I'm all kinds of stuck here -- I've tried using loaddata from the Django docs but I'm getting errors I don't understand and can't find anything about online, so I've decided to try the route of adding a class method to the Mineral model that reads the JSON file and saves new instances based on its contents, and then just running it from the Django admin shell. There's some discussion and examples about it here:

My model and class method are exactly like Alexey's in the first post, but upon calling the class method in the shell, I get KeyError: 'refractive index'. I know this has to do with the fact that the first mineral/dictionary in the JSON file doesn't have a 'refractive index'. I've added default='' to that field on my Mineral model but it doesn't solve the problem. Any ideas? What have other people done to get over this initial hurdle?
