In some older group post I found a nice django-based solution: Using a
customized ImageField instance:
class MyImageField(ImageField):
def __init__(self, *args, **kwargs):
super(MyImageField, self).__init__(*args, **kwargs)
def clean(self, *args, **kwargs):
data = super(MyImageField, self).clean(*args, **kwargs)
data.name = slugify_name(data.name)
return data
