[Zope] Grrr for ZPT and python product

Thu, 04 Apr 2002 15:22:04 +0100

I have many difficulties using ZPT for python product development. METAL in 
fact.

The templates are called like this:

PTF = PageTemplateFile
StandardLook = PTF('zpt/StandardLook', globals())
AddIssue = PTF('zpt/AddIssue', globals())
index_html = PTF('zpt/index_html', globals())

AddIssue.zpt starts like this:
<html metal:use-macro="here/StandardLook/macros/standard">

    <div metal:fill-slot="body">

Below is the cryptic error message. So I visited the StandardLook object on 
its own by going to:
http://localhost/instance/StandardLook. and that works just fine.
If I remove the metal: attributes from AddIssue.zpt it works fine but lacks 
the header and footer.
I.e., they work fine independently but not together.
It works fine for index_html.zpt though.

My main question is how to get more useful error messages when using ZPT 
templates??
And why is it that sometimes StandardLook.zpt gets the blame when the error 
actually is in index_html.zpt?
How do I make my ZPT python product development easier? What tools are 
available? What hacks? What tricks?

Zope 2.4.0 Windows
PageTemplates 1.4.1
