I have a form with 3 fields: user_id, email and password. All 3 fields are required, so I have a "validates_presence_of :user_id, :email, :password" in my model.

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. Then the module Ranking has a bunch of instance methods and a submodule ClassMethods. The ClassMethods in this are mixed in to the class with self.included. So far so good. But I want the module to

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.

I''m getting some weird behavior in one of my models. I have a model defined something like this class User < ActiveRecord::Base attr_accessor :password validates_presence_of :password end If I validate the model without specifying a password, I get ["can''t be blank", "can''t be blank"] for :password instead of just one "cant''t

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?
