Creating Record With Related Morph One

[yoelpc4]

I have Project model morph one to Document model

app/Models/Project.php

    /**
     * Project morph one contract document
     *
     * @return \Illuminate\Database\Eloquent\Relations\MorphOne
     */
    public function contractDocument()
    {
        return $this->morphOne(Document::class, 'documentable');
    }

app/Models/Document.php

    /**
     * Document morph to documentable
     *
     * @return \Illuminate\Database\Eloquent\Relations\MorphTo
     */
    public function documentable()
    {
        return $this->morphTo();
    }

with relation registration in adapter

app/JsonApi/v1/Projects/Adapter.php

    /**
     * Project morph one contract document
     *
     * @return \CloudCreativity\LaravelJsonApi\Eloquent\HasOne
     */
    protected function contractDocument()
    {
        return $this->hasOne();
    }

When creating project via [POST] https://api.test/v1/projects with payload

{
    "data": {
        "type": "projects",
        "attributes": {
            "name": "1st project",
        },
        "relationships": {
            "contractDocument": {
                "data": {
                    "type": "documents",
                    "id": "90"
                }
            }
        }
    }
}

I got an internal server error (500) when creating record with message

JSON API relation HasOne cannot be used for an Eloquent MorphOne relation

Do you have any idea?

Thanks for this. Morph one probably isn't supported just because it has been introduced since I wrote the code. I need to add tests for this scenario to check that it works, and bug fix it if it doesn't.

This is definitely a missing feature. I've added it and it will be tagged as 1.7.0 and 2.0.0-beta.3.
