If I have a PostgresDB that contains both Django models and other SQL tables, is it possible to register these other SQL tables in the Django admin panel?
More details about the setup: I have a docker-compose setup where Django is running in one container, a Postgres DB in another, and a slack-app in a third container. Django is connected to the DB and the models are registered in the admin panel. This works as intended. The slack-app is also connected to the same DB and has some tables there that are not Django-models. I would like to also access these through the Django admin panel in order to have everything in one place. Is this possible?
You can define unmanaged models in Django. These models will not construct migrations, but will only query the database to select, insert, etc.
Django offers a tool inspectdb [Django-doc] to inspect the database and write the corresponding unamanged models. You thus can use this with:
python3 manage.py inspectdb table1 table2 tablenIt will then write the corresponding models for these tables to the standard output channel, and you thus can copy these in the models.py. In the Meta of these models it will add a managed = False to denote that Django will not migrate these models.
Once you registered these models, you can register a ModelAdmin with:
from django.contrib import admin
from app_name.models import Model1, Model2, Modeln
admin.site.register(Model1)
admin.site.register(Model2)
admin.site.register(Modeln)
