EF7 身份自定义 table 名称第一种子

Question

我已经创建了一个新的干净的 asp.net 5 项目 (rc1-final)，我只需要更改默认的 ef 身份 table 名称。

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    protected override void OnModelCreating(ModelBuilder builder)
    {
        // On event model creating
        base.OnModelCreating(builder);

        // Define table name
        builder.Entity<IdentityUser>().ToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");
        builder.Entity<ApplicationUser>().ToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");
        builder.Entity<IdentityUserRole<string>>().ToTable("BackEnd_AspNetUserRoles");
        builder.Entity<IdentityUserLogin<string>>().ToTable("BackEnd_AspNetUserLogins");
        builder.Entity<IdentityUserClaim<string>>().ToTable("BackEnd_AspNetUserClaims");
        builder.Entity<IdentityRole>().ToTable("BackEnd_AspNetRoles");
    }
}

我收到以下错误

InvalidOperationException: Cannot use table 'BackEnd_AspNetUsers' in schema '' for entity 'ApplicationUser' since it is being used for another entity.

Answer 1

此处的这些行表明您正在尝试为基本标识 类 和您的应用程序的继承版本设置映射 类;

builder.Entity<IdentityUser>().ToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");
builder.Entity<ApplicationUser>().ToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");

你不需要两者，你应该只指定继承的一个 - ApplicationUser。

Answer 2

在您的情况下，您应该使用 ForSqlServerToTable("newtablename")

builder.Entity<IdentityUser>().ForSqlServerToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");
builder.Entity<ApplicationUser>().ForSqlServerToTable("BackEnd_AspNetUsers").Property(p => p.Id).HasColumnName("UserId");
