合并IdentityDbContext和DbContext ASP.NET MVC [英] Merge IdentityDbContext and DbContext ASP.NET MVC

问题描述

我想在我的ASP.NET MVC项目中只有一个DbContext。我应该如何将默认的IdentityDbContext与我自己的代码优先DbContext合并？他们使用的是同一数据库。

I would like to only have one DbContext in my ASP.NET MVC project. How should I merge the default IdentityDbContext with my own code first DbContext? They are using the same database.

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext()
            : base("SignalRChat")
        {
        }
    }

这是IdentityModel.cs类中提供的默认值。

This is the default one provided in the IdentityModel.cs class.

请执行下列操作？并附加我自己的DbSet？

Is it safe to do the following? And append my own DbSets?

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("SignalRChat")
    {
    }

    public DbSet<Student> Students { get; set; }
    public DbSet<Standard> Standards { get; set; }
}

任何建议都非常感谢！

Any advice is much appreciated!

推荐答案

是的，最好在DbContext类中添加DbSet声明。通常，您可能会为相关的一组表创建一个上下文，当您从存储库中访问它时，例如

Yes, it is perfectly fine to add DbSet declarations in the DbContext classes. Normally you would maybe create a context for a related group of tables that makes sense when you access it from your repositories, e.g. ApplicationDbContext for user registration, login etc. another for Students and related entities.

如果用户有很多上下文，也许应该检查有界上下文模式 https://channel9.msdn.com/Events/TechEd/NorthAmerica / 2013 / DEV-B336＃fbid = wH4n-081m_U 。

If you have many contexts maybe you should check for the bounded context "pattern" https://channel9.msdn.com/Events/TechEd/NorthAmerica/2013/DEV-B336#fbid=wH4n-081m_U.
