Hi all,
We are trying to rewrite our webplattform because it has been developed
since 2009 and is more or less a patchwork of fixes.
In doing so, we want to be able to use the latest versions of all plugins
and frameworks, so we are looking at:
Django 1.6 (or 1.7 if it is released before September this year)
Python 3.4
The problem we have been seeing is that some required plugins are not
python 3 compatible, however, we have been able to patch them so far.
Now however I am facing a bigger problem. We are running our website on the
AWS plattform, so for storage we have S3. Previously we have been using
django-storages and boto so save files to S3.
I have changed to django-storages-py3 and the py3kport branch of boto. I
can download files from s3 and I can load files into BytesIO objects.
However I am not able to save a thumbnail image version of an image.
When I use pillow to save the image like this:
file = storage.open(output_fname, "wb")
image.save(file, "png")
file.close()
I get an exception in the image.save(file, "png") part.
File
"/home/anku/.virtualenvs/env/lib/python3.3/site-packages/PIL/Image.py",
line 1564, in save
save_handler(self, fp, filename)
File
"/home/anku/.virtualenvs/env/lib/python3.3/site-packages/PIL/PngImagePlugin.py",
line 546, in _save
fp.write(_MAGIC)
File
"/home/anku/.virtualenvs/env/lib/python3.3/site-packages/storages/backends/s3boto.py",
line 434, in write
return super(S3BotoStorageFile, self).write(*args, **kwargs)
TypeError: string argument expected, got 'bytes'
I understand WHY I get the error, but I can't figure out how to resolve it.
Anyone have any ideas?
Regards,
Andréas
