如何更改.NET CORE中的默認ASP.NET標識表名稱？

Question

我已經開始與.NET的核心，在MVC 5我改變例如默認的表名：以這種方式AspNETUsers給用戶它完美地工作： 在IdentityModels I類dded：

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

     modelBuilder.Entity<IdentityUser>().ToTable("Users").Property(p => p.Id).HasColumnName("UserId"); 
     modelBuilder.Entity<ApplicationUser>().ToTable("Users").Property(p => p.Id).HasColumnName("UserId"); 
     modelBuilder.Entity<IdentityUserRole>().ToTable("UserRoles"); 
     modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins"); 
     modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims"); 
     modelBuilder.Entity<IdentityRole>().ToTable("Roles"); 
    } 

但它在.NET CORE（MVC 6）中不起作用。 任何人都可以幫助我嗎？ 非常感謝。

Answer 1

嘗試改變結合

builder.Entity<ApplicationUser>(entity => 
     { 
      entity.ToTable(name:"Users"); 
      entity.Property(e => e.Id).HasColumnName("UserId"); 

     });

- 要改變這些表（IdentityUserRole <Tkey>，IdentityUserToken <Tkey>，IdentityRoleClaim <Tkey>，IdentityUserClaim <Tkey>，IdentityUserLogin <Tkey>）的名字，你必須指定TKEY的類型（的用於主鍵的類型），即使沒有更改，也是默認字符串（GUID）。

- 如果你想改變GUID主鍵爲int https://medium.com/@goodealsnow/asp-net-core-identity-3-0-6018fc151b4

protected override void OnModelCreating(ModelBuilder builder) 
    { 
     base.OnModelCreating(builder); 
     // Customize the ASP.NET Identity model and override the defaults if needed. 
     // For example, you can rename the ASP.NET Identity table names and more. 
     // Add your customizations after calling base.OnModelCreating(builder); 

     builder.Entity<ApplicationUser>(entity => 
     { 
      entity.ToTable(name: "User");   
     }); 

     builder.Entity<IdentityRole>(entity => 
     { 
      entity.ToTable(name: "Role"); 
     }); 
     builder.Entity<IdentityUserRole<string>>(entity => 
     { 
      entity.ToTable("UserRoles"); 
      //in case you chagned the TKey type 
      // entity.HasKey(key => new { key.UserId, key.RoleId }); 
     }); 

     builder.Entity<IdentityUserClaim<string>>(entity => 
     { 
      entity.ToTable("UserClaims"); 
     }); 

     builder.Entity<IdentityUserLogin<string>>(entity => 
     { 
      entity.ToTable("UserLogins"); 
      //in case you chagned the TKey type 
      // entity.HasKey(key => new { key.ProviderKey, key.LoginProvider });  
}); 

     builder.Entity<IdentityRoleClaim<string>>(entity => 
     { 
      entity.ToTable("RoleClaims"); 

     }); 

     builder.Entity<IdentityUserToken<string>>(entity => 
     { 
      entity.ToTable("UserTokens"); 
      //in case you chagned the TKey type 
      // entity.HasKey(key => new { key.UserId, key.LoginProvider, key.Name }); 

     }); 
    }
