[Grok-dev] Using five.grok to add new viewlets

[Vincent Fretin]

Hi,

After changing my code according to Sylvain suggestions to:
grok.templatedir('templates')

class AdViewlet(grok.Viewlet):
    grok.baseclass()
    grok.template('adviewlet')
    def getBanner(self): pass

class AdHomeViewletManager(grok.ViewletManager):
    grok.name('admanager.home')

class AdHomeViewlet(AdViewlet):
    grok.viewletmanager(AdHomeViewletManager)

I had the following error:
TraversalError: (<Products.Five.metaclass.Plone object at 0xe2e3f90>,
'getBanner')
It's because I used view/getBanner instead of viewlet/getBanner in my template.

Why with my old code, I can do view/getBanner, it means view variable
is the viewlet here. It's normal or a bug?
My old code:
from Products.Five.browser.pagetemplatefile import ZopeTwoPageTemplateFile
class AdViewlet(grok.Viewlet):
    grok.baseclass()
    template = ZopeTwoPageTemplateFile('templates/adviewlet.pt')
    def render(self):
        return self.template()


Sylvain, after reading the ftests, I understood how grok.PageTemplate
is supposed to work. Nice.
