Custom page copy that does NOT copy the original page's revisions

Notes.txt

The tricky bit is then getting that view used for the "copy". 
We do a lot of patching so it's hard for me to extract a good example of that 

urls.py

from django.urls import path

from .. import views


urlpatterns = [
    path('<int:page_id>/event-page-copy/', views.event_page_copy, name='event_page_copy'),
]

views.py

@user_passes_test(user_has_any_page_permission)
def event_page_copy(request, page_id):
    """
    This short-circuits the normal Page copy flow for EventPages specifically by skipping the intermediate page
    that allows you to choose a title, page parent, slug and whether you want to publish the page.  This is used
    by the per-page [COPY] links on the My Events page.

    Instead we:

        * Set the parent to the master calendar page
        * Autogenerate a valid slug
        * Set the page title to the same title as the origin page

    Because of these assumptions, we specifically look for EventPages with id `page_id` and 404 if they're not found.

    if not page.permissions_for_user(request.user).can_copy_to(parent_page, False):
        raise PermissionDenied

    new_slug = slugify(page.title, allow_unicode=True)

        new_slug = safe_slugify(page, parent_page)
