Configuring NSPredicateEditor(RowTemplate) for Spotlight metadata queriesI'

I'm trying to configure an NSPredicateEditor (in Interface Builder) to edit the predicate for an NSMetadataQuery. As a first step, I'm trying to configure an NSPredicateEditorRowTemplate to accept key path(s) for the left-side expression, trying a single keyPath (kMDItemTextContent) to get started.I can't figure out how to get all the pieces into IB. I've selected the row template, and set "Left Exprs" to "Key Paths" in the IB Attributes Inspector. But, using Apple's PhotoSearch example as a model, it appears that I should enter a user-readable attribute name (say, "Content...

Want to disable signals in Django testing

So I have various signals and handlers which are sent across apps. However, when I perform tests / go into 'testing mode', I want these handlers to be disabled.Is there a Django-specific way of disabling signals/handlers when in testing mode? I can think of a very simple way (of including the handlers within an if TESTING clause) but I was wondering if there was a better way built into Django?... No, there is not. You can easily make a conditional connection though:import sysif not 'test' in sys.argv: signal.connect(listener, sender=FooModel) [XXX]I found this ques...

And, most likely, you locked them, running the same UPDATE in another transaction. Just Commit/rollback your transactions, you should be fine.
