Saving data in django model don't actually saves - django

Question

How should I understand this? And how this can happens?
Go into django shell:
>>> from customauth.models import Profile
>>> p = Profile.objects.get(user_id=1)
>>> p.status
u'34566'
>>> p.status = 'qwerty'
>>> p.status
'qwerty'
>>> p.save()
>>> p.status
'qwerty'
>>> p = Profile.objects.get(user_id=1)
>>> p.status
u'qwerty'
>>>
Exit and go into django shell again:
>>> from customauth.models import Profile
>>> p = Profile.objects.get(user_id=1)
>>> p.status
u'qwerty'
>>>
Everything seems OK. But go into dbshell now:
mysql> select user_id, status from customauth_profile where user_id=1;
+---------+--------+
| user_id | status |
+---------+--------+
| 1 | 34566 |

Answer 1

I was having the same problem, I'm using Django and Mongo... the data wasn't persisted after object.save()... Them, I used it to solve:
object.save_base(force_update=True)
Now is working for me, hope can help.

Answer 2

If the data persists after closing the shell, it is very unlikely that the data was not saved into the database. Can you check your settings.py and make sure you're saving to the correct mysql database ?

Answer 3

The shell session is a single database transaction. Connections outside that won't see the changes, because of transaction isolation. You'll need to commit the transaction - the easiest way would be to quit the shell and restart.
In a normal request, Django commits automatically at the end of the request, so this behaviour isn't an issue.

Problem was in caching module. Strange, but there is no caching middleware was plugged and cache doesn't used in saving methods.
Was used django.core.cache.backends.locmem.LocMemCache module, may be its broken or has some strange features, I don't know. Will try memcached module, it should (I wish) fix problem without swithing off cache on site.
