Django-Rest-Framework: Login Serializer Error
I am trying to implement the Login system myself, instead of relying on a third-party application. When I try to login, I get a 400 Bad Request Error saying, user with this email already exists, instead of the data, I want it to return. Login Serializer class UserLoginSerializer(serializers.ModelSerializer): class Meta: model = UserProfile fields = ("email", "password") extra_kwargs = {"password": {"write_only":True}} def validate(self, data): email = data["email"] password = data["password"] user = UserProfile.objects.get(email = email) if user: if not user.check_password(data["password"]): raise serializers.ValidationError("Incoreect Password") return data raise serializers.ValidationError("User Not Found") The LoginAPIView class UserLoginAPIView(APIView): def post(self, request): user = UserLoginSerializer(data = request.data) if user.is_valid(): return Response(user.data, status = status.HTTP_200_OK) return Response(user.errors, status = status.HTTP_400_BAD_REQUEST) -

Django Horizontal Scroll on Top of Changelist
I have the same problem as depicted here by mozman2: "In my Django changelist there are lots of columns that means there is a scrollbar at the bottom of the list. Is it possible to get a scrollbar to appear at the top so I don't need to scroll down" The solution from the given link seemed to help mozman2. However, I cannot reproduce it. Hence I tried copy-pasting the code from https://github.com/avianey/jqDoubleScroll#readme In particular, I copied this file from the repository to MyApp/static/admin/js/ jquery.doubleScroll.js The file looks like this: /* * @name DoubleScroll * @desc displays scroll bar on top and on the bottom of the div * @requires jQuery * * @author Pawel Suwala - http://suwala.eu/ * @author Antoine Vianey - http://www.astek.fr/ * @version 0.5 (11-11-2015) * * Dual licensed under the MIT and GPL licenses: * http://www.opensource.org/licenses/mit-license.php * http://www.gnu.org/licenses/gpl.html * * Usage: * https://github.com/avianey/jqDoubleScroll */ (function( $ ) { jQuery.fn.doubleScroll = function(userOptions) { // Default options var options = { contentElement: undefined, // Widest element, if not specified first child element will be used scrollCss: { 'overflow-x': 'auto', 'overflow-y': 'hidden', 'height': '20px' }, contentCss: { 'overflow-x': 'auto', 'overflow-y': 'hidden' }, onlyIfScroll: true, // top scrollbar is not … -
How to estabalish ManyToMany relationship on instantiation of object through generic CreateView?
So I have two models. Deck and Card. When the user creates card it should be tied to a deck, in a ManyToMany relationship.

Not able to serialize a model object in django signals
I have a Task model. After saving the task I want to send a FCM to a device. So I decided to use django signals. Here's the code for it: The model: class Task(models.Model): id = models.AutoField(primary_key=True) issuer = models.ForeignKey(EndUser, on_delete=models.CASCADE, related_name='history') assignee = models.ForeignKey(Mechanic, on_delete=models.CASCADE, related_name='history') vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE, related_name='history') service = models.ForeignKey(Service, on_delete=models.CASCADE) status = models.CharField('Task Status', choices=TASK_STATUS, default=TASK_STATUS[0][0], max_length=64) payment_status = models.CharField('Payment Status', choices=PAYMENT_STATUS, default=PAYMENT_STATUS[0][0], max_length=64) def __str__(self): return "{}-{}-{}".format(self.service, self.issuer, self.assignee) post_save.connect(send_mechanic_notification, sender=Task) The signal function: def send_mechanic_notification(sender, instance, created, **kwargs): if created: instance.assignee.device.send_message( title='New Task Available!', body='Hey!! A new task is available for you', data={ "event": "new_task", "data": instance } ) Now, obviously this won't work because instance is a model object and needs to be serialized. So I tried using a serializer that I have defined. But this was causing circular dependency. I don't want to user model_to_dict because it doesn't serialize the nested fields, and serializing the nested fields is a requirement. How can I solve this problem? -

CeleryD seems to ignore concurrency arguemtn
I've recently upgraded my Django project to Celery 4.4.6 and things aren't going well. My current number one problem is the concurrency of tasks. Because the tasks lock database tables and some are very memory intensive, there's no chance to run eight tasks at the same time. However, that is what celery is set on doing. Previously I was able to run just two tasks at the same time. The worker is daemonised and only one worker is live (one node). I set the concurrency to two. Here's my /etc/default/celeryd: # most people will only start one node: CELERYD_NODES="worker1" # but you can also start multiple and configure settings # for each in CELERYD_OPTS #CELERYD_NODES="worker1 worker2 worker3" # alternatively, you can specify the number of nodes to start: #CELERYD_NODES=3 # Absolute or relative path to the 'celery' command: CELERY_BIN="/home/ubuntu/dev/bin/python -m celery" #CELERY_BIN="/virtualenvs/def/bin/celery" # App instance to use # comment out this line if you don't use an app CELERY_APP="match2" # or fully qualified: #CELERY_APP="proj.tasks:app" # Where to chdir at start. export DJANGO_SETTINGS_MODULE="match2.settings" CELERYD_CHDIR="/home/ubuntu/dev/match2/match2" # Extra command-line arguments to the worker CELERYD_OPTS="--concurrency=2" # Configure node-specific settings by appending node name to arguments: #CELERYD_OPTS="--time-limit=300 -c 8 -c:worker2 4 -c:worker3 2 -Ofair:worker1" # … -

Django Form- Password Validation
I am new to Django just started learning it yesterday. I am trying to create a register form. I know there is inbuilt django register system. But i am trying to it myself.

It does not past form.is_valid() statement. I know this may be a stupid. But just can't find a way to do this. -
How to test which EMAIL credentials were used in tests
I am building an application that sends email through multiple email servers. To achieve this, I created my own settings that allow for multiple email server configurations.

Is there a way to test which credentials were used when testing email sending? -
Django channels, time a message in a websocket
I want to implement a WebSocket which execute a queryset every 120 seconds and returns a response in according to some logic (already exsits) class CarConsumer(JsonWebsocketConsumer): def connect(self): # Manually adding a user for now, later from the url route. self.user_name = '1' self.user_group_name = 'user_%s' % self.user_name self.group = [self.user_group_name, self.channel_name] # Join user group async_to_sync(self.channel_layer.group_add)( self.group[0], self.group[1] ) # TODO: Once working, add Auth # accept connection self.accept() def car(self): result = self.check_events() # Get updated car status self.channel_layer.send( self.farm_group_name, # send result to group {'type': 'check_events', 'message': result } ) def check_events(self): Car.objects.filter() # rest of logic cut dows due to length. So, this code connects when using: const ws = new WebSocket("ws://127.0.0.1:8000/ws/car_online/connect/"); a connection is established, but I can't seem to be able to send a proper message, and other then that, I want the check_events method (the logic) to run every 120 seconds, how can I implement this behavior? The result of the check events method is always a dictionary if it changes something. -
