[英]RoR - ArgumentError in SessionsController#create wrong number of arguments (1 for 2)
I am new to RoR and I am following this tutorial on making a user authentication system from scratch: http://railscasts.com/episodes/250-authentication-from-scratch . 我是RoR的新手,我正在按照本教程从头开始创建用户身份验证系统: http : //railscasts.com/episodes/250-authentication-from-scratch 。 I've been hung up on this error message all weekend:
我整个周末都被这个错误消息挂断了:
ArgumentError in SessionsController#create: wrong number of arguments (1 for 2).
Here is the code from my sessions controller: 这是我的会话控制器的代码:
class SessionsController < ApplicationController
def new
end
def create
user = User.authenticate(:email => params[:email], :password => params[:password])
if user
session[:user_id] = user.id
redirect_to root_url, :notice => "Logged in!"
else
flash.now.alert = "Invalid email or password"
render "new"
end
end
end
Here is the code from my user.rb
model (The error message gives an extracted source on line #10 => def self.authenticate (email, password)
这是来自我的
user.rb
模型的代码(错误消息在第10行提供了一个提取的源= = def self.authenticate (email, password)
class User < ActiveRecord::Base
attr_accessor :password
validates_confirmation_of :password
validates_presence_of :email
validates_uniqueness_of :email
validates_presence_of :password, :on => :create # needed to move line up from below to. Cannot encrypt password without validating password
before_save :encrypt_password
def self.authenticate (email, password)
user = find_by_email(email)
if user && user.password_hash == BCrypt::Engine.hash_secret(password, user.password_salt)
user
else
nil
end
end
def encrypt_password
if password.present?
self.password_salt = BCrypt::Engine.generate_salt
self.password_hash = BCrypt::Engine.hash_secret(password, password_salt)
end
end
end 结束
authenticate
method in the model takes two parameters, but you're passing just one (a hash with two keys). 模型中的
authenticate
方法有两个参数,但是你只传递一个(带有两个键的哈希)。 Change it to: 将其更改为:
User.authenticate(params[:email], params[:password])
The problem is in this line: 问题出在这一行:
user = User.authenticate(:email => params[:email], :password => params[:password])
it should be 它应该是
user = User.authenticate(params[:email], params[:password])
