[Zope3-dev] difference between view and page

[Garrett Smith]

I've read through the documentation in view.stx and page.stx, but I'm
not clear on their differences.

The issue never bothered me until I saw the following in
zope/app/browser/traversal.zcml:

<view
    for=3D"*"=09
    name=3D"absolute_url"
    factory=3D".absoluteurl.AbsoluteURL"
    type=3D"zope.publisher.interfaces.http.IHTTPPresentation"
    permission=3D"zope.Public"
=20
allowed_interface=3D"zope.app.interfaces.browser.absoluteurl.IAbsoluteURL=
"

    />

<browser:page
    for=3D"*"
    name=3D"absolute_url"
    class=3D".absoluteurl.AbsoluteURL"
    permission=3D"zope.Public"
=20
allowed_interface=3D"zope.app.interfaces.browser.absoluteurl.IAbsoluteURL=
"

    />

Similar, but different :-)

Docs state that a view "defines a view that has subpages". Docs state
that a page "is used to create views that provide a single url or page".

Pages aren't strictly used for URLs as is illustrated by the use of
absolute_url for breadcrumbs -- the "page" merely provides methods that
are useful in page renderings.

And views aren't strictly used to define subpages, as is illustrated by
the view empty element above (no subpages).
