Re: SqlAlchemy Adapter

Hi Dave,

I had to make slight changes to your version of SQLAlchemy adapter to  
return the correct results for my project. The patch is:

The reason for using object's mapper to iterate properties instead of  
fetching object's __dict__ is because SQLAlchemy initially creates  
_CompileOnAttr except if you manually call mapper's compile method.

Expecting your comments,

Cheers,

Nikos.
