Rails + Devise：如何覆盖before_filter“authenticate_user！”的重定向

我在Rails 3和最新版本的Devise上，我在AdminController有一个beforefilter来authenticate_user! 我需要在重定向之前为request.referrer存储一个会话变量，以便我可以在尝试继续时将其发送回/ admin页面。 我会在哪里覆盖authenticate_user! ？

我想做的是这个，但我不知道在哪里定义它：

 def authenticate_user! session[:return_to] = request.request_uri super end 

Answer 1

你实际上并不需要这样做，设计将尊重after_sign_in_path用于这个目的。

在您的应用程序控制器

 before_filter :set_return_path def after_sign_in_path_for(resource) session["user_return_to"] || root_url end def set_return_path unless devise_controller? || request.xhr? || !request.get? session["user_return_to"] = request.url end end 

从设计助手：

 # The default url to be used after signing in. This is used by all Devise # controllers and you can overwrite it in your ApplicationController to # provide a custom hook for a custom resource. # def after_sign_in_path_for(resource_or_scope)

替代Matt的答案，它不需要在每个页面视图上记录返回页面：

在application_controller.rb中：

 # Only remembers the page immediately before we # redirect them for auth, instead of every page view def authenticate_user! session["user_return_to"] = request.fullpath super end # Deletes the return path as soon as it's used, so # they aren't accidentally redirected back again # next time they login def after_sign_in_path_for(resource) session.delete("user_return_to") || root_path end
