ruby-on-rails – Rails_Admin显示路由错误“无路由匹配{：contr

导读：我按照说明安装了Rails_Admin,也使用了Devise.当我尝试导航到“/ admin”时,我收到以下错误： Routing ErrorNo route matches {:controller="home"} 这是我的routes.rb： Ot::Application.routes.draw do resources :badgeships resources :badges resources

我按照说明安装了Rails_Admin,也使用了Devise.当我尝试导航到“/ admin”时,我收到以下错误：
Routing Error
No route matches {:controller=>"home"}
这是我的routes.rb： Ot::Application.routes.draw do
resources :badgeships
resources :badges
resources :profiles
resources :universities
resources :degrees
resources :jobs
resources :resources
resources :communities
resources :networks
resources :topics do
resources :posts
end
get 'topics/tag/:tag',to: 'topics#index',as: :topic_tag
get 'resources/tag/:tag',to: 'resources#index',as: :resource_tag
root :to => 'home#index'
devise_for :users,path_names: {sign_in: "login",sign_out: "logout"}
mount RailsAdmin::Engine => '/admin',:as => 'rails_admin'
end
这是我的rails_admin.rb初始化程序： RailsAdmin.config do |config|
config.main_app_name = ["Cool app","BackOffice"]
# or somethig more dynamic
config.main_app_name = Proc.new { |controller| [ "Cool app","BackOffice - #{controller.params[:action].try(:titleize)}" ] }
end
有关如何让rails_admin正常工作的任何想法？ 更新：这是我的佣金路线： [RailsAdmin] RailsAdmin initialization disabled by default. Pass SKIP_RAILS_ADMIN_INITIALIZER=false if you need it.

以下是我安装rails_admin的方法： rails g rails_admin:install

- Hello,RailsAdmin installer will help you set things up!
- I need to work with Devise,let's look at a few things first:
- Checking for a current installation of devise...
- Found it!
- Looks like you've already installed it,good!
? Where do you want to mount rails_admin? Press <enter> for [admin] > manage
gsub config/routes.rb
route mount RailsAdmin::Engine => '/manage',:as => 'rails_admin'
- And you already set it up,good! We just need to know about your user model name...
- We found 'user' (should be one of 'user','admin',etc.)
? Correct Devise model name if needed. Press <enter> for [user] > User
- Now setting up devise with user model name 'User':
generate devise

- Now you'll need an initializer...
- You already have a config file. You're updating,heh? I'm generating a new 'rails_admin.rb.example' that you can review.

解决方法
编辑：找到修复程序.见
this SO discussion.
进入主ApplicationController并进行更改 rescue_from CanCan::AccessDenied do |e| redirect_to root_path,alert: e.message end 至 rescue_from CanCan::AccessDenied do |e| redirect_to '/',alert: e.message end 给它任何符号路径名称将导致RoutingException,因为Rails正在错误的路由表中查找名称.指定文字根路径会绕过查找,并在处理它时为主应用程序的ApplicationController提供第一个破解.这是你想要的. 小时以下的原帖： 我遇到了类似的错误,如果非管理员用户访问我的’/ admin’路由,那么ActiveAdmin CanCan会尝试将他踢出去. (顺便说一下,通过添加better_errors Gem可以获得更清晰的错误报告.)我得到异常报告,我可以在发生路由故障时在本地变量中看到正确的错误消息. 我还可以看到,感谢better_errors的“live shell”,生成RoutingError的ActionController是RailsAdmin :: MainController.这告诉我,我们需要弄清楚如何告诉RailsAdmin重定向到应用程序根路径,而不是引擎根路径. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
