Hi! First of all sorry if it is not correct list for this question but there is no Zope3-DB... maybe Zope3-users or Zope3-dev?
I've just tried to use Zope3.3.0 with cx_Oracle adapter and to check whether connection works I've used typical for Oracle statement: select 1 from dual I've received error: TypeError: __slots__ must be identifiers The problem is (I think) with class Row or RowClassFactory defined in zope/rdb/__init__.py. There is current implementation of RowClassFactory: def RowClassFactory(columns): """Creates a Row object""" klass_namespace = {} klass_namespace['__Security_checker__'] = InstanceOnlyDescriptor( NamesChecker(columns)) klass_namespace['__slots__'] = tuple(columns) return type('GeneratedRowClass', (Row,), klass_namespace) in my case: klass_namespace is {'__slots__':('1',)} and '1' causes error. select 1 as abc from dual executes correctly. I've implemented temporary solution that simply changes the names of numeric attributes (like '1') to prefixed ones (like '_1') It works but I'm not sure whether it is proper solution for something other than tests, but in general who may use this kind of dynamically created labels for something useful...? Is this issue a bug or feature or something else. I'm not able to recognise them myself (especially after submitting request.locale issue on z3-five list :)). I would like to know your's opinions before submiting a bug and/or trying to create a patch. -- Maciej Wisniowski _______________________________________________ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
