Laravel is a PHP framework that has become quite popular in recent years. One of the reasons for its popularity is that it follows industry best practices, including the use of Model-View-Controller (MVC) architecture, which separates business logic, presentation, and data handling. In this blog post, we will be creating a simple example of CRUD (Create, Read, Update, Delete) operations for a Product model using Laravel’s industry best practices.
We will be using Laravel 10 for this example. Let’s get started.
Create a new Laravel project using the following command:
composer create-project --prefer-dist laravel/laravel product-crud-example
In Laravel, a model represents a database table. We will create a Product model to represent our products table.
php artisan make:model Product -mcr
This command will create a Product model with the following files:
app/Models/Product.phpdatabase/migrations/2023_03_25_000000_create_products_table.phpapp/Http/Controllers/ProductController.phproutes/web.phpThe -mcr option will also create a migration, controller, and resourceful routes for the Product model.
Open database/migrations/2023_03_25_000000_create_products_table.php file and define the schema for the products table.
id();
$table->string('name');
$table->text('description');
$table->decimal('price', 8, 2);
$table->timestamps();
});
}
public function down(): void
{
Schema::dropIfExists('products');
}
}
This schema defines the id, name, description, price, and timestamps columns for the products table.
Open the app/Models/Product.php file and define the Product model.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Product extends Model
{
use HasFactory;
protected $fillable = [
'name',
'description',
'price',
];
}
The Product model extends the base Model class and uses the HasFactory trait. The $fillable property defines which model attributes are mass assignable.
Create a new StoreProductRequest class using the following command:
php artisan make:request StoreProductRequest
Open the app/Http/Requests/StoreProductRequest.php file and define the StoreProductRequest.
'required|string|max:255',
'description' => 'required|string',
'price' => 'required|numeric|min:0',
];
}
}
Create a new UpdateProductRequest class using the following command:
php artisan make:request UpdateProductRequest
Open the app/Http/Requests/UpdateProductRequest.php file and define the UpdateProductRequest.
'required|string|max:255',
'description' => 'required|string',
'price' => 'required|numeric|min:0',
];
}
}
Open the app/Http/Controllers/ProductController.php file and define the ProductController.
validated());
return redirect()->route('products.index');
}
/**
* Show the form for editing the specified resource.
*
* @param Product $product
* @return View
*/
public function edit(Product $product): View
{
return view('products.edit', compact('product'));
}
/**
* Update the specified resource in storage.
*
* @param UpdateProductRequest $request
* @param Product $product
* @return RedirectResponse
*/
public function update(UpdateProductRequest $request, Product $product): RedirectResponse
{
$product->update($request->validated());
return redirect()->route('products.index');
}
/**
* Remove the specified resource from storage.
*
* @param Product $product
* @return RedirectResponse
*/
public function destroy(Product $product): RedirectResponse
{
$product->delete();
return redirect()->route('products.index');
}
}
Create the `products` directory inside the `resources/views` directory. Create the following views inside the `products` directory:
create files:
– index.blade.php
– create.blade.php
– edit.blade.php
index.blade.php
@extends('layouts.app')
@section('content')
<h1>Products</h1>
<p>
<a href="{{ route('products.create') }}">Create Product</a>
</p>
<table>
<thead>
<tr>
<th>Name</th>
<th>Description</th>
<th>Price</th>
<th>Actions</th>
</tr>
</thead>
<tbody>
@foreach ($products as $product)
<tr>
<td>{{ $product->name }}</td>
<td>{{ $product->description }}</td>
<td>{{ $product->price }}</td>
<td>
<a href="{{ route('products.edit', $product) }}">Edit</a>
@csrf
@method('DELETE')
<button type="submit">Delete</button>
</td>
</tr>
@endforeach
</tbody>
</table>
@endsection
The index.blade.php view displays a table with all the products in the database. It also provides links to create a new product and edit or delete existing products.
create.blade.php
@extends('layouts.app')
@section('content')
<h1>Create Product</h1>
@csrf
<div>
<label for="name">Name:</label>
</div>
<div>
<label for="description">Description:</label>
<textarea name="description" id="description">{{ old('description') }}</textarea>
</div>
<div>
<label for="price">Price:</label>
</div>
<button type="submit">Create</button>
@endsection
The create.blade.php view displays a form to create a new product. It includes fields for the name, description, and price of the product.
edit.blade.php
@extends('layouts.app')
@section('content')
<h1>Edit Product</h1>
@csrf
@method('PATCH')
<div>
<label for="name">Name:</label>
name) }}" required>
</div>
<div>
<label for="description">Description:</label>
<textarea name="description" id="description">{{ old('description', $product->description) }}</textarea>
</div>
<div>
<label for="price">Price:</label>
price) }}" step="0.01" required>
</div>
<button type="submit">Update</button>
@endsection
The edit.blade.php view displays a form to edit an existing product. It pre-populates the fields with the current values of the product and updates the product in the database when the form is submitted.
Route::get('/products', [ProductController::class, 'index'])->name('products.index');
Route::get('/products/create', [ProductController::class, 'create'])->name('products.create');
Route::post('/products', [ProductController::class, 'store'])->name('products.store');
Route::get('/products/{product}/edit', [ProductController::class, 'edit'])->name('products.edit');
Route::patch('/products/{product}', [ProductController::class, 'update'])->name('products.update');
Route::delete('/products/{product}', [ProductController::class, 'destroy'])->name('products.destroy');
These routes map the HTTP methods and URIs to the methods defined in the ProductController class.
php artisan serve
you get something like this:
INFO Server running on [http://127.0.0.1:8000].
In this blog post, we have learned how to implement the CRUD operations for a Product model in Laravel. We have followed the industry best practices to create a Request class to validate the input, a Model class to represent the database table, a Controller class to handle the HTTP requests, and views to display and process the input. We have also defined the routes to map the HTTP methods and URIs to the methods in the controller. This is just a basic example, but it can be extended and customized to fit your specific needs.
