Originally created by @danshipt on GitHub (Aug 8, 2018).

Environment

  • Python version: 3.4.8
  • NetBox version: 2.4.1

Steps to Reproduce

  1. Create device with number of interfaces
  2. Add connections to this interfaces

Expected Behavior

ALL created interfaces are shown with or without connection info.

Observed Behavior

Some interfaces are missing.

Here is what i found.

  1. DeviceView got all available interfaces and put it into template - OK
  2. In device.html i've put line DBG1 - {{ iface }} before {% include 'dcim/inc/interface.html' %}
  3. In inc/interface.html i've put DBG - {{ iface }} in the very beginning of the file.

Here is the results:

DBG1 - Bridge-Aggregation1 DBG - Bridge-Aggregation1 DBG1 - GE1/0/1 DBG - GE1/0/1 DBG1 - GE1/0/2 DBG - GE1/0/2 DBG1 - GE1/0/3 DBG - GE1/0/3 DBG1 - GE1/0/4 DBG - GE1/0/4 DBG1 - GE1/0/5 DBG - GE1/0/5 DBG1 - GE1/0/6 DBG - GE1/0/6 DBG1 - GE1/0/7 DBG - GE1/0/7 DBG1 - GE1/0/8 DBG - GE1/0/8 DBG1 - GE1/0/9 DBG - GE1/0/9 DBG1 - GE1/0/10 DBG - GE1/0/10 DBG1 - GE1/0/11 DBG - GE1/0/11 DBG1 - GE1/0/12 DBG - GE1/0/12 DBG1 - GE1/0/13 DBG - GE1/0/13 DBG1 - GE1/0/14 DBG - GE1/0/14 DBG1 - GE1/0/15 DBG - GE1/0/15 DBG1 - GE1/0/16 DBG - GE1/0/16 DBG1 - GE1/0/17 DBG - GE1/0/17 DBG1 - GE1/0/18 DBG - GE1/0/18 DBG1 - GE1/0/19 DBG1 - GE1/0/20 DBG - GE1/0/20 DBG1 - GE1/0/21 DBG - GE1/0/21 DBG1 - GE1/0/22 DBG - GE1/0/22 DBG1 - GE1/0/23 DBG - GE1/0/23 DBG1 - GE1/0/24 DBG - GE1/0/24 DBG1 - GE1/0/25 DBG1 - GE1/0/26 DBG - GE1/0/26 DBG1 - GE1/0/27 DBG - GE1/0/27 DBG1 - GE1/0/28 DBG - GE1/0/28 DBG1 - GE1/0/29 DBG - GE1/0/29 DBG1 - GE1/0/30 DBG - GE1/0/30 DBG1 - GE1/0/31 DBG - GE1/0/31 DBG1 - GE1/0/32 DBG1 - GE1/0/33 DBG1 - GE1/0/34 DBG - GE1/0/34 DBG1 - GE1/0/35 DBG - GE1/0/35 DBG1 - GE1/0/36 DBG - GE1/0/36 DBG1 - GE1/0/37 DBG - GE1/0/37 DBG1 - GE1/0/38 DBG1 - GE1/0/39 DBG - GE1/0/39 DBG1 - GE1/0/40 DBG1 - GE1/0/41 DBG - GE1/0/41 DBG1 - GE1/0/42 DBG - GE1/0/42 DBG1 - GE1/0/43 DBG - GE1/0/43 DBG1 - GE1/0/44 DBG - GE1/0/44 DBG1 - GE1/0/45 DBG - GE1/0/45 DBG1 - GE1/0/46 DBG - GE1/0/46 DBG1 - GE1/0/47 DBG - GE1/0/47 DBG1 - GE1/0/48 DBG - GE1/0/48 DBG1 - GE1/0/49 DBG - GE1/0/49 DBG1 - GE1/0/50 DBG - GE1/0/50 DBG1 - GE1/0/51 DBG - GE1/0/51 DBG1 - GE1/0/52 DBG - GE1/0/52

Note that for example interface GE1/0/19 have only DBG1 - GE1/0/19 record. It means that {% include 'dcim/inc/interface.html' %} is not working for some reason.

It was Reverse for 'device' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['dcim/devices/(?P<pk>\\d+)/$'] error on include in inc/interface.html <a href="{% url 'dcim:device' pk=connected_iface.device.pk %}">{{ connected_iface.device }}</a>

Please provide the exact data someone else can use to reproduce this error, starting with creating a new device.

@jeremystretch This behaviour is related to improper (?) use of API and this error appears when Interface.connected_interface.device returns None. This is only happens when Interface objects are created without device (device property is None). In this case template rendering fails.

I think it is a good idea to add additional check to Interface::clean method. This prevents occasional flooding with unrelated Interface objects.

Again, you'll need to prescribe the exact steps needed to reproduce the bug on a fresh installation. Otherwise no one will be able to address this.
