Question

我一直在使用ASP.NET Web表单和个人身份验证设置来开发项目，该设置使用实体框架在表AspNetUsers上创建用户。

因此，我创建了一个名为Department的新类，该类具有一个deptId作为主键。我尝试修改IdentityModels.cs代码以将deptId添加为AspNetUsers中的外键。

下面的代码是我为尝试实现外键而添加的。

public class ApplicationUser : IdentityUser
{
    public ICollection<ApplicationUser> ApplicationUsers { get; set; }

    public string isVerified { get; set; }

    // Foreign key to customer
    [ForeignKey("Department")]
    public int deptId { get; set; }

    public virtual Department Department { get; set; }

    public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);

         // Add custom user claims here
         return userIdentity;
    }

    public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
    {
        return Task.FromResult(GenerateUserIdentity(manager));
    }
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public DbSet<Post> Posts { get; set; }
    public DbSet<Comment> Comments { get; set; }    
    public DbSet<Department> Departments { get; set; }

    public ApplicationDbContext()
        : base("DefaultConnection", throwIfV1Schema: false)
    {
    }

    public object User { get; internal set; }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

然后尝试从该行注册时出现以下错误

 IdentityResult result = manager.Create(user, Password.Text);

错误如下

SqlException：INSERT语句与FOREIGN KEY冲突约束“ FK_dbo.AspNetUsers_dbo.Departments_deptId”。冲突表中发生在数据库“ aspnet-WebEnterprise-20190201040106”中 “ dbo.Departments”列“ deptId”。该声明已终止。

我正在做的任何明显错误或遗漏的原因都导致了吗？

asp.net实体框架“插入”语句与FOREIGN键约束冲突
