IndexError: list index out of range

this is my django code :

#from django.core.management import setup_environ
#from sphinx_test import settings

#setup_environ(settings)


from django.db import models
from djangosphinx.models import SphinxSearch,SphinxQuerySet




class File(models.Model):
    name = models.CharField(max_length=200)
    tags = models.CharField(max_length=200) 

    objects = models.Manager()
    search  = SphinxQuerySet(index="test1")


import datetime



class Group(models.Model):
    name = models.CharField(max_length=32)

class Document(models.Model):
    group       = models.ForeignKey(Group)
    date_added  = models.DateTimeField(default=datetime.datetime.now)
    title       = models.CharField(max_length=32)
    content     = models.TextField()

    search      = SphinxQuerySet(File,index="test1")

    class Meta:
        db_table = 'documents'

and

You need to set Meta.app_label to something usable.

That's odd, that part of the code is just supposed to determine your app name. See the section here starting line 45. What's your app name for this?

You may be able to avoid the error by setting app_label to the name of your app in the Meta section of your model.
