BTW, Had a typo in the dpaste code. Line 19 should say:
img_obj.save_image_file(uploaded['filename'], uploaded['content'])
You don't have to duplicate code, well not duplicate too much. That's
why the image validation method in the form is separate from the
*_clean methods. In my app, I had to allow up to four simultaneous
uploads. You have to set a limit to the number of uploads because if
you don't you will be bound to hit the limits of your server anyway.
Create a form with the number of image fields numbered in sequence. For example:
img_fld1
img_fld2
img_fld3
...
Then when you do your processing in your view, simply wrap the code
that saves the images in a loop:
for n in range(0, MAX_NUM_UPLOADS):
img_manip = ImageAttachment.AddManipulator()
img_obj = img_manip.save()
uploaded = clean_data['img_fld%d' % n]
obj.save_image_file(uploaded['filename'], uploaded['content'])
For validation, I haven't tried it yet, but I think you should be able
to implement it using __getattr__ to handle it. That way you don't
have to duplicate validation code.
