我将我的应用程序从.Net Core 1.1,EF Core 1.1,ASP.Net Identity 1.1迁移到所有版本2.1。我还从IdentityUser中分离了自己的用户(当前称为Diver),因此不需要为ASP.Net Idenentity-EF提供自定义用户类。

当我现在尝试使用以下方法添加初始迁移时:

dotnet ef migrations add initial -s . -p ../Tauchbolde.Common/

我得到了错误:

The entity type 'IdentityUserLogin<int>' requires a primary key to be defined.

我的上下文如下:

public class ApplicationDbContext : IdentityDbContext
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
    : base(options)
    { }

    public DbSet<Event> Events { get; set; }
    public DbSet<Participant> Participants { get; set; }
    public DbSet<Comment> Comments { get; set; }
    public DbSet<Diver> Diver { get; set; }
    public DbSet<Notification> Notifications { get; set; }
    public DbSet<Post> Posts { get; set; }
    public DbSet<PostImage> PostImages { get; set; }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        // ApplicationUser
        builder.Entity<Diver>()
            .HasMany(e => e.Notificationses)
            .WithOne(e => e.Recipient)
            .OnDelete(DeleteBehavior.Restrict);
        builder.Entity<Diver>()
            .HasMany(e => e.Comments)
            .WithOne(e => e.Author)
            .OnDelete(DeleteBehavior.Restrict);
        builder.Entity<Diver>()
            .HasMany(e => e.Events)
            .WithOne(e => e.Organisator)
            .OnDelete(DeleteBehavior.Restrict);
        builder.Entity<Diver>()
            .HasMany(e => e.Posts)
            .WithOne(e => e.Author)
            .OnDelete(DeleteBehavior.Restrict);
        builder.Entity<Diver>()
            .HasMany(e => e.Claims)
            .WithOne()
            .HasForeignKey(e => e.UserId)
            .IsRequired()
            .OnDelete(DeleteBehavior.Cascade);
        builder.Entity<Diver>()
            .HasMany(e => e.Logins)
            .WithOne()
            .HasForeignKey(e => e.UserId)
            .IsRequired()
            .OnDelete(DeleteBehavior.Cascade);
        builder.Entity<Diver>()
            .HasMany(e => e.Roles)
            .WithOne()
            .HasForeignKey(e => e.UserId)
            .IsRequired()
            .OnDelete(DeleteBehavior.Cascade);

        // Comment
        builder.Entity<Comment>().HasOne(e => e.Event).WithMany(e => e.Comments).OnDelete(DeleteBehavior.Restrict);

        // Event
        builder.Entity<Event>().HasIndex(p => new { p.StartTime, p.Deleted });
        builder.Entity<Event>().Property(e => e.Deleted).HasDefaultValue(false);
        builder.Entity<Event>().Property(e => e.Canceled).HasDefaultValue(false);

        // Notification
        builder.Entity<Notification>().Property(e => e.AlreadySent).HasDefaultValue(false);
        builder.Entity<Notification>().Property(e => e.CountOfTries).HasDefaultValue(0);

        // Participants
        builder.Entity<Participant>().HasOne(e => e.Event).WithMany(e => e.Participants).OnDelete(DeleteBehavior.Restrict);
        builder.Entity<Participant>().Property(e => e.CountPeople).HasDefaultValue(1);

        // Post
        builder.Entity<Post>().HasIndex(p => new { p.Category, p.PublishDate });

        // PostImage

        // UserInfo
        builder.Entity<Diver>().Property(e => e.NotificationIntervalInHours).HasDefaultValue(1);
    }

我已经尝试了很多事情,例如为Identity实体添加ignore语句。什么都没做,我被困住了。

有什么想法会出问题吗?

我不确定,但是尝试用此替换您的第一行:

public class ApplicationDbContext : IdentityDbContext<IdentityUser>

似乎我的实体与ASP.Net Identity实体之间存在一些关系。切换到继承的Identity用户实体时,似乎没有清理它们。我还向DBContext添加了两个构造函数,它们不使用通用参数,而是使用默认参数。这已经解决了我现在可以通过问题中显示的推荐添加迁移的方式。
