Question

我的ApplicationController看起来像这样

class ApplicationController < ActionController::Base  
  before_action :initialize_fields

  protected

  def initialize_fields
    @company_id_super = nil
    @show_company_super = 0
    @round_id_super = nil
    if(params["controller"] == 'companies')
      if(params["id"].present?)
        @company_id_super = params["id"]
      end
    else
      if(params["company_id"].present?)
        @company_id_super = params["company_id"]
      end
    end
    if(@company_id_super != nil)
      @show_company_super = 1
      @company_super = Company.find(@company_id_super)
    else
      @company_super = nil
    end
    if(params["controller"] == 'home' || params[:controller] == 'votes')
      @hide_side_bar = 1
    else
      @hide_side_bar = 0
    end
    if(params["controller"] == 'rounds')
      if(params["id"].present?)
        @round_id_super = params["id"]
      end
    end
  end
end

和我的控制器规格之一看起来像这样

require 'rails_helper'

RSpec.describe OptionsController, type: :controller do
  describe 'Options controller request specs' do
    login_user
    context 'GET #index' do 
      it 'should success and render to index page' do
        contact = create(:option)
        get :index, params: { company_id: 1 }
        assigns(:options).should eq([option])
      end
    end

    context 'GET #show' do
      let!(:option) { create :option }
      it 'should success and render to edit page' do
        get :show, params: { id: option.id, company_id: 1 }
        expect(response).to render_template :edit
      end
    end
  end
end

现在的问题是，当我运行此规范时，出现以下错误：

Failure/Error: @company_super = Company.find(@company_id_super)

ActiveRecord::RecordNotFound:
  Couldn't find Company with 'id'=1
# ./app/controllers/application_controller.rb:36:in `initialize_fields'

现在我知道问题出在应用程序控制器中，但是我不知道如何解决它。我刚刚开始学习测试，有人可以帮助我吗？谢谢！

在发送请求之前，使用Company创建FactoryBot记录。

在您的spec / factories / companies.rb中：

FactoryBot.define do
  factory :company do
    name 'My Company'
    .
    .
  end
end

在您的spec / controllers / options_spec.rb

RSpec.describe OptionsController, type: :controller do

  let(:my_company) { FactoryBot.create(:company) } 

  describe 'Options controller request specs' do
    login_user
      context 'GET #index' do 
        it 'should success and render to index page' do
           contact = create(:option)
           get :index, params: { company_id: my_company.id } #<--- This will create the company record and pass its ID
           assigns(:options).should eq([option])
        end
      end      
    end
  end
end

因此，现在，在您的initialize_fields中，您将在数据库中找到公司记录，并消除了错误。
