Hi,
First let me say I've looked at documentation, but feel a bit dyslexic
when it comes to this stuff.
The situation: I have three tables: a service provider table with
city, state abbreviation and country abbreviation (among other other
info), a states table with state names, abbreviations, and other state
info, and a country table with country names, abbreviations and other
country info. I want an output like:
_______________________
FULL COUNTRY NAME
Full State Name
City..... Provider
Provider
City..... Provider
Full State Name
City..... Provider
Provider
City..... Provider
FULL COUNTRY NAME
_______________________
I only want Country and State headings for countries and states having
providers. Experimenting at the shell, it appears my model is okay:
_________________________________________________
>>> from mhd.models import *
>>> countries = Country.objects.filter(iso2__in=["US","CA"]).distinct()
>>> countries
[<Country: Canada>, <Country: United States of America>]
>>> countries[0].state_set.all()
[<State: Alberta>, <State: British Columbia>, <State:
Manitoba>, ...]
>>> countries[1].state_set.all()
[<State: Alabama>, <State: Alaska>, <State: Arizona>, ...]
>>> countries[1].state_set.all()[1]
<State: Alaska>
>>> countries[1].state_set.all()[1].provider_set.all()
[<Provider: Anne B. ... PsyS, LPC None>]
>>> countries[1].state_set.all()[1].provider_set.all()[0]
<Provider: Anne B. ... PsyS, LPC None>
>>> countries[1].state_set.all()[1].provider_set.all()[0].practitioner
u'Anne B. ... PsyS, LPC'
>>> countries[1].state_set.all()[1].provider_set.all()[0].city
u'Anchorage'
_________________________________________________
For the next 5 days, a whittled down version of what I thought I was
trying to do lives on dpaste.com:
http://dpaste.com/32704/ model.py
http://dpaste.com/32755/ views.py
http://dpaste.com/32706/ listings.html template
However my later experiments in the manage.py shell (above) lead me to
suspect maybe I'm bass-ackwards about the whole thing. Unfortunately,
suspecting that is still not enough to get me where I'm trying to go.
Help?
Thanks.
