allow filtering of changelogs by types of changes #13391
Description
NetBox version
v3.5.7
Feature type
Data model extension
Proposed functionality
An additional json field on the changelog model which contained a dict of true/false booleans for each model field to give high level info of what changes are in each changelog. This would allow for filtering of changelogs in a sane way (and scale across all the object types)
eg: for "device" model:
{
"name": true, # eg if name changed
"rack": false, # eg if assigned rack changed
"position": true, # eg if position in rack changed
"custom_fields": # if any of the custom fields changed value
}
when the changelog entry is being created it would loop through the pre/post changed json dicts and create true/false for each field depending on if the fieldcontent changed.
part of the migration could be to backfill in these changes (or add a command to do it, similar to the command which rebuilds the search cache)
Use case
right now there is no way to filter down changelogs on an object to specific types of changes.
by extending the changelog model with a "change_metadata" it could be possible to easily add filtering to the changelog views.
trying to do this by parsing the pre/post change fields is computationally expensive
Database changes
additional jsonb field for the change metadata
