Django ImageField overwrites existing path when empty

So, that's the problem: I currently have a model:

class UserData(models.Model):
    avatar = models.ImageField(verbose_name='Avatar',upload_to='images/profile_pics',blank=True,null=True)
    doc_type = models.CharField(verbose_name='Document type',max_length=1,default='0')

And a form:

class UserCreationForm(forms.ModelForm):
    avatar = forms.ImageField(label='Avatar',required=False, error_messages = {'invalid':"Images only"}, widget=forms.FileInput)
    class Meta:
        model = UserData

So, the problem occurs when the user tries to edit his data. When no image is provided, the current image path in the db overwrites with the empty string. Is there any way to solve that problem?

from django.db import connection

@login_required

def card_photo_remove(request, pk): card = get_object_or_404(Cards, cardid=pk)

if card.sponsorimage:
    default_storage.delete(card.sponsorimage.path)

with connection.cursor() as cursor:
    cursor.execute("UPDATE Cards SET SponsorImage=NULL WHERE cardid=%s", [pk])

return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

Here u can see exaple how to write manyal SQL code. It worked to me perfectly!

Remove both blank and null equal to True

blank=True

Allows the field to be empty

null=True

Allows the empty data to be saved in database

so you can choose which one will work for you the best.

You can solve the problem by making image field required.

avatar = forms.ImageField(label='Avatar', required=True, error_messages={'invalid':"Images only"}, widget=forms.FileInput)

avatar = models.ImageField(verbose_name='Avatar',upload_to='images/profile_pics',null=True)

removing blank=True should solve it
