Calling a DRF View from another View
I have a User Model Viewset that adds users to my Django Rest Framework application (VueJS -> DRF -> PostGres). I have another ModelViewSet for an activity log that has entries when users get credit for doing training, etc. I ran into an issue where I realized that a user that has done nothing, skews the metrics. To combat this, I just want to insert an Activity into the ActivityLog upon user creation. How can I call a ModelViewSet to post a new activity from the the new user post? I read several questions that seemed similar but I am not understanding well enough to translate to my issue. I just want to take the ID created from the new user creation and pass that with some data to the ActivityLogViewset. If I override perform_create() in the UserViewset, how would I call and pass the data to the other endpoint? Thanks. BCBB -

Serving static HTML etc and Django from root '/' using nginx
I have nginx set up to successfully serve a Django website. I'd like to have it also serve a directory of HTML files, images, etc. If a URL doesn't match a file in there, the request should go to Django.

How do I get the client IP address of a websocket connection in Django Channels?
I need to get the client IP address of a websocket connection for some extra functionality I would like to implement. I have an existing deployed Django server running an Nginx-Gunicorn-Uvicorn Worker-Redis configuration. As one might expect, during development, whilst running a local server, everything works as expected. However, when deployed, I receive the error NoneType object is not subscriptable when attempting to access the client IP address of the websocket via self.scope["client"][0]. Here are the configurations and code: NGINX Config: upstream uvicorn { server unix:/run/gunicorn.sock; } server { listen 80; server_name <ip address> <hostname>; location = /favicon.ico { access_log off; log_not_found off; } location / { include proxy_params; proxy_set_header Connection ""; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://uvicorn; proxy_headers_hash_max_size 512; proxy_headers_hash_bucket_size 128; } location /ws/ { proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "Upgrade"; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_redirect off; proxy_pass http://uvicorn; } location /static/ { root /var/www/serverfiles/; autoindex off; } location /media { alias /mnt/apps; } } Gunicorn Config: NOTE: ExecStart has been formatted for readability, it is one line in the actual config [Unit] Description=gunicorn daemon Requires=gunicorn.socket After=network.target [Service] User=django Group=www-data WorkingDirectory=/srv/server Environment=DJANGO_SECRET_KEY= Environment=GITEA_SECRET_KEY= Environment=MSSQL_DATABASE_PASSWORD= ExecStart=/bin/bash -c " source venv/bin/activate; exec /srv/server/venv/bin/gunicorn --workers 3 --bind unix:/run/gunicorn.sock … -

Django update_or_create defaults with a query object
I'm using Django 3.2 and I'm trying to call update_or_create like in the snippet below: from django.db import models result = model.objects.update_or_create( field1="value1", field2="value2", defaults={ "field3": "value3", "field4": ~models.Q(field3="value3"), }, ) field4 is a boolean. The problem is the returning value in field4 after the method is called isn't a boolean, but a query object: result[0].field4 <Q: (NOT (AND: ('field3', 'value3')))> However if I refresh the object, the content is correct: result[0].refresh_from_db() result[0].field4 False I'm sure the field was updated because before I ran the snippet, there was an instance with the same values for field1 and field2 but with the opposite value in field4 (True). My question is: is there a way for update_or_create return a boolean value for field4 without querying the instance again from the DB? I checked StackOverflow before for similar questions, this was the closest one I found but it still doesn't answer my question. -
User Registration alsongside simple-JWT with DRF
I am creating a social media type app(twitter clone). I was using allauth for signup and signin which was working perfectly with endpoints /accounts/login and accounts/signup with their default view. But now I was implementing simple-JWT for authentication. I was following this blog post. The guy is using dj-rest-auth with JWT. Login and logout are mounted with endpoints /dj-rest-auth/login/ and dj-rest-auth/logout/ respectively. Now what about the registration? In the blog it is mentioned: Notice that this list includes allauth social accounts; this is actually so that the registration endpoint of dj-rest-auth can work. But I am unable to figure out the endpoint of the same. So I decided to create my own registration url with following codes: views.py class UserRegister(APIView): def post(self,request): serializer = UserSerializer(data = request.data) if serializer.is_valid(): serializer.save() return Response({"User":serializer.data}) return Response({"errors":serializer.errors}) serializers.py class UserSerializer(serializers.Serializer): email = serializers.EmailField(max_length=50, min_length=6) username = serializers.CharField(max_length=50, min_length=6) password = serializers.CharField(max_length=150, write_only=True) class Meta: model = User fields = ['fname','lname','email','username','password'] def validate(self, args): email = args.get('email', None) username = args.get('username', None) if User.objects.filter(email=email).exists(): raise serializers.ValidationError({"email":"email already exists"}) if User.objects.filter(username=username).exists(): raise serializers.ValidationError({"username":"username already exists"}) return super().validate(args) def create(self, validated_data): return User.objects.create_user(**validated_data) But on launching the respective endpoint I am getting a response: { "detail": … -

