How to clean a form which receives multiple files

I am not happy with this snippet from the django docs:


from django.views.generic.edit import FormView  from .forms import FileFieldForm    class FileFieldView(FormView):      form_class = FileFieldForm      template_name = 'upload.html'  # Replace with your template.      success_url = '...'  # Replace with your URL or reverse().        def post(self, request, *args, **kwargs):          form_class = self.get_form_class()          form = self.get_form(form_class)          files = request.FILES.getlist('file_field')          if form.is_valid():              for f in files:                  ...  # Do something with each file.              return self.form_valid(form)          else:              return self.form_invalid(form)  

Source: https://docs.djangoproject.com/en/1.11/topics/http/file-uploads/#uploading-multiple-files

My problem: The form instance can't validate the files.

AFAIK in the method form.clean() I don't have a list of files.

I can work around this, but it breaks the nice separation of concerns which
I usually get with the nice django form library :-) 

Imagine my app receives three files. Is there a way to validate these files inside form.clean()?
