I''ve implemented Rails Recipe #31, Authentication, and I found that validating password and password_confirmation just doesn’t work while the method ‘password=(pass)’ is in the mix, but I need that for the salt/hashing, no? If I don’t use validations, the password gets hashed, salted and stored in the database fine. I can login with same username/password. However, if I want to

Is there a way to specify the order in which the validations (and corresponding error messages) should

Re: rails question
Hi Shelby, No prob, You are having trouble b/c you don''t call @festival.valid? before this line: if !(@festival.errors.invalid? :name ) # => true if name is invalid I wasn''t clear about it in my post, but ActiveRecord::Errors#invalid? doesn''t actually do validations.

Anyone got any idea of how to use built-in validation methods in a mixed-in module. What I''ve got at the moment is each class that needs ranking methods includes [the module] Ranking.

boolean db fields set to false fail validation with validates_presence_of?
I have a model that contains a :boolean field. In my view, I have a simple select of Yes or No, which equates to true or false, respectively. If I choose yes and save, everything works great. If I choose no, my model fails validation as I have this set as a required field using validates_presence_of. I have checked the log and it''s definitely set to false, why would this fail validation?
