仅查看laravel-8中指定注册id的数据

Question

这里我的数据库中有两个表，分别名为user和products，这里是user.php

public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->foreignId('current_team_id')->nullable();
            $table->text('profile_photo_path')->nullable();
            $table->timestamps();
        });
    }

使用这个表，我可以通过电子邮件地址注册和登录。登录后，它将我带到一个名为index.blade.php的页面，其中有一个名为add data的按钮，单击它后，它将把我带到我的create.blade.php页面，在那里我可以为products表注册一些数据。在注册数据之后，这些数据将在index.blade.php中显示。这很好，我可以添加数据，它会显示在索引中。没有问题。但问题是，当我从索引登录并使用新的电子邮件地址再次注册，并使用新的电子邮件地址登录时，它会显示我在以前的电子邮件中添加的旧数据。但是我不想在使用新的电子邮件地址登录后看到旧数据。这是我的product.php表

    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->text('detail');
            $table->string('color');
            $table->string('image');
            $table->string('logo');
            $table->timestamps();
        });
    }

这是我的ProductController.php

<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class ProductController extends Controller
{
    public function index()
    {
        if(Auth::check()){
        $products = Product::latest()->paginate(1);

        return view('products.index',compact('products'))

            ->with('i', (request()->input('page', 1) - 1) * 5);
        }
    }
    public function create()
    {
        return view('products.create');
    }

    public function store(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
            'color' => 'required',
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:640dp*480dp',
            'logo' => 'required|mimes:jpeg,png,jpg,gif,svg|max:512*512',
        ]);

        $input = $request->all();

        if ($image = $request->file('image')) {
            $destinationPath = 'image/';
            $profileImage = date('YmdHis') . "." . $image->getClientOriginalExtension();
            $image->move($destinationPath, $profileImage);
            $input['image'] = "$profileImage";
        }

        if ($logo = $request->file('logo')) {
            $destinationPath = 'logo/';
            $profileLogo = date('YmdHis') . "." . $logo->getClientOriginalExtension();
            $logo->move($destinationPath, $profileLogo);
            $input['logo'] = "$profileLogo";
        }

        Product::create($input);

        return redirect()->route('products.index')
                        ->with('success','Product created successfully.');
    }
    public function show(Product $product)
    {
        return view('products.show',compact('product'));
    }
    public function edit(Product $product)
    {
        return view('products.edit',compact('product'));
    }
    public function update(Request $request, Product $product)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
            'color' => 'required'
        ]);

        $input = $request->all();

        if ($image = $request->file('image')) {
            $destinationPath = 'image/';
            $profileImage = date('YmdHis') . "." . $image->getClientOriginalExtension();
            $image->move($destinationPath, $profileImage);
            $input['image'] = "$profileImage";
        }else{
            unset($input['image']);
        }

        if ($logo = $request->file('logo')) {
            $destinationPath = 'logo/';
            $profileLogo = date('YmdHis') . "." . $logo->getClientOriginalExtension();
            $logo->move($destinationPath, $profileLogo);
            $input['logo'] = "$profileLogo";
        }else{
            unset($input['logo']);
        }

        $product->update($input);

        return redirect()->route('products.index')
                        ->with('success','Product updated successfully');
    }
    public function destroy(Product $product)
    {
        $product->delete();

        return redirect()->route('products.index')
                        ->with('success','Product deleted successfully');
    }

    function indextwo(){
        //return DB::select("select * from  products");
       //DB::table('products')->orderBy('id','desc')->first();
       return Product::orderBy('id', 'DESC')->first();
    }

}

下面是Product.php as模型

class Product extends Model
{
    use HasFactory;

    protected $fillable = [
        'name', 'detail', 'image','color','logo'
    ];
}

这是index.blade.php

@extends('products.layout')

我已经通过 Auth::id()做到了这一点。
