I have two functions in a signals.py module that I would like called
whenever instances of a number of models are saved or deleted.
Everything works as intended when I add all of this to each models.py
module:
from django.dispatch import dispatcher
from django.db.models import signals
from project.feed_summary.signals import create_feed_summary,
delete_feed_summary
class Foo(models.Model):
...
dispatcher.connect(create_feed_summary, sender=Foo,
signal=signals.post_save)
dispatcher.connect(delete_feed_summary, sender=Foo,
signal=signals.pre_delete)
However, I would really love have a tuple in settings.py something
like:
FEED_SUMMARY_SETTINGS = ('model_import_path',)
And just tack models onto that as necessary, with something like this
somewhere in the feed_summary app so that it is self-contained:
for m in FEED_SUMMARY_SETTINGS:
dispatcher.connect(create_feed_summary, sender=m,
signal=signals.post_save)
dispatcher.connect(delete_feed_summary, sender=m,
signal=signals.pre_delete)
Is this possible? Advisable? If so, where is the best place to drop
that code so the dispatchers don't just get garbage collected?
Thanks,
Jonathan
