Unless I'm mistaken it should be fairly simple in this case to create
your own set of templates for each of the django apps you're using and
then have them output the data you need as json text instead of as
html

Re: trouble with yesno to generate images

[Malinka Rellikwodahs]

This is just a quick guess without really knowing anything about the
yesno filter, but I would try single quotes inside the html in your
yesno filter

Re: Automatically Generating Non-Ajax Client-Side Form Validation

[Malinka Rellikwodahs]

following you're link they discussed client side form validation just
like you mentioned, not sure it's complete or what you need but
http://eikke.com/tag/django-validation/ might have some useful
information

Re: Shouldn't blank=True imply null=True?

not sure if django supports binary data or any form of arrays but in
those cases it could make sense to have blank=True and null=False,
because you could have for whatever reason a situation where you'd
have an array of zero length which afaics is the same as an empty
string, and could have a requirement outside of django to allow those
values but not allow nulls

yes you should be able to in django do anything you can do in python

excluding the template language obviously that isn't python

Sorry for the late response, due to other issues this got pushed down
in the priority list here, but here is some code examples of how I'm
retrieving my data etc.

views.py (cropped for index):

from django.views.decorators.cache import never_cache
from django.shortcuts import render_to_response
from django.http import Http404
from Client import GetClients

@never_cache
def index(request):
clients = GetClients()
pend = [cl for cl in clients if len(cl.Stops()) != 0 or 
len(cl.Limits()) != 0]
pos = [cl for cl in clients if cl.Position() != 0 or not cl.MatchPos()]
return render_to_response(
'Clients/index.html', {
'ReloadRate': 120,
'pending': pend,
'position': pos,
}
)

Client.py (cropped for GetClients):

from MySQLdb import connect

def GetClients():
avail_db = 
connect(user=AVAIL_USER,db=AVAIL_DB,host=AVAIL_HOST,port=AVAIL_PORT)
c = avail_db.cursor()
c.execute("SELECT acct_pk FROM t_acct")
return [Client(cl[0]) for cl in c.fetchall()]

where the Client object is a series of functions and private data that
gets pulled from the DB either on construction or on request depending
on how troublesome it is to get from the DB

now like I said before I've ran the code to get the data from the DB
outside of django and it gets the data on request fine w/o being
outdated, it's just when i use django to get html out of the data
