Exceptions when creating Custom Objects

[khangfem]

Plugin Version

0.2.0

NetBox Version

4.4.0-beta1

Python Version

3.10.12

Steps to Reproduce

1. Create new custom object type 'KEDB'
2. Create new custom object type field 'lesson' for 'KEDB'
3. Create new custom object of type 'KEDB'

Expected Behavior

A new custom object of type 'KEDB' be created

Observed Behavior

Server error: Field name lesson is not valid for model Table1Model in netbox_custom_objects.api.serializers.Table1ModelSerializer but still create a custom object of that type. When click on the custom object in list of "KEDB' it show: 'Server Error: 'Table1Model' object has no attribute 'lesson' "

@khangfem Thank you for opening a bug report. I was unable to reproduce the reported behavior on NetBox v4.4.0-beta1 and Custom Objects v0.2.0. Please re-confirm the reported behavior on the current stable release and adjust your post above as necessary. Remember to provide detailed steps that someone else can follow using a clean installation of NetBox to reproduce the issue. Remember to include the steps taken to create any initial objects or other data.

Is lesson type text field or a different field type?

[khangfem]

First I installed the plugin on Netbox v4.2.6 and learned that it can only run on v4.4.0-beta so i uninstalled the plugin, upgraded to v4.4.0-beta and installed the plugin, tried the above step and got the error. After that, I unistalled the plugin completely and dropped the old database, created a new one and ran the upgrade.sh again, installed the plugin back but still had the same error. I didn't add any other data, just added the custom object type and a field to it, created an object of the type. i confirm to have installed Netbox4.4.0-beta and Custom Object v0.2.0 and the type of lesson is text.

@khangfem I'm also unable to reproduce this, even after upgrading from a v4.2.6 installation. Could you please enable debugging (set DEBUG = True in configuration.py) and provide a complete stack trace of the error?

[khangfem]

@jeremystretch thank you for the reply but i don’t have access to the server now. I’ll do what you suggested and report back later. I’ve installed the plugin v0.1.0 on NetBoxv4.2.6 before and didn’t exprience any error. I check the database and saw that the type ‘KEDB’ is created in custom object table and the field ‘lesson’ in the custom object field table but there is no KEDB model table
