Hi,
Is there a way to access an existing database schema in Django?
Any help would be appreciated!

You can use the inspectdb option of the project manager, you will find 
more information in the official documentation :

Re: Possible to do location detection?

 Hello,

I'd like to detect the location of each user and then set the default
language and location for him accordingly. The homepage would also be
tailored to each location (country and city).

Can anyone share information on how to do that with Django?


You can use geoip with geodjango :

Re: Django point field

2009-09-25 Thread Nabil Servais 

Hello,

I use json for output instead of cvs, and it works. Also I convert the 
lattitude and longitude into float.

enjoy

def get_lat_long(location):
 key = settings.GOOGLE_API_KEY
 output = "json"
 location = urllib.quote_plus(location)
 request = 
"http://maps.google.com/maps/geo?q=%s&output=%s&key=%s 
" % (location, 
output, key)
 data = urllib.urlopen(request).read()
 dlist = simplejson.loads(data)
 if dlist['Status']['code'] == 200:
 lat = float(dlist['Placemark'][0]['Point']['coordinates'][0])
 long = float(dlist['Placemark'][0]['Point']['coordinates'][1])
 return (lat, long)
 else
 return ''

Re: Django point field

2009-09-25 Thread Nabil Servais 

Hello,

I solve your probleme in changing the output format into json, then I
convert the coordinates into Float.

def get_lat_long(location):
key = ''
output = "json"
location = urllib.quote_plus(location)
request = "http://maps.google.com/maps/geo?q=%s&output=%s"; %
(location, output)
data = urllib.urlopen(request).read()
dlist = simplejson.loads(data)
lat = float(dlist['Placemark'][0]['Point']['coordinates'][0])
lon = float(dlist['Placemark'][0]['Point']['coordinates'][1])
if dlist['Staut']['code'] == 200:
return (lat,lon)
I've tested and it works. Good luck
