在WCF RIA服务中使用DataAnnotations（DisplayColumn）
|
我创建了一个实体框架4.0（DB-First）模型，添加了我的部分类，并在它们上使用了“ 0”以在客户端上具有完美的UI。
我的表之间有一些关系，并且在课堂上使用
DisplayColumn
User
[DataColumn(\"UserName\")]
Message
[Include]
DomainService
.Include(\"User\")
DisplayColumn
User
Owner
UserName
MessageId
UserId
UserMeta
[MetadataType(typeof(MessageMeta))]
public partial class Message
{
}
public class MessageMeta
{
[Include()]
[Display(Name = \"Belongs to\", Order = 4)]
[Association(\"Message_User\",\"MessageId\",\"UserId\",IsForeignKey = true)]
public virtual User Owner { get; set; }
}
[MetadataType(typeof(UserMeta))]
[DisplayColumn(\"UserName\")]
public partial class User
{
}
public IQueryable<Message> GetMessages()
{
return this.ObjectContext.Messages.Include(\"Owner\");
}
