如何首先使用代码在已创建的数据库中创建ASP.net身份表？

Question

我的应用程序已经开发了大约一个月.我现在决定使用ASP.NET Identity.我已经拥有了身份的视图模型,但需要创建表.我在想,如果我有视图模型,我不确定为什么我没有表？我使用自己的自定义上下文在初始化程序中删除了create,我只需要知道如何让EF为用户和角色构建包含的Identity表？我环顾四周,所发布的答案似乎都不是我所需要的？

Answer 1

考虑迁移

如果适用,您需要考虑构建迁移,这将允许您生成(并可能执行)必要的脚本,以在数据库中创建适当的表或更改.

默认情况下,您应该有一些ApplicationDbContext类似于以下类的类,它们将用于定义"安全相关"数据库:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection", false)
    {
    }

    // Other code omitted for brevity
}

然后,您只需要在程序包管理器控制台中运行Enable-Migrations命令:

Enable-Migrations

这应该在您的应用程序中生成一个Migrations文件夹,其中包含控制迁移的执行方式和迁移方式的各种配置文件InitialCreate.如果您之前在应用程序中有一些与Code-First相关的代码,则可能只会出现这种情况,如果没有,请不要担心.然后,您可以尝试运行Update-Database命令,该命令应对您的数据库执行任何迁移(包括初始迁移):

Update-Database

更新数据库后,您可以继续对模型进行更改,只需通过Add-Migration命令和以前的Update-Database命令创建和执行新的迁移:

Add-Migration "AddedAnotherPropertyToFoo"
Update-Database

Answer 2

因此，经过一番摆弄后，我得到了答案。最后，我要做的只是从ASP.NET Identity运行register方法，并创建了所有表。

在您的数据库上运行此SQL脚本并完成它。
