[ZPT] using tal:attributes with <option> select and ZSQL.

[Luis Lavena]

Sorry reply to tis too late, but te trobule was due a comparision of string
and integers.

Wasn't checking the result from the PyScript and that was my mistake.

Added a int comparision solved the problem.

Thanks for your reply.

Regards,

Luis Lavena

on or about, Thursday, May 30, 2002, we have reason to believe that
Luis Lavena wrote something along the lines of :

don't work in which way ?
Do you get an error , or just no selected options.

PyScript

- if i assume you just get no selected options:

perhaps this could work ?
tal:attributes="selected python:item.idgrillasenales ==
params['idgrillasenales']"

if i run into unexpected behaviour when doing comparizations like this
, i try to print both variables being compared in the value of the
select , so that it is simple to see the problem:

tal:attributes:value="string:${item/idgrillasenales}/${params/idgrillasenale
s}"


also make sure both items being compared are of the same type.. Much
frustration can be had by trying to compare integers and strings:

tal:attributes="selected python:int(item.idgrillasenales) ==
int(params['idgrillasenales'])"
