我试图让has_secure_password与mongoid玩得很好。我正在关注Railscast#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
我看到一篇类似的帖子(http://stackoverflow.com/questions/6920875/mongoid-and-has-secure-password)但是,按照它的建议我仍然会得到同样的错误。
这是我的模特:
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
感谢。

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

Mongoid不支持find_by_attribute
方法。
您应该更好地使用where
:
User.where(:email => email).all
