Django point field

[please smile]

Hi all,
    I have a problem to convert latitude and longitude values into point field value.
   
   
    def get_lat_long(location):
        key = settings.GOOGLE_API_KEY
        output = "csv"
        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 = data.split(',')
        if dlist[0] == '200':
            #return "%s, %s" % (dlist[2], dlist[3])
            return (dlist[2], dlist[3])
        else:
            return ''
       
       
    My models.py
    --------------
    class Person(models.Model):
        address = models.CharField(_('address'), max_length=200, blank=True)
        city = models.CharField(_('city'), max_length=100, blank=True)
        state = USStateField(_('state'), blank=True)
        zipcode = models.CharField(_('zip code'), max_length=5, blank=True)
        point = models.PointField(blank=True, null=True)
       
        objects = models.GeoManager()
       
       
       
        def save(self, force_insert=False, force_update=False):
       
        if self.point == None:
            location = "%s+%s+%s+%s" % (self.address, self.city, self.state, self.zipcode)
            point_lat, point_long = get_lat_long(location)
            pnt = Point(point_long, point_lat)
            self.point = pnt
 
Here I convert latitude , longitude value into point field value. But i am getting   "Exception Value: Invalid parameters given for Point initialization."        
   
please advise...
Thank you....

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
<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 ''

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

Thanks a lot Nabil servais. its works for me too....
