Question

我目前正在阅读令人敬畏的Rails教程，在我执行git重置以返回之前的提交后，有些东西破坏了我的数据库，突然间我在运行rspec时遇到了5次失败。

Failures:

  1) UsersController Get 'show' should be successfull
     Failure/Error: get :show, :id => @user
     ActionView::Template::Error:
       undefined method `gravatar_for' for #<#<Class:0xaadc884>:0xaad9990>

     ActionView::Template::Error:

     # ./app/views/users/show.html.erb:5:in `_app_views_users_show_html_erb__463664834_89565070__435144589'
     # ./spec/controllers/users_controller_spec.rb:23:in `block (3 levels) in <top (required)>'

     # ./spec/controllers/users_controller_spec.rb:28:in `block (3 levels) in <top (required)>'

  5) UsersController Get 'show' should have a profile image
     Failure/Error: get :show, :id => @user
     ActionView::Template::Error:

     # ./spec/controllers/users_controller_spec.rb:33:in `block (3 levels) in <top (required)>'

我确信这很容易解决，但老实说，我不知道哪里可以看。有人可以帮忙吗？

Answer 1

这是你的问题：

 undefined method `gravatar_for' for #<#<Class:0xaadc884>:0xb9ade94>

您需要确保在个人资料模型中指定了重力数字。

Answer 2

您正在呼叫gravatar_for，这是未知的，第5行：./app/views/users/show.html.erb

即使这已经是答案，请提供详细信息以便我们解决。

我很确定您忘记将该方法添加到User模型中。

Rails教程意外失败/错误：get：show，：id =＆gt; @用户
