Using Django database layer outside of Django?
I've got a nice database I've created in Django, and I'd like to interface with through some python scripts outside of my website stuff, so I'm curious if it's possible to use the Django database API outside of a Django site, and if so does anyone have any info on how it can be done? Google hasn't yielded many hits for this.
You just need to configure the Django settings before you do any calls, including importing your models. Something like this:
from django.conf import settings
settings.configure(
DATABASE_ENGINE = 'postgresql_psycopg2',
DATABASE_NAME = 'db_name',
DATABASE_USER = 'db_user',
DATABASE_PASSWORD = 'db_pass',
DATABASE_HOST = 'localhost',
DATABASE_PORT = '5432',
TIME_ZONE = 'America/New_York',
)
Again, be sure to run that code before running, e.g.:
from your_app.models import *
Then just use the DB API as usual.
For django 1.7, I used the following to get up and running.
settings.py:
from django.conf import settings
settings.configure(
DATABASES={
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'name',
'USER': 'usr',
'PASSWORD': 'secret',
'HOST': '127.0.0.1',
'PORT': '5432',
},
},
TIME_ZONE='America/Montreal',
)
In the file containing the startup routine
import os
import django
import v10consolidator.settings
from myapp.models import *
os.environ.setdefault(
"DJANGO_SETTINGS_MODULE",
"myapp.settings"
)
django.setup()
Update setup_environ is to be removed in django 1.6
If you're able to import your settings.py file, then take a look at handy setup_environ command.
from django.core.management import setup_environ
from mysite import settings
setup_environ(settings)
#here you can do everything you could in your project
I was looking for answers for django 3.0 and none of the above method exactly worked for me.
I read the official docs at https://docs.djangoproject.com/en/3.0/topics/settings/ and this scripts worked for me.
my script db_tasks.py is inside mysite like this.
mysite
mysite
db.sqlite3
db_tasks.py
manage.py
polls
db_tasks.py
import os
import django
os.environ['DJANGO_SETTINGS_MODULE'] = 'dashboard.settings'
django.setup()
from polls.models import Question
print(Question.objects.all())
out: <QuerySet [<Question: WTU?]>
