    • 意图**

我已经创建了一个用户模型，正如Devise文档所指出的那样。稍后，我搭建了一个控制器和视图，以便有一个索引和一个可视化界面来处理我的用户。

    • 问题**

访问 * edit_user_path * 后，我向数据库提交了一个新用户，SQLite添加了记录（因此信息被保存），但发生了一些事情，我没有被重定向到根目录，而是得到了一个异常：

ActionController::UnknownFormat in Devise::RegistrationsController#create
    • 如何修复此异常并使Rails流向root_path？**

我在这里添加了这些文件，以便您能够了解正在发生的事情：

    • 路由. rb**
#RESTful routes
  devise_for :users
  resources :users, :except => [:create]

  resources :clans
  resources :games
  resources :matches

  #Root and debug
  root :to => 'debug#features'
    • 耙式路由**

当你在devise中得到ActionController::UnknownFormat in Devise::RegistrationsController#create时，大多数问题都出在你的注册表中，删除url部分中的resource_name
user_registration_path不需要额外的参数，您将resource_name传递给它，在您的示例中，resource_name等于user，它被解释为格式，因此您将得到类似http://localhost:3000/users.user的url（在本例中，user被设置为格式）。MORE
之前

form_for(resource, as: resource_name, url: user_registration_path(resource_name))

之后

form_for(resource, as: resource_name, url: user_registration_path)

我不知道是否与你的问题有关，但你有一些重复的（或更好的无用）路线，也许在你的控制器的行动。
根据bin/rake routes的结果

cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
       user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                         PATCH  /users(.:format)               devise/registrations#update
                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy
                   users GET    /users(.:format)               users#index
                         POST   /users(.:format)               users#create # <-- ?
                new_user GET    /users/new(.:format)           users#new  # <-- ?
               edit_user GET    /users/:id/edit(.:format)      users#edit  # <-- ?
                    user GET    /users/:id(.:format)           users#show
                         PATCH  /users/:id(.:format)           users#update  # <-- ?
                         PUT    /users/:id(.:format)           users#update  # <-- ?
                         DELETE /users/:id(.:format)           users#destroy  # <-- ?

您已经使用Devise RegistrationController管理了User资源上的new、create、edit、update和destroy操作，但是在/users/...路径下还列出了类似的操作，并且可能在UsersController中列出了相关的操作。
为了保持代码整洁并避免误解，最好只保留UsersControllers中有用的操作：index和show。
尝试更改您的routes.rb文件：

devise_for :users
resources :users, only: [:index, :show]
