Asp.net mvc inheritance controllers

I'm studing asp.net mvc and in my test project I have some problems with inheritance: In my model I use inheritanse in few entities:

public class Employee:Entity
    {
        /* few public properties */
    }

It is the base class. And descendants:

public class RecruitmentOfficeEmployee: Employee
    {
        public virtual RecruitmentOffice AssignedOnRecruitmentOffice { get; set; }
    }

public class ResearchInstituteEmployee: Employee
    {
        public virtual ResearchInstitute AssignedOnResearchInstitute { get; set; }
    }

I want to implement a simple CRUD operations to every descedant.

What is the better way to inplement controllers and views in descendants: - One controller per every descendant; - Controller inheritance;

- Generic controlle开发者_如何学Cr; - Generic methods in one controller.

Or maybe there is an another way?

My ORM is NHibernate, I have a generic base repository and every repository is its descedant. Using generic controller, I think, is the best way, but in it I will use only generic base repository and extensibility of the system will be not very good.

Please, help the newbie)

It really depends on how much shared logic there is and how your want your application to flow.

If most of the logic is the same, I would say reuse a single controller and create views that match each inherited type. You would load the appropriate repository, domain objects, and view depending on the type. The type could be determined by a parameter, routing, or some other lookup determined in an action filter.

Here's an example of doing it by passing in a parameter (the easiest technique IMO):

public class EmployeeController : Controller
{
    public enum EmployeeType
    {
        RecruitmentOffice,
        ResearchInstitute
    }

    public ActionResult Details(int id, EmployeeType type)
    {            
        switch (type)
        {
            case EmployeeType.RecruitmentOffice:
                // load repository
                // load domain object
                // load view specific to recruitment office
                break;
            case EmployeeType.ResearchInstitute:
                // load repository
                // load domain object
                // load view specific to recruitment office
                break;
        }
    }
}
