How to disable Django query cache?

Question

In my Django application, I repeatedly run the same query on my database (e.g. every 10 seconds). I then create an MD5 sum over the queryset I receive and compare that to th

Thank you very much for your answers, your replies made me take a few steps back and rethink.

In order to test caching on a DBMS level, I went away from Django and used a shell script I anyway had handy to periodically query data from a SQLite db, while I added data in a second shell session. The new data showed up in the periodic queries right after I added them, so no query caching here.

This narrowed it down to the Django part. The code involved is not very complex and a little log output and a code review revealed the problem: The query used to obtain the queryset used in turn to create the MD5 sum had an error and was always empty. Therefore, the MD5 sum was always the same. Did indeed look like a cached result - data is changing, but the queryset stays the same. The problem did not show in the application, as a different query was used to obtain data displayed there.

Lesson learned: If you're completely puzzled, take a step back and re-think your assumptions.

Thanks again! :-)
