Issue type: bug report

Python version:
2.7.6
NetBox version:
1.9.0

  1. Open device
  2. Click green "connect" + button next to interface
  3. Type name of device in search and select from list
  4. Select interface from dropdown
  5. Click "Connect" button

I'm returned to the same page.

If I click "connect" again (fields above still populated with same data), I get this:
ValueError at /dcim/devices/6/interface-connections/add/
invalid literal for int() with base 10: ''
Request Method: POST

If I click "cancel" instead at that step, I'm returned to the same device but don't see the connection I attempted made.

Same error/behavior. Issue only happened after upgrade to 1.9.0.

Python Version:2.7.5
NetBox Version: 1.9.0

Steps to reproduce:

1)Go to any device
2)Click on add interface connection to any interface. URL goes to: /dcim/devices/489/interface-connections/add/?interface_a=874
3)Choose B side device and interface.
4)Click Connect. Connection does not add, and URL changes to: /dcim/devices/489/interface-connections/add/ (same page as above with devices filled out, however URL changes)
5)Click Connect again, and get the same error. (traceback listed below):
