It is, of course, better if you can structure your app so you don't have 
to pull the request "out of thin air", but if you do, I'd be a little 
more careful about it.  Like so:

def getRequest(): 
 
 

     i = zope.security.management.getInteraction() # raises 
NoInteraction 
 


     for p in i.participations: 
 
 

         if IRequest.providedBy(p): 
 
 

             return p 
 
 

 
 
 

     raise RuntimeError('Could not find current request.')
