[Answered ]-Building query string with form fields

✅

Don’t reinvent the wheel by constructing your own query and use the power of Django ORM.

For example:

marca = request.POST.get('marca')
modelo = request.POST.get('modelo')
tamano_min = request.POST.get('tamano_min')

latest_products = products.objects.filter(brand=marca, model=modelo, size__gte=tamano_min)

get() helps to get the value of POST parameter or None if no parameter found in the dictionary.
__gte ending helps to add >= condition.

You may also want to check marca, modelo and tamano_min before using them:

latest_products = products.objects.all()
if marca is not None:
    latest_products = latest_products.filter(brand=marca)

And so on.
