railstutorial.org“设置”链接断开

Question

我正在研究 Michael Hartl 的 railstutorial。我的问题是 /user/1/edit 呈现完美，但使用 edit_user_path(current_user) 没有。

我检查了拼写错误，进行了一些搜索，found this 似乎是同一个问题，但答案没有让我的链接正常工作。现在，我正在尝试用Michael's 来区分我的代码。

如果有任何其他代码可以提供帮助，请告诉我。 感谢您花时间阅读我的问题。

Answer 1

这个：

<%= link_to "Settings", 'edit_user_path(current_user)' %>

应该变成这样：

<%= link_to "Settings", edit_user_path(current_user) %>

您的日志显示应用程序会查找 /edit_user_path(current_user)，因为您将其作为字符串发送，并且通常您没有此路径。查看日志的第一行Started GET "/edit_user_path(current_user)"

应该是Started GET "/users/1/edit"
