【问题描述】:
我正在使用带有 Entity Framework 5 的 ASP.NET MVC4。
基本上每个控制器操作结果通过登录的用户的公司 ID 过滤数据库结果。我刚刚开始实现存储库模式来返回模型,而不是直接从控制器中过滤 DbContext。 (将 companyID 传递到存储库以过滤方法的结果)
我有一种有趣的感觉,即这样做是不好的做法,但一直无法找到有关该主题的任何信息。我将在下面插入我当前代码的基本版本,我将不胜感激任何关于它是否是不好的做法以及为什么会这样的信息。
IBookingSystemRepository.cs
public interface IBookingSystemRepository : IDisposable
{
IEnumerable<Appointment> GetAppointments();
IEnumerable<Appointment> GetAppointments(bool includeDeleted);
IEnumerable<Client> GetClients();
IEnumerable<Client> GetClients(bool includeDeleted);
void Save();
}
BookingSystemRepository.cs
public class BookingSystemRepository : IBookingSystemRepository
{
private BookingSystemEntities db;
int CompanyID;
public BookingSystemRepository(BookingSystemEntities context, int companyID)
{
this.db = context;
this.CompanyID = companyID;
}
public IEnumerable<Appointment> GetAppointments()
{ return GetAppointments(false); }
public IEnumerable<Appointment> GetAppointments(bool includeDeleted)
{
return includeDeleted
? db.Appointments.Where(a => a.User.CompanyID == CompanyID)
: db.Appointments.Where(a => a.User.CompanyID == CompanyID && a.Deleted.HasValue);
}
public IEnumerable<Client> GetClients()
{ return GetClients(false); }
public IEnumerable<Client> GetClients(bool includeDeleted)
{
return includeDeleted
? db.Clients.Where(c => c.CompanyID == CompanyID)
: db.Clients.Where(c => c.CompanyID == CompanyID && c.Deleted.HasValue);
}
public void Save()
{
db.SaveChanges();
}
public void Dispose()
{
if (db != null)
db.Dispose();
}
}
TestController.cs
public class TestController : Controller
{
private BookingSystemEntities db = new BookingSystemEntities();
public ActionResult AppointmentsList()
{
var user = db.Users.Single(u => u.Email == User.Identity.Name);
IBookingSystemRepository rep = new BookingSystemRepository(db, user.CompanyID);
return View(rep.GetAppointments());
}
}
提前感谢您的帮助:)
