Question

I’m running a django app through fcgi on my school’s shared hosting system. Everything works initially (standard start page shows when I view the directory with index.fcgi) but when I add a module and try to import, I get the following error. The same code works when I run on my local machine.

Two questions. One, it seems like the same error as this but I can’t figure out what to add to my pythonpath. Here’s the contents of my index.fcgi. I tried executing

sys.path.insert(0, "/keone/Scripts/django/resume/students")

but that didn’t help.

#!/usr/bin/env python
import sys, os, time, threading, django.utils.autoreload
sys.path.insert(0, "/keone/Scripts/django")
os.chdir("/keone/Scripts/django/resume")
os.environ['DJANGO_SETTINGS_MODULE'] = "resume.settings"

def reloader_thread():
  while True:
    if django.utils.autoreload.code_changed():
      os._exit(3)
    time.sleep(1)
t = threading.Thread(target=reloader_thread)
t.daemon = True
t.start()

from django.core.servers.fastcgi import runfastcgi
runfastcgi(method="threaded", daemonize="false")

Two, how do I change the fcgi file to close standard output and standard error and reopen them to a different file? I had to get a sysadmin to get a snippet out of the master log, and I can’t count on this consistently.

Thanks for your help!

Answer 1

1. Does sys.path.insert(0, "/keone/Scripts/django/resume/") work? I assume everything is working fine in a runserver.

2. You can pass in outlog and errlog to runfastcgi. http://code.djangoproject.com/browser/django/trunk/django/core/servers/fastcgi.py?rev=10345#L21
