Thanks. But I worked around the solution by adding a empty app to the
INSTALLED_APPS that points to an empty .py file. Seems to work, but I get some
random errors from my custom filers file saying that they don't exists.
When searching around I found that it's a bit confusing for many developers to
get django 1.1 running. Is there any guides?
My main reason for upgrading to 1.1 is to use for-loop with {% for name, type
in obj %}.
What is the mere basic you need to get 1.1 running (hopefully with out any
random errors). As of now I only have a settings.py:
import os.path
PROJECT_DIR = os.path.dirname(__file__) # this is not Django setting.
TEMPLATE_DIRS = (
os.path.join(PROJECT_DIR, "templates"),
# here you can add another templates directory if you wish.
)
And in top of all my .py:
import os, sys, cgi, re, logging
# Google App Engine imports.
from google.appengine.ext.webapp import util
# Remove the standard version of Django.
for k in [k for k in sys.modules if k.startswith('django')]:
del sys.modules[k]
# Force sys.path to have our own directory first, in case we want to import
# from it.
sys.path.insert(0, os.path.abspath(os.path.dirname(__file__)))
# Must set this env var *before* importing any part of Django
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from google.appengine.dist import use_library
use_library('django', '1.1')
from django.conf import settings
settings.configure(INSTALLED_APPS=('empty',))
from google.appengine.ext.webapp import template
....
What do I need to replace google's template import? Is there any other files I
need?
The solution above works (in some sense) but it seems a bit like it could break
any moment. Especially pointing out a empty app and del modules from
sys.modules.
Is there something google does to set the version to 0.96? And could these two
settings interfere with each other?
