- What's this?
validate!(context = nil)
public
Runs all the validations within the specified context. Returns true if no errors are found, raises RecordInvalid otherwise.
If the argument is false (default is nil), the context is set to :create if new_record? is true, and to :update if it is not.
Validations with no :on option will run no matter the context. Validations with some :on option will only run in the specified context.
