[Zope-dev] can't register adapters for classes with metaclasses
Hi All,
This is particularly problematic when using the common case of
SQLAlchemy declaratively mapped model classes.
The attached unit test when run will fail with:
Error in test test_provideAdapter (test_sa.TestAdapter)
Traceback (most recent call last):
File /usr/local/lib/python2.6/unittest.py, line 279, in run
testMethod()
File test_sa.py, line 25, in test_provideAdapter
provideAdapter(MyAdapter,Model)
File
zope.component-3.10.0-py2.6.egg/zope/component/globalregistry.py, line
72, in provideAdapter
base.registerAdapter(factory, adapts, provides, name, event=False)
File zope.component-3.10.0-py2.6.egg/zope/component/registry.py,
line 182, in registerAdapter
required = _getAdapterRequired(factory, required)
File zope.component-3.10.0-py2.6.egg/zope/component/registry.py,
line 414, in _getAdapterRequired
for r in required:
TypeError: 'DeclarativeMeta' object is not iterable
Why is that and how should I register an adapter against such a class?
cheers,
Chris

You are allowed to catch them, but not raise them. This is so you can have code that runs on old Pythons with old libraries still. But in any case I think we safely can move them to ordinary exceptions. ___ Zope-Dev maillist - Zope-Dev@zope.org https://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope )

I'll review, merge and release. Should be sometime this week, cannot promise a day. Branch reviewed, merged and released in Acquisition 2.13.6. Could you remove the merged branch once you updated your buildout config? Done. Thanks for releasing! This change introduces a regression when calling unicode on wrapped objects that implement __str__ but not __unicode__. Essentially it is now doing the equivalent of str(aq_base(obj)) ... __str__ used to get a wrapped object as 'self', but now it is unwrapped. Here's a failing test that can be added to Acquisition's TestUnicode test case to demonstrate the issue: def test_str_fallback_is_still_wrapped(self): class A(Acquisition.Implicit): def __str__(self): return str(len(Acquisition.aq_chain(self))) wrapped = A().__of__(A()) self.assertEqual(u'2', unicode(wrapped)) This is currently causing some regressions in Plone tests. I'll have a look at it.
