Django Custom Template Tags In Google App Engine

Question

I am trying to include the following Tag In Google App Engine Web Application:

http://www.djangosnippets.org/snippets/1357/

Is there any configuration of this file to make it work with Google App Engine?

Cause I followed the Django Template tutorials: http://docs.djangoproject.com/en/dev/howto/custom-template-tags/

and have this structure:

templatetags/
    __init__.py
    range_template.py

in the Template file, I have {%load range_template%}

But I am getting the error:

TemplateSyntaxError: 'range_template' is not a valid tag library: Could not load template library from django.templatetags.range_template, No module named range_template

The other thing that might be a problem why this ain't working is, the INSTALL_APPS settings.py file. Not sure how to configure it.

I have a settings.py file in the root of my application and included this:

INSTALLED_APPS = ('templatetags')

Any advice would be greatly appreciated.

Answer 1

Please make sure to restart the development server after following the above step

Answer 2

try doing the following:

$ python ./manage.py startapp foo

Add foo to installed apps:

INSTALLED_APPS += ('foo',)

And move your templatetags directory into your foo app. Something like:

./djangoproject
    __init__.py
    settings.py
    urls.py
    etc..
    foo/
        __init__.py
        templatetags/
            __init__.py
            range_template.py

Django convention is that template tag code resides in apps, in directories named templatetags (see docs). I assume the same would be true for GAE.

In case someone searches for this, I wrote a small article in 2008 about this: http://daily.profeth.de/2008/04/using-custom-django-template-helpers.html
