I'm stuck on creating a custom widget for the admin interface and
wondering if anyone can help on where to look.
I've got a field which is essential a ForeignKey pointing to a State
model. In the admin interface I would like to show the current state
(done) and a list of the possible transitions (where I'm stuck). The
list of the possible transitions is the issue since this is based on
the attributes of the current State AND the current values of the
model instance.
On the state I've got a method:
def get_transitions(self, obj):
...
Which given the model instance, will combine and figure out the
possible transitions. But I'm not sure how to get the required object.
I've been rummaging around in
django.db.models.fields.related.ForeignKey > formfield, there's an
option to set the queryset. For example for a foreign key, it uses the
default object manage of the class the reference is pointing to. But
at that point I don't have the model instance to pass to
get_transitions.
If I go up to the widget I don't have access to the model instance at
all.
I've wandered around object managers and I'm a bit stumped. Any ideas
appreciated, I have a feeling I'm going about it all wrong (wouldn't
be the first or last time :).
Thanks
