Re: Boolean test on queryset

Jirka, That doesn't solve the problem. That will still do a very expensive count() operation on the queryset. In fact, examples.count() is what happens when you do bool(examples) anyway. Thanks, Adam On Mon, Nov 28, 2011 at 8:11 PM, Jirka Vejrazka wrote: > Hi Adam,

Serve a tracking pixel via Django

We have one static file that needs to be served after business logic has run (i.e. log a view on a specific url based on a unique code). We used to use serve() in production. This has always been frowned upon but with Django 1.3, the errors are worse. Can one return an image in any other

Best Practices - Model Changes on Production servers

Re: A Very Puzzling MySQL Issue Performance...

Also, you could limit the result set to the number of records you actually need. 5k seems like an absurdly large result set. One final thing would be if you could pre-cull the Person data by narrowing it down to active users or something. The active_user field (if there is one), could quickly
