How to post change to Custom Field - DropDown Menu

[Luis N]

I can pull requests from netbox using curl in some of my bash scripts but when trying to post a change or update, it says 

  "detail": "Method \"POST\" not allowed."

Using Python 3.5.2 and Netbox 2.4.4 on Ubuntu

curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=2" --data '{ "custom_fields":, "Requested":, "value": 6,  "label": Yes }' 'http://netbox01/api/dcim/devices/5/'

POST is for creating new objects, e.g. through /api/dcim/devices/.

Use PATCH for updating existing devices (e.g. /api/dcim/devices/5/).

Getting closer, I now get "detail": "JSON parse error - Expecting value: line 1 column 19 (char 18)"

I was able to fix the format of the payload, now get this

The complete exception is provided below:

<class 'TypeError'>

int() argument must be a string, a bytes-like object or a number, not 'dict'

updated it to 

'{"custom_fields": {"Requested": {"value": "6","label": "Yes"}}}'

[Luis N]

Custom fields, can we even edit them via API ?? Anyone ? I am able to update serial #, etc not custom fields

[Luis N]

Really frustrating here that I cannot find a doc specifying how to change the custom field value for a selection via the API.

I having update custom list field using pynetbox though those accept only int value of those list item which can only be obtained from html render page . 

something linke this in my code. 

_device_instance.custom_fields['dev_discovery_status'] = int(dev_discovery_status)

[Amit]

curl -X  PATCH -H "Content-Type: application/json" -H "Authorization: Token <MYTOKEN >" -H "Accept: application/json; indent=2" --data '{ "custom_fields" : { "dev_discovery_status": 17 }}' http://MYNETBOX/api/dcim/devices/71/

This will work for you. 

curl -X POST -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=2" --data '{ "custom_fields": { "Requested": 6 }}' http://netbox01/api/dcim/devices/5/

Corrected Typo

curl -X PATCH -H "Content-Type: application/json" -H "Authorization: Token <TOKEN>" -H "Accept: application/json; indent=2" --data '{ "custom_fields": { "Requested": 6 }}' http://netbox01/api/dcim/devices/5/

Hello all,

I have the same issue, trying to patch a device via API. Just as with you, it's only for custom fields, and for me it's happening for Choice custom fields.

The setup

NetBox: v2.4.3

Python: 2.7.5

OS: RHEL 7.5

Here's the JSON excerpt for changing those 2 custom field values:

{
"custom_fields":
  {
        "pci_device": {
            "value": 2,
            "label": "No"
        },
        "environment_tag": {
            "value": 7,
            "label": "PROD"
        },
  }
}

Or, transalated into CURL synthax:

curl -X PATCH "https://netbox.lab.local/api/dcim/devices/117/" -H  "accept: application/json" -H  "Content-Type: application/json" -H  "X-CSRFToken: c3zB2CUw4ElGLpfl7upPtG4VpKbB5qnq4" -d "{\"custom_fields\":  {        \"pci_device\": {            \"value\": 2,            \"label\": \"No\"        },        \"environment_tag\": {            \"value\": 7,            \"label\": \"PROD\"        },        \"tech_owner\": \"TDB\"  }}"

The error I get is:

<class 'TypeError'>
int() argument must be a string, a bytes-like object or a number, not 'dict'

What am I doing wrong?

Regards,

Igor

Don't send a dict of the value and the label, the API only needs to know the value, it cares nothing about the label when you are trying to change data.

So your payload should simply be:

{
"custom_fields":
  {
        "pci_device": 2,
        "environment_tag": 7,

Thank you kindly for the advice, it works! And so much simpler.

Regards,

Igor
