Re: [Zope3-Users] Re: ZopeX3 Component Architecture in comparision to MVC - general question/example
Hi Reinhold,
Here's another go at answering your case, this came about when last
night I added a source view to a RESTDocument content, it might come
closer to what you are looking at because it doesn't use tal templates
at all and secondly the request is available - so you can pass in
arguments to your calculator. My starting point for the code is from
zope.app.file.browser.file.
Best regards,
Darryl
class PortalRestDocumentSourceView(BrowserView):
"""A RestDocument source view."""
def show(self):
"""Call the source view of restdocument"""
request = self.request
if request is not None:
request.response.setHeader('Content-Type',
'text/plain')
return self.context.body

Hi Reinhold,
Here's a go at answering your problem. I gather you don't even need a
component as such - just a piece of code to perform a calculation. I
borrowed a technique from SchoolBell which may help. I think it may help
because it provides a way of performing any variety of python code
within a tal template without using python in the template. Any method
added to TFWSAPI can be accessed in tal with 'tfws:mymethod'. I've not
used XMLRPC calls with Zope so I'm not sure how it will translate. Good
luck.
Best regards,
Darryl
class TFWSAPI(object):
"""TALES function namespace for TFWS specific actions.
Borrowed from SchoolBell.
"""
implements(IPathAdapter, ITALESFunctionNamespace)
def __init__(self, context):
self.context = context
# as example
def authenticated(self):
"""Check whether context is an authenticated principal.
Sample usage in a page template:
User title
Anonymous
"""
if not IPrincipal.providedBy(self.context):
raise TypeError("tfws:authenticated can only be applied"
" to a principal")
return not IUnauthenticatedPrincipal.providedBy(self.context)
authenticated = property(authenticated)
