Question

在routes.rb我有：

resources :themes do
  resources :messages
end

在messages_controller_test.rb我有：

  setup do
    @theme = themes(:one)
    @message = messages(:one)
  end

  test "should create message" do
    assert_difference('Message.count') do
        post :create, message: { title: "Title", body: "Some body", theme_id: @theme.id }
    end

    assert_redirected_to theme_path(@theme)
  end

我收到错误：Couldn't find Theme without an ID

出了什么问题？

Answer 1

使用嵌套资源，创建路径如下所示：

/themes/:theme_id/messages

所以你需要传递这些参数：

test "should create message" do
  assert_difference('Message.count') do
      post :create, {theme_id: @theme.id, message: { title: "Title", body: "Some body", theme_id: @theme.id }}
  end

  assert_redirected_to theme_path(@theme)
end

实际上在你的控制器动作中你可以处理：theme_id param以便不再在params中传递它[：message]

嵌套控制器动作测试
