There is a crud operations in default Single Page Application template of ASP.NET MVC 4 as below.
upshot.js is interacted with response from DbDataController's actions and if operation fails then upshot.js takes validation errors and it is able to show on client side.
What i need to do is putting my own business rules in operations. But it is not clear that where to put validation errors in DbDataController.
For example : InsertEntity(entity); Operation can put validation errors if it fails and validation errors sent to client automaticly. But i want to put my business validation errors if it is occur. So where can i put it there ?
public partial class TasksSPAController : DbDataController<MvcApplication8.Models.TasksSPAContext>
{
public IQueryable<MvcApplication8.Models.TodoItem> GetTodoItems() {
return DbContext.TodoItems.OrderBy(t => t.TodoItemId);
}
public void InsertTodoItem(MvcApplication8.Models.TodoItem entity) {
//before this action i want to check business validation rules.
// if it is not validated so i want to put errors to response
// that is usable by upshot.js
InsertEntity(entity);
}
public void UpdateTodoItem(MvcApplication8.Models.TodoItem entity) {
UpdateEntity(entity);
}
public void DeleteTodoItem(MvcApplication8.Models.TodoItem entity) {
DeleteEntity(entity);
}
}
