Support filter lookups for custom fields #6615
Description
NetBox version
v2.11.6
Feature type
Change to existing functionality
Proposed functionality
Extend NetBox's filtering functionality to automatically generate lookup filters for a model's custom fields. For example, a custom field named foo applied to the dcim.Site model will result in a filter named cf_foo on SiteFilterSet. This filter will support either an exact match or an icontains lookup, depending on how the CustomField is configured. However, it will not support any further lookup logic, such as greater/less than evaluation for integers.
Implementing this feature would comprise automatically generating appropriate lookups for a custom field depending on its type. For example, integer fields should get __lt, __lte, __gt, __gte, and similar lookups. This might be done by extending either BaseFilterSet or the CustomFieldFilter class,
Use case
This extension of the existing filtering logic would enable users to filter on custom fields with the same degree of flexibility afforded to built-in model fields.
