Hello, I am trying to prevent models in my api app from migrating into the
default database but I'm confused about the router. It seems every time I run
migrate even with the router it continues to migrate.
#apps.py
from django.apps import AppConfig
class ApiConfig(AppConfig):
name = 'api'
label = 'api'
#settings.py
DATABASE_ROUTERS = ['myproject.dev_db_router.APIRouter',]
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'default.sqlite3'),
},
'mydb': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'mydb.sqlite3'),
},
}
#dev_db_router.py
class APIRouter:
"""
A router to control all database operations on models in the
api application.
"""
route_app_labels = {'api',}
def db_for_read(self, model, **hints):
"""
Attempts to read api models go to mydb.
"""
if model._meta.app_label in self.route_app_labels:
return 'mydb'
return False
def db_for_write(self, model, **hints):
"""
Attempts to write api models goes to mydb.
"""
if model._meta.app_label in self.route_app_labels:
return 'mydb'
return False
def allow_migrate(self, db, app_label, model_name=None, **hints):
"""
Make sure the api app only appears in the
'mydb' database.
"""
if app_label in self.route_app_labels:
return db == 'mydb'
return False
I've tried:
python manage.py migrate --database=default
python manage.py migrate
etc and every time it says:
Applying api.0001_initial...* OK*
Even though I told it False if it does not meet the case of db == 'mydb'. I can
specify 'mydb' and it says it works:
python manage.py migrate --database=mosaic
but my concern is it always migrates into default even when I'm trying to tell
it not to. In the future there will be models I do want to migrate into
default, but not these in the api app. Based on the documentation I'm doing
everything correctly.
What am I not understanding?
Thank you.
Best,
JJ
