只要单击模型销毁链接，Rails 会话就会被销毁

Question

如果我在 3 个模型的任何记录上单击“销毁”，用户将被注销。我正在使用 Devise 和 Ominauth。

#This logs out a user 
def destroy
    @rating = Rating.find(params[:id])
    @rating.destroy
  end


Started POST "/ratings/29" for 192.168.1.103 at 2011-02-26 20:11:45 +0000
  Processing by RatingsController#destroy as HTML
  Parameters: {"id"=>"29"}
  User Load (0.5ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 2 LIMIT 1

  SQL (0.0ms)  BEGIN

Answer 1

您正在使用 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。

该请求也不会包含所需的 CSRF 数据，并且从 Rails 3.0.4 开始，会话会静默重置，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，但实际上它是在 Rails 本身内部触发的。

要解决此问题，请在布局中包含以下内容：

<%= 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 更详细地解释这个问题。

如果您使用 jquery Rails.js 替代品，则可以获得更新版本 从这里。
