設計和password_confirmation驗證

我在設計和密碼確認方面遇到問題。我創建了一個rails4模型試驗，看起來像這樣：在第二斷言（"Password confirmation should be required"）設計和password_confirmation驗證

test "user requires a password_confirmation" do 
    user = FactoryGirl.build(:user) 
    assert user.valid?, "FactoryGirl should return a valid user" 

    user.password_confirmation = nil 

    # These are just some outputs to verify what's going on. 
    # This is the condition in devises's password_required? method 
    puts !user.persisted? || !user.password.nil? || !user.password_confirmation.nil? #=> true 
    puts user.valid? #=> true 

    assert user.invalid?, "Password confirmation should be required" # Fails here 
    assert_equal 1, user.errors.size, "Only one error should have occured. #{user.errors.full_messages}" 
end

此測試失敗。

這裏是我完整的用戶模式：

class User < ActiveRecord::Base 
    has_one :user_entity 

    has_one :manager,through: :user_entity, source: :entity, source_type: 'Manager' 
    has_one :client, through: :user_entity, source: :entity, source_type: 'Client' 

    # Adds default behavior. See: https://github.com/stanislaw/simple_roles#many-strategy 
    simple_roles 

    validates :username, 
    presence: true, 
    length: { minimum: 4, allow_blank: true, if: :username_changed? }, 
    uniqueness: { allow_blank: true, if: :username_changed? }, 
    format: { with: /\A[A-z_0-9]+\z/, allow_blank: true, if: :username_changed? } 

    # Include default devise modules. Others available are: 
    # :token_authenticatable, :timeoutable, :omniauthable, :registerable 
    devise :database_authenticatable, :recoverable, :rememberable, 
      :trackable, :validatable, :confirmable, :lockable 

    # Virtual attribute for authenticating by either username or email 
    # This is in addition to a real persisted field like 'username' 
    attr_accessor :login 

    def self.find_first_by_auth_conditions(warden_conditions) 
    conditions = warden_conditions.dup 

    # User need to be active 
    conditions[:active] = true 

    if login = conditions.delete(:login) 
     where(conditions).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first 
    else 
     where(conditions).first 
    end 
    end 

    def entity 
    self.user_entity.try(:entity) 
    end 

    def entity=(newEntity) 
    self.build_user_entity(entity: newEntity) 
    end 

end

我試着將我的用戶模型：

validates :password, confirmation: true

該測試通過後，但我得到下一個錯誤：

1) Failure: 
UserTest#test_user_requires_a_password [/my/project/test/models/user_test.rb:52]: 
Two errors should have occured. ["Password confirmation doesn't match confirmation", "Password confirmation doesn't match confirmation", "Password can't be blank"]. 
Expected: 2 
    Actual: 3

正如您所看到的，這就像確認驗證發生兩次並且兩次都失敗。

我正在使用rails4（edge）和rails4分支進行設計。

編輯：我試着設置

user.password_confirmation = "#{user.password}_diff"

並測試通過。那麼爲什麼nil設置時忽略確認？由於對象尚未持續，我會假設必須提供密碼確認。

我知道這是一個老問題，但我遇到了同樣的問題。

首先，從模型中刪除此這樣你就不會得到重複的驗證檢查：

validates :password, confirmation: true

然後添加以下。我把它改爲只工作在創建：

validates :password_confirmation, presence: true, on: :create

見validates_confirmation_of節上this apidock page：

注：僅在password_confirmation不無執行這項檢查。要確認，請確保爲確認屬性添加狀態檢查：

validates_presence_of：password_confirmation，如果:: password_changed？
