I have a hard time with these grid/smartgrid callbacks. Now regarding the 'create' option:
If I put grid = SQLFORM.smartgrid(db.mytable, .... ,create=False), then correctly, the '+Add' button doesn't appear on the web application. But if I put a lambda callback there: grid = SQLFORM.smartgrid(db.mytable, .... ,create=lambda row:False) the 'Add' button appears! --
