laravel-wallet - Easy work with virtual wallet.

Describe your task The test suite in laravel are always executed inside a database transaction if you're using the LazilyRefreshDatabase trait. After v8.2, all tests that has a wallet transaction are broken

To Reproduce Steps to reproduce the behavior:

1. write an action that has a app(DatabaseServiceInterface::class)->transaction.
2. write a test with LazilyRefreshDatabase trait.

Expected behavior The test will broke with "Bavix\Wallet\Internal\Exceptions\TransactionStartException : Working inside an embedded transaction is not possible", but this transaction was started by the framework itself, not in userland.

Server:

• php version: 8.1
• database: postgres 14
• wallet version 8.2
• cache lock: redis
• cache wallets: redis

After Confirm the Transaction the wallet of user not update

For Example

$user->balance; // 0 $transaction = $user->deposit(100, null, false); $user->balance; // 0

$user->confirm($transaction); $user->balance; // 0 => Not Changed

Can help me please

Describe the bug Whenever am trying to refund an order (Purchase) am getting the error below:

Bavix\Wallet\Internal\Exceptions\TransactionFailedException

Transaction failed. Message: SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 2

Am using below to refund a purchase.

$order=Order::find(369);
$ouser = User::without(['role','wallet','lastTransaction','defaultAddress'])->with('wallets')->find($order->user_id);
$walletFull = $ouser->wallets[0];
$walletZero = $ouser->wallets[1];
$fullValue = $order->full_credit_used ?? 0;
$zeroValue = $order->zero_credit_used ?? 0;
$orderWallet = $order->wallet;
if($walletFull->refund($order)) {
    $walletFull->refreshBalance();
    if ($zeroValue > 0) {                
        $walletFull->transferFloat($walletZero, $zeroValue);
        $walletFull->refreshBalance();
        $walletZero->refreshBalance();
        $this->manageLastTransaction($walletZero,$this->order);
    }
    $this->manageLastTransaction($walletFull,$this->order,$fullValue);
}

Furthermore, a transfer is also giving the same error, i.e, "1136 Column count doesn't match value count at row 2", Transfer logic is stated below

$metaDeposit =  [
          'description' => 'Refund from Order #'.$this->order->order_number,
          'credit_type' => 'Refunded credits',
          'expire_on'   => Carbon::now()->addYear()
      ];
  $metaWithdraw =  [
          'description' => 'Refund for Order #'.$this->order->order_number,
      ];
  $transferMeta = new Extra(
      deposit: $metaDeposit,
      withdraw: new Option(meta: $metaWithdraw)
  );
  $orderWallet->transfer($walletFull, $fullValue, $transferMeta);

Describe the bug Already handling subscriptions with Laravel Cashier, so as per Laravel Cashier my User Model contains Cahier's Billable trait

use Laravel\Cashier\Billable; 
class User extends Authenticatable
{
   use Billable;
    ....
    ....
}

Now, need to use Wallet's Purchases feature So Changed my User model to this

use Laravel\Cashier\Billable;
use Bavix\Wallet\Traits\HasWallet;
use Bavix\Wallet\Interfaces\Wallet;
use Bavix\Wallet\Traits\CanPay;
use Bavix\Wallet\Interfaces\Customer;
class User extends \TCG\Voyager\Models\User implements Customer
{
    use Billable, HasApiTokens, HasFactory, Notifiable, SoftDeletes, HasWallet;
    use CanPay;
    .......
    .....

But now I am getting below error and even unable to serve. **PHP Fatal error: Trait method Bavix\Wallet\Traits\CanPay::pay has not been applied as App\Models\User::pay, because of collision with Laravel\Cashier\Billable::pay in /var/www/html/better_cloud/app/Models/User.php on line 20

Symfony\Component\ErrorHandler\Error\FatalError

Trait method Bavix\Wallet\Traits\CanPay::pay has not been applied as App\Models\User::pay, because of collision with Laravel\Cashier\Billable::pay**

After upgrading to 6.2.0, the system stopped working completely yet it was displaying zero errors.

After spending almost 5 hours trying to investigate the issue, it turned out that the update caused laravel service container itself to fall into a recursion loop when trying to fetch WalletService::class and Storable::class as it wasn't able to find their aliases in the registered alias list.

Is your feature request related to a problem? Please describe.

