Two Rspec before blocks to stub out some behaviour in a controller.First block works, but is verbose. Second block fails, but unsure why. Last chunk of code is the code being tested.Worth noting that changing the method to 'telect' makes it pass

responses_controller_spec.rb

    # This works, but a bit verbose

    before do
      @invitation1, @invitation2 = stub_model(Invitation), stub_model(Invitation)
      stubbed_scope = stub
      Invitation.stub(:accessible_by => stubbed_scope)
      stubbed_scope.stub_chain(:select, :where => [@invitation1, @invitation2])
    end

    # This fails with :
    #     NoMethodError: private method `select' called for #<Object:0x7f5b31904988>

    before do
      @invitation1, @invitation2 = stub_model(Invitation), stub_model(Invitation)
      Invitation.stub_chain(:accessible_by, :select, :where => [@invitation1, @invitation2])
      Response.stub(:create_proxy_responses! => 1)
    end

    # code under test
    
    def find_authorized_invitation_ids
      secured_invitations = Invitation.accessible_by(current_ability, :create_quote).select('invitations.id').where('invitations.id' => params[:selected_invitations])
    end
