Why does Django REST Framework Router break query parameter filtering?
In the Django REST Framework Tutorial quickstart, views are added to the default router: // project/urls.py router = routers.DefaultRouter() router.register(r'users', views.UserViewSet) My project layout is project/ stuffs/ I include the stuffs application in the default router: router.register(r'stuffs', views.StuffViewSet) The stuffs/ endpoint is then nicely listed in the API Root list of endpoints: HTTP 200 OK Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept { "users": "http://localhost:8000/users/", "groups": "http://localhost:8000/groups/", "stuffs": "http://localhost:8000/stuffs/" } A Stuff object has a relationship to a owner model class and to filter for objects belonging to a certain owner, I intend to use a request such as: stuffs/?owner_id=abc In order to do so, and here is where I'm not sure if it is correct, I introduced an urls.py configuration in the stuffs app: // stuffs/urls.py urlpatterns = format_suffix_patterns([ path('stuffs/', stuffs_views.StuffList.as_view()), path('stuffs/<int:pk>/', stuffs_views.StuffDetail.as_view()), re_path(r'^stuffs/(?P<owner_id>.+)$', stuffs_views.StuffsList.as_view()) ]) using the below StuffsList class based view: class StuffList(generics.ListCreateAPIView): serializer_class = StuffSerializer def get_queryset(self): queryset = Stuff.objects.all() owner_id = self.request.query_params.get('owner_id') if owner_id is not None: queryset = queryset.filter(owner__short_id=short_id) return queryset I'm pretty sure this view is correct, because when I remove the View Set from the default router, the query works. However, when the viewset is registered in the default router, when … -

Django:How to add field dynamically?

Django - Suggestions with building a minimal one-to-one chat app (Potentially using Web Sockets)
My next challenge is to build a minimal realtime chat application where my users of my application can send direct one-to-one messages to each other. With this being said, I have researched online in to building realtime chat apps and many of which I have seen refer to building "group" chats through using Django Channels. Secondly, I have also looked in to tutorials which provide guidance on how to build an AJAX refresh based chat app (without Web Sockets) but I thought this approach would be inefficient with the heavy strain on my server this could cause as my user base grows. I am wanting to reach out on here and ask - Is there any existing Django Libraries out there for building efficient one-to-one chat apps (Without WebSockets) or would I be better served using WebSockets? And if I was to use the WebSockets approach with Django-Channels and ASGI, are there any recommended tutorials or chat libraries which I can use to help kickstart the development of my chat app? I'm eager to learn, but I just need a little direction with understanding where my initial starting point and focus should be. As simple as what my vision is, … -
Show and modify local Json file from a web page using python
ive written a script, that stores its configuration in a local json file. The script runs in a continuous loop and loads the configuration at startup. Because i will run my script in a headless machine, i thought on writing a small web app to allow me to view and modify this json file and reload the script if a change is made Also it would be handy to show some stats and maybe the console output logs in the web page I can program in python but im totally new in web development. I did some research and flask looks to be the easiest way My idea is to load the json tree in a web page in a user friendly way, and allow you to modify the 'value' part of each 'key' in the json from a nice edit box or something. I would also need to add key value sub pairs for some given keys Then at the bottom one would have a 'reload' button that would save the updated json file into the file system and reload the script with its new configuration. Im not sure if its best to keep this two separated, one as … -

Django: reducing inventory and change model display format in admin
I'm trying to make a website where users can register an account and sign up for different courses via stripe. I buildt the system with an Order -> OrderItem -> Product (Kurs) model. Thanks to great tutorials I have been able to make most of what I want but I am still a beginner and now I'm having a hard time figuring stuff out. After signing up an account the users can view all courses that have been added to the course model and add them to a basket and procceed to checkout the orders in the basket. When stripe signals the payment_intent_succeeded all the products from that order change billing_status to 'True'. I am able to see all Orders and the OrderItem from the django admin view but now I am missing two features that I can't figure out how to add. 1. To reduce integerField "ledige_plasser" in the Product model (called Kurs in my code) model after each purchase is made. 2. To view the all the orders for a certain Kurs (product) in the django admin in a readable way. Is there any way I can setup the django admin to display all users that have signed … -

Spring boot looks more boiler plate than Django
In Django to create a model we have to just do: class Sample(models.Model): sample = models.CharField(max_length=100) and later to all the operations are very easy Sample(sample="test").save(), Sample.objects.all() etc Where as in spring boot we have to first define an entity and then a repository for that entity and then do all the operations @Entity @Table(name = "sample") public class Sample { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String sample; public Sample() { } public Sample(String sample) { this.sample = sample; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getSample() { return sample; } public void setSample(String name) { this.sample = sample; } @Repository public interface SampleRepository extends JpaRepository<Sample, Long> { } Then @Service public class SampleService { @Autowired private SampleRepository sampleRepository; public List<Sample> findAll() { return (List<Sample>) SampleRepository.findAll(); } } Is there any easy way like Django. Even the time to understand to this level is also a lot -

Migrate native app (android/ios) to react
I have a situation that maybe you can help and would love to hear your opinions. I have an app from a startup with android and iOS version and the backend with Django. Right now is so expensive to maintain because there’s different technologies and I was wondering if to migrate to a multi platform technology as Reactjs (PWA) and maybe use firebase as a service for backend. The app is live now (pinwins) but it’s a MBP that needs corrections and development. Its has been developed by an agencie and for the moment I can count on a junior profile on react. What do you think? Would you keep working in this one or would you migrate to a new technology with more agile development? (In this case what would be the best way?)
