Usage Concepts

Money columns with default Currency

<?php

namespace App;

use Andriichuk\Laracash\Casts\MoneyCast;
use Illuminate\Database\Eloquent\Model;
use Money\Money;

/**
 * Class OrderItem
 *
 * @property Money $price
 * @property Money $discount
 */
class OrderItem extends Model
{
    protected $fillable = ['name', 'price', 'discount'];

    protected $casts = [
        'price' => MoneyCast::class,
        'discount' => MoneyCast::class,
    ];
}

OrderItem::create([
    'name' => 'Order Item',
    'price' => makeMoney(1000),
    'discount' => makeMoney(15),
]);

Currency columns without Money

<?php

namespace App;

use Andriichuk\Laracash\Casts\CurrencyCast;
use Andriichuk\Laracash\Model\HasCurrency;
use Andriichuk\Laracash\Model\HasCurrencyInterface;
use Illuminate\Database\Eloquent\Model;
use Money\Currency;

/**
 * Class Rate
 *
 * @property Currency $currency
 */
class Rate extends Model implements HasCurrencyInterface
{
    use HasCurrency;

    protected $fillable = ['name', 'price', 'currency', 'native_currency'];

    protected $casts = [
        'currency' => CurrencyCast::class,
        'native_currency' => CurrencyCast::class,
    ];
}

Rate::create([
    'name' => 'Rate #1', 
    'price' => 99, 
    'currency' => new Currency('USD'), 
    'native_currency' => 'UAH',
]);

Multiple Money columns refer to one Currency column

use Andriichuk\Laracash\Casts\CurrencyCast;
use Andriichuk\Laracash\Casts\MoneyCast;
use Andriichuk\Laracash\Model\HasCurrency;
use Andriichuk\Laracash\Model\HasMoneyWithCurrency;
use Andriichuk\Laracash\Model\HasMoneyWithCurrencyInterface;
use Illuminate\Database\Eloquent\Model;
use Money\Currency;
use Money\Money;

/**
 * Class Transaction
 *
 * @property Money $payment_amount
 * @property Money $discount
 * @property Currency $currency
 */
class Transaction extends Model implements HasMoneyWithCurrencyInterface
{
    use HasMoneyWithCurrency;
    use HasCurrency;

    protected $fillable = ['name', 'payment_amount', 'discount', 'currency'];

    protected $casts = [
        'payment_amount' => MoneyCast::class,
        'discount' => MoneyCast::class,
        'currency' => CurrencyCast::class,
    ];

    public function getCurrencyColumnFor(string $field): string
    {
        return 'currency';
    }
}

If the currency is in a related model, just return an empty string ('') in getCurrencyColumnFor().

Money to Currencies columns mapping

use Andriichuk\Laracash\Casts\CurrencyCast;
use Andriichuk\Laracash\Casts\MoneyCast;
use Andriichuk\Laracash\Model\HasCurrency;use Andriichuk\Laracash\Model\HasMoneyWithCurrency;
use Andriichuk\Laracash\Model\HasMoneyWithCurrencyInterface;
use Illuminate\Database\Eloquent\Model;
use Money\Currency;
use Money\Money;

/**
 * Class Product
 *
 * @property Money $payment_amount
 * @property Money $discount
 * @property Currency $currency
 */
class Product extends Model implements HasMoneyWithCurrencyInterface 
{
    use HasMoneyWithCurrency;
    use HasCurrency;

    protected $fillable = ['name', 'price', 'currency', 'book_price', 'native_currency'];

    protected $casts = [
        'price' => MoneyCast::class,
        'currency' => CurrencyCast::class,

        'book_price' => MoneyCast::class,
        'native_currency' => CurrencyCast::class
    ];

    public function getCurrencyColumnFor(string $field): string
    {
        return [
            'price' => 'currency',
            'book_price' => 'native_currency',
        ][$field] ?? '';
    }
}

Product::create([
    'price' => \Money\Money::USD(1000),
    'book_price' => Money::UAH(25000),
]);

If you want to use magic accessors (*_as_currency, *_as_decimal) for money fields then you should add HasMoney trait to your Eloquent Model (accessors will be added automatically)

