我正在 Rails 中使用设备,但现在无法注销我的用户。
当我使用 users/log_out 页面时,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
我的设备迁移文件:
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.string :unconfirmed_email # Only if using reconfirmable
## Lockable

# t.string :unlock_token # Only if unlock strategy is :email or :both

# 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'
