我们在主动管理成功登录时遇到问题，问题是在成功登录后，主动管理员重定向到用户登录页面，即http://localhost:3000/users/sign_in。它工作得很好，但突然之间可能是活动管理员的新更新导致了这个问题，因为我们在其他项目中也有活跃的管理员工作正常，直到我们用bundle更新gems并且行为也发生了变化。有什么建议吗？ 这是我的配置文件
ActiveAdmin.setup do |config|
# == Site Title
#
# Set the title that is displayed on the main layout
# for each of the active admin pages.
#
config.site_title = ENV['app_name']
# Set the link url for the title. For example, to take
# users to your main site. Defaults to no link.
#
# config.site_title_link = "/"
# Set an optional image to be displayed for the header
# instead of a string (overrides :site_title)
#
# Note: Aim for an image that's 21px high so it fits in the header.
#
config.before_filter :set_admin_timezone
config.site_title_image = "admin-logo.png"
# == Default Namespace
#
# Set the default namespace each administration resource
# will be added to.
#
# eg:
# config.default_namespace = :hello_world
#
# This will create resources in the HelloWorld module and
# will namespace routes to /hello_world/*
#
# To set no namespace by default, use:
# config.default_namespace = false
#
# Default:
# config.default_namespace = :admin
#
# You can customize the settings for each namespace by using
# a namespace block. For example, to change the site title
# within a namespace:
#
# config.namespace :admin do |admin|
# admin.site_title = "Custom Admin Title"
# end
#
# This will ONLY change the title for the admin section. Other
# namespaces will continue to use the main "site_title" configuration.
# == User Authentication
#
# Active Admin will automatically call an authentication
# method in a before filter of all controller actions to
# ensure that there is a currently logged in admin user.
#
# This setting changes the method which Active Admin calls
# within the application controller.
config.authentication_method = :authenticate_admin_user!
# == User Authorization
#
# Active Admin will automatically call an authorization
# method in a before filter of all controller actions to
# ensure that there is a user with proper rights. You can use
# CanCanAdapter or make your own. Please refer to documentation.
# config.authorization_adapter = ActiveAdmin::CanCanAdapter
# In case you prefer Pundit over other solutions you can here pass
# the name of default policy class. This policy will be used in every
# case when Pundit is unable to find suitable policy.
# config.pundit_default_policy = "MyDefaultPunditPolicy"
# You can customize your CanCan Ability class name here.
# config.cancan_ability_class = "Ability"
# You can specify a method to be called on unauthorized access.
# This is necessary in order to prevent a redirect loop which happens
# because, by default, user gets redirected to Dashboard. If user
# doesn't have access to Dashboard, he'll end up in a redirect loop.
# Method provided here should be defined in application_controller.rb.
# config.on_unauthorized_access = :access_denied
# == Current User
#
# Active Admin will associate actions with the current
# user performing them.
#
# This setting changes the method which Active Admin calls
# (within the application controller) to return the currently logged in user.
config.current_user_method = :current_admin_user
# == Logging Out
#
# Active Admin displays a logout link on each screen. These
# settings configure the location and method used for the link.
#
# This setting changes the path where the link points to. If it's
# a string, the strings is used as the path. If it's a Symbol, we
# will call the method to return the path.
#
# Default:
config.logout_link_path = :destroy_admin_user_session_path
# This setting changes the http method used when rendering the
# link. For example :get, :delete, :put, etc..
#
# Default:
config.logout_link_method = :delete
# == Root
#
# Set the action to call for the root path. You can set different
# roots for each namespace.
#
# Default:
config.root_to = 'tenants#index'
# == Admin Comments
#
# This allows your users to comment on any resource registered with Active Admin.
#
# You can completely disable comments:
config.comments = false
#
# You can change the name under which comments are registered:
# config.comments_registration_name = 'AdminComment'
#
# You can change the order for the comments and you can change the column
# to be used for ordering:
# config.comments_order = 'created_at ASC'
#
# You can disable the menu item for the comments index page:
# config.comments_menu = false
#
# You can customize the comment menu:
# config.comments_menu = { parent: 'Admin', priority: 1 }
# == Batch Actions
#
# Enable and disable Batch Actions
#
config.batch_actions = false
# == Controller Filters
#
# You can add before, after and around filters to all of your
# Active Admin resources and pages from here.
#
# config.before_action :do_something_awesome
# == Localize Date/Time Format
#
# Set the localize format to display dates and times.
# To understand how to localize your app with I18n, read more at
# https://github.com/svenfuchs/i18n/blob/master/lib%2Fi18n%2Fbackend%2Fbase.rb#L52
#
config.localize_format = :long
# == Setting a Favicon
#
# config.favicon = 'favicon.ico'
# == Meta Tags
#
# Add additional meta tags to the head element of active admin pages.
#
# Add tags to all pages logged in users see:
# config.meta_tags = { author: 'My Company' }
# By default, sign up/sign in/recover password pages are excluded
# from showing up in search engine results by adding a robots meta
# tag. You can reset the hash of meta tags included in logged out
# pages:
# config.meta_tags_for_logged_out_pages = {}
# == Removing Breadcrumbs
#
# Breadcrumbs are enabled by default. You can customize them for individual
# resources or you can disable them globally from here.
#
config.breadcrumb = false
# == Create Another Checkbox
#
# Create another checkbox is disabled by default. You can customize it for individual
# resources or you can enable them globally from here.
#
# config.create_another = true
# == Register Stylesheets & Javascripts
#
# We recommend using the built in Active Admin layout and loading
# up your own stylesheets / javascripts to customize the look
# and feel.
#
# To load a stylesheet:
# config.register_stylesheet 'my_stylesheet.css'
#
# You can provide an options hash for more control, which is passed along to stylesheet_link_tag():
# config.register_stylesheet 'my_print_stylesheet.css', media: :print
#
# To load a javascript file:
# config.register_javascript 'my_javascript.js'
# == CSV options
#
# Set the CSV builder separator
# config.csv_options = { col_sep: ';' }
#
# Force the use of quotes
# config.csv_options = { force_quotes: true }
# == Menu System
#
# You can add a navigation menu to be used in your application, or configure a provided menu
#
# To change the default utility navigation to show a link to your website & a logout btn
#
# config.namespace :admin do |admin|
# admin.build_menu :utility_navigation do |menu|
# menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: :blank }
# admin.add_logout_button_to_menu menu
# end
# end
#
# If you wanted to add a static menu item to the default menu provided:
#
# config.namespace :admin do |admin|
# admin.build_menu :default do |menu|
# menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: :blank }
# end
# end
# == Download Links
#
# You can disable download links on resource listing pages,
# or customize the formats shown per namespace/globally
#
# To disable/customize for the :admin namespace:
#
config.namespace :admin do |admin|
#
# # Disable the links entirely
admin.download_links = false
#
# # Only show XML & PDF options
# admin.download_links = [:xml, :pdf]
#
# # Enable/disable the links based on block
# # (for example, with cancan)
# admin.download_links = proc { can?(:view_download_links) }
#
end
# == Pagination
#
# Pagination is enabled by default for all resources.
# You can control the default per page count for all resources here.
#
config.default_per_page = 30
#
# You can control the max per page count too.
#
config.max_per_page = 100
# == Filters
#
# By default the index screen includes a "Filters" sidebar on the right
# hand side with a filter for each attribute of the registered model.
# You can enable or disable them for all resources here.
#
# config.filters = true
#
# By default the filters include associations in a select, which means
# that every record will be loaded for each association.
# You can enabled or disable the inclusion
# of those filters by default here.
#
# config.include_default_association_filters = true
# == Footer
#
# By default, the footer shows the current Active Admin version. You can
# override the content of the footer here.
#
config.footer = 'Powered by abc.com'
# == Sorting
#
# By default ActiveAdmin::OrderClause is used for sorting logic
# You can inherit it with own class and inject it for all resources
#
# config.order_clause = MyOrderClause
config.clear_stylesheets!
config.register_stylesheet 'admin/active_admin.css'
config.clear_javascripts!
config.register_javascript 'admin/active_admin.js'

