ASP.NET MVC5实体框架应用程序中的单个上下文

Question

As demonstrated in my last question here: "Define the key for this EntityType." when including attribute of type ApplicationUser

I need to use a single database context, whereas my current setup is one context (defined within IdentityModel.cs) for the login stuff and another context (defined externally) for all other database operations in the application.

How would I go about using a single context? I do not care about existing data.

Answer 1

You can certainly use single context.

Below is what i did:

public class DataContext :  IdentityDbContext<ApplicationUser> 
{
    public DataContext()
        : base("DefaultConnection")
    {

    }

    public IDbSet<Project> Projects { set; get; }
    public IDbSet<Task> Tasks { set; get; }
}

Then in account controller:

public class AccountController : Controller
{
    public AccountController()
        : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new DataContext())))
    {
    }

when you create a new project:

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

you get this which doesnt have much information, you can use this as well and add your dbsets. It has a reference from AccountController.

只是将用于ASP.NET Identity的数据上下文子类化。
