I am a bit confused about the settings for django.
I have something like this setup in my settings.py file locally:
"""
Django settings for ebportfolio project.
Generated by 'django-admin startproject' using Django 3.1.6.
For more information on this file, see
https://docs.djangoproject.com/en/3.1/topics/settings/

django_heroku.settings(locals())
With the DEBUG=on in my.env file DEBUG=True, the images show both online and locally. When I switch DEBUG=off in.env the images don't show up running locally. Can someone explain to me why? Is DEBUG influencing where the files are showing from?
Edit whilst writing the post - I changed my heroku URL in allowed hosts to include https:// and now the images show. What documentation shall I look into to understand this?
Because off
is treated as a string and a non empty string is still truthy
You need to remove DEBUG
from the env file altogether for it to be set to false (or a falsy value such as DEBUG=0
)