<?php

namespace App;

use Andriichuk\Laracash\Casts\MoneyCast;
use Andriichuk\Laracash\Model\HasMoney;
use Illuminate\Database\Eloquent\Model;
use Money\Money;

/**
 * Class Product
 *
 * @property Money $price
 * @property-read string $price_as_currency
 * @property-read string $price_as_decimal
 */
class Product extends Model
{
    use HasMoney;

    protected $fillable = ['name', 'price'];

    protected $casts = [
        'price' => MoneyCast::class,
    ];
}

Now you can call magic fields

use App\Product;

$product = Product::find(1);

$product->price_as_decimal; // "10.00"
$product->price_as_currency; // "$10.00"

$product->price = 5000;

$product->price_as_decimal; // "50.00"
$product->price_as_currency; // "$50.00"

Display money data in the form input field

Assign model

use App\Product;
use Illuminate\Support\Facades\Route;

Route::view('/', 'productForm', ['product' => Product::find(1)]);

Present money object as a decimal value

<input type="number" name="price" value="{{ formatMoneyAsDecimal($product->price) }}">

{{-- or with magic syntax --}}
<input type="number" name="price" value="{{ $product->price_as_decimal }}">

Parse money from request field

use App\Product;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

Route::post('products/{product}', function (Product $product, Request $request) {
    $product->price = parseMoneyDecimal($request->get('price')); // 55.99 => Money::USD(5599)
});

Using in API resources

Define model resource

use App\Product;
use Illuminate\Http\Resources\Json\JsonResource;

/**
 * Class ProductResource
 *
 * @mixin Product
 */
final class ProductResource extends JsonResource
{
    public function toArray($request): array
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'price' => $this->price,
            'price_as_currency' => $this->price_as_currency, // or formatMoneyAsCurrency($this->price)
        ];
    }
}

Apply resource to the model

use App\Product;
use App\Http\Resources\ProductResource;

Route::get('products/{product}', function (Product $product) {
    return new ProductResource($product);
});

Output

{
  "data": {
    "id": 1,
    "name": "Product name",
    "price": {
      "amount": "1000",
      "currency": "USD"
    },
    "price_as_currency": "$10.00"
  }
}

Model Creation

Using scalar values (int|string)

use App\Product;

Product::create([
    'name' => 'The First Product',
    'price' => 100,
]);

Using Money\Money object:

use App\Product;
use Money\Money;

Product::create([
    'name' => 'The Second Product',
    'price' => Money::USD(100),
]);

Using facade:

use Andriichuk\Laracash\Facades\Laracash;
use App\Product;

Product::create([
    'name' => 'The Third Product',
    'price' => Laracash::factory()->make(100)
]);

Using helper function:

use App\Product;

Product::create([
    'name' => 'The Fourth Product',
    'price' => makeMoney(100)
]);

Bitcoin creation

use Andriichuk\Laracash\Facades\Laracash;
use Money\Money;

// Using Facade
Laracash::factory()->makeBitcoin(1000000000);

// Using helper
makeBitcoin(1000000000);

// Using native library factory call
Money::XBT(1000000000);

Retrieving data

use App\Product;

$product = Product::find(1);

dd($product->price);

Money\Money {#403 ▼
  -amount: "1000"
  -currency: Money\Currency {#404 ▼
    -code: "USD"
  }
}

Operations

Check original library docs for more information

use Andriichuk\Laracash\Facades\Laracash;
use App\Product;

$product = Product::find(1);

$product->price = $product->price->add(Laracash::factory()->make(2000));

$product->save();

API

Creation

Money instance creation using Laracash facade.

*If you do not pass the second argument currency, then it will take from config file

use \Andriichuk\Laracash\Facades\Laracash;

Laracash::factory()->make(1000);
Laracash::factory()->make('10000000000000');

Specify currency

use \Andriichuk\Laracash\Facades\Laracash;
use \Money\Currency;

Laracash::factory()->make(1000, 'USD');
Laracash::factory()->make(1000, new Currency('USD'));

// Or use native method Money::USD(100)

Money\Money {#403 ▼
  -amount: "1000"
  -currency: Money\Currency {#404 ▼
    -code: "USD"
  }
}
