Well, I have this DB Model "Book"
public class Book {
public int Id { get; set; }
public string Title { get; set; }
public string Author { get; set; }
public bool IsSubmitted { get; set; }
public bool IsCompleted { get; set; }
public bool IsDeleted { get; set; }
}
And I have implemented repository pattern where my GetBook(int id) method returns a Book which looks like this:
public Book GetBook(int id) {
return db.Books.Find(id);
}
However, my BookViewModel needs to query some other things as well. It looks like this:
public class BookViewModel
{
public int Id { get; set; }
public string Title { get; set; }
public string AuthorName { get; set; }
public int CommentsCount { get; set; }
public int FeedbacksCount { get; set; }
public int ViewsCount { get; set; }
}
Currently, my service layer is mapping binding models to DB models and passing them to repository.
Now my question is where should I query this additional (view-specific) data? Should I write separate repository methods for CommentsCount, FeedbacksCount, ViewsCount etc. and call them from my service layer to prepare my view model or should I write a new repository method with return type BookViewModel where I query all the required data in a single query?
Any help is highly appreciated.
