The grandparent, parent, child relationships maybe too complex for
smartgrid, or maybe a bug in smartgrid? Try to use the IF statement to
differentiate the relationships:
if 'DictionaryType.languageID' in request.args:
db.Word.dictionaryTypeID.represent = lambda id:
db.DictionaryType(id).dictionaryName
else:
db.Word.dictionaryTypeID.represent = lambda s,r: s.dictionaryName
