Question

我尝试在我的测试代码中使用reset_session，但它抱怨找不到任何方法。我还尝试使用我在测试中编写的一些身份验证方法，它们也没有产生方法错误（它们在我的application_controller中）

有人可以帮忙解释一下

a）这是所有人都遇到的问题，而不仅仅是我 b）解决方法

***编辑 - 下载一些代码********

来自我的app控制器

class ApplicationController < ActionController::Base
  helper :all # include all helpers, all the time
  protect_from_forgery # See ActionController::RequestForgeryProtection for details
  include SpreedyTools
  # Scrub sensitive parameters from your log
  # filter_parameter_logging :password
  protected

  def logged_in_user?
    @logged_in_user = User.find(session[:user]) if session[:user]
  end

  def logged_in_user=user
    if !user.nil?
      session[:user] = user
      @logged_in_user = user
    end
  end

  def logged_in_user
    if logged_in_user?
      return @logged_in_user
    end
  end

  #checks to see if there is a user logged in, if not redirects to login page.
  def login_required
    unless logged_in_user?
      flash[:error] = "You`ll need login first to access your account. Enter your details and we'll take you where you need to be."
      redirect_to :controller => 'account', :action => 'login'
      return
    end
  end
end

来自我的功能测试

require 'test_helper'
require 'application_controller'

class DashboardControllerTest < ActionController::TestCase
  # Replace this with your real tests.
  setup :login_adam
  fixtures :users

  test "welcome page" do
    get :welcome
    assert_response :success
  end

  test "reset session works in my tests" do
     reset_session 
  end

  test "i can call my methods in application controller" do
    logged_in_user = logged_in_user?
  end

end

运行test：functionals

时出现

和错误

Answer 1

我想我找到了答案：

@request.reset_session

Answer 2

您必须明确定义要在视图/其他控制器中用作辅助方法的方法。所以对于所有那些你必须指定

helper_method :logged_in_user? 
helper_method :login_required

等这将允许您在其他控制器/视图中访问它们

在Rails中为什么我不能在我的测试中使用reset_session或application_controller中的任何方法？
