I'm using an avatar imagefiled in the model and have defined an
imagefield in the registration form I'm using for the user to sign up.
avatar is not a required field (both in the form as well as in the
model)
I've got validation included in the Registration Form for the uploaded
image size:
def clean_avatar(self):
size = len(self.cleaned_data['avatar'].content)
if size > 500 * 1024:
raise forms.ValidationError('Size exceeded allowable
limit')
return self.cleaned_data['avatar']
All works well if the user does upload an image. If no image is
uploaded, I get a
"NoneType' object has no attribute 'content' " exception.
Which I understand why -- because no file has been uploaded and so
there is no content attribute present.
however, I'm not sure how I can first check if a file has been
uploaded by user or not..and then have the above clean method be
invoked only when a file has been uploaded...if not, skip validating
the input.
any ideas ?
