Registering templates in App Engine

Although in App Engine we are using django templates language the loading of custom template tags is bit different.

In django you can use {% load my_custom_tags %} in your templates to load the custom template tags. This does not worked for me in the App Engine.

Here is how I made it work. In you handler file (which is runaround/runaround.py for us in this example) I have a code snippet

from google.appengine.ext.webapp import template

template.register_template_library('runaround.templatetags.runaround_tags')

runaround/templatetags/runaround_tags.py is the name of file/module which contains the template tags. Its contents were described in this post.
