[Zope3-Users] Setting custom content type when publishing a resource

[Andrew Groom]

Hi Frank,

Thanks for the ZCML, but I'm still having problems. Here's what I have 
so far:

configure.zcml:

<configure xmlns:browser="http://namespaces.zope.org/browser">
	
	<browser:page
		for="*"
		name="vortexgdna.xpi"
		class=".xpipublisher.XPIPublisherView"
		permission="zope.View"/>

</configure>

(It complained if I didn't have the "for" attribute in there, btw)

xpipublisher.py

from zope.app.publisher.browser import BrowserView

class XPIPublisherView (BrowserView):

     def __call__(self):
         self.request.response.setHeader('Content-Type', 
'application/x-xpinstall')
         return self.context.data


When I try to access http://(domain)/vortexgdna.xpi, I get:

   File "(snip)/xpipublisher.py", line 8, in __call__
     return self.context.data
ForbiddenAttribute: ('data', <zope.app.folder.folder.Folder object at 
0x4129aaac>)

So, self.context is a folder object. The file that I'm publishing is 
coming from the filesystem - could that be the problem ?

Cheers, Andrew.
