Asp.NET MVC Product> ProductPhoto - asp.net-mvc

Question

I have 2 Separate Tables Products and Product Photo
When I examine any details in the products table, I want the pictures of that product to come. In that case, I pull it into the Detail table in a field called _UrunFotoPartitialView as # html.partitial ("") but always
The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Urun_C7B3883A1159F8EE0177C29B1CA535182B157B3C5BB798ABCC8C2A72FB5CFED9', but this dictionary requires a model item of type 'Tututuncu.Models.UrunFotoViewModel'.
gives an error. How many days I have been dealing but I couldn't do it.

Answer 1

You have two model types.
Parent: #model IEnumerable<Tututuncu.Models.Urun>
Partial: #model IEnumerable<Tututuncu.Models.UrunFoto>
You're calling Partial using #Html.Partial("FotoListele")
You can use #Html.Partial("FotoListele", THE-NEW-MODEL-OF-LIST-UrunFoto)
When using Partial without passing the new model, it uses the parent model. Thus, it gets exception when trying to perform the casting.
You can either create a new Model that fits the Partial needs, or accept the parent model.
Note: partial class doesn't relate at all to razor engine Html.Partial. more on that Here
