[Grok-dev] cheetah templates

[Milos Negovanovic]

Hi,

Fallowing this tutorial -> http://grok.zope.org/documentation/how-to/plugging-in-new-template-languages
I have these 2 classes:

class CheetahTemplate(grok.components.GrokTemplate):
    def setFromString(self, string):
        self._template = Template.compile(source=string)

    def setFromFilename(self, filename, _prefix=None):
        self._template = Template.compile(file=os.path.join(_prefix, filename))

    def render(self, view):
        return self._template(searchList=[{'view': views}]).respond()


class CheetahTemplateFactory(grok.GlobalUtility):
    grok.implements(grok.interfaces.ITemplateFileFactory)
    grok.name('tmpl')

    def __call__(self, filename, _prefix=None):
        return CheetahTemplate(filename=filename, _prefix=_prefix)

This throws the fallowing error when starting grok/zope:

Where can I find recent tutorial on this subject? GrokTemplate has
obviously been moved.
