找不到具有’id’= sign_out的用户
我正在使用rails中的设计，我现在无法注销我的用户。
当我使用users / log_out页面时，它会出现以下错误：
ActiveRecord::RecordNotFound in UsersController#show Couldn't find User with 'id'=sign_out 无论如何，这是我的用户控制器：
class UsersController < ApplicationController def new @user = User.new end def create @user = User.new(user_params) if @user.save redirect_to users_path else render 'new' end end def index @users=User.all end def edit @user = User.find(params[:id]) end def destroy @user = User.find(params[:id]) @user.destroy redirect_to users_path end def update @user = User.find(params[:id]) if @user.update_attributes(user_params) redirect_to user_path(@user.id) else render 'edit' end end def show @user = User.find(params[:id]) end private def user_params params.require(:user).permit(:name, :email, :password) end end
我的路线.rb：
Rails.application.routes.draw do devise_for :users do get "/users/sign_out" => "devise/sessions#destroy", :as => :destroy_user_session end resources :posts resources :users end
我的设计迁移文件：
class AddDeviseToUsers < ActiveRecord::Migration def self.up change_table(:users) do |t| ## Database authenticatable t.string :email, null: false, default: "" t.string :encrypted_password, null: false, default: "" ## Recoverable t.string :reset_password_token t.datetime :reset_password_sent_at ## Rememberable t.datetime :remember_created_at ## Trackable t.integer :sign_in_count, default: 0, null: false t.datetime :current_sign_in_at t.datetime :last_sign_in_at t.string :current_sign_in_ip t.string :last_sign_in_ip ## Confirmable # t.string :confirmation_token # t.datetime :confirmed_at # t.datetime :confirmation_sent_at # t.string :unconfirmed_email # Only if using reconfirmable ## Lockable # t.integer :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts # t.string :unlock_token # Only if unlock strategy is :email or :both # t.datetime :locked_at # Uncomment below if timestamps were not included in your original model. # t.timestamps end add_index :users, :email, unique: true add_index :users, :reset_password_token, unique: true # add_index :users, :confirmation_token, unique: true # add_index :users, :unlock_token, unique: true end def self.down # By default, we don't want to make any assumption about how to roll back a migration when your # model already existed. Please edit below which fields you would like to remove in this migration. raise ActiveRecord::IrreversibleMigration end end
应用程序跟踪如下：
app/controllers/users_controller.rb:40:in `show'
validationapplication.js中是否包含以下内容
//= require jquery //= require jquery_ujs
jquery_ujs代表Unobtrusive JavaScript，这可以确保很多东西（比如delete方法）按预期工作。
请参阅Rafik的答案： 找不到ID = sign_out的用户
设备users路由在users/sign_out之前匹配。 这就是为什么它试图找到一个id为sign_out的User 。
尝试更改注销路线
get "/logout" => "devise/sessions#destroy", :as => :destroy_user_session end
应该管用。
我认为POST更适合退出操作：
post "/logout" => "devise/sessions#destroy", :as => :destroy_user_session end
我认为您应该使用以下方式定义您的路线：
devise_for :users do delete "/logout" => "devise/sessions#destroy", :as => :destroy_user_session end
