finding local postgresql “database_url”
Looking at file main.py
line 22 contains "os.environ['DATABASE_URL']"
you should set the environment variable DATABASE_URL
on your computer to a value that is the location of your database. Eg: set DATABASE_URL=C:\Users\Philip\mydatabasefile
See The docs The general form for a connection URI is:
postgresql://[user[:password]@][netloc][:port][,...][/dbname][?param1=value1&...]
You probably need to set you environment variable DATABASE_URL to something like
set DATABASE_URL=user:password@localhost/dbname
You can display your connection info if logged into postgres shell with command:
\conninfo
this will display the database you are connected to as well as the user logged on
