在示例登录程序中,我有两个类。会话和用户。用户表有两个字段名,密码。调用用户类的身份验证方法时,会话方法继续获取“NoMethodError”。
用户类如下所示:
class UserController < ApplicationController
def index
@user = User.find(:first, :order => 'RANDOM()')
end
def show
@user = User.find(:all)
end
def new
@user = User.new
#redirect_to user_path
end
def create
@user = User.new(params[:user])
@user.save
#redirect_to 'http://localhost:3000/user/show'
end
def self.authenticate( password)
#user = User.find_by_name(name)
if user.find_by_password(password)#match_password(password)
return true
else
return false
end
end
def self.match_password(password="")
encrypted_password == BCrypt::Engine.hash_secret(password, salt)
end
end
session 类有 create 方法,该方法调用用户的 authenticate fn。这是创建方法
def create
user = User.find_by_name(params[:session][:name].downcase)
if user && user.authenticate(params[:session][:password])
# Sign the user in and redirect to the user's show page.
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination' # Not quite right!
render 'new'
end
end
这是堆栈
