Laravel 12 CRUD Tutorial Step-by-Step (2025 Guide)

Step 1: Laravel 12 प्रोजेक्ट बनाएँ
composer create-project laravel/laravel crud_app
cd crud_app

.env में MySQL credentials सेट करें:

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=crud_app

DB_USERNAME=your_username

DB_PASSWORD=your_password

Step 2: Model, Migration, Controller और Validation बनाएँ

php artisan make:model Product -mcr --requests

• -m → Migration बनाएँ

• -cr → Controller resource बनाएँ

• --requests → Form Request validation classes बनाएँ

Step 3: Migration फाइल अपडेट करें

database/migrations/…_create_products_table.php को निम्न कोड से ओवरराइट करें:

public function up(): void {
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('code')->unique();
        $table->string('name');
        $table->integer('quantity');
        $table->decimal('price', 8, 2);
        $table->text('description')->nullable();
        $table->timestamps();
    });
}

माइग्रेट करें:

php artisan migrate

Step 4: routes/web.php में Resource Route जोड़ें

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\ProductController;

Route::resource('products', ProductController::class);

Step 5: Model में $fillable सेट करें

app/Models/Product.php फ़ाइल खोलें और लिखें:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Product extends Model {
    protected $fillable = ['code', 'name', 'quantity', 'price', 'description'];
}

Step 6: Controller Methods को लिखें (app/Http/Controllers/ProductController.php)

namespace App\Http\Controllers;

use App\Models\Product;
use App\Http\Requests\StoreProductRequest;
use App\Http\Requests\UpdateProductRequest;
use Illuminate\View\View;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index(): View
    {
        $products = Product::latest()->paginate(5);
        return view('products.index', compact('products'));
    }

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

    public function store(StoreProductRequest $request)
    {
        Product::create($request->validated());
        return redirect()->route('products.index')
            ->with('success', 'Product created successfully.');
    }

    public function show(Product $product): View
    {
        return view('products.show', compact('product'));
    }

    public function edit(Product $product): View
    {
        return view('products.edit', compact('product'));
    }

    public function update(UpdateProductRequest $request, Product $product)
    {
        $product->update($request->validated());
        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.');
    }
}

Step 7: Blade views बनाएँ (Bootstrap 5 के साथ)

• resources/views/products/index.blade.php

• resources/views/products/create.blade.php

• resources/views/products/edit.blade.php

• resources/views/products/show.blade.php

Views में डेटा दिखाने और CRUD actions के लिए Bootstrap table और forms बनाएं। Validation errors दिखाने के लिए:

To display validation errors, use the following code:

@if ($errors->any())
    @foreach ($errors->all() as $error)
        {{ $error }}
    @endforeach
@endif

Step 8: Development सर्वर चलाएँ

php artisan serve

अब browser में http://127.0.0.1:8000/products खोलें — CRUD operations पहले से working होंगे: Create, Read, Update, Delete सभी संभव हैं।
