Or "Just before request handler or manage.py command handling" takes place. "Ready" would mean "When django is imported, settings are ready, model classes are ready". > As it is, you have a signal which fires when we start processing an > HTTP request, and that's what most people should look to since Django > is, fundamentally, about cycles of HTTP request/HTTP response and so > that's the most useful mindset to have. Sure, but if you want to run a code that affects all requests (i.e. "Replace the SMTP Connection class for all requests") you can't be doing that *on every request*, the place to do so would be "just before starting serving requests". > Failing that, there are plenty of well-established Python idioms for > "run this code once and only once the first time I'm imported", which > covers the remainder of the use cases (or really stubborn people who > want to act like Django is a desktop application instead of a web > framework). In the case of the ticket I mentioned it's not that easy, as you won't import anything, you have a setting "DISABLE_EMAIL" which has to do what the testsuite does now: Replace SMTP Connection class. So you need to check this setting *after settings have been loaded*. The only signal you can hook "after settings are loaded" are all fired more than once (class_prepared, request_started, etc). There's no signal that gets fired *once*. So, if you need to hook something that need to run *once* after django loads (at any level) you need to either monkey-patch or patch Django itself. I would say to put a signal on every stage of the load process but one just after settings are ready and one just before starting to serve requests or handling manage.py commands would be a nice one. -- http://www.marcfargas.com - will be finished someday. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django developers" group.
