Pull in Nested Related Content

Issue

I have a template (For a Host) that pulls in related content (For that Host’s Events). The second template pulls in related items to that Event (Hosts & Shows). When the Event template is used in a Events collection loop, the Hosts & Shows related content populates properly. When called inside the Host template, those related fields do not populate.

This is the Event Card Template

In it you’ll see there‘s 2 related templates for pulling in Hosts & Shows related to this event. This works when just displaying the Event template in a loop, but when this template is called inside another template, the related templates don‘t get populated.

It looks like you're creating relationships in both directions, which probably isn't ideal. I'd stick to one direction only.

For example, if you have Hosts and Shows, presumably a Show has one or more Hosts. In the Show master template, I'd create a relationship to Hosts.

Then if you want to have a list of shows on a host's page, for example, you'd filter Shows by host.slug (or whatever) matching your currently viewed Host.

Ok! I’ll try that!
