使用设计测试模型保存

Question

我有一个表格，一次最多可以接受 20 个问题。它接收一个数组并将问题保存到数据库中。每个问题都有 4 个答案。我可以很好地将问题保存到数据库中。但是，我遇到了将它们链接到用户的问题。

这里是控制器：

  class QuestionsController < ApplicationController

  def new
    @question_group = []
    20.times do
      @question_group << Question.new
    end
  end

  def create
      params["questions"].each do |question|
        # If the question is empty, we don't want to save it
        if !question_empty?(question) 
          current_user.questions.create!(question_params(question))
        end
      end
    flash[:success] = "Quiz made!"
    redirect_to root_url

  end

它没有通过以下测试：

require 'test_helper'

class CreateQuestionsTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:cookie)
  end


  test "should save the right amount of questions" do 
    post user_session_path, :user => {:email => @user.email, :password =>  @user.password} 
    get new_question_path
    assert_difference 'Question.count', 1 do
      post questions_path, {"questions" => [{"question" => "What is 1+1?",
                           "a1" => "0", "a2" => "1", "a3" => "2", "a4" => "3"}]} 
    end
    assert_difference 'Question.count', 2 do
      post questions_path, { "questions" => [{"question" => "What is 1+1?",
                           "a1" => "0", "a2" => "1", "a3" => "2", "a4" => "3"}, 
                           {"question" => "What is 1 - 1?", "a1" => "1",
                           "a2" => "0", "a3" => "2", "a4" => "3"}]} 
    end
  end 

end

在上面的测试中，问题没有被保存。这适用于手动测试，但我无法为其构建自动化测试。

我建议您对模型设计进行一些更改。而不是处理数组。我会创建一个父对象，如 QuestionForm 接受嵌套表单：

class QuestionForm < ActiveRecord::Base
  has_many :questions, dependent: :destroy
  accepts_nested_attributes_for :questions, reject_if: proc { |attributes| 
   #your reject validations here
 }, allow_destroy: true
end

然后在您的Question 模型中：

class Question < ActiveRecord::Base
  belongs_to :question_form
end

然后您测试QuestionForm 流程（带有嵌套问题）

抱歉，它没有回答您的问题，只是一个提示；）
