Ruby on rails Rails：用户创建其他验证

我有一个带有地址列的常规用户模型。但当一个人试图用电子邮件和密码注册时，他会收到一个错误：zip地址和城镇不能为空。您只需注册电子邮件和密码。如何修复用户创建

用户模型：

class User < ActiveRecord::Base
      attr_accessible :zip, :state, :town, :address, :email, :password, :password_confirmation,

      attr_accessor :password
      validates_confirmation_of :password
      validates :email, presence: true, format: { with: VALID_E_REGEX }, uniqueness: { case_sensitive: false }
      validates :password, presence: true, format:{  with: VALID_P_REGEX }, if: proc{ password_salt.blank? || password_hash.blank? } 
      validates :zip, format: { with: VALID_ZIP_REGEX }
      validates :address, length: { minimum: 5 }
      validates :town, length: { minimum: 4 }
    end

class用户

用户控制器：

class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      redirect_to root_url, :notice => "Signed up!"
    else
      render "new"
    end
  end 
end

class UsersController“已注册！”
其他的
呈现“新”
结束
结束
结束

错误：

!! #<ActiveRecord::RecordInvalid: Validation failed: Phone number is invalid, Zip is invalid, Address is too short (minimum is 5 characters), Town is too short (minimum is 4 characters)>

#

删除模型中不必要的验证。就这么简单

如果只想在值存在时使用它，可以使用validate的allow\u nil或allow\u blank选项。或者也可以使用if条件

class User < ActiveRecord::Base
      attr_accessible :zip, :state, :town, :address, :email, :password, :password_confirmation,

      attr_accessor :password
      validates_confirmation_of :password
      validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
      validates :password, presence: true, format:{  with: VALID_PASSWORD_REGEX }, if: proc{ password_salt.blank? || password_hash.blank? }
      validates :zip, format: { with: VALID_ZIP_REGEX }, allow_blank: true
      validates :address, length: { minimum: 5 }, allow_blank: true
      validates :town, length: { minimum: 4 }, allow_blank: true
    end

validates :address, length: { minimum: 5 }, if: :address

让验证有条件怎么样

class User < ActiveRecord::Base
      attr_accessible :zip, :state, :town, :address, :email, :password, :password_confirmation,

      attr_accessor :password
      validates_confirmation_of :password
      validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness: { case_sensitive: false }
      validates :password, presence: true, format:{  with: VALID_PASSWORD_REGEX }, if: proc{ password_salt.blank? || password_hash.blank? }
      validates :zip, format: { with: VALID_ZIP_REGEX }, allow_blank: true
      validates :address, length: { minimum: 5 }, allow_blank: true
      validates :town, length: { minimum: 4 }, allow_blank: true
    end

validates :address, length: { minimum: 5 }, if: :address

这取决于你想要的实际行为

• 如果您不想验证额外的属性，只需按照Vamsi的说法删除它们的验证

• 如果要验证额外属性，但不是在创建用户对象时，可以在：：update上添加

  ，如下所示：
  
  验证：zip，格式：{with:VALID\u zip\u REGEX}，on：：update
  

• 如果您希望验证额外属性，但仅在实际输入这些属性时，您可以像这样添加

  allow\u blank:true

  （或者

  allow\u nil

  ，这同样取决于您的需要）：

  验证：zip，格式：{with:VALID\u zip\u REGEX}，允许\u blank:true
