Resetting cache for Django cached template loader

Question

Django 1.2 introduced a new template loader, that stores data in cache ( django.template.loaders.cached.Loader ).

Unfortunatly, i failed to find any info on how the cache is invalidated and when and how it is reset.

I want to use this on my server, but i'm not sure, that it would reset on django restart (that would be enough for me).

Answer 1

from django.template.loader import template_source_loaders

def reset_template_cache():
    if not template_source_loaders:
        return

    for loader in template_source_loaders:
        loader.reset()

There you go :)

Answer 2

The existing solutions written here broke around Django 1.9, due to the template loader system having been refactored. If you try to use the code that imports template_source_loaders and that import fails, try this:

from django.template.loader import engines

for engine in engines.all():
    engine.engine.template_loaders[0].reset()

This code assumes that your TEMPLATES setting is using the default 'loaders' option, or using only a single django.template.loaders.cached.Loader.
