python - Cannot get environment variables in Django settings file -

i'm trying read environment variables in django settings, have defined in /home/user/.bashrc (and latter in /etc/bash.bashrc ) , keyerror exception. know environment variables set, because can print them in terminal (echo $var_name). should trivial.

this code i'm using.

from django.core.exceptions import improperlyconfigured  msg = "set %s environment variable"   def get_env_variable(var_name):     try:         return os.environ[var_name]     except keyerror:         error_msg = msg % var_name         raise improperlyconfigured(error_msg)  os_db_user = get_env_variable('my_user') os_db_pass = get_env_variable('my_pass') os_db_db = get_env_variable('my_db') os_game_logs = get_env_variable('dir_logs') 

i can't find what's missing. suggestions out there?

thanks