How do I amend a form template in Django?
Im using a custom/extended ModelMultipleChoiceField and ModelChoiceIterator as per the answer to another question here https://stackoverflow.com/a/73660104/20600906 It works perfectly but Im trying to amend the template used to generate the groups to apply some custom styling - but after poking around everywhere I cant find anything to overwrite. I have gone through all the template files in '\venv\Lib\site-packages\django\forms\templates\django\forms' and cannot find anything relating to the behaviour Im seeing on screen. The 'groups' are wrapped in tags which is fine, but id like to find the file specifying this so I can overwrite with some bootstrap classes. I've traced back through the class inheritance and the first widget specifiying a template is this one: class Select(ChoiceWidget): input_type = "select" template_name = "django/forms/widgets/select.html" option_template_name = "django/forms/widgets/select_option.html" add_id_index = False checked_attribute = {"selected": True} option_inherits_attrs = False Checking these files doesn't help as they don't appear to be the ones in use. Not sure where i'm going wrong? -
Displaying user orders in user's profile Django

Deal with multiple forms from the same Model in Django
I have a template page where I can create multiple jobs at the same time. They all use the same Form, and when I submit the form, I receive POST data on the view like this: <QueryDict: {'csrfmiddlewaretoken': ['(token)'], 'name': ['name1', 'name2', 'name3'], 'min': ['1', '2', '3'], 'max': ['10', '20', '30'], 'color': ['green', 'blue', 'red']}> In the view, when I do form = JobForm(request.POST), I get the following clean data {'name': 'name3', 'min': 3, 'max': 30, 'color': 'red'}. I have seen this solution, but I don't know how many Jobs will be created at the same time so I can't create different prefixes on the view, so I only send the form to the template like this form = JobForm(). How can I check if all the submitted data is valid and create all the objects in a single page submission? -
wget Python package downloads/saves XML without issue, but not text or html files
Have been using this basic code to download and store updated sitemaps from a hosting/crawling service, and it works fine for all the XML files. However, the text and HTML files appear to be in the wrong encoding, but when I force them all to a single encoding (UTF-8) there is no change and the files are still unreadable (screenshots attached). No matter which encoding is used, the TXT and HTML files are unreadable, but the XML files are fine. I'm using Python 3.10, Django 3.0.9, and the latest wget python package available (3.2) on Windows 11. I've also tried using urllib and other packages with the same results. The code: sitemaps = ["https://.../sitemap.xml", "https://.../sitemap_images.xml", "https://.../sitemap_video.xml", "https://.../sitemap_mobile.xml", "https://.../sitemap.html", "https://.../urllist.txt", "https://.../ror.xml"] def download_and_save(url): save_dir = settings.STATICFILES_DIRS[0] filename = url.split("/")[-1] full_path = os.path.join(save_dir, filename) if os.path.exists(full_path): os.remove(full_path) wget.download(url, full_path) for url in sitemaps: download_and_save(url) For all of the XML files, I get this (which is the correct result): For the urllist.txt and sitemap.html files, however, this is the result: I'm not sure why the XML files save fine, but the encoding is messed up for text (.txt) and html files only. -
