django.db.utils.ProgrammingError: relation does not exist
I developed a Django application deployed on DigitalOcean's Ubuntu server with Postgres db. Everything worked fine, without any problems, but today after adding new model, I'm getting this error: relation "documents_app_document" does not exist although I have this model, where some of my models inherits from Document model. But somehow it was deleted from database, and now I can't add it back to database after migration. How can I add that model as a table again to database ? -

Adding schema name to media path for django-tenant based site
I have a Django class that I use to save my media directory to Azure.

How exactly do django serializers and views work together? And how can I return additional data with my queryset to the frontend?
I'm working with a react front end and a django rest framework backend, and I'm having trouble understanding what happens in between the view and the serializer. I want to return additional metadata that is not part of the queryset to the front end. Here is the flow of my application My frontend calls an endpoint: Server.get("api/books-filtered") This goes to a path in the backend written with django rest framework: path("books-filtered/", Books.BookList.as_view()), and then to class Books(generics.RetrieveAPIView): serializer_class = BookSerializer lookup_field = 'id' lookup_url_kwarg = 'book_id' def get_queryset(self): """Return only queries pertaining to the patient""" return FilterOutSomeBookRelatedQuerySetHere() whose serializer class is: class BookSerializer(SurveySerializer): class Meta: model = Book fields = ['Title','Author','Publisher'] I get this back on the front end: console.log(Server.get("api/books-filtered")) // prints [{Title:"book 1", Author:"author 1", Publisher:"publisher 1"},{Title:"book 2", Author:"author 2", Publisher:"publisher 2"},{Title:"book 3", Author:"author 3", Publisher:"publisher 3"}] What happens between the view and the serializer that causes the data to be formatted like that by the time its sent back to the frontend? How can I modify what gets printed by console.log(Server.get("api/books-filtered")) to include additional metadata? Like console.log(Server.get("api/books-filtered")) // prints [{Title:"book 1", Author:"author 1", Publisher:"publisher 1"},{Title:"book 2", Author:"author 1", Publisher:"publisher 2"},{Title:"book 3", Author:"author 1", Publisher:"publisher 2"}, [3 books, 2 … -
Django app custom clean up for code reload
my Django project has an app which overrides its AppConfig.ready() method. In the ready method, I'm starting a separate multiprocessing.Process to handle consuming from an external message queue, this seems to be causing problems with autoreload on code changes. def infinite_loop(): while True: time.sleep(10) class BrokerConfig(AppConfig): name = 'backend.broker' has_started = False def ready(self): if not os.environ.get("RUN_MAIN"): # Avoid running for reloader return if BrokerConfig.has_started: return BrokerConfig.has_started = True proc = Process(target=infinite_loop) proc.start() For whatever reason, this causes the automatic code reload to break. Seems the reloader is not able to clean up started processes. The reloader prints this and then gets stuck: .../backend/broker/apps.py changed, reloading. I run into exactly the same issue if I start a threading.Thread instead of a multiprocessing.Process. I am looking for some way to add some custom clean up when the reloading is happening, but I can't seem to find a way to do that. Is there some hook or signal you can subscribe to in order to find out if reloading has been triggered? Alternatively, I need to find another solution to subscribing to message queues. I was looking at Django Channels, but it did not look like they had built-in support for RabbitMQ, … -

