- What's this?
clear_validators!()
public
Clears all of the validators and validations.
Note that this will clear anything that is being used to validate the model for both the validates_with and validate methods. It clears the validators that are created with an invocation of validates_with and the callbacks that are set by an invocation of validate.
class Person include ActiveModel::Validations validates_with MyValidator validates_with OtherValidator, on: :create validates_with StrictValidator, strict: true validate :cannot_be_robot def cannot_be_robot errors.add(:base, 'A person cannot be a robot') if person_is_robot end end Person.validators # => [ # #<MyValidator:0x007fbff403e808 @options={}>, # #<OtherValidator:0x007fbff403d930 @options={on: :create}>, # #<StrictValidator:0x007fbff3204a30 @options={strict:true}> # ]
If one runs Person.clear_validators! and then checks to see what validators this class has, you would obtain:
Person.validators # => []
Also, the callback set by validate :cannot_be_robot will be erased so that:
Person._validate_callbacks.empty? # => true
