Hi All, I have a mixin class here that I've factored out of one project as I want to use it in another one:
<https://github.com/Mortar/mortar_mixins/blob/master/mortar_mixins/temporal.py> https://github.com/Mortar/mortar_mixins/blob/master/mortar_mixins/temporal.py The problem is that importing the module seems to result in the following exception being raised: >>> from mortar_mixins.temporal import Temporal Traceback (most recent call last): File "<stdin>", line 1, in <module> File "mortar_mixins/temporal.py", line 81, in <module> listen(Temporal, 'instrument_class', add_constraints, propagate=True) File "/Users/chris/vcs/git/mortar_mixins/lib/python2.7/site-packages/sqlalchemy/event/api.py", line 89, in listen _event_key(target, identifier, fn).listen(*args, **kw) File "/Users/chris/vcs/git/mortar_mixins/lib/python2.7/site-packages/sqlalchemy/event/api.py", line 28, in _event_key (identifier, target)) sqlalchemy.exc.InvalidRequestError: No such event 'instrument_class' for target '<class 'mortar_mixins.temporal.Temporal'>' My guess is something to do with it not being mixed into any classes at that point. Weirdly, it seems to work fine, and all the tests run and pass, although the nose run will spew the above error in addition to running the tests. To reproduce, just follow the instructions here: <https://github.com/Mortar/mortar_mixins/blob/master/README.rst#development> https://github.com/Mortar/mortar_mixins/blob/master/README.rst#development Any ideas what I should do to resolve this? cheers, Chris -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
