Question

我尝试注销用户时收到此错误。我查了很多同样错误的帖子，但没有人解决我的错误，希望你能帮助我。

错误如下：

    ActiveRecord::RecordNotFound in UsersController#destroy 
Couldn't find User with 'id'=sign_out

以下是我的代码：

users_controller.rb

    def destroy
      @user.destroy
      respond_to do |format|
        format.html { redirect_to unauthenticated_root_path }
        format.json { head :no_content }
      end
    end

    private

    private
    # Use callbacks to share common setup or constraints between actions.
    def set_user
      @user = User.find(params[:id])
    end

查看/用户/ index.html.erb

<li>
    <%= link_to "Logout", destroy_user_session_path, :method => :delete %>
  </li>

的routes.rb

    Rails.application.routes.draw do
  get 'admin/index'

  resources :contacts

  resources :afections

  resources :injuries

  resources :allergies

  resources :trainers

  resources :idusuarios

  resources :diseases

  resources :weights

  resources :diets

  resources :exercices

  resources :profiles

  resources :users

  devise_for :users

  get '/users/sign_out' => 'devise/sessions#destroy'

  devise_scope :user do
    authenticated :user do
      root 'pagina#index', as: :authenticated_root
    end

    unauthenticated do
      root 'devise/sessions#new', as: :unauthenticated_root
    end
  end
end

Answer 1

在您的路线中将get '/users/sign_out' => 'devise/sessions#destroy'移到resources :users之上。路由在路由文件中的顺序优先。

Answer 2

在路线中使用resources :users时，您有以下路线：

/users
/users/:id
/users/:id/edit
and ...

因此，当调用/users/sign_out时，认为sign_out是一个ID。

例如，将/users/sign_out更改为/user/sign_out。

BUT

如果要自定义会话路径，可以执行以下操作：

自定义会话路径：

as :user do
    get 'user/signin' => 'devise/sessions#new', :as => :new_user_session
    post 'user/signin' => 'devise/sessions#create', :as => :user_session
    delete 'user/signout' => 'devise/sessions#destroy', :as => :destroy_user_session, via: [:delete, :get]
end

并在设计中跳过会话：

 devise_for :users, :skip => [:sessions]

如果您想要用户注册，您必须在设计中跳过它，然后才能使用用户脚手架：

as :user do
    get 'user/signin' => 'devise/sessions#new', :as => :new_user_session
    post 'user/signin' => 'devise/sessions#create', :as => :user_session
    delete 'user/signout' => 'devise/sessions#destroy', :as => :destroy_user_session, via: [:delete, :get]
end
scope "admin" do                
    resources :users 
    devise_for :users, :skip => [:sessions, :registrations]
end

尝试注销时出错：无法找到带有＆＃39; id＆＃39; = sign_out的用户
