How to setup permissions to graphql relay queries in Django Graphql that uses JWT authentication
This is a recent problem I encountered in Django I setup a django backend server that serves a graphql api and I used Django Graphql JWT that offers auth functionnality the documentation is here the package offers decorators that can be setup with resolvers and it works perfectly with that, the issue occurs when I try to setup a relay query and would like to authorize that to logged users. Since the syntax to use relay in django excludes the use of a resolver method and therefore really don't know how to setup the authorization. Thanks in advance. -

Intergrating Firebase with Django Rest Framework

I see tutorials using Django Rest Framework and I have been able to get that work but it uses SQLite3 and not Firebase. How can i implement Firebase into Django Rest Framework? -
An alternative to Chrome Dev Mobile Emulator?
I've known for a while now that the chrome mobile emulator can't get 100% accuracy, but it's driving me particularly nuts for a Django website I've been putting together. I know Safari has the option of using a Web Inspector on your phone by connecting to your laptop, but from what I've seen, that's only for Macs (unless I'm wrong, correct me if I am), and I do not have a Mac. Is there any alternative that allows me to get at least a closer percent of accuracy for mobile screens? Here are a few screenshots to show the problem. iPhone vs Chrome Dev Tools -

Threads can only be started once in Django channels
I created a simple Django Channels consumer that should connects to an external source, retrieve data and send it to the client. So, the user opens the page > the consumer connects to the external service and gets the data > the data is sent to the websocket. Here is my code: import json from channels.generic.websocket import WebsocketConsumer, AsyncConsumer, AsyncJsonWebsocketConsumer from binance.client import Client import json from binance.websockets import BinanceSocketManager import time import asyncio client = Client('', '') trades = client.get_recent_trades(symbol='BNBBTC') bm = BinanceSocketManager(client) class EchoConsumer(AsyncJsonWebsocketConsumer): async def connect(self): await self.accept() await self.send_json('test') bm.start_trade_socket('BNBBTC', self.process_message) bm.start() def process_message(self, message): JSON1 = json.dumps(message) JSON2 = json.loads(JSON1) #define variables Rate = JSON2['p'] Quantity = JSON2['q'] Symbol = JSON2['s'] Order = JSON2['m'] asyncio.create_task(self.send_json(Rate)) print(Rate) This code works when i open one page; if i try to open a new window with a new account, though, it will throw the following error: File "C:\Users\User\Desktop\Heroku\github\master\Binance\consumers.py", line 54, in connect bm.start() File "C:\Users\Davide\lib\threading.py", line 843, in start raise RuntimeError("threads can only be started once") threads can only be started once I'm new to Channels, so this is a noob question, but how can i fix this problem?

Django Rest Framework is serializing an object two different ways using the same serializer
When using a DRF ViewSet and an APIView, I get two different results for serialization of a DurationField. At the first endpoint host/app/items, which corresponds to the viewset Items and lists all of the created items, I get this response: [ { "id": 2, "duration": "604800.0", ... } ... ] The response from host/app/user_data includes the items corresponding to the item instances which have a relation to the profile: { ... "items": [ { "item": { "id": 2, "duration": "P7DT00H00M00S", ... } ... } ] } But the duration is in the ISO 8601 duration format. This was very perplexing, because the endpoints use the same serializer. I confirmed this by forcing the serializing with duration = serializers.DurationField() in ItemSerializer. I want the same format, in seconds. What can I do? These are issues I found while researching this issue: https://github.com/encode/django-rest-framework/issues/4430 https://github.com/encode/django-rest-framework/issues/4665 Urls: router = routers.DefaultRouter() router.register(r'items', views.Items) urlpatterns = [ path('', include(router.urls)), path('user_data', views.UserData.as_view(), name='user_data'), ... ] Views: class Items(viewsets.ModelViewSet): queryset = Item.objects.all() serializer_class = ItemSerializer def get_permissions(self): if self.action in ('list', 'retrieve'): permission_classes = [AllowAny] else: permission_classes = [IsAdminUser] return [permission() for permission in permission_classes] class UserData(APIView): """Get authenticated user's information: data related to models User and Profile""" … -
View Flow and Django Guardian
I am relatively new to django-guardian and django-viewflow , am still trying to wrap my head around things. Recently i have been attempting to implement a workflow system to get approvals on certain documents. As such i have chosen view flow workflow engine. The workflow that i have been tasked on developing is actually pretty simple and linear. However , at every check point , there must be a different person with a specialized role to verify the documents. There is 4 roles, 1 the preparer , 2 the verifier , 3 the treasury and 4 the Director. As i can't have someone verifying for the Director himself , there is a need for a role based user control. As such , i have adopted django guardian to do this job. Here is some of my code to demonstrate how i did it : Flows.py class Pipeline(Flow): process_class = PaymentVoucherProcess lock_impl = lock.select_for_update_lock #process starts here start = flow.Start( CreateProcessView, fields=["paymentVoucher"], task_title="Processing New Voucher" ).Permission("can_start_voucher", auto_create=True ).Next(this.documents) #preparer will upload supporting documents documents = flow.View( UploadView, task_title="Receiving Supporting Documents" ).Permission("preparer", auto_create=True ).Next(this.preparer) #i wont go in detail as it isn't relevant Models.py this is where i defined my permissions , … -
