How to share django database model between projects in Docker

I have following service structure:

service1/
    Dockerfile
    manage.py
    settings.py
    ..
service2/
    Dockerfile
    manage.py
    settings.py
    ..
databasemodel/
    Dockerfile
    manage.py
    settings.py
    database/
        models.py

Each service and database models has it's own git repository.

How do I share common django database model between them (both services connect to same database). I have implemented manual copying of "database" folder over to service1 and service2, but it feels wrong. I feel like implementing some anti-pattern.

I need setup for:

1) development on local machine (something that would bring up database and both services)

2) deployment so that dev-ops team can deploy each git repo to server

I am very inexperienced with Django and Python and Docker and Git, please do not assume that I know trivial truths. :)

EDIT: I am free to change this structure how I please, however solution should still have git-repo for each service and database models
