I found kind of what you were looking for on the sqlobject mailing list after trying some other things I had thought of. I don't know how to get the tables names but this will help after that. It should make all your table classes in a list. So that tableClasses[0] will be an SQLObject class(not an instance): def getTableNames(): #not quite sure what to put here but I'll just assume return ['table1', 'table2', 'table3'] def getTableClasses(tableNames): tableClasses = [] for tableName in tableNames: tableClasses.append(makeTable(tableName)) return tableClasses def makeTable(name): """ Copied from here http://article.gmane.org/gmane.comp.python.sqlobject/7719 """ class Test(SQLObject): class sqlmeta: table = name def __classinit__(cls, new_attrs): cls.__name__ = name SQLObject.__classinit__(cls, new_attrs) return Test Do you know the table names you need to get classes for at run time ? -Ian On 1/26/07, Lee Connell <[EMAIL PROTECTED]> wrote: > Not a problem, I didn't take it as criticism.
