[Bug 1788631] Re: KeyError: 'used' security_group_rule quota missing 'used' key
Mark this as Won't Fix in horizon considering this only happens when the
deprecated neutron quota driver is used.

Title:
KeyError: 'used' security_group_rule quota missing 'used' key
Status in OpenStack neutron-api charm:
Fix Released
Status in OpenStack Dashboard (Horizon):
Won't Fix
Bug description:
On rocky rc1, after attempting to log in to the dashboard I hit:
Internal Server Error: /horizon/project/
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/django/core/handlers/exception.py", line 41, in inner
response = get_response(request)
...
File "/usr/lib/python2.7/dist-packages/openstack_dashboard/usage/views.py", line 163, in _process_chart_section
used = self.usage.limits[key]['used']
KeyError: 'used'
Full traceback: https://paste.ubuntu.com/p/RcMCjWs8HG/
From openstack_dashboard/usage/views.py:
def _process_chart_section(self, chart_defs):
charts = []
for t in chart_defs:
if t.quota_key not in self.usage.limits:
continue
key = t.quota_key
used = self.usage.limits[key]['used'] # <--- KeyError
quota = self.usage.limits[key]['quota']
Further debugging shows we're failing on key='security_group_rule'
chart_def=ChartDef(quota_key='security_group_rule', label=u'Security Group Rules', used_phrase=None, filters=None)
self.usage.limits[key]={'quota': 100}
Notice there's no 'used' key in self.usage.limits. Compare that vs
'security_group' which has:
chart_def=ChartDef(quota_key='security_group', label=u'Security Groups', used_phrase=None, filters=None)
self.usage.limits[key]={'available': 9, 'used': 1, 'quota': 10}
From openstack_dashboard/usage/quotas.py:
def tally(self, name, value):
"""Adds to the "used" metric for the given quota."""
value = value or 0 # Protection against None.
# Start at 0 if this is the first value.
if 'used' not in self.usages[name]:
self.usages[name]['used'] = 0
I haven't confirmed but it seems that tally does the initialization of
the 'used' key and for some reason that's not happening.
