Schema and defaults

[yychen]

Description

It's very likely that there would be some sort of schema and default values for the keys. For example, a developer sets up the django environment, but then a manual re-creation of all the keys are required. It would be easier if there's a way to define the schema and build it automatically with default values.

Possible Solutions

I'm thinking maybe read a schema toml or yaml file from a fixed location, and we can build a django-admin command to initialize the keys.

Additional context

I think this should be another feature request. For the "string" type keys, it would be good to constraint the values, something like a single choice. Then, we can define what are the valid values in the schema.