'Incorrect Padding' error while using google.oauth2 id_token.verify_oauth2_token() in Django
I am trying to verify a user's submitted google authentication JWT from a React frontend to my Django backend. I have my frontend POST a request to the backend with the JWT, and then my backend extracts it from the request and processes it through google's recommend token authentication found here. My problem is that each time I process a JWT received from my frontend through id_token.verify_ouath2_token(), an error about 'incorrect padding' is raised ultimately stemming from the base64 encoding of the token. When testing this manually by copy-pasting the token I have extracted from the POST request, however, it works perfectly fine and does not raise an error. So somewhere in my handling of the post request something goes wrong, but I'm not sure what. I have tried decoding the POST request in utf-8 and ascii, and simply leaving the JWT in the bytes form that I extracted it as. All of these throw the same error, and I'm left pretty confused. Here is my code: views.py def login(request): if request.method == "POST": print(request.body.decode("ascii")) # For decoding. By copy/pasting this output into id_token.verify_oauth2_token instead of the token variable, the function returns successfully try: token = request.body.decode("ascii") # Specify the … -
Assigning Value(s) to ManyToMany Field
I'm trying to assign a value onto a ManyToMany field in the Order class. def assign_order(request, user_id): order_id = request.session.get('order_id') #picking this session from a previous fxn allowing me to call the order.id order = get_object_or_404(Order, id=order_id) employee = Employee.objects.filter(user_id=user_id) #Employee is a profile model leveraging an AbstractUser order.deliverer.set(employee) #using .set() for direct assignment of user(Employee) onto ManyToMany field on "Order" order.status = 'deliverer_assigned' order.save() The problem with this schema is that the fxn will always overwrite my ManyToMany field rather than append a new User(Employee profile) onto it. 1. Is there a better way of accomplishing what I need? i.e. Updating a ManyToMany field outside the admin? 2. How do I prevent the overwrite problem in this scenario? -

django SITE_ID by query
I have a django app. I'm adding a second site. So now I need to set SITE_ID correctly. This is easy enough, except that since it is the primary key id in the Site table, this means the value is dependent on the order in which sites have been added (and, eventually, deleted). That's fragile, without even discussing how developers will sort this if they've done any scratch work in that table. Much better to set it by query. SITE_ID = Site.objects.get(name='my_site_name').id But the settings_myapp.py file, which sets WSGI_APPLICATION, is pretty much the only one that might know which app I'm running. I could try modifying settings in that site-specific settings file, but importing settings at that point leads to an error that SECRET_KEY is not yet defined. Is there a robust way to do this? -

What is the easiest way to load JSON data from API to Django Template with minimum JavaScript usage
I am looking for the easiest way to load JSON data from API in Django Template without page refresh. I really like to stick with the Django style of Coding and I am new to JavaScript. I have several views in my project that read data from JSON APIs and I am reading them in my views.py and passing the results to templates. Currently, I am refreshing my pages every 10 seconds to show the latest data. But I need to do this without the complete page refresh. Is there any way to achieve this without re-writing everything in JavaScript? If not what is the closest alternative solution? I have read several answers about Ajax calls and also this detailed answer about django-channels. But all of them involve a lot of JavaScript. I would appreciate any suggestion that will make my work easier than these. Below is my example view. (Please note that this is only an example and I have several similar views in my project. That is also the reason why I want to avoid writing custom JavaScript for each view) # views.py import requests class MyView(TemplateView): def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['data'] = requests.get('https://url_to_my_json').json() return context … -

When I visit http://localhost:8000/ I get 500 - Internal Server Error. When I visit http://localhost:80/, however, I get Welcome to nginx! web page. To configure nginx and Gunicorn, I followed this guide, skipping steps 5 to 7 (inclusive). I have to note that in my /etc/nginx the sites-available and sites-enabled directories didn't exist, so I had to make them. I have only two files in my /etc/nginx/sites-available directory - default and mydjangoproject. Both have the same contents and both have their symbolic links in /etc/nginx/sites-enabled. Their contents are: server { listen 8000; server_name 127.0.0.1; location = /favicon.ico { access_log off; log_not_found off; } location /production_static/ { root /home/john/Documents/Django_projects/mydjangoproject/Version_2/mydjangoproject; } location / { proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:8000; } } Here are … -
Generate video requests to a server running at an IP and Port
I have a simple question that can I generate traffic (or not) on a (self-created and accessible) video server that is running on port 8000? I want to generate the traffic for a specific process, not on an IP (what most of the tools provide). So far, I am unable to find any tools that allow us to generate traffic on a specific port. If there is any, please inform me about the options that are available. Actually, I want to observer/analyze the traffic statistics using any monitoring tools. The video server is written in python3 created under Django Framework.
