RE: [Zope] ZPT equivalent to the global HTML() ?

7 Aug 2003

      Hello,

This works great! Now I have a funny bit of a problem though, not a big deal
, but a nice to have.

I have a template like this:

<html metal:use-macro="here/main_template/macros/master">

<p metal:fill-slot="main">

<span tal:replace="structure here/CookedBody" />

</p>

</html>

(CookedBody is extended to render ZPT, as suggested).

The problem now is that the ZPT/TAL/TALES is evaluated in it's own world,
seperatly from the main_template, which tal:define's variables I'd like to
use inside CookedBody/EditableBody code (i.e. main_template has <html
tal:define="variable expression">, but that variable isn't accessible when
CookedBody is rendrered)

Is this possible?

Another way to put it: Would it be possible to get the tal:replace to
actually pt() render the content of the returned structure ? This way I
could skip making the Document ZPT aware altogether (One less Monkey Patch),
AND I'd have access to my variables (less repeated method calls) ...

Any insight on how to accomplish something like this would be greatly
appreciated!

Thanks,
J.F.

Now, I'm thinking of switching to using ZPT's, but am having a harder
time
figuring out exactly what function/method I should use ... there's
pt_render, but that's a method that expects an object of the proper class
to
be passed (I think?) ... Which doesn't really work in my case ... I'd
like
to be able to simply feed the "text" to a function, along with a context,
REQUEST object, or something like that, and get the results.
Its a bit more complex with ZPT than with DTML because a
PageTemplate uses context from acquisition while all context must
be explicitly passed in to DTML.

It looks somehow like:

   from Products.PageTemplates.ZopePageTemplate import ZopePageTemplate

   pt= ZopePageTemplate('',template_source,content_type).__of__(context)
   rendered= pt() # render it
