Define the database parameters as usual in the DATABASES
setting then add:
REDMINE_DATABASE = "the-redmine-db-key-in-DATABASES"
and define (or add) the database router:
DATABASE_ROUTERS = ["redmine_models.routers.DatabaseRouter"]
By default, it is supposed that an external redmine service is being accessed, and thus the models are unmanaged. If that's not desired, e.g. for testing you want the test tables to be created automatically, use the following setting:
REDMINE_MODELS_MANAGED = True
Then use the models:
from redmine_models.models import Project print Project.objects.all() # etc...
