Similar to get_or_create, I would like to be able to update_or_create in Django.
Until now, I have using an approaching similar to how @Daniel Roseman does it here. However, I'd like to do this more succinctly as a model method.
This snippet is quite old and I was wondering if there is a better way to do this in more recent version of Django.

There is update_or_create, eg::
obj, created = Person.objects.update_or_create(
first_name='John', last_name='Lennon',
defaults={'first_name': 'Bob'},
)
# If person exists with first_name='John' & last_name='Lennon' then update first_name='Bob'
# Else create new person with first_name='Bob' & last_name='Lennon'
See QuerySet.update_or_create (new in Django 1.7dev)
