[Zope] How to convert string to object?

07 Mar 2003 00:07:32 -0600

If your asking that question there is a possibility that you don't
understand zope acquisition. Which is all right ... I think we all
didn't get it at one point.

I assume you want to use index_html as a template (or wrapper) for the
content in some deeper folder?

If so all you need to do (sorry this is in zpt ... don't use dtml much
anymore)...

in a zpt in your root folder  ..

<html>
  <body>
    <div>
      or table or what not containing whatever you 
      want to appear before the "content"
    </div>
    <div tal:content="structure here/content"/>
    <div>
      or table or what not containing whatever you 
      want to appear after the "content"
    </div>
  </body>
</html>

Now just create folders ... and stick a file (dtml or zpt or python
script or whatever) called 'content' wherever you want it to appear.

So if I had a folder layout like the following: 

/articles/linux/2003/03/07/01

I would put a zpt (or dtml document/method) called 'content' in the
/articles/linux/2003/03/07/01 folder.

And when I surfed to:

http://server/articles/linux/2003/03/07/01

I would get the content file 'wrapped' with the index_html somewhere up
the folder 'path'.

You can further customize things by using macros and slots and all the
zpt goodies. Plus if you ever need to 'override' your index_html file
deeper in you folder 'tree' just create a new one at the highest level
you want to start using it.

Hope this helps
