Django template fragment caching - is it possible to prerender?
I am looking into Django caching mechanism, namely template fragment caching.
I am planning to cache list of books for every institute, because it takes too long to fetch it and render on every request. I plan to use it like this:
% load cache %
% cache 600 sidebar student.institute %
<List of books for the institute>
% endcache %
If I understand correctly, it will work like this:
For the first request from a student from the institute the list of books will be fetched and rendered, but for all subsequent requests it will be just taken from cache, till the cache invalidates.
So the first request after invalidation is always slow.
Is it possible to automatically pre-fetch and pre-render this template fragment for all possible institutes, so that even the first request would just hit the cache?

For now I've come up with two ideas: 1) Use Celery or other async task scheduler to add the cache manually using low-level cache API 2) Use Celery or other async task scheduler to just imitate requests I need to cache Both of the solutions are not optimal. I still hope to find some better way to do it.
