Why Laravel-json-api update does not work?

Question

I created an API with the Laravel-json-api framework, with no controller, since the framework do all the job.

It works fine with index and read, not with update.

I use Postman to do an update, but it returns the record in the DB, without any change, nor any error message.

the api.php file :

JsonApi::register('v1')->routes(function ($api) {
        $api->resource('titre')->only('index', 'read', 'update');
});

To update the titre record, I use /localhost/api/v1/titre/777777
I use Postman, with the right Content-Type : application/vnd.api+json

And here is my Postman's raw body :

{
     "data": {
        "type": "titre",
        "id": "777777",
        "attributes": {
            "ACTIF": "O",
        },
        "links": {
            "self": "http://localhost/api/v1/titre/777777"
        }
    }
}

I expect the API to update the ACTIF attribute, but I get as a result :

{
     "data": {
        "type": "titre",
        "id": "777777",
        "attributes": {
            "ACTIF": "D",
        },
        "links": {
            "self": "http://localhost/api/v1/titre/777777"
        }
    }
}

No error message, or anything, but the ACTIF attribute, which should be updated from D to O, is not updated.

According to the Laravel-json-api documentation, this should work, right ? Can someone tells me where is my error ?

Answer 1

What you are facing might be caused by several reasons. Please check these points:

• Make sure that you are using PATCH HTTP method for updates. JSON:API specification explicitly requires PATCH for updates.
• Make sure that ACTIF attribute is fillable if you are using Eloquent Adapter. Laravel JSON API relies on mass assignment feature.

If this doesn't work, please include a curl request in your question as it helps us to reproduce your request.
