Я создаю новостной портал для администратора.Я хочу создать раздел менеджера категорий. Я создал менеджер категорий, но пока я отправляю форму, я получаю следующие ошибки:
SQLSTATE [42S22]: столбец не найден: 1054 Заголовок неизвестного столбца'в' предложении где '(SQL: выберите количество (*) в качестве агрегата из categories, где title = Непал)
таблица миграции для категории:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateCategoryTable extends Migration
{
public function up()
{
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->timestamps();
$table->string('title',255);
$table->string('slug',100)->unique();
$table->text('image')->nullable();
$table->boolean('status')->default(0);
});
}
public function down()

У меня естьсоздал модель следующим образом: Models Category.php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Category extends Model
{
protected $table = 'categories';
protected $fillable = ['title', 'slug', 'image', 'status'];
}
