Question

我是Michael Hartl教程之后的新手程序员。

我即将完成第9章，它增加了查看网站上所有用户的功能，并删除了具有管理功能的个人。

所有规格都在传递，一切都按预期在本地运行。但是，当我在Heroku测试该站点时，用户的索引看起来与本地索引不同。

我尝试在推送到Heroku之前预先编译资产，这已经解决了问题。但是，现在删除用户的功能不起作用。我没有删除用户，而是转发给该用户。本地版本也是如此。此外，我注意到单击注销链接返回错误：

No route matches [GET] "/signout"

我的所有规格仍在传递，这对我来说只是一个谜！我怀疑这是资产如何编译的问题，但作为一个铁杆新手，感觉就像在大海捞针寻找，所以任何帮助都是受欢迎的。

Answer 1

此问题No route matches [GET] "/signout"是相关的，因为您实际上不接受GET上的/signout请求，您的路由定义应该是DELETE动词。

这可能是因为缺少javascript库，你能检查一下是否丢失了吗？

Answer 2

使用此application.js文件并尝试

<强>的application.js

//= require jquery
//= require jquery_ujs
//= require_tree .

在您正在阅读的图书中，请参阅Listing 8.25.

Answer 3

在评论者和外人的帮助下，我设法解决了这个问题。

首先，我删除了public/assets文件夹，这使得Heroku可以进行编译。

然后我将//= require bootstrap移到我的jquery导入下面：

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require_tree .

本地预编译资产破坏了我的应用程序
