I wonder if every View in Mvc has to be typed?
I want to get values from a form but these values are not from the same entity. I'm using a helper:
@Html.TexBoxFor(model => model.Nome)
I would like to know how to get the value of this helper without using model => model.Nome and nome is a property of an entity. When not type my view does not catch the value of the textbox.
In this case, you need to create a ViewModel . A ViewModel is identical to a Model , but does not store information in a database.
Place all the properties of the various Models into it that will be saved. When sending to the Controller , you will have to create the Models manually and enter the information in the ViewModel into them.
[HttpPost]
public ActionResult MinhaAction(MeuViewModel viewModel)
{
if (ModelState.IsValid)
{
var model1 = new MeuModel1();
model1.Prop1 = viewModel.Prop1;
model1.Prop2 = viewModel.Prop2;
...
context.MeuModel1.Add(model1);
context.SaveChanges();
var model2 = new MeuModel2();
model2.Prop1 = viewModel.Prop3;
model2.Prop2 = viewModel.Prop4;
...
context.MeuModel2.Add(model2);
context.SaveChanges();
return RedirectToAction("OutraAction");
}
// Caso o ViewModel não seja válido, cai aqui.
return View(viewModel);
}
