Question

Build ViewModel using two models

Model 1: Person (Id,Name,Address,Phone,CategoryId)

Model 2: Category(CategoryId,CategoryText)

ViewModel: PersonViewModel (Name,Phone, CategoryText)

Question: how would I generate my ViewModel in my controller and forward it to the view:

 var model = (from x in db.Person 
             select new PersonViewModel { 
                    Name = x.Name, 
                    Phone = x.Phone, 
                    CategoryText = ??? }).ToList(); 

How do I generate CategoryText?

Thanks

Answer 1

You need to join on categories.
you may be able to include as the following, if not you just need a join. Try the following (I forget if you can include() in this syntax – somethingin my mind tells me you can’t and if that’s the case I’ll delete this shortly as I see someone just posted the join syntax)

var model = (from x in db.Person.Include(o=>o.Category) //assumes EF 4.1 if not try .Include("Category")
             select new PersonViewModel { 
                    Name = x.Name, 
                    Phone = x.Phone, 
                    CategoryText = x.Category.CategoryText }).ToList();
