[ZPT] tal path thingies

[Tom Deprez]

Hi,

I'm trying to insert data from a database inside Formulator and I'm almost
there (probably not the best way, but hey I'm learning :-)), but I'm having
problems. Here is my code. Please remove or improve it if you are able to!

<span tal:define="item container/sql_getEquipmentById">
            <form action="." method="POST">
            <table border="0">
              <tr tal:repeat="field here/form/get_fields">
                <td><strong
tal:content="python:field.get_value('title')">Title</strong>
                    <span
tal:condition="python:field.is_required()">*</span></td>
                <td tal:define="fname
python:field.get_value('alternate_name');aValue
python:path('item[0]/%s'%fname);">
                    <input type="text" name="foo"
                           tal:replace="structure
python:field.render(aValue)" /></td>
                <td><i
tal:content="python:field.get_value('description')">Description</i></td>
              </tr>
              <tr><td colspan="2"><input type="submit" value=" OK
"></td></tr>
            </table>
            </form>
</span>

So, it basically calls a zsqlmethod which will return one record, the
important part is:

                <td tal:define="fname
python:field.get_value('alternate_name');aValue
python:path('item[0]/%s'%fname);">

I can show the value through <td tal:content="python:item[0].IPADDRESS">
but I want that 'IPADDRESS' is variable, depending on the Formulator field
I'm writing. I can get the 'IPADDRESS' part through
'python:field.get_value('alternate_name');'; but how do I then create the
path to item[0].IPADDRESS ?

And is there another way than just using item[0] ?

Thanks, Tom.
