google maps - Django (Geo) Geocode - geocode on model save not working -


i've got save override on model:

    def save(self, **kwargs):     if not self.location:         address = u'%s %s %s %s' % (self.address_first, self.address_second, self.address_third, self.postcode)         geocoder = nominatim()         try:             _, latlon = geocoder.geocode(address)         except (geopyerror, valueerror):             pass         else:             latlon = geocoder.geocode(address)             point = 'point({0} {1})'.format(latlon[1][1], latlon[1][0])             self.location = geos.fromstr(point)     super(venue, self).save()

i getting

typeerror: 'nonetype' object not iterable

specifically on address variable. works fine if hardcode address in.

i assume it's fact self.address... not available until after model has saved? what's best way this? save twice?

thanks

updated in case else has issue. google expecting api requests have address in such format line1+line2+line3+zipcode, rather line1, line2, line, zipcode etc etc. format string before try , geocode. it's not django/python specific.

def save(self, **kwargs):     if not self.location:         address = u'{0}, {1}, {2}'.format(self.address_second, self.address_third, self.postcode)         address = address.replace(" ", "+").replace(',', '')         geocoder = googlev3()         try:             _, latlon = geocoder.geocode(address)         except (geopyerror, valueerror):             pass         else:             latlon = geocoder.geocode(address)             point = 'point({0} {1})'.format(latlon[1][1], latlon[1][0])             self.location = geos.fromstr(point)     super(venue, self).save()

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
