Use of InlineFields for better forms with custom scripts

[Domundy]

Hey

I will try to use InlineFields for better custom scripts forms, as proposed here and here

I tried different ideas for example.

from extras.scripts import *
from dcim.models import DeviceType, Device, Interface, Cable, Module, ModuleBay
from ipam.models import VRF, Prefix, IPAddress, VLAN
from utilities.exceptions import AbortScript
from utilities.forms.rendering import *



class CreateCable(Script):
    class Meta:
        name = "Create Cable"
        description = "Erstellt ein Kabel zwischen zwei Interfaces."
        commit_default = True
        scheduling_enabled = False


        fieldsets = (
                (('Device 1'), ('device_type_1', InlineFields('device_1', 'device_1_interface'))),
        )

or as shown here

fieldsets = (
    (_('Dimensions'), (
        'type', 'width', 'u_height', InlineFields('outer_width', 'outer_depth', 'outer_unit'),
    )),
)

but none of this does work in Custom Scripts

Any new idea?

I use v4.1.3
