Re: [Cheetahtemplate-discuss] recipe for extending/subclassing a dynamically generated template class

[Jose G. <jo...@cy...>]

Can someone please tell my why this does not work in a template, I
thought it should but it does not

================
#set base = Template.compile(file='chTemplates/base.tmpl'))
#from $base import base
#extends base
the rest of the template

If I comment out the above code the template compile just fine.
