This document discusses pyramid_zope_request, a Python package that allows Zope-based packages to be used with the Pyramid web framework. It implements PyramidRequest and PyramidResponse objects that mimic the Zope publisher request and response interfaces. This allows Zope forms and other publisher-based packages to work with Pyramid. As an example, it shows how to use the z3c.form package with Pyramid through pyramid_zope_request.

z3c.form example
As proof of concept, z3c.form works
class IMyLayer(
z3c.form.interfaces.IFormLayer,
IBrowserRequest):
pass

z3c.form example
Just better to use chameleon templates
person.pt:
...
<label tal:attributes="for widget.id"
tal:content="widget.label">
label
</label>
<input type="text" size="24" value=""
tal:replace="structure widget.render()"/>
...
