How can I generate a Django Admin URL with preselected objects and a default action?

I want to create a link that directs users to a Django Admin page for a specific model, with certain objects already selected and a dropdown action pre-filled.

I've tried the following code:

PYTHONCopied
def get_admin_action_link(record, action):
    app_label = record._meta.app_label
    model = record._meta.model_name
    id = record.id
    env = f"{settings.env}.myurl.com" if settings.env else "http://localhost:8000"
    return f"{env}/admin/{app_label}/{model}?action={action}&_selected_action={id}"

The generated link is:

PLAINTEXTCopied
http://localhost:8000/admin/app/mymodel?action=process&_selected_action=591

However, when clicking the link, it only navigates to the model's changelist view in the admin. The objects are not pre-selected and the action is not applied as expected.
