I used turbogears 2.3.10 with kajiki template, I created applicantion name samples and created pluggable application name plugapp. (I see in http://turbogears.readthedocs.io/en/latest/turbogears/Pluggable/index.html?highlight=plugin)
I created package name master_view(templates/master_view) and file master.xhtml in plugapp(pluggable application).
-plugapp
--templates
--master_view
--master.xhtml
--index.xhtml
In index.xhtml of plugapp(pluggable application), I changed
<py:extends href="master.xhtml"/>
to
<py:extends href="master_view/master.xhtml"/>
I run http://localhost:8080/plugapp. it show error
TypeError: coercing to Unicode: need string or buffer, NoneType found .
How do I fix it? thank you.
