Relationship hasMany doesn't work

[willypuzzle]

I have this objects stored on mongodb:

Client:

{
	"_id" : ObjectId("581af4fbf53b09175210c2dc"),
	"created_at" : ISODate("2016-11-03T08:27:39.675Z"),
	"updated_at" : ISODate("2016-11-03T08:27:39.675Z"),
	"url" : "francesco.ragusa.local",
	"safe" : false,
	"attributes" : [ ],
	"enabled" : true,
	"__v" : 0
}

MessageSender:

{
	"_id" : ObjectId("581c583440135d1e581ec58e"),
	"created_at" : ISODate("2016-11-04T09:43:16.639Z"),
	"updated_at" : ISODate("2016-11-04T09:43:16.639Z"),
	"owner" : ObjectId("581af4fbf53b09175210c2dc"),
	"type" : {
		"information" : null,
		"name" : "operator"
	},
	"nickname" : "Giusipuzzu",
	"enabled" : true,
	"__v" : 0
}

And this classes on laravel:

class Client extends Eloquent
{
    protected $connection = 'mongodb';

    public function messageSenders(){
        return $this->hasMany(\App\Models\MessageSender::class, 'owner');
    }
}

class MessageSender extends Eloquent
{
    protected $connection = 'mongodb';

    public function client(){
        return $this->belongsTo(\App\Models\Client::class, 'owner');
    }
}

Where Eloquent is an alias of 'Jenssegers\Mongodb\Eloquent\Model'.

If I do:

MessageSender::find('581c583440135d1e581ec58e')->client 

I got the right object.

But if I do:

Client::find('581af4fbf53b09175210c2dc')->messageSenders

I got a instance of 'Illuminate\Database\Eloquent\Collection' but empty.
I think hasMany relationship doesn't work properly.

I have the same issue. Any updates on above, anyone?

I believe your issue here is that 'owner' isn't the foreign key for both relationships, and thus, should not be the 2nd parameter in both instances. For MessageSender, it is the local side of the key, and '_id' is the foreign side (Client).
