[Zope] Accessing individual items within a list

[McDonnell, Larry]

Hi,

The serail number has 3 records (cell_number) I wish to update each record
with the proper pbtemp information.

My input is still as follows:

<dtml-in expr="_.range(3)">
  <input type="text" name="pbtemp[sequence-index]" size="6">
</dtml-in>

Alexis Roda sent me directly some suggestions that I tried but it produced
an error.

<dtml-call "REQUEST.set('serial_number', 'mem0314701')">
<dtml-call "REQUEST.set('cell_number', 0)">

<dtml-in expr="_.range(3)" prefix="p">
<dtml-call "REQUEST.set('cell_stack_number', cell_number+1)">
<dtml-call "REQUEST.set('cell_number', cell_number+1)">

    <dtml-call expr="testing(parameter=pbtemp[p_index])">
            
</dtml-in>

But I see this error:

Error Type: NameError
Error Value: global name 'pbtemp' is not defined

The zsql is as follows:

update atp_fields 

set pbtemp=<dtml-if pbtemp><dtml-if "pbtemp==''">NULL<dtml-else>
 <dtml-sqlvar pbtemp type=float></dtml-if><dtml-else>NULL</dtml-if>

where serial_number=<dtml-sqlvar serial_number type="string"> and
      cell_stack_number=<dtml-sqlvar cell_stack_number type="int">

The zsql works when I test it. At first I was just trying to display the
values of pbtemp[x], but Alexis gave me zsql call statement so I that is
where I am at now.

First you have to decide what HTML you want to produce.  Then you can
work out how to generate it.

I take it that you want something like this -

<tr><td><input name='name1'></td></tr>
<tr><td><input name='name2'></td></tr>
<tr><td><input name='name2'></td></tr>

This is easy - you just put it into the loop you already have -

<dtml-in expr="_.range(3)">
     <tr><td><input type="text" name="pbtemp[sequence-index]"
size="6"></td></tr>
</dtml-in>

There is no sense trying tp generate anything if you do not know - at
least have a good idea of - the results you want.  Always work out the
html first.

If this is not what you had in mind, then please communciate the output
you want.

Cheers,

Tom P
