Using the value of a relationship fieldtype in collection routes

[duncanmcclean]

We have a custom Relationship fieldtype which we'd like to use in our collection route like so but it doesn't seem to work...

route: '/locations/{location:slug}/apartment-types/{slug}'

But this does work (without the :slug bit)

route: '/locations/{location}/apartment-types/{slug}'

We are returning an augmented array from our custom Location fieldtype - it returns the augmented array from an entry.

Is there any way to workaround the issue we're running into (without having to build custom routes?)

I wasn't been able to find the solution other that custom template which retrieves the entries from the collections by their slugs.

You can workaround this by creating a Computed Value to return any related fields you want to use in your collection route.

For example, you could do something like this:

Collection::computed('locations', 'location_slug', function ($entry, $value) {
    return $entry->entries_field->slug();
});

Then, the collection's route would use that computed value like this: /locations/{location_slug}/{slug}.

If you want this to be supported in future version of Statamic, add a 👍 reaction to this feature request: statamic/ideas#360

Oh, that's I haven't realized there is such a way. I'll give it a try. Feature request is also handy, upvoted!
Thank you very much for the hint

No worries! Hope it works - have a great rest of your day.
