Michael Hartl的Ruby on Rails教程:第8.3章-网站表单显示两次
Michael Hartl的Ruby on Rails教程:第8.3章-网站表单显示两次
提问于 2012-04-06 07:59:05
我目前正在学习Ruby on Rails教程，在完成教程中的section 8.3之后遇到了一个小问题。在功能上，一切都很好，我可以通过我的表单和一切添加用户。然而，现在我的表单在网站的每个页面上都显示了两次。我已经多次检查了代码，就是找不出是什么导致了这种情况的发生。这是我的Heroku网站的链接，你可以在那里看到这个问题：http://deep-mist-5284.heroku.com/
当我在rails服务器中运行网站时，它会输出它正在使用的这些文件，但我已经查看了这些文件，没有发现任何错误。

在您的<%= /application.html.erb中有两个%> your布局。您让Rails将users/new.html.erb (以及每隔一个页面)的内容放入您的布局/application.html.erb中两次。删除其中一个，所有的都将被修复。
