Question

在开发电子商务网站时，我的商店页面上有类别侧边栏，并且在实际服务器和本地服务器上一切正常。然后，我想添加一个品牌部分，其概念与类别部分相同。因此，每种产品都可以属于一个或多个类别以及一个或多个品牌。

添加品牌部分后，本地服务器上的所有内容也都运行顺利，但是当我要进行部署时，出现以下内存不足错误：

错误：

PHP Fatal error: Out of memory (allocated 3527409664) (tried to allocate 20480 bytes) in /app/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php on line 50

以下是我的相关文件和代码，如果需要，我将很乐意提供更多代码。希望有人可以帮助解决它。谢谢。

ShopController.php：

public function index()
{
    $pagination = 9;
    $categories = Category::all();
    $brands = Brand::all();

    if (request()->category) {
        $products = Product::with('categories')->whereHas('categories', function ($query) {
            $query->where('slug', request()->category);
        });
        $categoryName = optional($categories->where('slug', request()->category)->first())->name;
        $brandName = $categoryName;
    } else 

    if (request()->brand) {
        $products = Product::with('brands')->whereHas('brands', function ($query) {
            $query->where('slug', request()->brand);
        });
        $brandName = optional($brands->where('slug', request()->brand)->first())->name;
        $categoryName = $brandName;
    } else {
        $products = Product::where('featured', true);
        $brandName = 'Featured';
        $categoryName = 'Featured';
    }

    if (request()->sort == 'low_high') {
        $products = $products->orderBy('price')->paginate($pagination);
    } elseif (request()->sort == 'high_low') {
        $products = $products->orderBy('price', 'desc')->paginate($pagination);
    } else {
        $products = $products->paginate($pagination);
    }

    return view('shop')->with([
        'products' => $products,
        'categories' => $categories,
        'categoryName' => $categoryName,
        'brands' => $brands,
        'brandName' => $brandName,
    ]);
}

Brand.php：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;


class Brand extends Model
{
protected $table = 'brand';

public function products()
{
    return $this->belongsToMany('App\Product');
}
}

BrandProduct.php：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BrandProduct extends Model
{
protected $table = 'brand_product';
protected $fillable = ['product_id', 'brand_id'];
}
