Rails multiple conditional validation

Question

I have the following model

class User < ActiveRecord::Base
  VALID_EMAIL_REGEX = /^.+@.+\..+$/i 
  attr_accessible :active_list_id, :password, :password_confirmation, :email, :temp
  has_secure_password
  before_create { generate_token(:auth_token) }
  if :temp.nil?
    before_validation :downcase_email
    validates_presence_of :email, :password, :password_confirmation, :on => :create
    validates_confirmation_of :password
    #[email protected]
    validates :email, :uniqueness => true, 
              :format => {:with => VALID_EMAIL_REGEX }
  end
  after_create { make_list([email,"'s shopping list"].join('')) }

  has_many :shopping_lists
  has_many :transactions, :class_name => 'Order'

  HUMANIZED_ATTRIBUTES = {
    :password_digest => "Password"
  }
  ...
end

I try to create a model in my rails console by calling User.create(:temp => true) (which is a boolean and is defined in my migrations/schema). But it always rollsback the transaction. What am I doing wrong?

I also tried doing :if => temp.nil? and if => "temp.nil?" and :if => lambda { |user| user.temp.nil? } for all 3 of my validations.

turns out has_secure_password auto validates :(

create a method called temp_is_nil? and use that on the if condition

def temp_is_nil?
  temp.nil?
end

make sure that temp is an attribute of user.

before_validation :downcase_email, if: temp_is_nil?
validates_presence_of :email, :password, :password_confirmation, :on => :create, if: temp_is_nil?
validates_confirmation_of :password, if: temp_is_nil?
validates :email, :uniqueness => true, 
          :format => {:with => VALID_EMAIL_REGEX }, if: temp_is_nil?

I figured it out. Turns out I can't skip has_secure_password validations. Here is a ~duplicate question with the solution: stackoverflow.com/questions/10442466/…
