Docs Question: Currency Switcher - Missing info about code in controller?

Hello :waving_hand:
I am looking at the documentation for Implementing a Currency Switcher

Question

The partial has a form POST submission to a controller
Am I missing something or a reference to this in a previous article perhaps?

 @using (Html.BeginUmbracoForm("ChangeCountry", "Culture", FormMethod.Post, new { @name = "changeCountryForm" }))

But currently from this page I have no idea what happens inside the controller method and what it should do in order to switch the currency of the order.

Cheers,
Warren :slight_smile:

CultureSurfaceController.cs

public class CultureSurfaceController : SurfaceController
{
    private readonly IUmbracoCommerceApi _commerceApi;

    public CultureSurfaceController(
        IUmbracoContextAccessor umbracoContextAccessor, 
        IUmbracoDatabaseFactory databaseFactory, 
        ServiceContext services, 
        AppCaches appCaches, 
        IProfilingLogger profilingLogger, 
        IPublishedUrlProvider publishedUrlProvider,
        IUmbracoCommerceApi commerceApi) 
        : base(umbracoContextAccessor, databaseFactory, services, appCaches, profilingLogger, publishedUrlProvider)
    {
        _commerceApi = commerceApi;
    }
    
    [HttpPost]
    public async Task<IActionResult> ChangeCountry(ChangeCountryDto changeCountryDto)
    {
        var store = CurrentPage.GetStore();
        var country = await _commerceApi.GetCountryAsync(store.Id, changeCountryDto.CountryIsoCode);
        var currency = await _commerceApi.GetCurrencyAsync(country.DefaultCurrencyId.Value);
    
        await _commerceApi.SetDefaultPaymentCountryAsync(store.Id, country);
        await _commerceApi.SetDefaultShippingCountryAsync(store.Id, country);
        await _commerceApi.SetDefaultCurrencyAsync(store.Id, currency);
    
        var currentOrder = await _commerceApi.GetCurrentOrderAsync(store.Id);
        if (currentOrder != null)
        {
            await _commerceApi.Uow.ExecuteAsync(async uow =>
            {
                var writableOrder = await currentOrder.AsWritableAsync(uow)
                    .ClearPaymentCountryRegionAsync()
                    .ClearShippingCountryRegionAsync()
                    .SetCurrencyAsync(currency.Id);
    
                await _commerceApi.SaveOrderAsync(writableOrder);
    
                uow.Complete();
            });
        }
    
        return RedirectToCurrentUmbracoPage();
    }
}

ChangeCountryDto.cs

public class ChangeCountryDto
{
    public string CountryIsoCode { get; set; }
}
