Custom Django filters in Google App Engine
You want to create your own custom Django filters in App Engine without running a whole Django stack? Here's how in a few lines of code.
First create a specific python file to hold your custom filters at the root of your application. In my case I use customfilters.py like this:
import re from google.appengine.ext import webapp register = webapp.template.create_template_register() def escapeimg(body): return re.sub(r'<img (.*)/>', '[IMG]', body) register.filter(escapeimg)
Then in your main application source file, call the following line outside of the main() definition, for example just after your modules loading:
"""Load custom Django template filters""" webapp.template.register_template_library('customfilters')
You should then be able to use the new filters you registered in customfilters.py straight away in any of your Django templates without any % load foobar % call
