Invalidation happens only at template compile time

[akaihola]

The invalidate_template_cache() function is called inside the reset_cache() function, which in turn is registered as a template tag.

If I've understood correctly, Django executes the reset_cache() function only at template compile time. Because of this, invalidate_template_cache() is also called at compile time but never at render time.

Anything that needs to be done at render time should be in the .render() method of a template.Node subclass, and an instance of that class should be returned by the reset_cache() function.

I can't see how the tag could work as intended the way it's now implemented.

I'll look into this -- I wrote this then got busy on other things before I could implement it. I believe that because this is only a way for the template to tell the cache system to do something, with nothing printed in the template, that we can therefore safely treat compile and render as identical.
