I want to change my website's header only it if's not the homepage. Is there a tal:condition expression for that?
I've been reading this and can't find what I'm looking for...
thanks!
how about something like <tal:condition="python: request.URLPATH0 == '/index_html'
...>`? see TALES Built-in Names and the Zope API Reference for more choices.
The best way is to use two really handy plone views that are intended just for this purpose. The interface that defines them is at https://svn.plone.org/svn/plone/plone.app.layout/trunk/plone/app/layout/globals/interfaces.py, in case you want to check it out.
The great thing about @@plone_context_state and @@plone_portal_state is that they handle all sorts of weird edge cases. context/@@plone_context_state/canonical_object_url also returns the right, most basic, object's url even when you're viewing the default page in the portal root with a query string appended :-)
