Reading foreign key data in Entity Framework












0














I have two model classes, Chefs and Dishes. It is a 1-to-many relationship. One chef can make many dishes, but each dish can only be made by one chef. These are my model classes:



public class Chef
{
[Key]
public int ChefId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DoB { get; set; }
public List<Dish> Dishes { get; set; }
}

public class Dish
{
[Key]
public int DishId { get; set; }
public string DishName { get; set; }
public int Calories { get; set; }
public int Tastiness { get; set; }
public string Description { get; set; }
public int ChefId { get; set; }
public Chef Creator { get; set; }
}


When I click the dishes page, I am trying to display all the dishes with the name of the Chef who made that dish.



If I query like this:



var dishes = _context.Dishes.ToList (); 


I am only able to access the Id of the Chef, not the name.



I have also tried this:



var dishes = _context.Dishes.Include(c => c.Creator).ToList();


If I do that, Creator is the entire Chef object, and if I try to loop through it, I get errors as well. Can someone please get me in the right direction?



Thanks

  • @foreach (Dish dish in @ViewBag.dishes) { <tr> <td>@dish.DishName</td> <td>@dish.ChefId</td> <td>@dish.Tastiness</td> <td>@dish.Calories</td> <td>@dish.Creator</td> </tr> }
