I want to only .xlsm files to be uploadable to the form.I tried a lot of thing according to this question. But did not work. I don't know why? How can I solve it?

models.py

from django.core.validators import FileExtensionValidator
...
    pdf = models.FileField(upload_to=customer_directory_path, null=True, blank=True, validators=[FileExtensionValidator(allowed_extensions=['xlsm'])])

...

When I add this to my model :

def clean(self):
    pattern = re.compile('.*/.xlsm$')

    if not pattern.search(self.pdf):
        raise ValidationError(_('Only .xlsm files are accepted'))

I get an error:

expected string or bytes-like object

Did you try to run the validators in forms.py? – David Aug 10 '21 at 08:52
the field definition in model is enough for your goal. Why you are doing extra validation in `clean` method? – Elgin Cahangirov Aug 10 '21 at 08:54
Cause of the error is `self.pdf` I think. At the time `clean` method invoked `self.pdf` is blank or null – Elgin Cahangirov Aug 10 '21 at 08:55
@David I did nothing in forms. What should I do? – edche Aug 10 '21 at 08:59
@ElginCahangirov I tried both of them seperately – edche Aug 10 '21 at 09:00
@edche try to add breakpoint to you `clean` method and look at the value of `self.pdf` – Elgin Cahangirov Aug 10 '21 at 11:39
