Django loaddata and 'invalid model identifier' error
You should be able to simply change the app name in the JSON and be fine.
I have this dump.json with data from a Django-project that I'm trying to load (manage.py loaddata) into another project where I've set up the same model/fields etc. The problem is the "app" is not named the same in the two projects. So I get this 'invalid model identifier' -error. 
What to do?
