更新无效属性重新渲染：新模板而不是：编辑

Question

我在控制器中有这个动作：

  def update
    @board = Board.find(params[:board_id])
    @category = Category.find(params[:id])

    if @category.update_attributes(category_params)
      flash[:notice] = "You sucessfully changed category name."
      redirect_to settings_board_path(@board)
    else
      render :edit
    end
  end

此测试用例存在问题：

context "with invalid attributes" do
  let(:updated_category) { FactoryGirl.attributes_for(:category, name: "") }

  it "re-renders :edit template" do
    patch :create, board_id: board, id: category, category: updated_category
    expect(response).to render_template :edit 
  end
end

我收到此错误：

expecting <"edit"> but rendering with <["categories/new", "layouts/application"]>

知道为什么吗？

您的测试正在调用patch :create，而不是patch :update，因此它的操作完全错误。
