我试图让has_secure_password与mongoid玩得很好.我正在关注Railscasts#270,但是当我用用户名/密码登录时,我收到错误：
undefined method `find_by_email' for User:Class
我看到一个类似的帖子(https://stackoverflow.com/questions/6920875/mongoid-and-has-secure-password)但是,按照它的建议完成我仍然得到相同的错误.
这是我的模型：
class User include Mongoid::Document include ActiveModel::SecurePassword validates_presence_of :password,:on => :create attr_accessible :email,:password,:password_confirmation field :email,:type => String field :password_digest,:type => String has_secure_password end
控制器：
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])
session[:user_id] = user.id
redirect_to root_url,:notice => "Logged in!"
else
flash.now.alert = "Invalid email or password"
render "new"
end
end
def destroy
session[:user_id] = nil
redirect_to root_url,:notice => "Logged out!"
end
end
谢谢.
解决方法
选项1：在您的控制器中,您应该使用
user = User.where(:email => params[:email]).first
选项2：在您的模型中,您应该定义
def self.find_by_email(email) where(:email => email).first end
