Need help with Custom Script and Interface Template Filtering

[heidl89]

Hi.

I want to filter Interface Templates by Device Type.

Does anybody know wheres my fault at filter query?

        self.log_debug(device.device_type.interface_template_count)
        #works
        data = InterfaceTemplate.objects.all()
        #works

        data.filter(device_type = device.device_type)
        #Exception:  QuerySet indices must be integers or slices, not str.

        for e in data:
            self.log_debug(e.device_type)
        #works -> all device_type are shown in log

why don't you use
device.device_type.interfacetemplates.all() to get all the interfacetemplates that device_type has directly?

anyway, your filtering should work just fine. I just did some tests on my netbox and it works like it should in nb-shell:
`>>> device = Device.objects.get(name='')

intf_templates = InterfaceTemplate.objects.all()
len(intf_templates)
1278
intf_templates = InterfaceTemplate.objects.filter(device_type = device.device_type)
len(intf_templates)
57`

what version of netbox are you using?
