Rails remember_token 会话不起作用 [英] Rails remember_token session not working

问题描述

我是 Ruby on Rails 的新手.我正在通过互联网上提供的 Michel Hartl 的参考文档学习它.但是我在用户登录过程中遇到了一个问题，我怀疑 before_save 没有调用 create_remember_token 方法.我试图从很长一段时间内调试这个问题.我的代码如下:

I am new to Ruby on Rails. I am learning it through Michel Hartl's reference doc available on the internet. However i ran into a problem during sign-in of users, I suspect the before_save is not calling the create_remember_token method. I am trying to debug this issue from a very long time. My code is as follows:

user.rb 文件:

user.rb file:

# == Schema Information
#
# Table name: users
#
#  id              :integer(4)      not null, primary key
#  name            :string(255)
#  email           :string(255)
#  created_at      :datetime        not null
#  updated_at      :datetime        not null
#  password_digest :string(255)
#  username        :string(255)
#  remember_token  :string(255)
#

class User < ActiveRecord::Base
def to_param
username
end
attr_accessible :name, :email, :password, :password_confirmation, :username
has_secure_password


before_save { |user| user.email = email.downcase }
before_save :create_remember_token

private

def create_remember_token
 self.remember_token = SecureRandom.urlsafe_base64
end
end

session_helper.rb

session_helper.rb

module SessionsHelper

def sign_in(user)
cookies.permanent[:remember_token] = user.remember_token
current_user = user
end

def current_user=(user)
  @current_user = user
end

def current_user
 @current_user ||= user_from_remember_token
end

def signed_in?
 !current_user.nil?
end

private

def user_from_remember_token
  remember_token = cookies[:remember_token]
  User.find_by_remember_token(remember_token) unless remember_token.nil?
end   
end

sessions_controller.rb:

sessions_controller.rb:

class SessionsController < ApplicationController
def new

end

def create
    user=User.find_by_username(params[:session][:username])
    if user && user.authenticate(params[:session][:password])
        sign_in user
        redirect_to "/@/#{params[:session][:username]}"
    else
        flash.now[:error] = "Login failed! Please try again!"
        render 'new'
    end
end

def destroy

end
end

请帮助我，让我知道问题出在哪里.干杯:)

Please help me and let me know as to where the problem exists. Cheers :)

推荐答案

我在一年前发布了这个问题.现在我使用 Devise gem 进行身份验证.一切都按预期进行.

I had posted this question a year ago. Now I am using the Devise gem for authentication. Everything is working as expected.

谢谢
