我正在使用ASP.NET MVC4和Entity Framework 5.
基本上每个控制器操作结果都按登录的用户公司ID过滤数据库结果.我刚刚开始实现一个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,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良做法的信息,以及为什么如此.
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()); } }
谢谢你提前帮助:)
