Entity Framework 核心加入身份 AspNetUser table。自定义的 AspNetUser Id tables/Entities

Question

我启动了一个新的 Blazor 应用程序，我正在尝试使用 Entity FrameworkCore。我想 link Identity AspNetUsers table。我想要与 UserAddress Table 的一对多关系。一个 AspNetUser 有多个地址。

 public class UserAddress
   {
    public string Id { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string ZipCode { get; set; }
    ' I don't know what to put here to connect this table with the AspNetUsers Table
      public int UserId {get;set} This doesn't work 
    }

我不知道如何让 EF 构造 AspNetUsers Id 和 UserAddress 之间的一对多关系 table

Answer 1

您可以像这样创建 one-to-many 关系。

用户地址class:

public class UserAddress
{
    public string Id { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string ZipCode { get; set; }

}

新的ApplicationUser继承Identityuser：

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

在您的 ApplicationDbContext 中进行如下更改：

 public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        builder.Entity<ApplicationUser>(b => { b.HasMany(p => p.UserAddresses); }) ;
    }
    public DbSet<UserAddress> UserAddresses { get; set; }
}

然后开始迁移并更新数据库。

结果：

Entity Framework 核心加入身份 AspNetUser table。自定义的 AspNetUser Id tables/Entities

Entity Framework Core Join identity AspNetUser table. AspNetUser Id to custom tables/Entities

asp.net

entity-framework

asp.net-identity

entity-framework-core

asp.net-core
