[英]Rails 3.1 Mongoid has_secure_password
I'm attempting to get has_secure_password to play nice with mongoid. 我试图让has_secure_password与mongoid玩得很好。 I'm following Railscasts #270, however when I to signin with a username/password, I get the error:
我正在关注Railscasts#270,但是当我用用户名/密码登录时,我收到错误消息:
undefined method `find_by_email' for User:Class
I see a similar post (http://stackoverflow.com/questions/6920875/mongoid-and-has-secure-password) however, having done as it suggested I still get the same error. 我看到一个类似的帖子(http://stackoverflow.com/questions/6920875/mongoid-and-has-secure-password)但是,按照它的建议我仍然得到相同的错误。
Here is my model: 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
Controller: 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
Thanks. 谢谢。
Option 1: In your controller, you should use 选项1:在您的控制器中,您应该使用
user = User.where(:email => params[:email]).first
Option 2: In your model, you should define 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 doesn't support the find_by_attribute
methods. Mongoid不支持
find_by_attribute
方法。
You should better use where
instead: 你应该更好地使用
where
:
User.where(:email => email).all
