[Question] Postgresql setup

[andreierdoss]

I added the Heroku Postgres add on, which creates the DATABASE_URL

Once I restarted the scrapydweb server I got this error:

What else do I need to do to get this working?

What’s the value of DATABASE_URL?
How did you install scrapydweb, via pip or git?
