plone - Do some Zope 3 resources take parameters from the URL? -


in plone 4, have custom dexterity content type has namedblobfile field called audio_artifact. when using default edit view edit type, see urls this:

enter image description here

what's going on here? i'm familiar zope 3 resources in general, here looks widget resource being passed @@download view parameter. correct? or confused. suspect latter.

++something++ traversal namespace, it's not resource per se, ++resource++ instead namespace. namespaces custom namespace handlers, given rest of item name.

in case widget namespace handler given name of widget, forms.widgets.audio_artifact, , use widget on add form.

@@download view on widget, enables download file in widget. images there view allows thumbnails etc.
