Rails：切换用户Gem以及切换回原始用户的问题
在我的应用程序中，我使用switch_user （ https://github.com/flyerhzm/switch_user ）gem来允许管理员以另一个用户身份登录。 gem有能力以管理员身份重新登录，但我很难概念化如何做到这一点。
这是我的配置：
SwitchUser.setup do |config| # provider may be :devise, :authlogic, :clearance, :restful_authentication, :sorcery, or :session config.provider = :devise # available_users is a hash, # key is the model name of user (:user, :admin, or any name you use), # value is a block that return the users that can be switched. config.available_users = { :user => lambda { User.all } } # available_users_identifiers is a hash, # keys in this hash should match a key in the available_users hash # value is the name of the identifying column to find by, # defaults to id # this hash is to allow you to specify a different column to # expose for instance a username on a User model instead of id config.available_users_identifiers = { :user => :id } # available_users_names is a hash, # keys in this hash should match a key in the available_users hash # value is the column name which will be displayed in select box config.available_users_names = { :user => :email } # controller_guard is a block, # if it returns true, the request will continue, # else the request will be refused and returns "Permission Denied" # if you switch from "admin" to user, the current_user param is "admin" config.controller_guard = lambda { |current_user, request, original_user| current_user.school_admin? || original_user.school_admin? } # view_guard is a block, # if it returns true, the switch user select box will be shown, # else the select box will not be shown # if you switch from admin to "user", the current_user param is "user" config.view_guard = lambda { |current_user, request, original_user| current_user.school_admin? || original_user.school_admin? } # redirect_path is a block, it returns which page will be redirected # after switching a user. config.redirect_path = lambda { |request, params| '/' } # helper_with_guest is a boolean value, if it set to false # the guest item in the helper won't be shown config.helper_with_guest = true # false = login from one scope to another and you are logged in only in both scopes # true = you are logged only into one scope at a time config.login_exclusive = true # switch_back allows you to switch back to a previously selected user. See # README for more details. config.switch_back = true end
他们的README表示您可以在视图中显示这些链接
但是没有办法加载“原始用户”来检查你是否需要显示管理员登录链接..其他人有使用这个gem的经验吗？
我有切换用户及其切换选项的类似问题，所以最后我试图自己实现一些东西。
我用它作为起点，我希望它对你也有帮助。
您可以通过执行操作从控制器访问原始用户
provider = SwitchUser::Provider.init(self) provider.original_user
