Rails custom validation one after another

I have a password field and that validates presence and length and both are working fine. But when I submit the form with blank password field, it displays error messages for both validations.

What I want is if the password is blank then length validator must not checked and display error message for only presence validator. Length validator will only be checked if password is present.

Solution

  • Along with other validations pass this 

    :allow_blank => true

    For example

    validates :password, :presence => true, :length => { :maximum => 20, :allow_blank => true }
