Dynamic form fields based on user input for custom scripts

[Ikke]

Environment

• Python version: Example: 3.6.9
• NetBox version: Example: 2.8.5

Proposed Functionality

This is a continuation of #3766, which asked about being able to filter form fields based on the input of other form fields.

One point that was not addressed as this comment. From what I could find, it is not possible to dynamically adjust the query used for a field based on what value is selected in another field.

I found that APISelect widget has a parameter called conditional_query_params, which seems to come pretty close, but as far as I can see you cannot use that to adjust the actual query values, only add static conditions based on another condition.

So it would be nice if we could refer to the selected value from another field, and use that value in the query params.

Something like

site = ObjectVar(
    description = "Site",
    queryset = Site.objects.all()
)

prefix = ObjectVar(
    queryset = Prefix.objects.all(),
    widget = APISelect(
        api_url="/api/ipam/prefixes/",
        dynamic_query_params={
            'site': 'site_id={{id}}'
        },
        display_field='prefix'
    )
)

Use Case

Same as #3766

For example: Have a form where you first select a site, and then select a prefix within that site.

APISelect is not part of NetBox's public API, and is not intended for consumption outside the core code base. It is subject to change at any time, without warning, and your scripts which use it are very likely to break when upgrading to a future release.

Please revise your issue to on the specific functionality you are proposing, without invoking components from outside the documented API for custom scripts.
