In my app I am using the switch_user (https://github.com/flyerhzm/switch_user) gem to allow admins to login as another user. The gem has the ability to log back in as an admin, but I am having a hard time conceptualizing how to do it.
Here is my config:
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
Their README says you can have these links in your view
<%= link_to user.login, "/switch_user?scope_identifier=user_#{user.id}" %>
<%= link_to admin.login, "/switch_user?scope_identifier=admin_#{admin.id}" %>
But there is no way to load the "original user" to check to see if you need to display the admin login link.. anyone else have experience using this gem?
I had similar issues with switch user and its switching back option, so at the end I am trying to implement something by myself.
I'm using this as a starting point, I hope it helps you as well.
