Django version 0.91. I was trying to generate a thumbnail for an image
upload. The image is a FileField. I want to generate thumbnail in
_post_save() of the model object. The code is something like the
following:
class Item(meta.Model):
...
file = meta.FileField(upload_to="files",blank=True)
...
def _post_save(self):
path = self.get_file_filename()
im = Image.open(path)
im.thumbnail((128,128))
(p1,p2) = path.split('.')
im.save(p1+"_tn."+p2)
What I found is everytime I do "add item" in admin interface,
self.get_file_filename() returns the path of MEDIA_ROOT, not the full
path of the image file uploaded. How to solve this problem? Thanks in
advance.