在 routes.rb 中，您可以执行的更改ActiveAdmin::Devise.config指向的会话控制器，其中（默认情况下）返回:controllers=>
{:sessions=>"active_admin/devise/sessions", ... }。
在ActiveAdmin 1.0.0.pre1中，可以在activeadmin-1.0.0.pre1/lib/active_admin/devise.rb中找到这些控制器。
您可以像这样设置您的sessions_controller ：
devise_for :admin_users, ActiveAdmin::Devise.config.deep_merge(controllers: { sessions: "some/custom/path/sessions" })，请注意其他配置保持不变。
然后，您必须在some/custom/path中创建 sessions_controller.rb ，例如：
class Some::Custom::Path::SessionsController < Devise::SessionsController
# As can be seen in 'activeadmin/lib/active_admin/devise.rb'
include ::ActiveAdmin::Devise::Controller
def after_sign_in_path_for(resource)
"your/custom/path"
end
end

也许有人有更好的解决方案，但这里有一个快速补丁来解决你的问题。
在config/active_admin.rb的底部，添加以下代码。
假设您已在routes.rb
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
class ActiveAdmin::Devise::SessionsController
def after_sign_in_path_for(resource)
case resource
when AdminUser then '/admin'
else super
end
end
def after_sign_out_path_for(resource)
'/admin'
end
end
注意：只要您对此文件进行任何更改，就需要重新启动服务器。

发布您的Gemfile.lock。如果您正在使用Devise，请确保它是最新版本。
