In cases where something other than the
DATABASE_URL
needs to be set, it was previously hard to know how to customisedj-database-url
's config, since the upstream docs don't mention theenv
option:jazzband/dj-database-url#248
Now our default config passes an explicit value for
env
(which matches the default value for that argument), to improve discoverability.In addition, the Heroku Postgres docs link has been updated to deep link to the env vars section, which explains when/why DB env vars will be given alternate colour-prefixed names.
Closes #221.
