Devise在登录或注册后重定向到原始位置？ [英] Devise redirect back to the original location after sign in or sign up?

问题描述

这里我使用Devise Gem进行身份验证。如果有人想要打开页面而不登录，那么它会重定向到sign_in页面，并在登录后返回到用户尝试打开的页面。
我使用重定向循环与Devise after_sign_in_path_for 链接为我的问题，但它不适用于我。

Here I'm using Devise Gem for authentication. If someone want to open page without login then it redirect to sign_in page and after signed in it back to the page which user try to open. I use Redirect loop with Devise after_sign_in_path_for link for my problem but it does not work for me.

 def after_sign_in_path_for(resource)
   params[:next] || super 
 end

它不会将我重定向到我要打开的页面。
例如：如果我要打开127.0.0.1:3000/post/2/edit，它登录后不会返回此页面。

It doesn't redirect back me to the page which I want to open. for example: If I want to open "127.0.0.1:3000/post/2/edit", it doest not back to this page after signed in.

推荐答案

最好的资源是官方回购/维基/问题，然后是SO。你发现的答案已经过时了。

The best resource to seek is the official repo/wiki/issues, and then SO. The answer you found is out of date.

这是答案：
https://github.com/ plataformatec / devise / wiki / How-To：-Redirect-back-to-current-page-after-sign-in，-sign-out，-sign-up，-update

在ApplicationController中添加以下内容

Just add the following in ApplicationController

after_filter :store_location

def store_location
  # store last url as long as it isn't a /users path
  session[:previous_url] = request.fullpath unless request.fullpath =~ /\/users/
end

def after_sign_in_path_for(resource)
  session[:previous_url] || root_path
end
