Loading pre-existing data into Django project

Question

I have a pre-existing db file 'sample.db' in sqlite3 format that I'm trying to import into my Django project. I've already added it to the settings.py file:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    },
    'sample': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'sample.db',
}

I was able to generate the model.py in my application folder using inspectdb. I have run makemigrations and migrate and everything seems to be fine.

I try to get some data in my views.py: obj = table_name.objects.get(id=1)

Then I start the server: python manage.py runserver, and try to load a page at http://127.0.0.1:8000/

It displays an error message saying: NameError at / Name table_name is not defined

What did I miss?

Thank you!

As you've added your sample database to your settings as sample you need to ensure your queries are using the correct database.

For example obj = table_name.objects.get(id=1).using('sample')

The alternative would be to configure your database to be the default setting.
