@DoctorJohn Nice work, can you also add some test for this, that will be better.

FYI you can change .travis.yml to add test for Django 2.0

Furtunately there is already a test in place (good job guys). I tried to add django 2.0 to travis.yml. Django 2.0 requires python 3. Dunno whether I added django 2.0 correctly.

@DoctorJohn you can add Django 2.0 to env and exclude 2.7 in exclude block below

[DoctorJohn]

@shellfly like so?

[shellfly]

@DoctorJohn Exactly, LGTM, I will merge this, thanks for you work.

@DoctorJohn FYI I have made a new release for your pull request, you can install django-vote==2.1.7 if you need.
