is satisfied. That assumption will change nothing about the actual validity of the record.

Returns:

• (Boolean)

def valid_with_recursion_control?(*args, &block)
  assumed_valid? or with_recursion_control do valid_without_recursion_control?(*args, &block) end
