[ZPT] Re: Dynamic title for template?

27 Apr 2001 17:04:17 +0000

Well, in case anybody's curious, here's what I ended up doing:

In the standard template, I define a local variable title at the top
of the file:

<html metal:define-macro="master"
      tal:define="title template/findTitle">

then I use that variable wherever I want to insert the title

findTitle is a Python script that I added to the top folder of the
site.  It starts at the template and recursively goes up the ZODB
hierarchy looking for the first non-empty title:

title = context.title

# The following allows me to put "title" python scripts into my
# ZClasses to dynamically generate the title.
if callable(title):
  title = title()

if title == "":
  title = context.getParentNode().findTitle()

return title

This seems to work OK for both static string titles and dynamic script
titles. :-)
