    <p>I'm seeing some strange behavior when I'm trying to stub out some methods. I'm using rails 3.0.3 and rspec 2.3.0</p> <p>Here is the relevant section of the spec file</p> <pre><code> require 'spec_helper' include Authlogic::TestCase describe PrizesController do before do activate_authlogic @manager = Factory.create(:valid_manager, :name =&gt; "Test Manager ") UserSession.create @manager end def mock_prize(stubs={}) (@mock_prize ||= mock_model(Prize, :point_cost =&gt; 100).as_null_object).tap do |prize| prize.stub(stubs) unless stubs.empty? end end def mock_consumable(stubs={}) (@mock_consumable ||= mock_model(Consumable).as_null_object).tap do |consumable| consumable.stub(stubs) unless stubs.empty? end end describe "GET buy_this" do it "assigns the requested prize as @prize and requested consumable as @consumable if the player has enough points" do Prize.stub(:find).with("37") { mock_prize } @manager.should_receive(:available_points).and_return(1000) get :buy_this, :id =&gt; "37", :user_id =&gt; @manager.id assigns(:prize).point_cost.should eq(100) assigns(:prize).should be(mock_prize) assigns(:consumable).should_not be_nil end it "assigns the requested prize as @prize and no consumable as @consumable if the player does not have enough points" do Prize.stub(:find).with("37") { mock_prize } @manager.should_receive(:available_points).and_return(10) get :buy_this, :id =&gt; "37", :user_id =&gt; @manager.id assigns(:prize).point_cost.should eq(100) assigns(:prize).should be(mock_prize) assigns(:consumable).should be_nil end end </code></pre> <p>And the controller method:</p> <pre><code> def buy_this @prize = Prize.find(params[:id]) user = User.find(params[:user_id]) if params[:user_id] user ||= current_user flash[:notice] = ("Attempting to redeem points for a prize") if user.available_points &gt; @prize.point_cost @consumable = user.consumables.create(:kind =&gt; @prize.consumable_kind, :description =&gt; @prize.consumable_description, :redemption_message =&gt; @prize.consumable_redemption_message) point_record = @consumable.create_point_record(:redeemed_points =&gt; @prize.point_cost) point_record.user = user point_record.save flash[:success] = "You successfully redeemed #{@prize.point_cost} points for #{@prize.name}" else flash[:error] = "Sorry, you don't seem to have enough points to buy this" end redirect_to prizes_path end </code></pre> <p>The tests fail and this is the output...</p> <pre><code> 1) PrizesController GET buy_this assigns the requested prize as @prize and requested consumable as @consumable if the player has enough points Failure/Error: assigns(:consumable).should_not be_nil expected not nil, got nil # ./spec/controllers/prizes_controller_spec.rb:39 2) PrizesController GET buy_this assigns the requested prize as @prize and no consumable as @consumable if the player does not have enough points Failure/Error: @manager.should_receive(:available_points).and_return(10) (#&lt;User:0x10706b000&gt;).available_points(any args) expected: 1 time received: 0 times # ./spec/controllers/prizes_controller_spec.rb:44 </code></pre> <p>Any ideas about this? I'm totally stumped why the two tests calling the same method with the same parameters would fail in different ways (not to mention, I don't understand why they are failing at all...).</p>

    3. CO1) Looks like `@consumable` isn't being assigned properly. Either you have validations preventing it from being saved, or it is never getting into that `if` block. Which is most likely caused by your `available_points` method never being called on the stubbed object...which is odd. +1

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
