嵌套属性中的 Rails/Mongoid 错误消息

发布于 2024-10-28 19:42:29 字数 759 浏览 4 评论 0原文

我有一个如下定义的联系信息类:

class ContactInfo
  include Mongoid::Document

  validates_presence_of :name, :message => ' cannot be blank'

  field :name, :type => String
  field :address, :type => String
  field :city, :type => String
  field :state, :type => String
  field :zip, :type => String
  field :country, :type => String
  embedded_in :user
end

此联系信息类作为嵌套属性嵌入到我的用户类中:

class PortalUser
  include Mongoid::Document
  accepts_nested_attributes_for :contact_info
end

当我尝试保存没有名称的用户时,我收到如下错误消息:

联系信息无效

但是,这对最终用户来说不是很有用,因为他或她不知道哪些联系信息无效。真实消息应该是“名称不能为空”。然而,这个错误并没有向上传播。有没有办法在 user.errors 中获取“名称不能为空”消息,而不是“联系信息无效”错误消息?

谢谢

I have a contact info class defined like this:

class ContactInfo
  include Mongoid::Document

  validates_presence_of :name, :message => ' cannot be blank'

  field :name, :type => String
  field :address, :type => String
  field :city, :type => String
  field :state, :type => String
  field :zip, :type => String
  field :country, :type => String
  embedded_in :user
end

This contact info class is embedd as a nested attribute inside my user class:

class PortalUser
  include Mongoid::Document
  accepts_nested_attributes_for :contact_info
end

When I attempt to save a user without a name, I get an error message like this:

Contact info is invalid

However, this is not very useful to the end user, because he or she doesn't know what contact info is invalid. The REAL message should be 'Name cannot be blank'. However, this error is not being propagated upwards. Is there a way to get the 'Name cannot be blank' message inside the user.errors instead of the 'Contact info is invalid' error message?

Thanks

这是我最终想出的解决方案:

将这些行添加到用户类中

after_validation :handle_post_validation
def handle_post_validation
  if not self.errors[:contact_info].nil?
    self.contact_info.errors.each{ |attr,msg| self.errors.add(attr, msg)}
    self.errors.delete(:contact_info)
  end
end

Here's the solution I eventually came up with:

Added these lines to the user class

after_validation :handle_post_validation
def handle_post_validation
  if not self.errors[:contact_info].nil?
    self.contact_info.errors.each{ |attr,msg| self.errors.add(attr, msg)}
    self.errors.delete(:contact_info)
  end
end

不是返回 user.errors.full_messages 而是为您的用户模型创建一个特定的错误消息方法,您可以在其中处理所有嵌入的文档错误。

class PortalUser
  include Mongoid::Document
  accepts_nested_attributes_for :contact_info
  def associated_errors
    contact_info.errors.full_messages unless contact_infos.errors.empty?
  end
end

并在你的控制器中

flash[:error] = user.associated_errors

Instead of returning the user.errors.full_messages create a specific error message method for your user model where you handle all your embedded document errors.

class PortalUser
  include Mongoid::Document
  accepts_nested_attributes_for :contact_info
  def associated_errors
    contact_info.errors.full_messages unless contact_infos.errors.empty?
  end
end

and in your controller

flash[:error] = user.associated_errors

我的解决方案涵盖了每个嵌入文档验证错误,如下所示:

  after_validation :handle_post_validation
  def handle_post_validation
    sub_errors = ActiveModel::Errors.new(self)
    errors.each do |e|
      public_send(e).errors.each { |attr,msg| sub_errors.add(attr, msg)}
    end
    errors.merge!(sub_errors)
  end

My solution that covers each embedded document validation error is the following:

  after_validation :handle_post_validation
  def handle_post_validation
    sub_errors = ActiveModel::Errors.new(self)
    errors.each do |e|
      public_send(e).errors.each { |attr,msg| sub_errors.add(attr, msg)}
    end
    errors.merge!(sub_errors)
  end

控制器中可能有一个解决方案...

在创建操作中,您可以添加类似

params[:portal_user][:contact_info_attributes] = {} if params[:portal_user] && 的 内容params[:portal_user][:contact_info_attributes].nil?

这将强制创建 contact_info,并会在右侧字段上触发错误

如果不添加此内容,则不会创建 contact_info

There might be a solution in the controller...

in the create action you can add something like

params[:portal_user][:contact_info_attributes] = {} if params[:portal_user] && params[:portal_user][:contact_info_attributes].nil?

This will force contact_info creation, and will trigger an error on the right field

If you don't add this, contact_info is not created
