Rails 功能测试与必需的孩子

发布于 2024-10-16 03:33:50 字数 592 浏览 7 评论 0原文

试图让这个功能测试通过：

test "should create question" do
  assert_difference('Question.count') do
    post :create, :question => @question.attributes
  end
end

但是@question有验证器，要求特定的子项专门出现一个主题：

  class Question < ActiveRecord::Base
    has_many :topic_questions
    has_many :topics, :through => :topic_questions

    validate :has_topic

    def has_topic
      (errors[:base] << "You must have one topic") if (topics.count < 1)
    end
  end

我如何1）在测试中为@question构建主题，然后2）将其传递给post方法，因为它不会被 .attributes() 函数传递吗？

Trying to get this function test to pass:

test "should create question" do
  assert_difference('Question.count') do
    post :create, :question => @question.attributes
  end
end

But @question has validators that require specific children to be present specifically one topic:

  class Question < ActiveRecord::Base
    has_many :topic_questions
    has_many :topics, :through => :topic_questions

    validate :has_topic

    def has_topic
      (errors[:base] << "You must have one topic") if (topics.count < 1)
    end
  end

How would I 1) build the topic for @question in the test and then 2) pass it to the post method since it wouldnt be passed by the .attributes() function?

test "should create question" do
  assert_difference('Question.count') do
    @question.topics<<Topic.new(**set topics required and attribute here )
#or try this line of code 
    @question[:topics]={:name=>"bla bla" ** set attribute here what u need}
    post :create, :question => @question.attributes
  end
end

test "should create question" do
  assert_difference('Question.count') do
    @question.topics<<Topic.new(**set topics required and attribute here )
#or try this line of code 
    @question[:topics]={:name=>"bla bla" ** set attribute here what u need}
    post :create, :question => @question.attributes
  end
end

测试很好，需要更改的是控制器和/或模型。您尚未显示 create 操作的内容，但基本上有两种方法可以实现：

@question = Question.new(params[:question])
@question.build_topic(<some_params>)
if @question.save
  # ... etc ...

或者，在 Question 中使用 accepts_nested_attributes_for :topic code> model，然后在 params 哈希中传递主题参数。哪种方法最好取决于您的具体情况。

The test is fine, it's the controller and/or model that needs changing. You haven't shown the contents of the create action, but there are basically two ways to do it:

@question = Question.new(params[:question])
@question.build_topic(<some_params>)
if @question.save
  # ... etc ...

Or, use accepts_nested_attributes_for :topic in the Question model and then pass the topic parameters in the params hash. Which method is best depends on your specific circumstances.
