Inlines in the "forward direction" for OneToOneFields

Hello,

This is a tricky question that's been bothering me for over a year.

I'm working with french historians on a project called Dezède (source on github).  For several models they need to specify one or two "spatiotemporal coverage(s)": when and where something happened.  And sometimes they don't have exact dates|places, so they need CharFields to specify such approximations.  And sometimes they just have a date without a place, etc.

So I ended up with models similar to those you can find below.  (Sorry, it's a bit complex, but I promise it's simpler than the originals)

But this has a flaw.

When a user wants to specify Person.birth, he has to click on the magnifying glass, a popup opens with all the SpatioTemporalCoverages he can't choose (because of the OneToOneField), and he finally creates a new one.

That's awkward.

If he wants to modify it, it's even more complex, so that creating a new one is the best solution.

That's even awkwarder.

My question is therefore:

Is there a way to edit these SpatioTemporalCoverages directly from other admin change forms (Person, Work and Event)?

The closest solution I found is django-formfield.

Thanks!

# admin.py

from django.contrib.admin import ModelAdmin, site

from .models import *

    raw_id_fields = ('birth', 'death')

class WorkAdmin(ModelAdmin):

    raw_id_fields = ('creation',)

class EventAdmin(ModelAdmin):

    raw_id_fields = ('start', 'end')

site.register(Place)

site.register(SpatioTemporalCoverage)

site.register(Person, PersonAdmin)

site.register(Profession)

site.register(Author)

site.register(Work, WorkAdmin)

site.register(Event, EventAdmin)
