Re: [Zope] Changing Properties With ZPT
Thanks for the reply, Andreas. Actually, I probably didn't properly explain my question. I do realize that the template is an object and that all I need to do is access the template's API to modify it's properties (though, I admit I'm a newbie here). My problem is that the only way I can find to access the template object is through ZPT's built-in variable 'template'. Since I'd like to change the property, it seems like I'll need to use a python line that uses the template's manage_changeProperties() method. I'm just not sure what the python equivalent of the ZPT 'template' variable is. An example is probably in order. Take the following code: div tal:content=template/titleTITLE HERE/div div tal:content=python:context.titleTITLE HERE/div The first line does what I'd like it to do, it returns the 'title' property of the template. The second line doesn't. It returns the 'title' property of the template's container. How do I make the second line do the same thing as the first line. If someone can give me that, I'll know how to do the rest. Thanks for the On Wed, 2005-08-10 at 09:00 +0200, Andreas Jung wrote: --On 9.

why not using the same name in the python expression? :-)
div tal:content=python: template.titleTITLE HERE/div
just beware that the path expression template/title might do some magic for
you, like calling a method, or accessing a dictionary etc. if in doubt, you
can always do
div tal:content=python: path('template/title')TITLE HERE/div
