User Defined Settings

[Ryan Quinn]

Is there a place for user defined settings? Stuff that isn't going to change that often, but still might need to be tweaked from time to time?

Here's the scenario. I'm creating objects, and I'm setting an expiration date X days in the future. I have a custom create function in my serializer setting the "expiration" field to the future date, and it's working well. Everything is getting set correctly.

validated_data['expiration'] = datetime.datetime.now( datetime.timezone.utc ) + datetime.timedelta( days=40 )

The problem is, the code needs to be changed if I want to raise or lower the time the objects are stored, and I would like to move this into a config file to make it easier to work with. It's a system wide setting, and the admin gets to pick how long the objects are stored.

I found the settings page in the docs, and it works fine with existing variables. It doesn't work when I add my own variables. This does not work.

settings.py:

  RET_FRAMEWORK = {

    ...

    'OBJEXP': 4,

  }

serializers.py:

  days = api_settings.OBJEXP
  validated_data['expiration'] = datetime.datetime.now(datetime.timezone.utc) + datetime.timedelta(days=days)

What am I missing?

Thanks in advance!

Why not to use a Mixin?

By doing that, you could override for example, the save method and call it at the end of you implementation.

I think it would be good because  of the explicity (Mixins are clearly showed on the classes top)
