No, SQLFORM.factory returns a SQLFORM object, which inherits from FORM. Once created, you can add elements via server-side DOM manipulation <http://web2py.com/books/default/chapter/29/05/the-views#Server-side-DOM-and-parsing>, but not by adding a DAL Table or Field object as when calling the .factory() method. Instead, inside a loop or list comprehension, you can build up a list of DAL Tables and or Fields, and then use Python argument unpacking to pass the entire list to SQLFORM.factory. For example: tables = [db[t] for t in ['table1', 'table2', 'table3']] form = SQLFORM.factory(*tables) Anthony -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
