Currently if you ask a registry to singly-adapt an object to an interface, and the object you're trying to adapt implements that interface, here's what happens:
from zope.component.registry import Components c = Components() from zope.interface import Interface, implements class IFoo(Interface): pass ... class Foo(object): ... implements(IFoo) ... foo = Foo() c.queryAdapter(IFoo, foo) <None>
Looking back in history: https://mail.zope.org/pipermail/zope-dev/2008-August/032902.html I guess one or other of us has the parameter order wrong, probably me. Much thread ensued: https://mail.zope.org/pipermail/zope-dev/2008-August/thread.html#32902 https://mail.zope.org/pipermail/zope-dev/2008-September/thread.html#33174 Some justification for keeping the status quo from Fred: https://mail.zope.org/pipermail/zope-dev/2008-September/033172.html I stand by my resultant request here: https://mail.zope.org/pipermail/zope-dev/2008-September/033170.html Maybe less people care about ZCA now and so we might actually get sensible changes made. Maybe forking would be easier... cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
