Laravel one-to-one polymorphic relationships

Asked by: user8286420

Right now I have a model created from this database migration:

Schema::create('likes', function(Blueprint $table)
{
    $table->increments('id');
    $table->integer('user_id')->unsigned();
    $table->integer('object_id')->unsigned();
    $table->string('object_type');
});

After reading other answers about it I tried playing with morphTo and morphOne but I can't seem to figure out how they'd work in this context.

Basically I want to define a function for each type of object that can be referenced by object_type like so:

public function message()
{
    return $this->hasOne('App\Message', 'id', 'object_id');
}

public function status()
{
    return $this->hasOne('App\Status', 'id', 'object_id');
}

But with the restriction that the function returns null if object_type isn't App\Message or App\Status respectively.
