I am trying to access my Django (v1.10) app DB from another python script and having some trouble doing so.
This is my file and folder structure:
store store __init.py__ settings.py urls.py wsgi.py store_app __init.py__ admin.py apps.py models.py ... db.sqlite3 manage.py other_script.py
In accordance with Django's documentations my other_script.py
looks like this:
import django from django.conf import settings settings.configure(DEBUG=True) django.setup() from store.store_app.models import MyModel
But it generates a runtime error:
RunTimeError: Model class store.store_app.models.MyModel doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
I should note that my INSTALLED_APPS
list contains store_app
as its last element.
If instead I try to pass a config like this:
import django from django.conf import settings from store.store_app.apps import StoreAppConfig settings.configure(StoreAppConfig, DEBUG=True) django.setup() from store.store_app.models import MyModel
I get:
AttributeError: type object 'StoreAppConfig has no attribute 'LOGGING_CONFIG'.
If I edit settings.py
and add LOGGING_CONFIG=None
I get another error about another missing attribute, and so on.
Any suggestions will be appreciated.
Now, since we want to use Django's ORM, we have to have Django running for which we need a manage.py file. Let's create a default manage.py by copying it from one of the past project or the code below. Make sure you define a correct relative import path for settings in Line 4. Let's create our settings.py file now.
It is used if you run your Django app as standalone. It will load your settings and populate Django's application registry. You can read the detail on the Django documentation.
Although it is not recommended to run python scripts from Django shell, this is a great way to run background tasks. This is because when you run python scripts from Django shell, it gives you access to all models, views and functions defined in your Django project.
Try this
import sys, os, django sys.path.append("/path/to/store") #here store is root folder(means parent). os.environ.setdefault("DJANGO_SETTINGS_MODULE", "store.settings") django.setup() from store_app.models import MyModel
This script you can use anywhere in your system.
This sounds like a great use case for Django Management commands. which has the added bonus you can run it scheduled from cron, direct from the commandline, or call from inside django. This gives the script full access to the same settings and environment variables as your main project.
If you move this into an appropriate directory - using store here as an example, not a suggestion, it should work.
store management __init__.py commands __init__.py otherscript.py
