Hello, I have a question regarding the following situation: I have an Entity that I defined in my model as TaskFreq
public partial class TarefaFreq
{
[Key]
public int ID { get; set; }
public string Name { get; set; }
}
I created some data in a static list:
public class TarefaFreqData
{
public static IEnumerable<TarefaFreq> GetLista()
{
var list = new List<TarefaFreq>();
list.Add(new TarefaFreq() { ID = 1, Name = "Teste 1" });
list.Add(new TarefaFreq() { ID = 2, Name = "Teste 2" });
return list;
}
}
And I also have the Task model (This one is in the database):
public partial class Tarefa
{
public int ID { get; set; }
public int FreqID { get; set; }
public virtual TarefaFreq Freq { get; set; }
}
In my webAPI settings with Entity-Framework if I try to set my property:
builder.EntityType<Tarefa>().Property(f => f.Freq);
I get the following error:
The type TarefaFreq must be a non-nullable value type in order to use it ...
My goal is that when I enter in the URL:
http://localhost:58170/odata/Tarefas(12)/?$expand=Freq
I can get the data in the response.
Remembering that TaskFreq Entity will not be in my database, it was only created to serve data to a foreign key that is in my database which is the property of Tarefa - > FreqID , so the static list I created. In this case, as I'm developing in the client I need to use the $expand of ASP.NET Web API 2 OData.
