I know this isn't the SQLAlchemy list, but I've been designing my resource tree using SQLAlchemy and traversal for my up coming project. I was thinking about starting a discussion and possibly getting some help on a problem I'm having.
I have the Foo resource, which is an object mapped to the foo database table. Foo has has Bars. Bar is an object mapped to the bar database table. Bars belong to Foo as a one to many relationship. I am using SQLAlchemy's relationship() function to map bars to foo. When I call foo.bars, I need all the Bar objects in the collection to have the Foo instance as it's __parent__. Has anyone solved this? I see that relationship() has the collection_class attribute. I already tried extending list type and overloading the append and extend methods to set __parent__ and then call super(). It didn't seem to work as I don't have __parent__ on any of the child Bar instances. Any help would be appreciated. I would also encourage a discussion on how to approach this cleanly.
