Unable to use override_settings class decorator with setUpClass and tearDownClass Django

Converting a gif to webp in pillow saves the first frame only
I'm trying to convert a gif to webp, but it's not animated anymore it just shows the first frame, how to fix that? here's my code: def make_(image): im = Image.open(image) im_io = BytesIO() im.save(im_io, format='WEBP') name = image.name name = name.replace('.gif', '.webp') webp = InMemoryUploadedFile(im_io, 'ImageField', name, 'image/webp',sys.getsizeof(image), None) return webp and also I don't think replacing .gif with .webp in name = name.replace('.gif', '.webp') is the best approach, so if youu have any suggestions to fix that without using os.

Implement logging in Angular application with django framework [closed]

Is it possible to next lookup fields in Django RestFramework?
Suppose I have a model with a ManyToManyField and would like to add or remove entries using the drf. Is there a way to nest these so that the endpoint url looks like mainmodel/{mainmodel_id}/many_to_many_name/{entry_id}? I tried using 'lookup_fields' as class parameter, which didn't work and nesting Viewsets like this: class MainModelAPI(viewsets.GenericViewSet): model = MainModel serializer_class = MainModelSerializer queryset = MainModel.objects.all() lookup_field = 'mainmodel_id' class SubModel(viewsets.GenericViewSet): model = SubModel lookup_field = 'entry_id' ... But both obviously didn't work. I searched the API but didn't find any reference for "nesting viewsets" or "multiple lookup fields / ids". -

Get fields of foreign key in serializer django
I'm 2 weeks into django so this might be dumb! In my django project, I have 3 models, Teacher, Student and a CustomUser. CustomUser has 2 fields first_name and last_name. Student has 3 fields grade, field_of_study and user which is a foreign key to CustomUser. Now inside my StudentSerializer I want to serialize first_name, last_name, grade and field of study. But because the last 2 field are not direct fields of Student, I cannot do that. Anyone know how this should be handled? I also came across this Retrieving a Foreign Key value with django-rest-framework serializers but the answer didn't help really. -

Hyperlinks in Django for loop are linking to the same page
On a user's profile page right now it is displaying the number of people they are following and the usernames of the people they are following. When the user clicks on a username, I quite simply want it to take the user to that user's profile page but right now it is linking back to the same user's profile page, so essentially just reloading the page. I am guessing it is because I am passing in user.username as a keyword argument because when I follow this same format but instead using user.id I don't run into this problem.

Django Channels after sending message, current tab showing 2 messages(sender + receiver) but other tab does not show anything?
I am following this tutorial Channels Tutorial Link My Goal was to make a simple asgi chat server. But It is showing weird behaviour. The message sent from one tab..should print "HI" in current tab..and also "HI" in the tab connected in the same room. but its printing the both "HI" in the current tab, no message is shown in the other tab connected in the same room. my consumers.py is simeple, just from the tutorials file... import json from asgiref.sync import async_to_sync from channels.generic.websocket import WebsocketConsumer class ChatConsumer(WebsocketConsumer): def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_name'] self.room_group_name = 'chat_%s' % self.room_name # Join room group async_to_sync(self.channel_layer.group_add)( self.room_group_name, self.channel_name ) self.accept() def disconnect(self, close_code): # Leave room group async_to_sync(self.channel_layer.group_discard)( self.room_group_name, self.channel_name ) # Receive message from WebSocket def receive(self, text_data): text_data_json = json.loads(text_data) message = text_data_json['message'] # Send message to room group async_to_sync(self.channel_layer.group_send)( self.room_group_name, { 'type': 'chat_message', 'message': message } ) # Receive message from room group def chat_message(self, event): message = event['message'] # Send message to WebSocket self.send(text_data=json.dumps({ 'message': message })) my settings file is configured to receive redis connection in 127.0.0.1. I am using docker redis image just s the tutorial said. ASGI_APPLICATION = 'mysite.asgi.application' CHANNEL_LAYERS = { 'default': { 'BACKEND': … -
How to add a gitignore folder to github actions?
I have a Django Project and created a dev branch. In my .gitignore file I have the "media" folder. My project looks like this: - Django Project/ - app1/ - app2/ - media/ - profile_pics/ - default.jpg - .gitignore In my gitignore I added media. I've been trying to add github actions, so I created this ci.yml name: Testing on: push jobs: build: runs-on: ubuntu-latest strategy: max-parallel: 4 matrix: python-version: [3.6, 3.7, 3.8] steps: - uses: actions/checkout@v2 - name: Set up Python ${{ matrix.python-version }} uses: actions/setup-python@v2 with: python-version: ${{ matrix.python-version }} - name: Install Dependencies run: | python -m pip install --upgrade pip pip install -r requirements.txt - name: Run Tests run: | python manage.py test When I push the repo I received this message from Github Actions: FileNotFoundError: [Errno 2] No such file or directory: '****/media/default.jpg' What is the best way to deal with this? I could use git add media -f but I do not know if then this file would be in my repo and when I merge it with main and deploy it I would have that folder and overwrites the media in deployment.
