Hi All, I'm trying to get working the slice in the subject that are in web2pyslices.com[1] but it's something wrong with my code that I still can't see and is breaking the view. The widget works well for me if I use the same code as show in web2pyslice (aka 'copy&paste'), but does not work with my model. I put the widget's code in 'db.py' and my tables are on 'db_wizard.py[2]'. The instance of the widget it's also in 'db_wizard.py'.
It says 'Key Error' but I can't justify why because I don't know yet how to see this problem. May worth to say that It also works if I remove 'db.t_categoria' from line 110 in [2], as: (...) cascade = CascadingSelect(db.t_subcategoria,db.t_articulo) (...) LINKS: [1] http://web2pyslices.com/main/slices/take_slice/85 [2] http://ompldr.org/vNzhnMg The model has no problem without the widget. What am I doing wrong? Very thanks in advance for your help and time on this.
