def index(request):
    try:
        jails = iocage.Jails()
        jail = iocage_lib.ioc_list.IOCList()
        print(jails[0].running)
        print(jail.list_datasets())
    except (Exception, SystemExit):
        raise Http404("Jails does not exist")
    return render(request, 'jails/index.html', {'jails': jails })

def start(request):
    try:
        response = json.loads(request.body)
        jail = iocage.Jail(response['jail_name'])
        jail.start()

    return HttpResponse('OK')

def stop(request):

Jail State lookup is an expensive operation (using subprocess.Popen to call jls). When you suspect not to be the sole jail manager, consider updating the global jails state or an individual jails state as such:

import ioc
jail = ioc.Jail("myjail")
print(jail.running)
# .. something happened in between
jail.state.query()
print(jail.running)

import ioc
jails = ioc.Jails()
print(jails[0].running)
# .. something happened in between
jails.states.query()
print(jails[0].running)

Please note that during your Issue the package module namespace changed from iocage to ioc.
