Grid - After update

[Julio César Albornoz]

Hi everyone

I want to know if a column has changed, then I would like to encrypt it.
I was doing tests with after_update:

db.tconnection._after_update.append(lambda id, row: fencrypt_pwd('update',id,row))

But this event is triggered several times, then I got wrong values, because it is encrypted a lot a times.

Does anybody have any suggestions for this issue?

Thanks in advance.

Many of those magic methods like like _after_update were really meant for py4web and are poorly documented anyway.

I would recommend:

form = Form(..., dbio=False)

if form.aaccepted:

    db.table.insert(x = form.vars.get("x"), y = encrypt(form.vars.get("y"))

Umm, was that "meant for web2py"?  Venerable, and much loved, but py4web has a lot of "lessons learned" in its design.

 

and are poorly documented anyway.

form = Form(..., dbio=False)

This looks way too straight-forward.

It always amuses me when GG warns you of "email addresses in post", when those address are already in the message you are replying to.
