cannot retrieve Category model with related items - php

Question

I have very strange error in my laravel website.
I try to retrieve Category model with related items, but looking at the error I see that laravel tries to retrieve items field from category model and of course it fails. But I am completely cannot understand why it happens, because I have the same code working well in other parts of my website.
routes/web.php
Route::name('gallery.')->prefix('gallery')->group(function () {
Route::get('/', 'GalleryController#index')->name('index');
Route::get('/{slug}', 'GalleryController#item')->name('item');
});
GalleryController
public function item($slug)
{
$category = $this->imageRepository->getCategoryWithPaginatedImages($slug, $perPage = 20);
return view('pages.gallery.item', compact('category'));
}
ImageRepository
namespace App\Repositories;
use Illuminate\Database\Eloquent\Collection;
use App\Models\ImageCategory as Model;
class ImageRepository extends CoreRepository
{
protected function getModelClass()
{
return Model::class;
}
public function getCategoryWithPaginatedImages($slug, $perPage = null)
{
$columns = ['id','title','slug','description','image','published','metatitle','metakey','metadesc'];
$result = $this
->startConditions()
->whereSlug($slug)
->select($columns)
->with('images:id,title,category_id,md,lg')
->firstOrFail()
->toArray();
$result = Arr::arrayToObject($result);
$result->items = collect($result->items)->mypaginate($perPage);
return $result;
}
}
Image
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Image extends Model
{
protected $guarded = [];
public function category() { return $this->belongsTo(ImageCategory::class); }
}
ImageCategory
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class ImageCategory extends Model
{
protected $guarded = [];
public $timestamps = false;
public function images() { return $this->hasMany(ImageCategory::class, 'category_id'); }
}
so when I hit gallery/slug then getCategoryWithPaginatedImages gives me following error
Illuminate\Database\QueryException
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'category_id' in 'field list' (SQL: select `id`, `title`, `category_id`, `md`, `lg` from `image_categories` where `image_categories`.`category_id` in (2))

Answer 1

I guess the relationship images on ImageCategory definition has an issue, should be as under
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class ImageCategory extends Model
{
protected $guarded = [];
public $timestamps = false;
public function images()
{
return $this->hasMany(Image::class, 'category_id');
}
}
