Fix clean cache backend form method
Review Request #2927 — Created Feb. 27, 2012 and submitted
Fixed missing return statement in clean_cache_backend method which resulted in empty cache backend and an error accessing /admin page
settings.CACHE_BACKEND was None resulting in:
File ".../reviewboard/admin/views.py", line 33, in dashboard
'has_cache_stats': get_has_cache_stats(),
File ".../reviewboard/admin/cache_stats.py", line 37, in get_has_cache_stats
return get_memcached_hosts() != None
File ".../reviewboard/admin/cache_stats.py", line 25, in get_memcached_hosts
scheme, host, params = parse_backend_uri(settings.CACHE_BACKEND)
File ".../django/core/cache/__init__.py", line 59, in parse_backend_uri
if backend_uri.find(':') == -1:
AttributeError: 'NoneType' object has no attribute 'find'
Changing cache backend in admin interface works as expected.
