How to hide relation attributes?

[robertogallea]

Hi, I am not able to hide specific attributes from relations. I have tried the following:

1. in User set $gdprHidden = ['relation.attribute']

2. Add Portable trait to Relation and inside it set $gdprHidden = ['attribute']

What am I missing? Thank you.

Hi there,

Number one will not work. Number two does work, but you forgot to implement the PortableContract on the relation.

Thank you for your reply. However I still have some problems.

I tried also what you told, but I thought it was uncorrect, since I got an exception.

I have the following (simplifying):

class User extends Authenticable implements PortableContract
{
    use Portable;

    protected $gdprWith = ['relation'];

    protected $gdprHidden = ['password', 'remember_token', 'created_at', 'updated_at'];   

    public function relation()
    {
        return $this->hasOne(Relation::class);
    }

    public function getNameAttribute()
    {
        return ucfirst(strtolower($this->person->name)); // <-- HERE LIES THE PROBLEM
    }

   ...
}

and

class Relation extends Model implements PortableContract
{
    use Portable;

    protected $gdprHidden = ['id'];
    
    ...
}

with this setup I get the following exception:

Property [name] does not exist on this collection instance.

where name is an (existing) attribute of Relation used by an accessor in User

It seems that, notwithstanding it is a hasOne relation, your package loads it as a Collection instead of a single object, so the accessor fails.

If a remove Relation from $gdprWith the relation is correctly loaded but no filtering is performed on the attributes. Any ideas why relations are always load as a Collection?

It seems like the Portable trait lacks hasOne and belongsTo support. Unfortunately, I don't have time to fix this properly this week.

Feel free to use the following workaround for the time being. I'll get back to you with a new release.

    /**
     * Load and transform a portable relation.
     *
     * @param  string  $relation
     * @return void
     */
    private function loadPortableRelation(string $relation)
    {
        $items = $this
            ->$relation()
            ->get()
            ->transform(function ($item) {
                return $item->portable();
            });

        if ($items->count() === 1) {
            $items = $items->first();
        }

        $this->attributes[$relation] = $items;
    }
