Nested Attribtues and attribtues_for

[Keenan Brock]

Hi All,

I realize I have a similar question to Gordon.

When I have an association in a factory, attributes_for does not provide a value for that association. So I can not use it out of the box.

My hack has been to merge a previously created model, which adds the association attributes. (i.e: zombie_type and zombie_color)

Can you suggest an alternate way to solve this problem?

Due to uniqueness constraints, I can not use pass @zombie.attributes.

Thanks,

Keenan

class Zombie < ActiveRecord::Base

  belongs_to :zombie_type

  belongs_to :zombie_color

  

  validates :image, :zombie_type, :color_name, :presence => true

  validates :name, :presence => true, :uniqueness => true

  #snip

end

FactoryGirl.define do

  factory :zombie do

    sequence(:name) { |n| "zombie_#{n}"}

    image 'image.jpg'

    association :zombie_type

    association :zombie_color

  end

end

class ZombiesControllerTest < ActionController::TestCase

  setup do

    @zombie = FactoryGirl.create(:zombie)

  end

  #snip

  test "should create zombie" do

    assert_difference('Zombie.count') do

      post :create, zombie: attributes_with_associations

      assert assigns(:zombie).valid?, assigns(:zombie).errors.full_messages.join(", ")

      assert_match /success/, notice

    end

    assert_redirected_to zombies_path

  end

  #snip

  private

  # LOOK HERE

  def attributes_with_associations

    @zombie.attributes.merge(FactoryGirl.attributes_for(:zombie))

  end

  #/LOOK HERE

  def notice

    flash[:notice]

  end

end