Recently, I got almost 100 concurrent requests to debit balance from one wallet via api, and I got a redis exception "could not acquire lock"

Describe the solution you'd like

Read data directly from database when could not acquire lock (and update the state in redis in the next request)

Describe alternatives you've considered

Tried other cache drivers, but the only centralized is redis, array driver for example would give two different results if you access balance in a http container vs a container for queues for example.

P.S: I would put a warning about that non centralized cache drivers in the docs.

Hi.

In the last week when try register depositFloat has next error:

I send an Wallet model

I debug directly but "($this instanceof WalletModel ? $this->holder : $this)" return null, when make inverse "($this instanceof WalletModel ? $this : $this->holder)" works fine and register deposit, how do to work fine??

This is my code: Verify hasWallet and it's correct, then save $wallet and try to make depositFloat

Model Customer has Wallet and HasWallets to have multiple wallets and user WalletFloat

Hi)) I do this: 1.

    public function index(User $user)
    {
        if(is_null($user->getWallet('refill'))){
            $user->createWallet([
                'name' => ucfirst('refill') . 'Wallet',
                'slug' => 'refill',
            ]);
        }
        //$user->fresh();
        //$user->wallet->fresh();

        dd($user->getWallet('refill'));
    }

2. i have error

What am I doing wrong? Thank.

I'm using version 4.1.4

The balance cant't be auto refreshed after user paid, like user has balance of 10, and buy a product(price 10), after paid , this user still has 10. This situation not happend all the time, i don't know when it will happens, so i add

$wallet->refreshBalance();

after user paid.

It just getting better, but still happens, i'm using

• laravel 5.5

• php 7.2

It is very dangerous to our system, we have millions cash flow to handle per month.

When I execute: php artisan wallet:refresh

I get this error:

Illuminate\Database\QueryException : SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'balance' in field list is ambiguous (SQL: updatewalletsleft join (selectwallet_id, sum(amount) balance fromtransactionswhereconfirmed= 1 group bywallet_id) asbonwallets.id=b.wallet_idsetbalance= b.balance)

Don't know if there is a relation, but I also have this error for refunds:

Call to a member function morphMany() on null

Everything else works perfectly (deposit,withdraw,pay,balance)

Any idea?

version 4.1 - laravel 5.8

Hi

I tried to deposit balance to a user wallet inside a Nova Action

but the balance of the wallet is not updating ... I'm not sure if it depends to Locking mecansim or queue of laravel nova actions

but the balance is not updating

any suggestion ?

Describe your task A clear and concise description of your task. I am using this code to specify my User primary key to use another column

public $incrementing = false;
protected $primaryKey = 'code';

I cannot seem to find how to specify which user column to use when creating a wallet. It defaults to my 'code' column which allows string. I want to use the users.id when creating wallet.

Server:

• php version: 8.0
• database: [e.g mysql 8.0]
• wallet version [e.g. 8.2]

Starting from version 9.0, the package wrote the value "Wallet" in the from/to type header and used it in queries, which reduced performance. In the current PR, I want to get away from unnecessary data. The columns themselves will be removed in version 11.x

Updates the requirements on vimeo/psalm to permit the latest version.

Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

In 9.x, you can use the wallet association with the uuid model. I would like to add the ability to dynamically generate a key and asynchronously save transactions. This can give a good performance boost.

There was a problem in the compatibility of contracts. The LTS version is not allowed to change the contract of these methods. If I don’t come up with a compatible API, then the feature will leave before the release of the next version.

At the moment, the development of this functionality is frozen. I'm not clear who needs this functionality.

The functionality of currencies for goods is necessary for currency wallets. A product can be sold in dollars and there is a need to buy it with a euro wallet. Prior to this functionality, the developer had to check the correctness of the payment himself. I was often written that the purchase does not take into account the currency and the goods are bought one to one. For example, if the goods cost one hundred yuan, and the dollar purse, the owner of the wallet will pay one hundred dollars.

Everything would be fine, but this approach has its drawbacks - the return of goods. When returning an item, we must refund the cost, but important data is lost when converting currencies. Perhaps this problem will prevent me from releasing this functionality.

Now I am architecturally working on all possible options and I think that there is a need to use meta-data for the purchase. You pay with your wallet and we supplement the meta-data with the exchange rate, cost, currency and other data. The disadvantage of this approach is the limitation in the possibilities of meta-information.
