[英]Rails not saving model field
我想知道為什么我的rails不保存我的encryption_password字段。
這是我的UserController
class UserController < ApplicationController
require 'bcrypt'
before_filter :save_login_state, :only => [:new, :create]
def new
new_user = User.new(user_params)
new_user.numRatings = 0
if new_user.save
flash[:notice] = "You signed up successfully"
flash[:color]= "valid"
else
flash[:notice] = "Form is invalid"
flash[:color]= "invalid"
end
redirect_to(:controller => 'sessions', :action => 'login')
end
def create
end
def update
end
def view
end
private
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation)
end
end
這是我的用戶模型
class User < ActiveRecord::Base
require 'BCrypt'
attr_accessor :password, :encrypted_password
EMAIL_REGEX = /\A[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\z/i
validates :email, :presence => true, :uniqueness => true, :format => EMAIL_REGEX
validates :name, :presence => true
validates :password, :confirmation => true, :presence => true, :on => :create
before_save :encrypt_password
after_save :clear_password
def encrypt_password
if password.present?
self.salt = BCrypt::Engine.generate_salt
self.encrypted_password = BCrypt::Engine.hash_secret(password, salt)
end
end
def clear_password
self.password = nil
end
def self.authenticate(username_or_email="", login_password="")
if EMAIL_REGEX.match(username_or_email)
user = User.find_by_email(username_or_email)
end
if user && user.match_password(login_password)
return user
else
return false
end
end
def match_password(login_password="")
encrypted_password == BCrypt::Engine.hash_secret(login_password, salt)
end
end
另外,我用這個功能來保存它
def login_attempt
authorized_user = User.authenticate(params["user"]["email"],params["user"]["password"])
if authorized_user
session[:user_id] = authorized_user.id
flash[:notice] = "Wow Welcome again, you logged in as #{authorized_user.username}"
redirect_to(:action => 'home')
else
flash[:notice] = "Invalid Username or Password"
flash[:color]= "invalid"
render "login"
end
end
我懷疑我創建了第一次遷移的一件事
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :email
t.string :password
t.string :name
t.float :rating
t.integer :numRatings
t.timestamps
end
end
end
但是,我將:password字段更改為:encrypted_password,並將其反映在表中。 我已經堅持了兩個小時。 我想知道是否還有任何東西。 謝謝。
日志顯示正在注入數據減去加密密碼
插入“用戶”(“ created_at”,“電子郵件”,“名稱”,“ numRatings”,“鹽”,“ updated_at”)值(?,?,?,?,?,?)[[“ created_at”, “ 2014-08-05 06:22:41.335373”],[“電子郵件”,“ w@w.com”],[“名稱”,“ w”],[“ numRatings”,0],[“鹽” ,“ $ 2a $ 10 $ pagmnNzT4FWEBmaPmiLX1u”],[“ updated_at”,“ 2014-08-05 06:22:41.335373”]]
您的attr_accessor :encrypted_password
突出顯示-這將覆蓋Rails生成的屬性getter / setter,該屬性將在模型實例中簡單設置一個名為@encrypted_password
的實例變量。
您提到您將Migration :password field
更改為:encrypted_password field
,但是您確定要重新初始化模型嗎? 即正確遷移了更改? 最后,如果您確實更改了遷移,則無需使用attr_accessor
的encrypted_password
。 同時擁有它們可能會導致陰影並成為問題。
