[web2py] Is there a way to use query in autocomplete with SQLFORM.factory?

[Dragan Matic]

I would like autocomplete to show just a subset of data, not all rows in 
table. Is it possible to use query in autocomplete like this? 

  
query = db.recipe.user_id==auth.user_id
    
form=SQLFORM.factory(Field('title', 'string', required=True, requires=
IS_NOT_EMPTY()),
        Field('type', 'string', 
             widget=SQLFORM.widgets.autocomplete(request, db(query).select(
db.recipe.type), limitby=(0, 10), min_length=2)), 
        Field('body', 'text'))


This currently throws the following exception:
<type 'exceptions.AttributeError'> 'Rows' object has no attribute 
'tablename'
