[Flow] Question regarding deleted objects

[Marc Neuhaus]

You could simply use the object and user as argument for the link. In the
default case
where the objects exists you can show the object, otherwise you could
directly forward
to some page of that user.

As a concrete example, if you'd have some hosted "blogging" platform, you
routes could look like this:

    /blog/[someUserName]/[somePostName]

That username + postname would correspond to some uuid of course, so now
you could model your action somethink like this:

    if (post does not exist) {
        redirect to user overview
    }

    show post

I hope i explained my idea properly :)

Cheers
Marc
