Does django-constance admin supports database backend?

Question

I'm trying to setup the admin to show settings meant to be stored in database backend (Postgres 9.5.0). I manually created values in shell_plus as follows:

In [1]: from constance.backends.database.models import Constance

In [2]: first_record = Constance.objects.get(id=1)

In [3]: first_record Out[3]:

pg-admin properly shows the entry although django admin doesn't show it at all. I ran migrate command for both databases (I have default and product databases) but the record still is not showing up. Certainly I can make it work with forcing to register with admin as follows: admin.site.register(Constance) but my question is if it's necessary?

Answer 1

Yes, they do.

You need to manage dependencies, but you can just use next command to install:

pip install "django-constance[database]"

Also you need to add some additionl settings to your settings.py :

CONSTANCE_BACKEND = 'constance.backends.database.DatabaseBackend'

INSTALLED_APPS = (
    # other apps
    'constance.backends.database',
)

#optional - in case you want specify table prefix

CONSTANCE_DATABASE_PREFIX = 'constance:myproject:'

Then you need to apply migrations by running command python manage.py migrate database

For displaying settings inputs in admin you should specify them in your settings.py. There are various types of fields and you even can add your own types of fields using CONSTANCE_ADDITIONAL_FIELDS parameter.

CONSTANCE_CONFIG = {
    'THE_ANSWER': (42, 'Answer to the Ultimate Question of Life, '
                       'The Universe, and Everything'),
}
