Make Downvote -1

[Brotakuu]

Is it possible to make downvote decrement 1, instead of just removing the upvote?

So negative numbers is possible. And down voting without upvoting is possible.

For the present, the Vote model can't implement the downvote function. To implement this you have to add another field to record the upvote or downvote action。

It's not as easy as just adding another field, because both your upvote and downvote field will end up going through the Vote class, so when a user upvotes and you try to do:

obj.upvotes.up(user)
obj.downvotes.down(user)

the second call destroys the first vote.

I made a trivial subclass of Vote called Downvote, and made my downvotes field thusly:

downvotes = VotingManager(through=Downvote)

which does the right thing, but now I'm running into other issues; specifically that Django can't filter on GenericForeignKeys, so code like:

self.through.objects.filter(user=user, content_object=self.instance).delete()

doesn't work -- it generates the error:

FieldError: Field 'content_object' does not generate an automatic reverse relation and therefore cannot be used for reverse querying. If it is a GenericForeignKey, consider adding a GenericRelation.

This is with Django 1.8.3.
