Why do you want to do this only in the admin interface?
Its a generic thing: every time you save/change a period you should set the
end-date of the previous one. So I would do this with a post-save hook (aka
signal) directly in the models.py. Or maybe even subclass your models save-
operation.
This is a question not a competing opinion.
Why would you use a post-save signal? Why not just override save() and
use the model manager directly to find the previous period and if it
doesn't have and end date pop one in?
Thanks
