Ok, I applied that change to the version I'm using (0.3.8). That
fixed it.
But I think I stumbled on another bug/inconcistancy.
If I tried to str/repr obj.attr it failed.
I looked around the code and this fix seemed to work, but I'm not sure
if it fits in with how the class is intended to

Does that make sense? Or is the problem deeper in the code? It
seems to go along with what you
Now I'm having trouble with updating values in AttributeDict:
so
obj.attrs['key'] = 'somevalue' (works)
obj.attrs['key'] = 'newvalue'(second one doesn't work)
I get this error:
File /usr/local/lib/python2.4/site-packages/SQLAlchemy-0.3.8-
py2.4.egg/sqlalchemy/orm/mapper.py, line 679,

the legal way is the association_proxy and family.
here another shorter ... a hack:
i did have similar need - obj.somerelation.append( left=.., right=..),
so i did monkeypatch the InstrumentedList's append to use the item
returned from collection's append -
def append( self, *args,
Using the association_proxy extension in combination with your
dictionary collection class is an easy way to get this kind of
simplified access. Assuming your Attribute's value is in a
property called 'value', you can set up simple dict access like so:
class Obj(object):
attrs =

When I try the above I get this error at flush time:
InvalidRequestError: Class 'str' entity name 'None' has no mapper
associated with it
Here is my dictionary collection_class:
class AttributeDictNEW(dict):
My Attribute Dict
def append(self, item):
The association proxy will take care of Attribute construction for
you, so you can get away with just:
class AttributeDictNEW(dict):
def append(self, item):
self[item.key] = item
def __iter__(self):
return self.itervalues()
So now I if I try to get something
