cache.set(key, timeout=0)

[Thomas Güttler]

I want the cache timeout to be configurable:

- N --> number of seconds
- None --> cache for every
- 0 --> do not cache at all.

I am not sure if timeout=0 really does what I want.

I could not find it explicitly in the docs: https://docs.djangoproject.com/en/1.7/topics/cache/#basic-usage

I don't want to put a lot of "if default_cache_timeout==0: ...." into my code.

It would be nice if django would support this. This would make my code simpler.

Does cache.set(key, timeout=0) do no caching at all?

If yes, shouldn't this be stated in the docs explicitly?

Regards,
Thomas Güttler

Hi Thomas,

You are correct - if you set timeout=0, the cached value immediately expire (effectively "don't cache"). 

This appears to be an oversight of the documentation; the section you reference includes a discussion of the None value, but not the 0 value - a clarification would definitely be worthwhile. 

If you open this as a ticket, we can make sure your suggestion isn't forgotten. It would also be a very easy contribution to make - the patch would be a very simple one

Yours
