[英]ASP.NET Core MVC - User Tables not being created when applying database migrations
我有一个 Asp.net Core MVC 项目，执行以下命令时没有在数据库中创建用户表：
Add-Migration migrationName
Update-Database
它将更新我的模型链接到的表，但不会添加用户表。 这是一个问题，因为我想使用 ASP.NET Core MVC 框架提供的登录功能，我认为这些表应该在应用迁移时自动填充数据库。
有谁知道为什么在通过 nugget 包管理器控制台更新我的数据库时这不会自动发生？ 这是我从 github 获得的一个朋友的项目，我需要处理它，我不确定要检查什么以确保他们正确配置了这个项目，以便自动创建用户表。
如何配置我的项目以自动添加用户表？
任何帮助将不胜感激 - 我已经看过以前的堆栈溢出答案，但大多数已经过时了。
编辑：数据库中的迁移表确实包括我应用于数据库的 userTest 迁移。 这里也是在 MVC 项目中创建的迁移文件，如果有帮助的话。：
using Microsoft.EntityFrameworkCore.Migrations;
namespace SEWebPage03.Migrations
{
public partial class userTest : Migration
{
protected override void Up(MigrationBuilder migrationBuilder)
{
}
protected override void Down(MigrationBuilder migrationBuilder)
{
}
}
}
如果您在创建项目时选择了No Authentication ...您将需要手动搭建身份框架。
这是可以做到的……它需要几个步骤。
首先是修改ApplicationDbContext.cs
改变这一行
public class ApplicationDbContext: DbContext {}
对此
public class ApplicationDbContext: IdentityDbContext {}
您将需要安装这些 Nuget 包。
Microsoft.AspNetCore.Identity.EntityFrameworkCore
Microsoft.AspNetCore.Identity.UI
Next Change StartUp.cs
在ConfigureServices
添加：
services.AddDefaultIdentity<IdentityUser>()
.AddEntityFrameworkStores<ApplicationDbContext>();
使用它来添加角色
services.AddIdentity<IdentityUser,IdentityRole>()
.AddDefaultTokenProviders().AddDefaultUI()
.AddEntityFrameworkStores<ApplicationDbContext>();
现在在 StartUp.cs 中进一步向下滚动到 Configure 方法。
在app.UseAuthorization()之前添加app.UseAuthentication();
重要..它需要按照这个顺序。
app.UseAuthentication();
app.UseAuthorization();
现在你添加一个新的迁移
PM->add-migration scaffoldIdentity
PM->更新数据库
身份迁移
