Question

我的申请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，似乎找不到所需的答案？

Answer 1

考虑迁移

如果适用，您需要考虑构建migration，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，您应该使用某种类型的ApplicationDbContext类，其类似于以下内容，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，您只需在Package Manager控制台中运行启用 - 迁移命令：

Enable-Migrations

这应该在您的应用程序中生成一个Migrations文件夹，其中包含控制迁移方式以及InitialCreate迁移的各种配置文件。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，只需通过添加 - 迁移命令和以前的Update-Database命令创建和执行新的迁移：

Add-Migration "AddedAnotherPropertyToFoo"
Update-Database

Answer 2

在您的数据库上运行此SQL脚本并完成它。

Answer 3

所以经过一番阅读后，我得到了答案。我所要做的就是终于从ASP.NET Identity运行register方法，并创建了所有表。

Answer 4

如果您不想启用迁移，可能只是针对数据库运行ASP.NET Identity Sql脚本：

如何首先使用代码在已创建的数据库中创建ASP.net身份表？
