I am learning to apply DIC to MVC project. So, I have sketched this DDD-ish DIC-ready-ish layout to my best understanding. I have read many blogs articles wikis for the last few days. However, I am not confident about implementing it correctly. Could you please demonstrate to me how to put them into DIC the proper way? I prefer Ninject or Windsor after all the readings, but anyDIC will do as long as I can get the correct idea how to do it.
Web controller...
public class AccountBriefingController {
//create
private IAccountServices accountServices { get; set; }
public AccountBriefingController(IAccountServices accsrv)
accountServices = accsrv;
}
//do work
public ActionResult AccountBriefing(string userid, int days) {
//get days of transaction records for this user
BriefingViewModel model = AccountServices.GetBriefing(userid, days);
return View(model);
}
}
View model ...
public class BriefingViewModel {
//from user repository
public string UserId { get; set; }
public string AccountNumber {get; set;}
public string FirstName { get; set; }
public string LastName { get; set; }
//from account repository
public string Credits { get; set; }
public List<string> Transactions { get; set; }
}
Service layer ...
public interface IAccountServices {
BriefingViewModel GetBriefing();
}
public class AccountServices {
//create
private IUserRepository userRepo {get; set;}
private IAccountRepository accRepo {get; set;}
public AccountServices(UserRepository ur, AccountRepository ar) {
userRepo = ur;
accRepo = ar;
}
//do work
public BriefingViewModel GetBriefing(string userid, int days) {
var model = new BriefingViewModel(); //<---is that okay to new a model here??
var user = userRepo.GetUser(userid);
if(user != null) {
model.UserId = userid;
model.AccountNumber = user.AccountNumber;
model.FirstName = user.FirstName;
model.LastName = user.LastName;
//account records
model.Credits = accRepo.GetUserCredits(userid);
model.Transactions = accRepo.GetUserTransactions(userid, days);
}
return model;
}
}
Domain layer and data models...
public interface IUserRepository {
UserDataModel GetUser(userid);
}
public interface IAccountRepository {
List<string> GetUserTransactions(userid, days);
int GetUserCredits(userid);
}
// Entity Framework DBContext goes under here
Please point out if my implementation is wrong, e.g.I can feel in AccountServices-GetBriefing - new BriefingViewModel() seems wrong to me, but I don't know how to fit the stud into DIC?
Thank you very much for your help!
