我的模型上有两个相关的类。

该模型的表格如下
public class Project
{
public virtual int Id { get; set;}
public virtual AdUser Creator { get; set; }
}
public class AdUser
{
public virtual string Id { get; set; }
public List<string> Groups { get; set; }
}
CREATE TABLE [dbo].[Projects] (
[Id] INT IDENTITY (1, 1) NOT NULL,
[CreatorId] VARCHAR(100) NOT NULL,
CONSTRAINT [PK_Projects] PRIMARY KEY CLUSTERED ([Id] ASC)
);
类的数据源不是数据库,因为它代表Active Directory用户。因此,我想在上下文中调用AdUser
后,只能在CreatorId
列上存储Creator.Id属性。
另一方面,如果我从数据库中获取了一个项目,我只想要一个空SaveChanges()
来设置Creator
。
主要思想是访问由独立存储库处理的Id
数据。
我定位到Entity Framework 6.0

听起来好像要使用[NotMapped]属性
public class Project
{
public virtual int Id { get; set;}
public virtual string CreatorId { get; set; }
[NotMapped]
public virtual AdUser Creator { get; set; }
}
这将告诉EF忽略模型上的Creator属性。
在我看来,你应该在这里为你的数据和应用程序逻辑使用不同的模型,例如,如果你想让一个不同的业务逻辑填充一个Creator,让它返回一个新的对象,不要把它放在datatier模型中。这个IMO更好地遵循SRP,即模型要么用于存储,要么不应用于两者。

你可以将一个AdUserId映射到CreatorId私有(对于类消费者来说是一个很好的方法)并明确地映射项目。
public class Project
{
public virtual int Id { get; set;}
private string AdUserId {
get { // Read from AdUser
}
set { // set a backing field for
// AdUser lazy load or just set AdUser in an
// eagerly load approach
}
// virtual is not required any more
// If you need insert backing field for lazy load
public AdUser Creator { get ; set; }
public ProjectMap : EntityTypeConfiguration<Project>
{
public ProjectMap()
{
Ignore(t => t.AdUser);
Property(t => t.AdUserId).HasColumnName("CreatorId");
}
}
}
public class AdUser
{
public virtual string Id { get; set; }
public List<string> { get; set; }
}
在上下文课程中
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Configurations.Add(new Project.ProjectMap());
}
