*Hello everybody,*
*
*
*I would like to ask you how to solve an issue that is actually driving me
crazy. I have found several threads and workarounds of people who seem to
have faced a similar problem, but I havent actually found a valid solution
to my problem. Here it is:*
*
*
*1. I have several VirtualHosts defined in my Apache configuration file.
Each of these VirtualHosts try to access a GUI which has been designed
using Python and mod_wsgi. In these Apache configuration files, I have
defined an Environment Variable which I then use in the wsgi script*
SetEnv MY_VAR my_var_name
...
WSGIScriptAlias /gui "/guipath/django.wsgi"
*2. Googling a bit, I found a guy answering how to actually use Environment
Variables in the templates. In this sense, it was necessary to set them in
the WSGI script file. Below is my WSGI file:*
import os
import sys
path = os.path.dirname(os.path.abspath(__file__)) + '/..'
path2 = os.path.dirname(os.path.abspath(__file__))
if path not in sys.path:
sys.path.append(path)
if path2 not in sys.path:
sys.path.append(path2)
os.environ['DJANGO_SETTINGS_MODULE'] = 'gui.settings'
import django.core.handlers.wsgi
_application = django.core.handlers.wsgi.WSGIHandler()
def application(environ, start_response):
os.environ['VAR_NAME'] = environ['MY_VAR']
return _application(environ, start_response)
*3. Then, in settings.py, I am actually loading this variable in order to
be used from the views.py file*
*
*
*
*
VARIABLE = os.environ['VAR_NAME']
*
*
*
*
*4. Finally, I import the settings file in the views file, and I then load
the value of VARIABLE in each of the views.*
*
*
*
*
*All the process seems to work OK, except for the following problem. *
*
*
*- In my case, each VirtualHost has been configured to have a different IP,
and a different MY_VAR value, and all these IPs can actually access to the
GUI. The problem arises when I try to switch from one IP to another. Let us
assume the case of two different virtual hosts. Let us call them VH1 and
VH2.*
*- If I type the IP corresponding to the GUI of the first virtual host, I
receive for the first time*
*
*
*
*
"WELCOME TO THE VH1 GUI"
*
*
*
*
*- Then, I switch to the IP corresponding to the second virtual host. The
result I receive is then*
*
*
*
*
"WELCOME TO THE VH1 GUI" *
*
*- Now, if I restart Apache, and I reload this second IP, y receive:*
*
*
*
*
"WELCOME TO THE VH2 GUI" *
*
*- I have checked whether the environment variable assignation was working
or not, by printing the value in the WSGI script, and the value was
changing each time I switched from one virtual host to the other. So the
problems seems to be that settings.py is loaded just once at the beginning,
and the variables are not refreshed any more.*
*
*
*Could you please tell me a way to solve this problem?? I would be
extremely grateful!!!!*
*
*
*Thank you very very much in advance.*
*
*
*With kind regards,*
*Alvaro*
