推荐答案

您使用的是 Rails 3，它使用 JavaScript 发出删除请求.由于请求设置不正确，您的日志显示 Started POST 而不是正确的 Started DELETE.

You're using Rails 3, which uses JavaScript to issue delete requests. Because the request isn't set up properly, your log is showing Started POST instead of the correct Started DELETE.

请求也不会包含所需的 CSRF 数据，从 Rails 3.0.4 开始，会话被静默重置，而不是抛出 ActionController::InvalidAuthenticityToken 错误.这就是为什么您怀疑身份验证问题出在 Devise 上，但它实际上是在 Rails 内部触发的.

The request will also not include the required CSRF data, and as of Rails 3.0.4 the session is silently reset instead of throwing an ActionController::InvalidAuthenticityToken error. This is why you suspect the authentication issue lies with Devise, but it is actually being triggered within Rails itself.

要解决此问题，请在布局中包含以下内容:

To fix this include the following in your layout:

<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>

还要确保您有更新的 rails.js(其中包含用于删除请求的 JavaScript 代码).Rails 3.0.4 升级说明 更详细地解释问题.

Also ensure you have an updated rails.js (which contains the JavaScript code used for delete requests). The Rails 3.0.4 upgrade notes explain the issue in more detail.

如果您使用 jquery rails.js 替代品，您可以获得更新版本 从这里.

If you're using the jquery rails.js replacement, you can get the updated version from here.
