Re: How to create model for this json data
Hi,
First, try to understand the error messages. It says there are fields that are
required, but you are leaving them blank. Then, there are some fields those
cannot have "null", but soemhow you are adding null values to them.
I would suggest using below Django CLI commands to add the data to your table
python manage.py loaddata .
Below is the link that will guide you with further informationDjango dumpdata
and loaddata (Example)

RE: How to create model for this json data
You can use ForeignKey.
Or ArrayField if you're using PostgreSQL as your backend.
