插入新記錄到數據庫

我使用Ubuntu上的Rails 3.2.3及以下時，遇到了一個錯誤是我的架構文件和模型文件代碼：插入新記錄到數據庫

schema.rb

ActiveRecord::Schema.define(:version => 20120528062318) do 

    create_table "users", :force => true do |t| 
    t.string "name" 
    t.string "email" 
    t.datetime "created_at",  :null => false 
    t.datetime "updated_at",  :null => false 
    t.string "password_digest" 
    end 

    add_index "users", ["email"], :name => "index_users_on_email", :unique => true 

end

user.rb

class User < ActiveRecord::Base 
    attr_accessible :email, :name, :password, :password_confirmation 
    has_secure_password 

    before_save { |user| user.email = email.downcase } 
    valides :name, presence: true, length: { maximum: 50 } 
    VALID_EMAIL_REGEX = /\A[\w+\-.][email protected][a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, 
        uniqueness: true 
    validates :password, presence: true, length: { minimum: 6 } 
    validates :password_confirmation, presence: true 
end

我試圖從rails控制檯輸入一個新的記錄，命令如下：User.create（name：'Hilal Agil'，email：'[email protected]'，密碼：'welcome'，password_confirmation''歡迎'），我得到以下錯誤：

任何想法我在做什麼錯在這裏？謝謝。

你有一個錯字。這條線：

valides :name, presence: true, length: { maximum: 50 }

應該這樣說：

validates :name, presence: true, length: { maximum: 50 }

如果你看一下錯誤信息，你可以看到它是在告訴你，你正試圖調用一個方法名valides，這不不存在。
