I was hunting around the net for a way to easily allow users to blank out imagefield/filefields they have set in the admin.
I found this
http://www.djangosnippets.org/snippets/894/
What was really interesting to me here was the code posted in the comment by rfugger
remove_the_file = forms.BooleanField(required=False)
def save(self, *args, **kwargs):
object = super(self.__class__, self).save(*args, **kwargs)
if self.cleaned_data.get('remove_the_file'):
object.the_file = ''
return object
When i try to use this in my own form I basically added this to my admin.py which already had a BlahAdmin
class BlahModelForm(forms.ModelForm):
class Meta:
model = Blah
remove_img01 = forms.BooleanField(required=False)
def save(self, *args, **kwargs):
object = super(self.__class__, self).save(*args, **kwargs)
if self.cleaned_data.get('remove_img01'):
object.img01 = ''
return object
when i run it I get this error
maximum recursion depth exceeded while calling a Python object
at this line
object = super(self.__class__, self).save(*args, **kwargs)
When i think about it for a bit, it seems obvious that it is just infinitely calling itself causing the error. My problem is i can't figure out what is the correct way i should be doing this. Any suggestions?
thanks
