No, that won't work -- "query" is a Query object, so "True if query else 
False" will simply always be True (the query itself is not somehow executed 
for each row).

Instead, "editable" can be a callable that takes a row and returns True or 
False. So, if the record has, for example, a created_by field, you could do:

SQLFORM.grid(..., editable=lambda row: row.created_by == auth.user_id)
