Configuration and Usage

Setting up Relationships

One-to-Many Relationship:

In the 'many' side collection's blueprint (e.g., Episodes), create an 'Entries' fieldtype (e.g., series) with a maximum of one entry, pointing to the 'one' side collection (e.g., Series).

Many-to-One Relationship:

In the 'one' side collection's blueprint (e.g., Series), add the Reverse Relationship fieldtype with a configuration pointing to the 'many' side collection (e.g., Episodes) and the specific relationship field (e.g., series).

Example: Series and Episodes

Episodes Collection Blueprint:
Add an 'Entries' fieldtype named 'series', limited to 1 entry, linked to the Series collection.

Series Collection Blueprint:
Add a Reverse Relationship fieldtype named 'Episodes', configured to the Episodes collection and the 'series' field.

In Templates

Fetch related entries in Antlers templates using the Reverse Relationship field:


{{  collection:series }}


    {{  title }}<br>


    <ul>


        {{ episodes scope="episode" }}


            <li>{{ episode:title }}</li>

        {{ /episodes }}

    </ul>


{{  /collection:series }}

Limitations

The addon does not support many-to-many relationships.
Correct setup of relationship fields in collections or taxonomies is crucial for proper functionality.
