Hi all,
There is a bit of cruft in LazyObject that I'd like to fix -
'get_all_members'. This seems to be left over from before it got
separated from LazySettings. The method is *only* needed to support
introspection, which is usually only used from the interactive prompt.
There is a much better way of doing it - implement the __members__
property and the __dir__() method. This is the standard and future
compatible way.
I'll need to fix the few instances of where LazyObject is subclassed
in Django itself.
If anyone else has subclassed LazyObject, from now on the
'get_all_members' method of wrapped objects will be ignored. In most
cases, this will have no effect, because the default __dir__() will do
the right thing.
In exceptional cases (where the wrapped object implements
__getattr__()), introspection won't return all the attributes that it
should.
Upgrading is easy - if your wrapped object does not implement
__getattr__(), just remove 'get_all_members()'. If it does, replace
'get_all_members' with '__dir__', and if using Python < 2.6, add:
__members__ = property(lambda self: self.__dir__())
Any objections to this? I can only imagine that it will affect
interactive usage at the Python prompt in a few obscure cases, if
anything. But I could have missed something.
