replace the exiting upload_location function with this code snippet. I have already ported my db to Postgres, hence I ain't making a pull request.

"""
instance.__class__ gets the model Post. We must use this method because the model is defined below.
Then create a queryset ordered by the "id"s of each object,
Then we get the last object in the queryset with `.last()`
Which will give us the most recently created Model instance
We add 1 to it, so we get what should be the same id as the the post we are creating.
