How to fix: "RuntimeWarning: Model  was already registered."
Check in your models if you don't got a duplicate class model, sometimes when we make a rebase or merge in our existing branches, our code can be duplicated, i had the same problem, isn't a big deal.
Since upgrading Django, I've been getting this error in iPython when I do imports:

RuntimeWarning: Model 'docket.search' was already registered. Reloading models is not advised as it can lead to inconsistencies, most notably with related models.

I'm guessing this is some automatic feature of iPython, but is there an easy solution? Is this something I even need to solve?
