Presently, there's not a way without altering models to be able to have
inline models if dependencies are declared on the "owning" class. Allow me
to explain with code:
class Person(models.Model):
address = models.OneToOneField("Address")
class Monument(models.Model):
address = models.OneToOneField("Address")
class Sighting(models.Model):
address = models.OneToOneField("Address")
class Address(models.Model):
name = models.CharField(...)
street_address = models.CharField(...)
The goal with this code is that a `Person` owns an `Address` like a
`Monument` owns an `Address` like a `Sighting` owns an `Address`. There's
really no reason for an `Address` to know of itself what it is owned by, it
could be owned by multiple different objects. The lookup needs to happen
from the owner.
When attempting to make inlines for these types of relations, an error is
thrown:
class AddressInline(admin.TabularInline):
model = Address
fields = ('street_address',)
class SightingAdmin(admin.ModelAdmin):
inlines = (AddressInline,)
Here's the error which is thrown by a *similar* real example:

IMHO, inlines should work regardless of which side the relationship is
declared on. Can I submit this for a feature request?
