is this a pydal issue?

What does this error mean? (code seemed to work, before pydal...)

Your are comparing Rows with None.

The question is why?

Normally, you should compare Rows with Rows. 

In pydal we can add a check to raise an error if the second argument isn't an instance of Rows.

You should be able to just write:

if not (op_rec and op_rec2 and op_rec3 and op_rec4)

parameter "op_rec" is set to a session parameter that under normal operating conditions is a "Rows" object

if a person goes to the page directly (not the "normal" method) then the "op_rec" parameter would be None and in that case, the code simply redirects the person to a function that sets it to the "Rows" object

thanks for your response!

[Paolo Valleri]

ok, I get it. 

I'll post an update later today to fix the backward compatibility

this works! thanks...

[Auden RovelleQuartz]

ok thanks

i found workaround (via Marin), but handling None condition would preserve backwards compatibility and make more robust

thanks again for everything!
