<?php

namespace App\Http\Controllers;

use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index()
    {
        // 获取所有产品
        $products = Product::all();

        return view('products.index', ['products' => $products]);
    }

    public function create()
    {
        return view('products.create');
    }

    public function store(Request $request)
    {
        // 创建并保存新产品
        $product = Product::create($request->all());

        return redirect('/products');
    }

    // ... 省略其他方法
}
