In Devise Validatable module contains validates_uniqueness_of :email, :allow_blank => true, :if => :email_changed? How to disable this validator?

推荐答案

每 Devise自己的可验证模块的文档 ...

可验证创建用户电子邮件和密码所需的所有验证。 这是可选的，您可能希望自己创建验证。自动验证电子邮件是否存在，唯一且格式有效。还测试密码，确认和长度的存在。

Validatable creates all needed validations for a user email and password. It's optional, given you may want to create the validations by yourself. Automatically validate if the email is present, unique and its format is valid. Also tests presence of password, confirmation and length.

强调我的重点。

您应该禁用 Validatable 模块，并滚动您自己的验证。

You should disable the Validatable module and roll your own validations.

devise :database_authenticatable, :registerable, :rememberable,
       :trackable, :timeoutable, :confirmable, :recoverable, :lockable
       # :validatable <-- this one needs to go

查看 lib / devise / models / validatable.rb 并将相关部分拉入您自己的User类。对于当前 3.2.x 版本行，应该看起来像这样...

Review the contents of lib/devise/models/validatable.rb and pull the relevant sections into your own User class. For the current 3.2.x version line, it should look something like this...

class User < ActiveRecord::Base

  # From Devise module Validatable
  validates_presence_of   :email, if: :email_required?
  validates_uniqueness_of :email, allow_blank: true, if: :email_changed?
  validates_format_of     :email, with: email_regexp, allow_blank: true, if: :email_changed?

  validates_presence_of     :password, if: :password_required?
  validates_confirmation_of :password, if: :password_required?
  validates_length_of       :password, within: password_length, allow_blank: true

  # [ ... ] The rest of your model stuff

  protected

  # From Devise module Validatable
  def password_required?
    !persisted? || !password.nil? || !password_confirmation.nil?
  end

  # From Devise module Validatable
  def email_required?
    true
  end

end

然后make
