[BlueBream] security on links

[Ilshad Khabibullin]

browser:menu and viewlets have this behavior out the box, viewlet are more
component I think.

But often you need more custom decisions, then you have
zope.security.canAccess or other zope.security API methods.

This is example from code which iterates on contained objects and it shows a
links in these contexts (i.e. forums):

adminLinks = getMultiAdapter((self.context, self.request, self),
IContentProvider, name='links')
...
for forum in self.context.values():
    ...
   yield {...
'adminLinks': zope.security.canAccess(adminLinks, 'render') and
adminLinks.render(forum) or u''
 }

These IContentProvider adapters are declared in zcml with permissions and
`locate="True"`. Then that links displayed when defined permission allowed
on the a forum.
