up.

Thanks for this!

I think it's missing a few things:
1/ the south app should be removed from https://github.com/magopian/django-data-exports/blob/master/data_exports/settings.py#L11
2/ there's still a reference to a south command in the https://github.com/magopian/django-data-exports/blob/a73db486779d93046ad89c5bf582ff8ae869120f/README.rst on line 50

This is looking good, thanks for your work.

South 1.0+ still works for django 1.7- …
settings and doc should differ depending on the django version…

[magopian]

Are, you're right ;)

Could you please slightly amend the doc to talk about the two cases (django 1.7- and south, or django 1.8+)?

Thanks!
