使用devise測試模型保存

Question

我有一個表格，一次最多可以接受20個問題。 它接收一個數組並將問題保存到數據庫中。 每個問題有4個答案。 我可以將問題保存到數據庫中。 但是，我遇到了將它們鏈接到用戶的問題。

這是控制器：

  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

它無法通過以下測試：

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

在上面的測試中，問題未保存。 這適用於手動測試，但是我無法為此建立自動測試。

我建議您對模型設計進行一些更改。 而不是處理數組。 我將創建一個像QuestionForm這樣的父對象來接受嵌套表單：

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

然后您測試QuestionForm流（帶有嵌套問題）
