Django forms: "This field is required" when the file is POSTed in the file field

Question

For some reason, I cannot get the file in my file field in ModelForm. The file is sent and the file name is in the corresponding POST request, but it form.is_valid()fails because it indicates{'the_file': [u'This field is required.']}

I wrote ModelForm for a model with a file field and a foreign key to another model, this way:

class AccountFile(models.Model):
the_file = models.FileField(upload_to='{}/%Y/%m/%d/'.format(
    settings.MEDIA_ROOT,
))
account = models.ForeignKey(
    Account,
    blank=True,
    null=True,
    related_name='account_files'

Then I created a form for uploading a file like this:

class UploadFileForm(forms.ModelForm):
class Meta:
    model = models.AccountFile
    fields = ['the_file' ]


def clean_file(self):
    file = self.cleaned_data.get("the_file", False)
    filetype = magic.from_buffer(file.read())
    if not "pdf" in filetype:
        raise forms.ValidationError("File is not pdf.")
    return file

We introduce some basic check (which will be expanded!) When I can get at least one thing to work with.

The form is processed as follows:

if request.method == 'POST':
    form = forms.UploadFileForm(request.POST, request.FILES)
    if form.is_valid():
        handle_uploaded_file(request.FILES['file'])
        return redirect(
            'account_url',
            acc_manager_pk=acc_manager.pk,
            account_pk=account.pk,
            )
else:
    form = forms.UploadFileForm()

This is on Django 1.7
