I'm learning asp.net mvc and wonder when we need to use BindAttribute.
The first case (using Bind):
Model:
public class Book
{
public string Id { get; set; }
public string Name { get; set; }
public string Author { get; set; }
}
Controller:
public IActionResult Create([Bind(nameof(Book.Name), nameof(Book.Author))] Book model)
{
return Ok();
}
The book Id would be generated on server side. So, client side has nothing to do with it, every actions try to change/make the id is prevented.
The second case (not using Bind):
Model:
public class BookViewModel
{
public string Name { get; set; }
public string Author { get; set; }
}
Controller:
public IActionResult Create(BookViewModel model)
{
return Ok();
}
Because the second model doesn't contain Id property, we don't need to prevent from creating or changing.
I prefer the second. It's easy to manage model.
Is there a case we must use Bind attribute?
