[Zope] Syntax

[Paul Zwarts]

The best bet is to check the DTML Users Guide. Although it is a long hard
stare. Check the Zope book as well for fundamentals.

>>>Is this refering to an earlier item in the sequence?

<dmtl-in list>
  <dtml-if "_['sequence-index']==5">This is the fifth occurance</dtml-if>
</dtml-in>

Yes indeed.

>>>Is it the same as _.sequence-item-5 ?

The above is not possible. Remember that _ has a dual function. It A)
accesses namespace:

_.string.find('stringname, 'findStringText')

_ pushes the results of the method into namespace.



_.int(string)

and so on...

_['some-name'] has NOTHING to do with namespace. It only prevents 'some'
being subtracted by 'name', when you intend some-name to be only one object.


>>>If I have a name clash (two Z SQL Method's return ID), how to I look up
the
stack of namespaces?

Dont use ID as good practice, since ID is the document ID. BUT you can
return REQUEST['id'] which is the REQUEST variable and not necessarily the
Zope object ID. If you have multiple ID used in a nested <dtml-in> the ID
resulted is owned by its superior IN.

Forinstance, I add an 'a' or 'b'to ID to show:

<dtml-in methoda>    <-- You will return an ID here-->
  <dtml-var ID>
  <dtml-in methodb>  <-- You will return an another ID here-->
    <dtml-var ID>
  </dtml-in>
<dtml-in>

Now I a the result

<dtml-in methoda>    <-- You will return an ID here-->
  <dtml-var ID(a)>
  <dtml-in methodb>  <-- You will return an another ID here-->
    <dtml-var ID(b)>
  </dtml-in>
<dtml-in>

AFIAK. Possibly not.


If you want to look up namespace, simply put

<dtml-var REQUEST>
in the bottom of your page and you will see all.....

Is this refering to an earlier item in the sequence?

Is it the same as _.sequence-item-5 ?

Is there a declaration of _ anywhere that I can look at?

If I have a name clash (two Z SQL Method's return ID), how to I look up the
stack of namespaces?

Yours in abject confusion,
