Create Customer Quotes with Products

Next, we will dive deeper into a specific CRM use case: Products and Quotes. In this lesson, we will start creating our simple Products and allow users to create Quotes that later we will turn into a PDF. Here's what our Products and Quotes will look like:

In this lesson, we will do the following:

• Create a Product Model, Database Table, and CRUD
• Create a Quote Model, Database Table, and CRUD
• Create a complex Quote create/edit form with real-time calculations
• Create an action button on the Customer list to create a Quote
• Modify how our Customer actions look like

Creating the Product Model

Our first task is to create a Product table in the database so that we would have something to sell:

Migration

Schema::create('products', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->integer('price');
    $table->timestamps();
});

Next, let's work on the Model:

app/Models/Product.php

use Illuminate\Database\Eloquent\Casts\Attribute;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;
 
class Product extends Model
{
    use HasFactory;
 
    protected $fillable = ['name', 'price'];
 
    protected function price(): Attribute
    {
        return Attribute::make(
            get: static fn($value) => $value / 100,
            set: static fn($value) => $value * 100,
        );
    }
}

Lastly, for our Database setup, we need a seeder:

database/seeders/DatabaseSeeder.php

use App\Models\Product;
 
// ...
 
public function run(): void
{
    // ...
 
    $products = [
        ['name' => 'Product 1', 'price' => 12.99],
        ['name' => 'Product 2', 'price' => 2.99],
        ['name' => 'Product 3', 'price' => 55.99],
        ['name' => 'Product 4', 'price' => 99.99],
        ['name' => 'Product 5', 'price' => 1.99],
        ['name' => 'Product 6', 'price' => 12.99],
        ['name' => 'Product 7', 'price' => 15.99],
        ['name' => 'Product 8', 'price' => 29.99],
        ['name' => 'Product 9', 'price' => 33.99],
        ['name' => 'Product 10', 'price' => 62.99],
        ['name' => 'Product 11', 'price' => 42.99],
        ['name' => 'Product 12', 'price' => 112.99],
        ['name' => 'Product 13', 'price' => 602.99],
        ['name' => 'Product 14', 'price' => 129.99],
        ['name' => 'Product 15', 'price' => 1200.99],
    ];
 
    foreach ($products as $product) {
        Product::create($product);
    }
}

Then running php artisan migrate:fresh --seed will give us a simple set of products to test the system.

Creating Product Resource

Next, we want to manage the products using Filament, so let's create a new resource:

php artisan make:filament-resource Product --generate

This will generate all of our Resource files. This time, we...
