Wrong requirement version for django-rq about ansible-role-netbox

[smutel]

So I found more details.
In old requirements.txt, we are finding django-rq but nothing about rq.

rq 1.3.x is working with django-rq 2.2.x
rq 1.4.x is working with django-rq 2.3.x

Putting this in my variable works for netbox 2.7.x:

netbox_pip_constraints:
  # Blacklist pynacl 1.3.0 due to https://github.com/pyca/pynacl/issues/479
  - 'pynacl!=1.3.0'                                                                                 
  # Blacklist rq 1.3.0 due to https://github.com/rq/django-rq/issues/421                     
  # https://github.com/netbox-community/netbox/issues/4633                                          
  - 'rq==1.3.0'

See #97 (comment) and 513bd4e

You can just specify netbox_pip_constraints locally for a quick fix. CI seems to have failed on Debian Stretch only with the above commit and I haven't gotten around to looking into why yet.

Even if I set this in my variables, it does not work:

netbox_pip_constraints:                                                                             
  # Blacklist pynacl 1.3.0 due to https://github.com/pyca/pynacl/issues/479                         
  - 'pynacl!=1.3.0'                                                                                 
  # Blacklist django-rq 2.3.1 due to https://github.com/rq/django-rq/issues/421                     
  # https://github.com/netbox-community/netbox/issues/4633                                          
  - 'django-rq!=2.3.1'

This is due to the version of django-rq used in the old version of netbox.
requirements.txt need to be changed with django-rq==2.3.2 instead of django-rq==2.2.0.

The issue is the same with a fresh install of 2.7.6 for example.

Weird, I only tested against 2.7.12 but it seemed to work against that.

What happens if you add a constraint for rq<1.4.0 instead?

Modifying the requirements.txt file with the role is not something I'm keen on doing in this role, as it causes conflicts in git-based deployments and idempotency issues for stable deployments.
