A small script that takes a manage.py dumpdata generated json file, and removes fields of the specified models. I needed this because i kept my initial data on a json file and after I removed a field on one of my models, the script wouldn't work anymore.

def fix_dump(in_file, out_file, model, *remove_fields):
content = json.load(open(in_file))
for item in content:
if item['model'] == model:
for field in remove_fields:
if field in item['fields']:
del item['fields'][field]
json.dump(content, open(out_file, 'w'))
