# Netbox artifcats
from extras.scripts import Script, ObjectVar, MultiObjectVar
from dcim.models import Site, Device

# Modules

# Classes
class DevicePing(Script):
    class Meta:
        name = "Ping devices"
        description = "A simple script to ping devices in a selected location"
        field_order = ("site", "devices")

    site = ObjectVar(
        model=Site
    )

    devices = MultiObjectVar(
        model=Device,
        query_params={
            "site_id": "$site"
        }
    )

    def run(self, data, commit) -> str:
        #print_in_nb = []

        self.log_debug('run')
        try:
            from icmplib import ping

            for device in data["devices"]:
                self.log_debug(f"{device.name} current status is {device.status}")

                if 'icmplib' in sys.modules:
                    self.log_debug("The 'icmplib' is loaded.")
                    result = ping(str(device.primary_ip.address.ip), count=3, interval=0.2, privileged=False)
                else:
                    self.log_debug("The 'icmplib' is not loaded.")
                    result = lambda: None
                    result.is_alive = True

                if result.is_alive:
                    device.status = "active"
                else:
                    device.status = "offline"

                device.save()

                self.log_info(f"{device.name} is set to {device.status}")

                # print_in_nb.append(f"{device.name} is set to {device.status}")
        except Exception as ex:
            self.log_failure(f'{type(ex).__name__}: {ex}')
            self.log_debug(sys.modules)


        # return '\n'.join(print_in_nb)
        return 'Done'
