django-variable-settings

Build Status

A simple django application to manage dynamic settings saved in database using namespaced keys and json string values.

Demo

To try it now, download this repo and use docker-compose to run it

git clone [email protected]:jperelli/django-variable-settings.git
cd django-variable-settings
docker-compose up

Then go to http://localhost:8080/admin and login with user admin and password admin, you should see the Settings. If you add a settings, it should be a json object. So a string should be saved with double quotes around it.

It can be tested from django shell also easily. Go to another console while docker-compose up is running and type

docker-compose exec django ./manage.py shell
>>> import variable_settings
>>> variable_settings.set('evergreenstreet', 123)
>>> variable_settings.set('address.evergreenstreet', 123)
>>> variable_settings.set('address.evergreenavenue', 'first')
>>> variable_settings.get('evergreenstreet')
123
>>> variable_settings.get('address.evergreenavenue')
u'first'
>>> variable_settings.get('address.*')
{u'address.evergreenavenue': u'first', u'address.evergreenstreet': 123}
>>> variable_settings.all()
{u'address.evergreenavenue': u'first', u'evergreenstreet': 123, u'address.evergreenstreet': 123}

Installation

pip install django-variable-settings

In settings.py add

variable_settings

Then run migrations

manage.py migrate variable_settings

Then use it as in the Demo

Settings and custom command

If you want to add some default settings to the database then you can add something like this to settings.py

# default django_variable_settings
# use ./manage.py variable_settings_initialize
# If overwrite=False(default) they are not applied if already exist in database
VARIABLE_SETTINGS = [
    #[ key , value (, overwrite) ]
    ['alerting.connection', '127.0.0.1', False],
    ['alerting.warning', 123, False],
    ['wrong_permissions.enabled', True, True],
]

Use custom command ./manage.py variable_settings_initialize to save those in database. The command only overwrites the variable value if the last parameter is set to true
