Hi,
Right, I think I got that far. But when I try to add it to data store,
I get the following error.... GeoPtProperty is supposed to take GeoPt
data type, which is "geographical point represented by floating-point
latitude and longitude coordinates." But it doesn't say whether it
needs to be a list or tuples... Any help would be much appreciated.
Thank you in advance!
File "C:\Program Files\Google\google_appengine\google\appengine\api
\datastore_types.py", line 596, in __init__
(lat, typename(lat), lon, typename(lon)))
BadValueError: Expected floats for lat and long; received
(37.3096785453849 (a unicode) and (a unicode).
And in my python code looks like this...
class LocationInfo(db.Model):
geocode = db.GeoPtProperty()
equip = db.ListProperty(long)
rating = db.RatingProperty()
class AddLocation(webapp.RequestHandler):
def post(self):
loc = LocationInfo()
loc.geocode = self.request.get('latlng')
loc.put()
self.redirect('/')
And my javascript looks like this....
GEvent.addListener(map, "click", function(overlay, point) {
if (marker) {
map.removeOverlay(marker);
}
var iwform = '<form action="\addDB" method="post">'
+ "<input type=\"hidden\" name=\"latlng\" value="+point+">"
+ '<label for="place">Name:</label><input id="id_place"
type="text"
name="place" size="15" value=""/><br />'
+ '<input type="submit" value="Save"/>'
+ '</form>';
var marker = new GMarker(point,{draggable:true});
map.addOverlay(marker);
map.openInfoWindowHtml(point, iwform);
}
