实体框架种子与身份（Microsoft.Owin.Security）用户-Java 学习之路

我有一个为数据库设置种子的类，它为2个用户添加了角色和自定义字段 . 我遇到的问题是它将数据保存在[dbo] . [AspNetUsers]而不是[dbo] . [IdentityUsers] . 两个表都已创建 . 播种时，数据进入AspNetUser . 当我启动网站并注册新用户时，数据将进入IdentityUser .

这是Migration类：

internal sealed class Configuration : DbMigrationsConfiguration<DatabaseContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }

    protected override void Seed(DatabaseContext context)
    {
        base.Seed(context);

        var userStore = new UserStore<ApplicationUser>();
        var manager = new UserManager<ApplicationUser>(userStore);

        var role = new IdentityUserRole { Role = new IdentityRole(Model.Roles.ADMINISTRATOR) };
        var user = new ApplicationUser() { UserName = "123123", Email = "123123@123.com", Language = "en-US"};
        user.Roles.Add(role);
        IdentityResult result = manager.Create(user, "123123");

        var role2 = new IdentityUserRole { Role = new IdentityRole(Model.Roles.NORMAL) };
        var user2 = new ApplicationUser() { UserName = "qweqwe", Email = "qweqwe@qweqwe.com", Language = "fr-CA" };
        user.Roles.Add(role2);
        IdentityResult result2 = manager.Create(user2, "qweqwe");
    }
}

以下是ApplicationUser类，它定义Identity模型的自定义字段 .

public class ApplicationUser : IdentityUser, ICurrentUser
{
    public ApplicationUser()
    {
        Email = "";
        Language = "";
    }
    public string UserId {
        get { return base.Id; }
        set{} 
    }
    public string Email { get; set; } 
    public string Language { get; set; } 

}

以下是此新类的Entity Framework配置类 .

public class ApplicationUserConfiguration : EntityTypeConfiguration<ApplicationUser>
{
    public ApplicationUserConfiguration()
    {
        this.HasKey(d => d.Id);
        this.Ignore(d => d.UserId);
    }
}

enter image description here

两者都使用具有相同配置的save DataContext：

protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        //... others entity here

        modelBuilder.Configurations.Add(new ApplicationUserConfiguration());

        //Theses configuration are required since custom fields are added to ApplicationUser. Here is why : http://stackoverflow.com/questions/19474662/map-tables-using-fluent-api-in-asp-net-mvc5-ef6
        modelBuilder.Entity<IdentityUserLogin>().HasKey(l => l.UserId);
        modelBuilder.Entity<IdentityRole>().HasKey(r => r.Id);
        modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId, r.UserId });

    }

我的问题是：为什么我有从Identity表复制的AspNet前缀表名？为什么种子在Web应用程序使用另一种时使用一种？

您的DbContext是否继承自IdentityDbContext？

如果从IdentityDbContext继承，则不需要在OnModelCreating中进行任何其他配置 . IdentityDbContext提供的映射和默认的实体框架约定应该足够了 .

如果在没有UserId的setter的情况下声明ApplicationUser，则不需要忽略UserId属性：
```
public class ApplicationUser : IdentityUser
{
    public ApplicationUser()
    {
        Email = "";
        Language = "";
    }

    public string Email { get; set; }
    public string Language { get; set; }

    public string UserId
    {
        get { return Id; }
    }
}
```
然后你的ApplicationDbContext可以这么简单（为了清楚起见，我已将Configuration类重命名为MigrationConfiguration）：
```
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    static ApplicationDbContext()
    {
        Database.SetInitializer(new MigrateDatabaseToLatestVersion<ApplicationDbContext, MigrationConfiguration>());
    }

    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }
}
```
这与AspNet.Identity.Core和AspNet.Identity.EntityFramework程序集的发行版本（版本1.0.0）一样按预期工作（只有名为AspNetXXXX的表，AspNetUsers表具有自定义字段） .
