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....
