One lightweight trick is to make a redirect in your urls.py
file, e.g. add a view like so:
from django.views.generic.base import RedirectView
favicon_view = RedirectView.as_view(url='/static/favicon.ico', permanent=True)
urlpatterns = [
...
re_path(r'^favicon\.ico$', favicon_view),
...
]
This works well as an easy trick for getting favicons working when you don't really have other static content to host.
