How track changes of a Model that is only included as an Inline and nowhere else (Reverse Foreign Key)

[raayu83]

Hello,

I have a questions regarding History management in a ModelAdmin that includes an One to Many Inline:
How do you set these up so that History of the Many side model is also shown on the main Model, in a similary way to ManyToMany Models?
I have two related Models: One for Reports, one for the E-Mail Addresses the Reports are to be sent to.

Basically they are set up like this:

class DeliveryByEmailRecipient(TimestampMixin, models.Model):
    report = HistoricForeignKey(
        "Report",
        related_name="delivery_by_email_recipients",
    )
    history = HistoricalRecords()

class Report(TimestampMixin, CloneMixin, models.Model):
    name = models.CharField(max_length=255)
    history = HistoricalRecords()

I've integrated the DeliveryByEmailRecipient Model into the Reports Admin page using an InlineAdmin.
Administration of the E-Mails works as intended, but changes are not tracked by simple-history.

I've probably an error in my setup, so I would be grateful if somebody could give me some hints.

I'm actually not even sure if I need to use HistoricForeignKey here.

Best regards
