I encountered this while trying to use an uploaded image (using a form
with ImageField) with PIL. The relevant code is as below:
{{{
import PIL
def Avatar_file_handler(personInstance, avatarImage):
"""Writes the avatarImage to personInstance after necessary processing
avatarImage is an UploadedFile object"""
im = PIL.Image.open(avatarImage)
# *** Error on this line!
}}}
The pdb trace is as follows:
{{{
-> im = Image.open(avatarImage)
(Pdb) Image.open(avatarImage)
*** AttributeError: 'InMemoryUploadedFile' object has no attribute
'readline'
(Pdb) s
