Hi Rob,
aehm, maybe what you were looking for was this:
@json_response
def send_toxids_list(request):
ret = Toxid.objects.all()
return to_dojo_data(ret, identifier='docno')
the json_response decorator takes care of extrcting only the
fields form the model, you dont have to do this
by hand. And the to_dojo_data() function converts the
data into a dojo.data store compatible format.
See also this blog post about more info
about the json_response decorator/function
and insight details.
