这是我想将它连接到ApplicationUser类的类（从Identity生成的默认类）
public class UserProfile
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public Guid Id { get; set; }
public string Name { get; set; }
[Required]
[ForeignKey("ApplicationUser")]
public string UserId { get; set; }
public ApplicationUser ApplicationUser { get; set; }
}
这是ApplicationUser类：
public class ApplicationUser : IdentityUser
{
public virtual ICollection<Post> UserPosts { get; set; }
[Required]
public string UserProfileId { get; set; }
[ForeignKey("UserProfileId")]
[Required]
public virtual UserProfile UserProfile { get; set; }
//... GenerateUserIdentityAsync() function
}
这是DbContext（它是Identity中的默认值）：
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
public System.Data.Entity.DbSet<Post> Post { get; set; }
public System.Data.Entity.DbSet<UserProfile> UserProfile { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<ApplicationUser>()
.HasRequired(b => b.UserProfile)
.WithRequiredDependent(a => a.ApplicationUser);
base.OnModelCreating(modelBuilder);
}
}
我在OnModelCreating函数中尝试了多种变体但没有很好的结果 . 对于上面的代码，这是我在尝试添加新迁移时遇到的错误：
ApplicationUser_UserProfile_Target: :
Multiplicity is not valid in Role 'ApplicationUser_UserProfile_Target' in relationship
'ApplicationUser_UserProfile'. Because the Dependent Role properties are not the key properties,
the upper bound of the multiplicity of the Dependent Role must be '*'.
我在VS2015中使用ASP.NET MVC5和Entity Framework 6 .
我设法在Users表和自定义类之间设置一对多的关系但是这个我找不到任何正确的解决方案 .
请发送帮助 .
