我正在使用Identity的标准MVC项目。我希望在ApplicationUser与多个自定义属性的多对多关系中创建一个Friend
表。
我希望桌子看起来像这样:
Friend
----------
UserId ( From ApplicationUser)
FriendID ( From ApplicationUser)
IsApproved ( Bool )
DateCreated ( DateTime )
我知道如何使用2个表制作多对多,但我找不到只用一张表制作它的方法。
有人可以帮忙吗?
编辑:
是的,它是codeFirst。这是我的修改后的标准ApplicationUser类。
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string MiddleName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
public string Phone { get; set; }
public string Mobile { get; set; }
public string Work { get; set; }
public string DisplayName
{
get
{
return this.FirstName + " " + this.LastName;
}
}
public virtual ICollection<Image> Images { get; set; }
public virtual ICollection<Like> Likes { get; set; }
public virtual ICollection<Post> PostFrom { get; set; }
public virtual ICollection<Post> PostTo { get; set; }
public virtual ICollection<Comment> Comments { get; set; }
public virtual ICollection<ApplicationUser> Followers { get; set; }
public virtual ICollection<ApplicationUser> Following { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
}

您可以将DataAnnotations用于您的模型,如下所示:
public class Friend
{
public int User_Id;
[ForeignKey("User_Id")]
public ApplicationUser User;
public int Friend_Id;
[ForeignKey("Friend_Id")]
public ApplicationUser Friend;
public bool IsApproved;
public DateTime DateCreated;
}
