Hi All,
I have a Model with an image field and I want to be able to change the
image using a ModelForm. When changing the image, the old image should be
deleted and replaced by the new image.
I have tried to do this in the clean method of the ModelForm like this:
def clean(self):
cleaned_data = super(ModelForm, self).clean()
old_profile_image = self.instance.image
if old_profile_image:
old_profile_image.delete(save=False)
return cleaned_data
This works fine unless the file indicated by the user is not correct (for
example if its not an image), which result in the image being deleted
without any new images being saved. I would like to know where is the best
place to delete the old image? By this I mean where can I be sure that the
new image is correct before deleting the old one? I prefer to do this in my
ModelForm class if possible but doing it in the Model class would also be
acceptable.
