I am adding data to mongoDb using laravel :

In Model: Banner.php

<?php

namespace App\Models\Mongo;

use Illuminate\Database\Eloquent\Model;

class Banner extends Model
{
    protected $connection = 'mongodb';
    protected $collection = 'banner';
    protected $guarded = ['_id'];
    public $timestamps = false;
    protected $fillable = [
        '_id',
        'url',
        'width',
        'height',
    ];
}

In Controller : BannerController.php

use App\Models\Mongo\Banner;
use MongoDB\BSON\ObjectId;
public function store(Request $request)
{
   Banner::create([
     '_id'   => new ObjectId(),
     'url'   => 'test.jpg',
     'width' => 960,
     'height'=> 300
   ]);
   return response()->json([
        'status' => 'success'
    ], 200);
}

ERROR : message: "Call to a member function prepare() on null"

Or I tried another way, instead of saving with model class I use Repositories : BannerRepository.php:

<?php
namespace App\Repositories\MongoDB;
use App\Models\Mongo\Banner;
use MongoDB\BSON\ObjectId;
class BannerRepository extends MongoDBBaseRepository
{
    public function model()
    {
        return Banner::class;
    }
}

In controller :

use App\Models\Mongo\Banner;
use App\Repositories\MongoDB\BannerRepository;
use MongoDB\BSON\ObjectId;

   /**
     * @var BannerRepository
     */
   protected $bannerRepository;

public function __construct(
        BannerRepository $bannerRepository
 ) {
        $this->bannerRepository = $bannerRepository;
}
public function store(Request $request)
{
   $this->bannerRepository->getModel()->create([
     '_id'   => new ObjectId(),
     'url'   => 'test.jpg',
     'width' => 960,
     'height'=> 300
   ]);
   return response()->json([
        'status' => 'success'
    ], 200);
}

ERROR : Return value of App\\Repositories\\MongoDBBaseRepository::getModel() must be an instance of Jenssegers\\Mongodb\\Eloquent\\Model, instance of App\\Models\\Mongo\\Banner returned"

I have tried two ways. And both error. Don't know where I did wrong. Please give me your opinion. I'm new to laravel so it's a bit difficult. Thank you

CodePudding user response：

Your model is extending Illuminate\Database\Eloquent\Model;

Try to use Mongo Jenssegers\Mongodb\Eloquent\Model;

Something like this:

<?php

namespace App\Models\Mongo;

use Jenssegers\Mongodb\Eloquent\Model;

class Banner extends Model
{
}
