How to fix: "RuntimeWarning: Model  was already registered."
It is saying that you have  already registered the model before
Hence by deleting the second model or writing the code in the specified model is the solution for this .
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?
