I have a webshop built on ASP.NET Boilerplate (Angular frontend and MSSQL database).
The webshop contains items and I want to keep an inventory of these items.
Every time an order is created the inventory is updated. So basically I have a database with Webshops, Items and Orders.
I have repositories and managers for these objects.
All works fine, but the issue occurs when two clients at the same time load the webshop.
Client1 opens webpage:
Webshop1
Item1: "10 items available"
Item2: "8 items available"
Client2 opens webpage at the same time:
Webshop1
Item1: "10 items available"
Item2: "8 items available"
The first one that buys all the available items, should be able to create an order and the second one should get an error.
When an order is created, the backend checks if there are enough items available.
But when the webshop is loaded BEFORE the order of the first client is created, the second client does not know the updated inventory and will be able to create the order as well.
Meaning 20 items of Item1 can be sold!
How do I "sync" the data between the two sessions in the backend? It seems somehow the data is cached in the backend when loading the webshop.
CreateOrder function
public async Task<CreateOrderResponseDto> Create(CreateOrderDto input, long? userId)
{
input.OrderItems.ForEach(async o =>
{
if (!(await _salesItemManager.ReserveStock(o.SalesItemId, o.Quantity)).IsSuccess)
{
throw CodeException.ToAbpValidationException("OrderItem", "OrderItemCreate");
}
});
var salesPage = await _salesPageManager.Get(input.SalesPageId, false);
if (salesPage.GetState() != StatePage.Published)
{
throw CodeException.ToAbpValidationException("Order", "PageNotAvailable");
}
if (salesPage.CommentsRequired.HasValue && salesPage.CommentsRequired.Value)
{
if (string.IsNullOrWhiteSpace(input.Description))
{
throw CodeException.ToAbpValidationException("Order", "CommentsRequired");
}
}
var order = new Order
{
Address = input.Address,
City = input.City,
LastName = input.LastName,
Name = input.Name,
PostalCode = input.PostalCode,
Email = input.Email,
PhoneNumber = input.PhoneNumber,
Description = input.Description,
SalesPage = salesPage
};
try
{
order.Price = await _salesItemManager.GetPriceByOrders(input.OrderItems);
order = await _orderRepository.InsertAsync(order);
input.OrderItems.ForEach(async o =>
{
var orderItem = new OrderItem();
orderItem.SalesItemId = o.SalesItemId;
orderItem.OrderId = order.Id;
orderItem.Quantity = o.Quantity;
await _orderItemRepository.InsertAsync(orderItem);
});
if (input.SelectedSalesPageOptionId.HasValue)

order.SalesOption = await _salesPageManager.GetOption(input.SelectedSalesPageOptionId.Value);
}
}
catch (Exception e)
{
throw CodeException.ToAbpValidationException("OrderItem", "OrderItemCreate");
}
if (userId.HasValue && salesPage.User.Id == userId.Value)
{
var payment = await _paymentManager.CreateManualPayment(order, input.IsPaid);
order.Payment = payment;
return new CreateOrderResponseDto() { IsSuccess = true, PaymentUrl = string.Empty, OrderId = order.Id.ToString() };
}
else
{
var payment = await _paymentManager.CreatePayment(order);
order.Payment = payment;
return new CreateOrderResponseDto() { IsSuccess = true, PaymentUrl = payment.PaymentUrl, OrderId = order.Id.ToString() };
}
}
ReserveStock function
public async Task<GeneralDto> ReserveStock(Guid itemId, int quantity)
{
var salesItem = await _salesItemRepository.GetAsync(itemId);
if (salesItem == null || salesItem.Stock == null || salesItem.ReservedStock == null)
return new GeneralDto() { IsSuccess = false };
if (salesItem.Stock < quantity)
{
return new GeneralDto() { IsSuccess = false };
}
salesItem.Stock -= quantity;
salesItem.ReservedStock += quantity;
try
{
await _salesItemRepository.UpdateAsync(salesItem);
}
catch (Exception e)
{
throw CodeException.ToAbpValidationException("SalesItem", "SalesItemUpdate");
}
return new GeneralDto() { IsSuccess = true };
}
The problem is not that the data is cached.
The problem is that your ReserveStock checks are async tasks that are not awaited by the caller:
input.OrderItems.ForEach(async o =>
{
if (!(await _salesItemManager.ReserveStock(o.SalesItemId, o.Quantity)).IsSuccess)
{
throw CodeException.ToAbpValidationException("OrderItem", "OrderItemCreate");
}
});
Assign your async ReserveStock checks to an array of tasks that is awaited by the caller:
var reserveStockChecks = input.OrderItems.Select(async o =>
{
if (!(await _salesItemManager.ReserveStock(o.SalesItemId, o.Quantity)).IsSuccess)
{
throw CodeException.ToAbpValidationException("OrderItem", "OrderItemCreate");
}
}).ToArray();
await Task.WhenAll(reserveStockChecks);

