问题描述
本正常工作
[MetadataType(typeof(Area_Validation))]
public partial class Area
{
...
}
public class Area_Validation
{
[Required(ErrorMessage = "Please add this field.")]
public int Email { get; set; }
[Required(ErrorMessage = "Please add this field")]
public string Name { get; set; }
}
但如何如果 Area_Validation
的动态创建?例如订阅字段的是后端可以由用户创建,并最终像这样:
but how about if Area_Validation
is dynamically created? for example Subscription Fields that on back-end can be created by the user and end up like this:
如何设置元上的每个字段的自动验证
How can I set the Metadata on each field for auto validation?
目前我做的:
public class SubscriberFormViewModel
{
public List<SubscriberFieldModel> Fields { get; private set; }
public Calendar Calendar { get; private set; }
public Company Company { get; private set; }
public SubscriberFormViewModel()
{
// TODO: This is only for testing while validation is not set
}
public SubscriberFormViewModel(Decimal calendarId)
{
if (calendarId > 0)
{
SubscribersRepository db = new SubscribersRepository();
Calendar calendar = db.GetCalendarById(calendarId);
Company company = db.GetCompanyById(calendar.company_id);
this.Fields = db.FindAllSubscriberFieldsByCalendar(calendarId);
this.Calendar = calendar;
this.Company = company;
}
else
this.Fields = new List<SubscriberFieldModel>();
}
}
和我想设置在元中的所有字段
属性
and I want to set the Metadata in all Fields
property
在换句话说,这个字段
从数据库填充,可以有几种类型,可以是一个字符串
,数量
,下拉菜单
,等...有点像MailChimp字段属性:
In other words, this Fields
are filled up from the Database and can have several types, can be a string
, number
, dropdown
, etc ... kinda like MailChimp Fields Properties:
是有办法做到这一点programmaticaly 或我需要建立一个jQuery插件来验证它,并停止使用使用验证的MVC2?
is there a way to do this programmaticaly or I need to create a jQuery plugin to validate it and stop using use validation from MVC2 ?
感谢您
推荐答案
我不认为你可以做到这一点使用数据注释属性。
I dont think you can do this using Data Annotations attributes.
有在codePLEX一个项目,叫允许您添加使用的.Net code能说一口流利的方式验证规则。我从来没有使用过该项目,但似乎,也许可以帮助你在你的情况与动态创建的对象。
There is a project in Codeplex, called Fluent Validation that permit you to add validation rules in a fluent way using .Net code. I never used that project but it seems that maybe can help you in your case with dynamically created objects.
希望它帮助!
