I found this little snippet on this group and am trying to get it to
work on my model, but no luck. I'm using the code pretty much as-is
except for two small changes, which are noted by a code comment. I can
create new instances of my model using this formset, bit I can't edit
existing instances (I haven't gotten to testing whether "deleting by
blanking" works yet). When I try to formset.save(), I get this error:
'RouteBaseForm' object has no attribute 'cleaned_data'
which is thrown on line 57 on that snippet. For some reason
cleaned_data isn't being defined. Anyone care to take a stab at
figuring out whats wrong? I don't know enough about the internals of
django to get to the bottom of this...
