Laravel滔滔不绝地向很多人回报空洞

Question

So i'm trying to get my head around using eloquent for many to many relationships in my application.

I have three tables as followed

   user
    +----------------+------------------+------+-----+---------------------+----------------+
    | Field          | Type             | Null | Key | Default             | Extra          |
    +----------------+------------------+------+-----+---------------------+----------------+
    | id             | int(10) unsigned | NO   | PRI | NULL                | auto_increment |
    | first_name     | varchar(255)     | NO   |     | NULL                |                |
    | last_name      | varchar(255)     | NO   |     | NULL                |                |

    +---------------+----------------------------+------+-----+---------------------+----------------+

in my user repository i have the following

namespace App\Libraries\Repositories\Core\Users;

use Schema;
use App\Models\Core\User;
use Bosnadev\Repositories\Eloquent\Repository;
use Symfony\Component\HttpKernel\Exception\HttpException;

class UserRepository extends Repository
{
    public function getUsersAddresses()
    {
        return $this->userModel->hasManyThrough('App\Models\Bundle\Addresses\Address','App\Models\Bundle\Addresses\UserHasAdress','id','address_id');
    }
}

Im returned an object that shows parent and related classes but im not actually returned my users address. Is there something im missing?

Answer 1

Alexrussell made some good points in his comment that you could possibly address, however I believe your immediate problem is a missing ->get() at the end of your return line.

Without it, you would be required to call your method like:

$repository->getUsersAddresses()->get();

As hasManyThrough will return an instance of Illuminate/Database/Eloquent/Relations/HasManyThrough not the actual results

For reference: https://laravel.com/api/5.2/Illuminate/Database/Eloquent/Relations/HasManyThrough.html

Note in the example here: https://laravel.com/docs/5.1/eloquent-relationships#many-to-many

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    /**
     * The roles that belong to the user.
     */
    public function roles()
    {
        return $this->belongsToMany('App\Role');
    }
}

The example usage includes a get(): $roles = App\User::find(1)->roles()->orderBy('name')->get();

Hope this helps
