EventTicket | django based project , using opencv | QRCode Processing library

I'd like to implement solution to actively notify user upon incoming Apple wallet pass update. I have implemented all the passkit server api and most of the stuff seems to work ok. The only thing is that the incoming notifications are available only "quietly" to the user. This means while the update appears on the lock screen and notification centre, the device is not waking up the screen nor vibration/sound is played and no banner is being shown.

I tried different approaches to update and even while browsing for similar cases I found barely one place mentioning no banners for pass update (yet the problem there seems more complex and with no solution - https://developer.apple.com/forums/thread/65986) stating the banners.

I am able to see two kind of Notification Centre updates

• one for arbitrary field change using changeMessage (with/without optional %@ string):

sample update changes fragment from pass.json (notification banner is then presented in a usual way in Notification Centre, but just silent delivery)

I'm creating a Ticket from my server and passing it into my ios app but I keep getting this error when I try to pass the JSON data into the PKPass model.

Error Domain=PKPassKitErrorDomain Code=1 "The pass cannot be read because it isn’t valid.

In my server it says that the ticket was created successfully and but I still get this error in Xcode. Am I decoding the data wrong? How can I create the PKPass using the JSON Response?

Server Side code:

I am trying to update multiple objects using IDs which i am passing in every objects that need to be updated but can't find any way to do it successfully. Here is my code

models.py

I am writing the code using java 8 but I iterate a List and then find RestaurantOrderBook using category type. and put that List into a Map. it shows this error:

Local variable itemList defined in an enclosing scope must be final or effectively final

I have problem with relation of laravel in this case.

One event has many event dates.

One event date has many tickets.

One ticket has many slots. User will book slot and save in booking table.

How can i get list of event dates have list of tickets and total booking of every ticket ?

In Event model i has :

I'm using Microsoft Entity Framework and .Net Core 2.1 to create a web application.

In one of my controllers, I'm trying to join 3 different sets of data.

Here is how I'm handling filtering the data:

I am working on a project for class and I have to create a socket server and then a bunch of fake clients that request tickets from a queue. I have all that working just fine however, when I read my Ticket object from the Socket stream I only ever get the first object sent.

At the line Console.WriteLine($"ID {paramData.ClientID} got ticket {tick.TicketID} for show {tick.EventName}"); I get my unique client id which is generated during the for loop however, I get the ticket id of 0 every time.

I have a few thoughts but I am just not sure why this is happening. Firstly, the sends the first ticket over the socket and then re-uses that ticket every time but I am not sure why that would happen, because I dequeue one before sending it.

Another thought is I am just doing the threading completely wrong but I don't understand how the same ticket shows up on the different threads.

Here is a screenshot of the executed code with 10 purchase attempts and 5 available tickets

Entire Code:

I am coding in Swift 3.2. I have a class called EventCollectionView that extends UICollectionView. An instance of this class is an 'event' and I would like to initialize it with three UIImages, images that display the event photo, event info, and event tickets.

However, when I try to call super.init() in the custom initializer I get an error message saying 'Must call a designated initializer of the superclass UICollectionView.' I have tried implementing super.init(frame:CGRect) but that doesn't seem to work either.

Below is the first part of my EventCollectionView class.
