如何更改asp.net標識3（vnext）使用的表名稱？

Question

在asp.net身份2來改變身份的表名的方法並不在asp.net身份3.

Answer 1

工作修改您的ApplicationDbContext的OnModelCreating建設者實體，使用ForSqlServerToTable擴展方法來改變所需的表（s）的名字。

public class ApplicationDbContext : IdentityDbContext<ApplicationUser> 
    { 
     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>().ForSqlServerToTable("Users"); 
      builder.Entity<IdentityUserRole<string>>().ForSqlServerToTable("UserRoles"); 
      builder.Entity<IdentityUserLogin<string>>().ForSqlServerToTable("UserLogins"); 
      builder.Entity<IdentityUserClaim<string>>().ForSqlServerToTable("UserClaims"); 
      builder.Entity<IdentityRole>().ForSqlServerToTable("Roles");       
     } 
    } 

Answer 2

你可以通過你的DbContext的OnModelCreating改變與擴展方法ToTable("TableName")實體映射做到這一點很容易：

而你並不需要使用.ForSqlServerToTable()，只是.ToTable()應該在任何數據庫。

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

    builder.Entity<User>().ToTable("Users"); // Your custom IdentityUser class 
    builder.Entity<IdentityUserLogin<string>>().ToTable("UserLogins"); 
    builder.Entity<IdentityUserToken<string>>().ToTable("UserTokens"); 
    builder.Entity<IdentityUserClaim<string>>().ToTable("UserClaims"); 
    builder.Entity<IdentityUserRole<string>>().ToTable("UserRoles"); 
    builder.Entity<IdentityRoleClaim<string>>().ToTable("RoleClaims"); 
    builder.Entity<IdentityRole>().ToTable("Roles");    
} 

這裏，唯一的缺點是要記住與您的標識符的類型使用泛型（字符串是默認的AspNetCore。
