How to Connect to a PostgreSQL Database on a Different Host in waymarkedtrails-backend Project?

[atasc]

Hi,
I have followed the instructions to install and configure the waymarkedtrails-backend project. I created the wmt_local_config/backend.py file with the following configurations:

from pathlib import Path

DB_HOST = '192.168.1.100'  # not working
DB_PORT = 5432
DB_NAME = 'waymarkedtrails'
DB_USER = 'postgres'
DB_PASSWORD = 'xxxxxxxxxx'

SYMBOL_DIR = Path('/home/xxx/Maps/WaymarkedTrails/waymarked-trails-site/maps/symbols')

However, I haven't found a way to connect to a PostgreSQL database that is hosted on a different machine.

Where should I configure the connection string like postgresql://user:password@host_ip/waymarkedtrails to successfully connect to a remote PostgreSQL database?

Thanks for your help!

Best regards,

Andrea
