For some reason, heroku tries to require dm-sqlite-adapter, even though it should use Postgres here. Note, that this happens when I open any URL - not during the git push itself
Well, too many Rails apps on Heroku, I took the shared db presence for granted. heroku config
showed neither DATABASE_URL
or SHARED_DATABASE_URL
set.
Issuing heroku addons:add shared-database:5mb
solved the problem.
Strange, that the db wasn't automatically added, despite having 'pg' gem in Gemfile.
Quote from http://devcenter.heroku.com/articles/cedar:
A Heroku shared PostgreSQL database (
shared-database:5mb
) will be automatically added to your app in any of the following cases:
- The app is a Rails application
- The
pg
gem is specified in theGemfile
