2.问题解决:

改动/usr/share/openstack-dashboard/openstack_dashboard/dashboards/project/networks/subnets/tables.py源码例如以下

class CreateSubnet(SubnetPolicyTargetMixin, CheckNetworkEditable,
                   tables.LinkAction):
    name = "create"
    verbose_name = _("Create Subnet")
    url = "horizon:project:networks:addsubnet"
    classes = ("ajax-modal",)
    icon = "plus"
    policy_rules = (("network", "create_subnet"),)

    def get_link_url(self, datum=None):
        network_id = self.table.kwargs[‘network_id‘]
        return reverse(self.url, args=(network_id,))

    def allowed(self, request, datum=None):
        usages = quotas.tenant_quota_usages(request)
        if usages[‘subnets‘].get(‘available‘, 1) <= 0:
            if ‘disabled‘ not in self.classes:
                self.classes = [c for c in self.classes] + [‘disabled‘]
                self.verbose_name = _(‘Create Subnet (Quota exceeded)‘)
        else:
            self.verbose_name = _(‘Create Subnet‘)
            self.classes = [c for c in self.classes if c != ‘disabled‘]

        return True


[BUG] Dashboard报错:if usages['subnets']['available'] &lt;= 0: KeyError: 'available'
