I have a ASP.NET MVC application where in all my Models have an Errors Property used to store non-validation errors which I than display in my Views. Where is the right place to populate the error list according to MVC? Inside the model or inside the controller?

First Option

public class MyModel
{
 public DataOperationResult DoSomething()
  {
   //do something with data
   if (result != DataOperation.Success)
   {
     Errors.Add("Something went wrong");
   }
   return result;       
 }
}

Second option

 public class MyController
  {
   public ActionResult DoSomething()
    {
     MyModel model = new myModel();
     DataOperationResult result = model.DoSomething();
     if (result != DataOperation.Success)
     {
      model.Errors.Add("Something went wrong");
     }
  }
}
