Rails3 + Devise : prevent password validation when updating

Question

I\'ve looking for a way to allow users to change their settings (User model) without having to change their password (they still have to enter their current password). Devis

I tried Amal Kumar S solution, but unfortunately it didn't help me to solve the same issue, so here is modified version of solution tested in real project.

Here is the code from devise/models/validatable.rb module

protected

# Checks whether a password is needed or not. For validations only.
# Passwords are always required if it's a new record, or if the password
# or confirmation are being set somewhere.
def password_required?
  !persisted? || !password.nil? || !password_confirmation.nil?
end

The validation fails when you leave blank password and password confirmation fields while updating user info, because this condition is always false:

!password.nil? || !password_confirmation.nil? 

Password and password_confirmation fields equals blank string '' which is never equals to nil. So you can fix that by overriding password_required? method in your user model and change nil? check to blank? check.

protected

def password_required?
 !persisted? || !password.blank? || !password_confirmation.blank?
end

Think that it's easiest way to fix that and it's doesn't ruin original logic. Maybe it's devise's bug.