Is there any way of checking the status of the payment, because I wanna call another action if the payment is confirmed. Like the same as adding a successful url, but for an action. I'm kinda new to this so :/

I added a webhook to https://xxxx.eu.ngrok.io/payment/UpdatePaymentStatus for this action:

Still not working though. I'm not getting any logs(using nLog) and the webhook is failing(in stripe dashboard).
Your code is creating a Checkout Session via the API. This is associated with Stripe's Checkout product. Stripe controls the UI to collect all the payment method details which means you're going to redirect your customer directly to Stripe's hosted page.
Once a customer pays, they will be redirected to your payment page configured in SuccessUrl in your code. You need to write code that detects the customer hitting that URL and map it to the session they were paying.
Additionally, it's possible for a customer to close their browser too before hitting your page. For that reason, Stripe also sends the checkout.session.completed event to your webhook handler. You can write code to handle that event and look at the status of their payment and all relevant information.
Stripe covers all possible fulfillment approaches in their documentation: https://stripe.com/docs/payments/checkout/fulfill-orders
so I'm working on a mute and unmute command and what I want it to do is find if there is a role called "Muted" in the server if there is then give the user that role if there isn't then create the role with the necessary permissions. I've tried messing with bot permissions, role permissions, and hierarchy and it just doesn't do anything. There is no error given to me via Console nor is there an error generated in the text, it just simply seems to do nothing no matter what I try, can anyone see what I'm doing wrong? I created a pre-existing role called "Muted" and even with the role pre-applied it didn't add it. It also doesn't work while trying to remove the role if I manually added it to the user. This is what I've got:

I created code to send campaign immediately by consuming mailchimp api v3.0 using C# console. When i tried in free account everything goes well, but when i upgrade my account in premium i got this problem (only add 2 members).
My scenario:
create audience => success
add member subscriber into audience that i created => success
create campaign with specific template => success
send cehcklist in campaign already created => return is_ready false
send campaign => return Your Campaign is not ready to send
When I try to run my console program using console c# consume mailchimp api I got this error:
Type: http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/
Title: Bad Request
Status: 400
Detail: Your Campaign is not ready to send.
instance: 214b85f4-a288-44e7-b890-35925d8601ac
When I checked campaign into mailchimp website portal, I saw a message like this:
To send, you need at least 1 subscriber in your list.
This means that there is no recipients in my campaign, here is detail screenshot:
Please has anyone ever faced this, too? I really appreciate any suggestions.
Is there any way to resolve that issue before sending campaign? Because when I checked mailchimp portal (based on screenshot shown above), I back into campaign list then open my campaign above the problem automatically resolve, this is my confusing one.
Because mailchimp api v3.0 has limitation only 500 members subscriber on one call, finally I created class to partition my list:
//partition list of members more than 500
public static class Extensions
{
public static List<List<T>> SplitPartition<T>(this IEnumerable<T> collection, int size)
{
var chunks = new List<List<T>>();
var count = 0;
var temp = new List<T>();
foreach (var element in collection)
{
if (count++ == size)
{
chunks.Add(temp);
temp = new List<T>();
count = 1;
}
temp.Add(element);
}
chunks.Add(temp);
return chunks;
}

I have an API that has devices firing data to it at the same time or within a few milliseconds. What I am finding is that the data is getting mixed up. The data is sent every five minutes (on the clock 05, 10, 15 etc.) I have an execution filter that traps the URL data coming in so I always have a real source, then it goes to the endpoint and then onto processing. For example, there will a be random five minute period missing. When I debug step by step with the missing URL from the execution filter it works fine. By that I mean I take the URL and debug, then it inserts.
In summary, I have device id 1 and device id 2.I will get missing intervals even though, I can see the data has hit the execution filter.
I am assuming that the API is not handling these as separate transactions, but somehow mixing them up together, hence the data missing and the serial numbers appearing in the wrong place, such that data from id 1 is appearing in id 2 vice versa etc.

You are using global variables and static method to process your data.
Change your method to non-static.
Each DeviceClass worker must update only its own isolated data then push that off back to controller.

I have trouble after the confirmation shows. When a user answers yes, BOT will ask CheckIn's prompt.
Why does it not go to the OnCompletion event?
Thanks for your help.
You are clearing out the values in the .Confirm
Try something like this:
var form = new FormBuilder<HotelsQuery>()
.Field(destField)
.Message("Looking for hotels in {Destination}...")
.Field(checkInField)
.Message("Check in {CheckIn}...")
.Field(nightsField)
.Message("Nights : {Nights}...")
.Confirm("Is this your selection?\n {*}", state =>
{
if (_HotelsQuery.Destination == string.Empty ||
_HotelsQuery.CheckIn == DateTime.MinValue ||
_HotelsQuery.Nights == 0)
return false;
return true;
}, new List<string>())
.Message("Thanks you ...")
.OnCompletion(processHotelsSearch)
.Build();
