django-avatar: cant save thumbnail
- by Znack
I'm use django-avatar app and can't make it to save thumbnails. The original image save normally in my media dir.
Using the step execution showed that error occurred here
image.save(thumb, settings.AVATAR_THUMB_FORMAT, quality=quality)
I found this line in create_thumbnail:
def create_thumbnail(self, size, quality=None):
# invalidate the cache of the thumbnail with the given size first
invalidate_cache(self.user, size)
try:
orig = self.avatar.storage.open(self.avatar.name, 'rb')
image = Image.open(orig)
quality = quality or settings.AVATAR_THUMB_QUALITY
w, h = image.size
if w != size or h != size:
if w > h:
diff = int((w - h) / 2)
image = image.crop((diff, 0, w - diff, h))
else:
diff = int((h - w) / 2)
image = image.crop((0, diff, w, h - diff))
if image.mode != "RGB":
image = image.convert("RGB")
image = image.resize((size, size), settings.AVATAR_RESIZE_METHOD)
thumb = six.BytesIO()
image.save(thumb, settings.AVATAR_THUMB_FORMAT, quality=quality)
thumb_file = ContentFile(thumb.getvalue())
else:
thumb_file = File(orig)
thumb = self.avatar.storage.save(self.avatar_name(size), thumb_file)
except IOError:
return # What should we do here? Render a "sorry, didn't work" img?
maybe all I need is just some library?
Thanks
