Re: Question about customizing Django's session backend.

[Начаров Михаил]

Hi Chen.

There are several session backends in django: database, cached, 
file-based. You can read about them on this page 
. But I 
didn't see obstacles for using default django configuration. You can use 
django models for django contrib application, while in your own apps 
still using sqlalchemy.


Cheers!

Hi everyone,
I am wondering if there is a way to customize django's session backend 
like we can do it for user authentication backend, the reason why I 
ask this is that when I call django.contrib.auth.login, it gives me 
the error no django_session table since I am using sqlalchemy, I did 
not do python manage.py syncdb at all.


Thanks in advance.

Re: ImproperlyConfigured: Error loading psycopg2 module: No module named _psycopg

You're welcome!

You can also take a look to another python web-server.
Especially if you want to have for example two sites with different 
version of python on the same server.

When I wrote my first django-app on py3, I faced the same problem.

Hi Timothy,

Note that your mod_wsgi module compiled for using python2.7. So
what you need now is install(compile) mod_wsgi for python3
instead of the same module compiled for python2.7.
On Debian you can do it by this command:
$ sudo apt-get install libapache2-mod-wsgi-py3


Thanks,  After some poking around, I did find that this was the 
problem.  Now, recompiling it on CentOS (with Python 3 as an alternate 
install) was quite another trick.  :-)


Thanks.

This question is also on Stackoverflow http://goo.gl/LinMue  but I 
thought somene here may have an idea.



I have a Django 1.5, Python 2.7 site running under Apache with 
mod_wsgi on a CentOS 6.4 server.


I have rebuilt this site using Django 1.6 and Python 3.3. Deploying it 
to the same server and changing the paths in httpd.conf I get the 
subject error. This new install works as expected using ./manage.py 
runserver.


Here are the two WSGI definitions from httpd.conf:

|WSGIScriptAlias/  /home/ccdgen/CCDGEN2/apache/wsgi.py
WSGIPythonPath/home/ccdgen/CCDGEN2/ccdgen/ccdgen:/home/ccdgen/CCDGEN2/ccdgen:/home/ccdgen/CCDGEN2/lib/python3.3/site-packages


  Order  allow,deny
  Allowfrom  all



#WSGIScriptAlias/ccdgen/home/ccdgen/CCDGEN/apache/wsgi.py
#WSGIPythonPath/home/ccdgen/CCDGEN/mlhim/ccdgen:/home/ccdgen/CCDGEN/mlhim:/home/ccdgen/CCDGEN/lib/python2.7/site-packages
#
#
#  Order  allow,deny
#  Allowfrom  all
#
#|

The wsgi.py file is the same on both installations:

|import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE",  "mlhim.settings")
from  django.core.wsgi import get_wsgi_application
application=  get_wsgi_application()|

Thanks in advance for any ideas.

Cheers,
Tim

Re: Filtering by month doesn't work

[Начаров Михаил]

Hi Tranta.
In my projects this functionality works fine. 
What version of django did you used? 
Do you sure that field end in Event table contains November dates?

Also, you can use *today.month* instead of  *int(today.strftime('%m')*) and* 
today.year *instead of  *int(today.strftime('%Y')).*
And in django docs says that it necessary to validate your form before use 
it:

*if event_form.is_valid():*
*event = event_form.save()*

Min requirements for running django?

[Начаров Михаил]

Hi, Etienne,

I'm using django in my apps about half of a year and deploy some apps
already. It's hard to say how much memory you need, because it's really
depends of what work you want to do on server-side. If it's only creating a
dynamic-pages and filling the database with data coming from users, I think
100MB RAM will be enough. But remember to set DEBUG=False in your
settings.py in the deployed app otherwise, the amount of required memory
can be much larger.
And take a look on deployment section in django
documentation<https://docs.djangoproject.com/en/1.4/#the-development-process>.
It really helps.

With love from Russia,
Mikhail
