View changes of related objects (models.ForeignKey)

[arogachev]

I have Enterprise model and related ContactPerson and Phone models:

@reversion.register()
class Enterprise(models.Model):
    # ...

@reversion.register()
class ContactPerson(models.Model):
    enterprise = models.ForeignKey(Enterprise, on_delete=models.CASCADE)
    # Other fields

@reversion.register()
class Phone(models.Model):
    enterprise = models.ForeignKey(Enterprise, on_delete=models.CASCADE)
    # Other fields

In both backend and frontend, these related models are edited together with Enterprise using formsets. For example in admin I define inlines like this:

class EnterpriseAdmin(CompareVersionAdmin):
    inlines = [ContactPersonInline, PhoneInline]

Changes of related models are tracked with main model (for_concrete_model=True and it's True by default, I haven't changed it).

It would be great if in detail compare page I can see changes of each of these related models (including all fields) together with main model.

I see that extension has some support for viewing m2m relations changes, but can't find it for relations with models.ForeignKey.

Now the changes to related models are detectable only from change message and details - by manual comparing (opening one version in one browser tab, second one - in another and manually see what's changed in the forms).
