Package: python3-django
Version: 2:2.2.23-1
Severity: important

Dear Maintainer,

while working on a local Django application based on the Django version
avaialable in unstable/testing we want to use on may day
job I noticed while preparing this all into a Debian package the package
is failing while installion on a fresh and clean system in case I use
the switch '--no-install-recommends' for package installion.

I'm doing this because our Django application is intended to run on a
server system which are always configured to install packages without
recommended packages.

Our local Django application is called 'patchy2' and this is depending
on a new Debian package python3-django-crispy-forms-foundation which is
awaiting further processing in the NEW queue currently.

I run the installation on a fresh system installed by debootstrap
without addional added packages except the packages that are installed by
the installer automatically for a non X-system.

So looking around for the missing file indeed I see this isn't there.
Looking at the python3-django package I can see that the package
libjs-jquery isn't a hard dependency and only recommended.

I've no deeper knowledge on Django yet :-) but to me it looks like the
libjs-jquery package should be in the Depends and not only in the recommends
field.

I haven't found some information within the doc folder for the package
why libjs-jquery isn't a hard dependency and maybe I miss something, if
so it would be nice if at least some information about the rationale can
be placed with the documentation for python3-django.

Long story short, if I install libjs-jquery prior or also appended to my
local list of packages all went fine.

Regards
Carsten
