Unit testing errors when using :delegate without :prefix on 3.0.x

[jan0sch]

Hi,

I'm running into an issue using the delegate method on rails 3.0.9 without the prefix option.
Here are my two models:

    class User < ActiveRecord::Base
      acts_as_authentic

      has_one :user_condition

      validates_presence_of :username
      validates_presence_of :password, :if => :new_record?
      validates_presence_of :password_confirmation, :if => :new_record?

      delegate  :height,
                :weight,
                :resting_heart_rate,
                :blood_pressure_systolic,
                :blood_pressure_diastolic,
                :abdominal_girth,
                :to => :user_condition
    end

    class UserCondition < ActiveRecord::Base
      attr_accessible :user_id, :user, :height, :weight, :resting_heart_rate, :blood_pressure_systolic, :blood_pressure_diastolic, :abdominal_girth

      belongs_to :user

      validates_presence_of :user
      validates_uniqueness_of :user
      validates_numericality_of :height, :weight, :resting_heart_rate, :blood_pressure_systolic, :blood_pressure_diastolic ,:abdominal_girth
    end

This works as expected within the application. Meaning if I use @user.height in my view it works.
However if I do run the following unit test it fails:

    class UserConditionTest < ActiveSupport::TestCase
      def test_should_be_valid
        attributes = {}
        attributes[:user] = User.first
        attributes[:height] = 0
        attributes[:weight] = 0
        attributes[:blood_pressure_systolic] = 0
        attributes[:blood_pressure_diastolic] = 0
        attributes[:resting_heart_rate] = 0
        attributes[:abdominal_girth] = 0
        assert UserCondition.new(attributes).valid?
      end
    end

If I add the option

    :prefix => true

to the :delegate call the unit test runs fine. Although I have to change my views.

I tried to workaround the problem using something like

    delegate :height, :to => "self.try(:user_condition) or return ''"

but that did not help regarding the unit test. :-(

I just saw that the problem is probably not related to delegate as running "rake test" instead of "rake test:recent" also fails even if I use the prefix option. Closing this for now. I'll dig into with a little more time on my hands.
