Why not read/print "Polymorphic To-Many Relations"

[joserick]

Hi,

I have a problem with this relationship:

class Banner extends Model
{
    /**
     * Get all of the series for the banner.
     */
    public function series()
    {
        return $this->morphedByMany(Serie::class, 'bannerable')
            ->using(Bannerable::class)
            ->withPivot('id');
    }

    /**
     * Get all of the readlists for the banner.
     */
    public function readlists()
    {
        return $this->morphedByMany(Readlist::class, 'bannerable')
            ->using(Bannerable::class)
            ->withPivot('id');
    }
}

and in "BannerSchema" i have:

public function fields(): array
    {
        return [
            ID::make(),
            Str::make('name')->sortable(),
            MorphToMany::make('media', [
                BelongsToMany::make('series'),
                BelongsToMany::make('readlists'),
            ]),
        ];
    }

But in the response of the endpoint not show anything respect to the relationship:

{
    "jsonapi": {
        "version": "1.0"
    },
    "data": [
        {
            "type": "banners",
            "id": "1",
            "attributes": {
                "name": "Banner 1"
            },
            "relationships": {
                "media": {
                    "links": {
                        "related": "http://localhost/api/v2/banners/1/media",
                        "self": "http://localhost/api/v2/banners/1/relationships/media"
                    }
                }
            },
            "links": {
                "self": "http://localhost/api/v2/banners/1"
            }
        },
    ]
}

I don't understand what I'm doing wrong, could someone guide me?

You need to use an include path to request the inclusion of related resources, e.g. /api/v1/banners?include=media

Here it is in the spec:
https://jsonapi.org/format/#fetching-includes

@lindyhopchris I encountered a similar issue. I've created a separated issue #280.
