How to use multiple models in a view

Question

I’m doing a criminal record and I have the following models:

• Pessoa
• Fisica
• Juridica

And in the code of mine view I have only the declaration of a model:

@model CodeFirst.Models.Fisica

The problem is that when I go to make a record inside my view, it will be necessary for me to have access to the 3 models listed above. How do I access them?

Answer 1

That is one of the reasons why a view model is used, a view model is a model which should be used exclusively to encapsulate data that will be sent to the view. So instead of you sending one model directly to the view, you encapsulate him inside a view model along with other data you want to view have access.

In your case, what could be done is the following, you would create a class inside the folder /Models of your project following the [NomeDaViewOndeSeráUtilizada]ViewModel and within this class you would create a property for each of these models. Take an example:

public class IndexViewModel
{
    public Pessoa Pessoa { get; set; }
    public Fisica Fisica { get; set; }
    public Juridica Juridica { get; set; }
}

And the action who would return this view model could turn out like this:

public ActionResult Index()
{
    var viewModel = new IndexViewModel();

    // Preencha as propriedades do objeto viewModel como desejar
    // e o retorne para a view

    return View(viewModel);
}
