Up voting prevents down voting.

[wmantly]

If you up vote something, then remove the vote by down voting you can down down vote again. This is also broken is the other direction. If you down vote then up vote(canceling you votes out), you cant up vote again.

there is a unique_together=('user_id', 'content_type', 'object_id', 'action') in the Model Vote and the issue you mentioned should not happen, can you check if this unique_together exists in your db?
