[ZPT] AttributeError using METAL outside of Zope

Tue, 3 Dec 2002 12:08:17 -0800

Hi,

Using PageTemplates 1.5 with Python 2.2.2 I get an AttributeError on the id of the macro. Below is an interactive session based on an earlier posting to this list. (Note: the PageTemplate class _is_ subclassed from Base, so this seems to be a different problem). Thanks.

Francis

>>> pt = PageTemplate()
>>> template_file = open('d:/website/page.html')
>>> pt.write(template_file.read())
>>> template_file.close()
>>> pt.read()
'<html metal:use-macro="options/standard_page/macros/master">\n\t<div metal:fill-slot="main">\n\t\t<p><b>Inner Page</b></p>\n\t</div>\n</html>\n'
>>> standard_page = PageTemplate()
>>> template_file = open('d:/website/standard_page.html')
>>> standard_page.write(template_file.read())
>>> template_file.close()
>>> standard_page.read()
'<html metal:define-macro="master">\n\t<p>Outer page</p>\n\n\t<div metal:define-slot="main">\n\t</div>\n</html>\n'
>>> pt(standard_page=standard_page)
