ruby-on-rails - 无法在 Rails 测试中创建用户和登录

问题描述

我正在处理我的 Rails 应用程序的测试，并注意到在添加登录功能后我的一些测试失败了，因为视图使用会话变量中的当前 user_id，该变量在测试期间未定义。

我试图通过创建一个发布请求来创建一个用户（用户可以是我的应用程序的教授或学生）然后在测试中使用该用户登录来解决这个问题：

course_controller_test.rb

setup do
    @course = courses(:one)
    @user = professors(:admin)
end

test "should get new" do

  professor_http_code = post professors_path, params:  {professor: {firstname:@user.firstname,
                                                     lastname: @user.lastname,
                                                     email: @user.email,
                                                     password: "123456",
                                                     password_confirmation: "123456"}}

  puts "Professor post http code: " + professor_http_code.to_s
  login_http_code = post login_path, params: {email: @user.email,
                                           password: "123456",
                                           type: {field: "professor"}}
  puts "Login post http code: " + login_http_code.to_s
  get new_course_url
  assert_response :success
end

测试失败并出现同样的问题（呈现视图时没有当前用户）并在控制台中产生以下输出：

控制台输出

Expected response to be a <2XX: success>, but was a <500: Internal Server Error>

这是我的会话和教授控制器功能，它们正在处理请求：

教授控制器

class ProfessorsController < ApplicationController
...

  def create
    @professor = Professor.new(professor_params)
    puts "Professor create params: " + params[:professor].inspect
    respond_to do |format|
      if @professor.save
        puts "password_d: " + @professor.password_digest
        log_in(@professor, "professor")
        format.html { redirect_to @professor, notice: 'Professor was successfully created.' }
        format.json { render :show, status: :created, location: @professor }
      else
        puts "Professor not saved to db"
        format.html { render :new }
        format.json { render json: @professor.errors, status: :unprocessable_entity }
      end
    end
  end
...

    # Never trust parameters from the scary internet, only allow the white list through.
    def professor_params
      params.require(:professor).permit(:firstname, :lastname, :email, :password, :password_confirmation)
    end

会话控制器

class SessionsController < ApplicationController

...
def create
    user = nil
    type = params[:type][:field]
    if type == "student"
      user = Student.find_by_email(params[:email])
    elsif type == "professor"
      user = Professor.find_by_email(params[:email])
    end
    puts "user login params: " + user.inspect
    if user && user.authenticate(params[:password])
      puts "logging in"
      log_in(user, type)
      redirect_to root_url, notice: "Logged in!"
    else
      puts "invalid password"
      flash.now[:alert] = "Email or password is invalid"
      render "new"
    end
  end

...

控制台输出显示教授没有保存到数据库中，但在应用程序上创建教授帐户工作正常，而且当我在测试环境中的 rails 控制台中键入以下内容时，它工作正常：

app.post "/professors", params: {professor: {firstname: "foo", lastname: "bar", email: "foobar@gmail.com", password: "123456", password_confirmation: "123456"}}

我尝试向参数添加随机的authentity_token，对参数中的所有字符串进行硬编码而不是使用@user 对象，然后删除并重新创建、迁移、加载和准备我的测试数据库，但都没有运气。

如果您需要在我的应用程序中查看其他内容来解决问题，请告诉我，任何帮助将不胜感激！
