📝 Multiple Models in a View: How to Handle Common Issues and Find Easy Solutions

Are you struggling with including multiple models in a single view? Do you find yourself in a situation where you need to display different models in the same page, such as a combination of a LoginViewModel and a RegisterViewModel? Don't worry, we've got you covered!

The Dilemma

So, you have two separate models - LoginViewModel and RegisterViewModel - and you want to display them on the same page. The first thought that might come to your mind is creating a BigViewModel that holds both LoginViewModel and RegisterViewModel. This would be a valid approach, but before you go down that path, let's explore an alternative solution.

The Alternative Approach

Instead of creating a BigViewModel, you can directly use the individual view models in the view itself. This approach eliminates the need for an additional layer of abstraction and simplifies your code. Here's how you can implement it:

@model ViewModel.RegisterViewModel
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Name)
    @Html.TextBoxFor(model => model.Email)
    @Html.PasswordFor(model => model.Password)
}

@model ViewModel.LoginViewModel
@using (Html.BeginForm("Login", "Auth", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Email)
    @Html.PasswordFor(model => model.Password)
}

Addressing Validation Attributes

You mentioned that you need the validation attributes to be applied to the view. The good news is that this alternative approach also retains the ability to apply validation attributes. Simply add the required validation attributes in your view models as you would normally do. The TextBoxFor and PasswordFor helper methods will automatically render the appropriate HTML with the validation attributes intact.

Why Choose the Alternative?

The main advantage of the alternative approach is simplicity. By directly using the individual view models, you avoid unnecessary complexity and keep your code clean. There's no need to create a separate view model (e.g., BigViewModel) just to hold other view models.
