Hi,
I am stuck on the interface between a PIL Image and a
FilesystemStorage 'content' object.
I can: img = Image.open(content)
But how do I pass 'img' back to Django for saving?
My short class is pasted at end. The problem reported stems from the line:
name=super(CustomImageStorage,self).save(name,img)
It barfs in PIL saying:
Exception Type: AttributeError
Exception Value:
chunks
Exception Location: /usr/lib/python2.5/site-packages/PIL/Image.py in
__getattr__, line 493
I dir() the content and img objects and sure enough, img has no 'chunks'
attribute.
Anyway, I can always use img.save(path) but wanted to keep the image in memory
and not touch ground with it.
Any ideas?

Code:
class CustomImageStorage( FileSystemStorage ):
def __init__(self, location, base_url,
makethumbs=False,dropshadow=None):
super(CustomImageStorage,self).__init__(location=location,base_url=base_url)
self._makethumbs = makethumbs
self._dropshadow = dropshadow
def get_available_name( self, name ):
self.delete(name)
return name
def save(self, name, content ):
content.seek(0)
img = Image.open(content)
if self._dropshadow:
img = dropShadow(img, background =
self._dropshadow['background'],
shadow = self._dropshadow['shadow'],
offset = self._dropshadow['offset'],
iterations =
self._dropshadow['iterations'],
border = self._dropshadow['border']
)
if self._makethumbs:
try:
thumb = img.copy()
fpaf = self.thumbPath(name)
thumb.thumbnail((64,64),Image.ANTIALIAS)
thumb.save( fpaf )
except:
pass # some damn error.
img.seek(0) # Random attempt at a fix
name = super( CustomImageStorage,self).save(name,img) # was
content
return name
def delete( self, name):
super(CustomImageStorage,self).delete(name)
if self._makethumbs:
# Now to remove the thumbnail too.
try:
fpaf = self.thumbPath(name)
os.unlink( fpaf )
except:
pass # Can't delete it... whatever.
def thumbPath( self, name ):
return os.path.join(self.location,'djanthumbs', name)
