Re: 'NoneType' object has no attribute 'datetime' bug?

[dobrysmak]

Thank's for help , i did this and now i've got this 

AttributeError at /wejdz-do-gry/76/
'NoneType' object has no attribute 'now'

This is strange because the shell import works fine but the server script 
throus an exception.

>>> from datetime import datetime, time, date
> >>> print datetime.now()
> 2012-07-14 14:14:17.897023
> >>> print datetime.combine(date.today(),time(19,30))
> 2012-07-14 19:30:00
> >>> 
>
Ok, that's true but the script does not even reach the 'combine' function 
it died on 'now'.

'NoneType' object has no attribute 'datetime' bug?

[dobrysmak]

Hi guys,
i have run into this.

Traceback:
File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" 
in get_response
111. response = callback(request, *callback_args, **callback_kwargs)

File "/home/user/dev/xyz/coupon/views.py" in enter_game
69. Coupon(coupon=coupon, player=player, credicts=credicts).save()
File "/home/user/dev/xyz/coupon/models.py" in save
253. self.coupon.close_coupon()
File "/home/user/dev/xyz/coupon/models.py" in close_coupon
78. current_date = datetime.datetime.now()

Exception Type: AttributeError at /wejdz-do-gry/49/
Exception Value: 'NoneType' object has no attribute 'datetime'
Request information:
GET: No GET data

and the cuntion "close_coupon" looks like this

class Coupon(models.Model): .
.
. end_date = models.DateTimeField(default=None, null=True, blank=True) 
def close_coupon(self):
current_date = datetime.datetime.now() today = 
datetime.datetime.combine(datetime.date.today(), datetime.time(19,30))
.
  .
end_date = current_date

Don't know if that's a bug. Does anyone know how to deal with this issue? 
Cheers!

Re: tornadio2 cached results

[dobrysmak]

Figured out that tornadio2 or tornado is somehow keepeing django's orm data 
in memory pulling that same data on each db request.
When i'm reffering to mysql database via  python MySQLdb, making connection 
each request. i'm getting updated results, that's ok. 

How to force tornadio2/tornado to get the updated data from db via django?

tornadio2 cached results

[dobrysmak]

Hi, 
i'm running tornadio2 server with socket.io and i run into a problem, when 
i'm getting some data from db via django's orm the socket server doesn't 
want to get new fresh data from db, every time the event occurs. He's just 
keeping the same data from begging.
Does anyone had same problem?

Bye.

using django with socketio

[dobrysmak]

Hi guys,
long story short, i'm using* django-socketio* with my app on nginx + uwsgi 
+ tcp_module  and i 
cant get it to work with the browser on production server.
Here's short conf  

Any ideas how to get it to work? or is there other way to use socket.io 
(besides 
Noje.js) with Django framework?
Cheers!
