db.document.page_id==page.id is not a boolean -- it is a DAL Query object. db.document.page_id is a DAL Field object, which inherits from the DAL Expression class. The Expression class overloads a number of Python operators (such as ==, <, >, etc.), so when those operators are applied to a Field object, they result in a Query object rather than a boolean. The first argument of SQLFORM.grid can be either a query or a db table. > and a > list (args = [page.id]) to grid.
