Django Admin Upload And Image To S3 And Then Resize The Image And Save A Thumb Problem

I am having error after error trying to upload and resize images to s3 with pil and botos3 and the django default_storage. I am trying to do this on save in the admin. here is the

Solution 1:

I had a similar problem, but in my case using sorl-thumbnail was not an option. I found that I can open an Image directly from S3BotoStorage by passing in a file descriptor instead of a path.

So instead of

thumb = Image.open(self.image.path)

use

thumb = Image.open(s3_storage.open(self.image.name))

Then you can process and save the new file locally as you were doing before.

Solution 2:

Why don't you try sorl-thumbnail. It has the exact same interface as the default ImageField django provides and it seems like it would be a lot nicer to work with than the roll-your-own support.
