Every time I make a model with a File or Image Field I create a
corresponding boolean field called clear_fileFieldName. And then I
override the save action. Checking to see if that clear_fileFieldName
is set to true. If it is I, clear the FileField
Like this
class Property(models.Model):
thumbnail = models.ImageField(upload_to='images/thumbnails',
blank=True)
clear_thumbnail = models.BooleanField()
def save(self):
if self.clear_thumbnail:
self.clear_thumbnail = False
self.thumbnail = ''
super(Property, self).save()
It's kind of a hack, but it works for now.
