I was misunderstood (my mistake - it's getting late here in Greece). I didn't want to say about the list but about taking an argument. > after_update should be a list of functions, that take one argument, the row.
Now that I am thinking about it, I think that these functions must have access to table data. For example, creating permalinks after a title field has been updated, means that a create_permalink function must have access to the db.table.title and to the db.table.permalink. The thing is that I am making changes inside the update function (in sql.py) - after the self._db._execute(query) but I don't believe I have access to table's data. Am I doing something wrong here? Should I patch somewhere else (first time reading the sql.py)?
