Ruby on rails Rails测试错误，NameError:uninitialized constant User:：FILL\u IN

我目前正在学习RubyonRails教程

我做了rails测试，然后得到了这个错误

错误日志 app/controllers/account\u activations\u controller.rb

class AccountActivationsController

测试/集成/用户注册测试.rb

需要“测试助手”
类UsersSignupTest

你能帮我解决这个问题吗？

你不应该实际使用

FILL\u这个词。您应该更改
填写
以使测试通过。您可能需要以下内容：

update_columns(activated: true, activated_at: Time.now)

您不应该实际使用
FILL\u IN
。您应该更改

update_columns(activated: true, activated_at: Time.now)

class AccountActivationsController < ApplicationController

  def edit
    user = User.find_by(email: params[:email])
    if user && !user.activated? && user.authenticated?(:activation, params[:id])
      user.activate
      log_in user
      flash[:success] = "Account activated!"
      redirect_to user
    else
      flash[:danger] = "Invalid activation link"
      redirect_to root_url
