Sorry Tres but your solution is not so much minimalistic as I spect I prefer the Gaël solution but I don't understand so much Where do I need to put this line? At my product code? Where, please? Thanks both!!!!!!! 2007/4/9, Tres Seaver <tseaver@palladion.com>:

Hi!! I have a method in my product called freemind wich generate the xml to the freemind applet but on this applet is mandatory to use the .mm extension

Is possible to create a product function with extension? (in this case will be something like freemind.mm)

You could do it with a dirty setattr(self, "myfunction.mm", self.myfunction).

But I would say the cleanest way is to use the Content-Disposition HTTP header:

Content-Disposition: attachment; filename=myfunction.mm

(with REQUEST.RESPONSE.setHeader).

See http://www.ietf.org/rfc/rfc1806.txt for more information on it.

You could also register a browser view which uses your method. E.g., to implement the view::

# Produts/foo/browser.py from Products.Five import BrowserView class FreemindView(BrowserView): def __call__(self, *args, **kw): self.request.RESPONSE.setHeader('Content-Type', 'text/xml') return self.context.freemind()

and then register the view

<!-- Products/foo/configure.zcml --> <configure xmlns="http://namespaces.zope.org/zope" xmlns:browser="http://namespaces.zope.org/browser">

<browser:page for=".interfaces.IFreemindProvider" name="freemind.mm" class=".browser.FreemindView" permission="zope.Public" />

The registration assumes that your content class implements an 'IFreemindProvider' view, which might be defined as:

# Products/foo/interfaces.py from zope.interface import Interface class IFreemindProvider(Interface): """ Document it here. """ def freemind(): """ Document the method here. """

Your content class would then declare that it implements it, e.g.:

# Products/foo/content.py from zope.interface import implements from Products.foo.interfaces import IFreemindProvider

class FooContent(...): implements(IFreemindProvider) ....

Once set up this way, assuming that yo have a FooContext instance with the URL, 'http://example.com/path/to/foo', then you could point the browser to 'http://example.com/path/to/foo/freemind.mm' to get the XML.
