Carlton—thanks very much for the feedback. Javier—likewise. In particular,
the imagined API you describe above is very appealing to me: start with
`from_env` and then if you learn more about this and want to, add in some
`EnvFileLoader`.
I want to make clear my motivation and agenda here: I have recently had
some conversations with newer devs about their experiences with deployment
of apps they're working on, and with a friend at Heroku about his informal
research into the problems people have with the same. One recurring
friction point (and this is not just on Heroku at all, to be clear) is that
there are a number of things that people *don't know they need to configure*
for a working deployment.
There are four settings that are recurring particular gotchas that people
miss: the secret key, debug, static files, and databases. Static files
seems big and out of scope, databases seems adequately handled by
dj-database-url for most cases, and if your case is more complex, you'll
learn it, but the other two (secret key and debug) seemed easy enough to
flag as "you probably need to configure these!" with this sort of change to
settings. This would be a first step towards shortening the distance from
`startproject` to a working deployment.
Newer devs in particular have, based on my conversations and this friend's
research, been unlikely to (a) know that there are different `startproject`
templates, and (b) feel equipped to choose one, if they do know.
My hope is to make the smallest possible change to just start us moving
towards more clearly flagging, especially for newer devs, "these are things
that will need additional configuration in order to move from 'works on my
machine' to 'deployed'."
Towards that end, I thought that adding a "you might want to get this from
the env" helper would be a clear indication to a new dev that this is a
matter to even consider. Adding other configuration-getting options like
different secret-store file backends seems like a good next step.
Thanks,
