Where is your data right now?
If you can put it into a separate database - or even a spreadsheet - it
can be automatically reloaded at any time.
There are two ways to do this. One is a data migration ...
https://docs.djangoproject.com/en/1.11/ref/migration-operations/#runpython
... and the other is a custom manage.py command ...
https://docs.djangoproject.com/en/1.11/howto/custom-management-commands/#module-django.core.management
In either case you write a function which uses Django's everyday tools
to insert data. If your data is in a flat file you can read it line by
line and extract the data you want, format it the way you want, run it
through any checks or tests you want then if it doesn't already exist
insert it.
I first used data migrations to insert reference data and worked out a
way to live with it. In effect, I had to insert 'return None' at a
strategic spot to prevent it running a second time.
Then I had a very complex data import with lots of m2m data represented
in a flat Excel spreadsheet and that was too ugly for a data migration
so I put in some study time and eventually built a manage.py command.
However, a possible third way might be found here ...
https://djangopackages.org/grids/g/countries/
I haven't used any so I can't tell you much.
Good luck
Mike
