How can RetrieveUpdateDestroyAPIView supports POST?
I successfully implement Rest API to store IP address and Mac address mapping. The GET/PATCH/DELETE methods are supported, for example: curl -X GET -H 'Content-Type: application/json' -d '{"ip_address": "192.168.1.1"}' http://127.0.0.1:8000/api/ipmac/ curl -X PATCH -H 'Content-Type: application/json' -d '{"ip_address": "192.168.1.1", "mac_address": "aa:bb:cc:dd:ee:ff"}' http://127.0.0.1:8000/api/ipmac/ However, POST is not supported in RetrieveUpdateDestroyAPIView. I don't wanna create another endpoint for POST method. How to have only one endpoint and support all the methods? Here is my code: models.py from django.db import models class IPMacMapping(models.Model): ip_address = models.GenericIPAddressField(unique=True) mac_address = models.CharField(max_length=17, unique=True) created_at = models.DateTimeField(auto_now_add=True) serializers.py from rest_framework import serializers from .models import IPMacMapping class IPMacMappingSerializer(serializers.ModelSerializer): class Meta: model = IPMacMapping fields = '__all__' urls.py from django.urls import path from .views import IPMacMappingRetrieveUpdateDestroy urlpatterns = [ path('ipmac/', IPMacMappingRetrieveUpdateDestroy.as_view(), name='ipmac-list-create') ] views: from rest_framework import generics from .models import IPMacMapping from .serializers import IPMacMappingSerializer from django.shortcuts import get_object_or_404 class IPMacMappingRetrieveUpdateDestroy(generics.RetrieveUpdateDestroyAPIView): queryset = IPMacMapping.objects.all() serializer_class = IPMacMappingSerializer lookup_url_kwarg = "ip_address" def get_object(self): result = get_object_or_404(IPMacMapping, ip_address=self.request.data["ip_address"]) return result -
How to set up periodic tasks automatically
I have a celery task in one of my django apps. My django, celery and django-celery-beat services are ran in their own docker containers. Since this is a legacy project, I now assume they interact smoothly already with the current config. What I want is that when the app gets deployed/started it finds my perioidc tasks automatically and registers them in the django celery beat database tables. My task: # project.an_app.tasks.generate_statements from config import celery_app @celery_app.task(...) def generate_statements(): print("Statment generation runs. Current date and time:", datetime.now()) # my task logic This is one solution I've found. But this only gets triggered when I try to access the Periodic tasks tables via admin site (probably would be triggered other ways which interact with these tables, but I don't want to "wait" for anything like that). def schedule_task(): interval, _ = IntervalSchedule.objects.get_or_create( every=30, period=IntervalSchedule.SECONDS, ) PeriodicTask.objects.get_or_create( interval=interval, name="generate-statements", task=project.an_app.tasks.generate_statements, ) schedule_task() Looking at our legacy code I've found this, this one looks from project.an_app.tasks import generate_statements @celery_app.on_after_finalize.connect def register_periodic_tasks(sender, **kwargs): """ Callback for Celery to register periodic tasks. """ sender.add_periodic_task( 30.0, task=generate_statements, name="generate-statements", ) The task of the copied code is indeed already django_celery_beat_periodictask table. So I would say this works. However … -
Reusing the types from the DjangoObjectType in the graphene
I have created the PreferencesNode from the DjangoObjectType which contains the gateway provider as TextChoices. class GatewayProvider(models.TextChoices): STRIPE = "stripe", "Stripe" RAZORPAY = "razorpay", "Razorpay" class PreferencesNode(DjangoObjectType): class Meta: model = Preferences exclude_fields = ("user_id",) Now I want to use AccountPreferencesGatewayProviderChoices enum (created via PreferencesNode). How can I do this? Currently I am creating another enum inheriting graphene.Enum. class GatewayProviderEnum(graphene.Enum): STRIPE = GatewayProvider.STRIPE.value RAZORPAY = GatewayProvider.RAZORPAY.value But this is creating redundant enum type. -
Polling a Celery Task with Ajax
I have a Celery task that populates a PostgreSQL database over the course of a few minutes. I want to retrieve the current data from the database in a Django view and send it to a template where it will be constantly re-displayed according to the progress of the task. So, I want to update the template in real-time. Currently, I have a view that calls the Celery task and gets the result of the task. It then renders the template and sends it the result of the task in the form of a string, as well as the id of the task. I am not very familiar with AJAX, but from what I've read I will need another view that AJAX will call to retrieve the most up-to-date result of the task. Here is the code so far: View that renders the template: def dashboard(request): result = prepare_database.delay() result_str = result.get() return render(request, 'appname/template.html', {'task_id': result.task_id(), 'str': result_str}) View that gets the current data def current_data(request): task_id = request.GET.get('task_id') if task_id: async_result = AsyncResult(task_id) return JsonResponse({'data': async_result.get()}) Ajax to poll the task (again, very new to AJAX): $.ajax({ url: '/current_data/', method: 'GET', data: { data: 'data' }, success: function(response) … -
How to get 'value' attribute of tag <input> in Django?

Strange issue using CryptoJS, encrypts fine but decrypts just shows a blank file
I'm creating a browser based Django app that allows a user to upload some files to encrypt and then to decrypt using a password. I have managed to get the encryption part working but when decrypting the files all return blank. I've read through the CryptoJS docs and searched around but can't find a solution that works.

unknown redirect problem while using django view functions
"My URL configuration code: path("get_attendance/", staff_views.get_attendance, name="get_attendance") I placed the get_attendance method in the staff_views.py file. When a user accesses the page with a staff role and makes a POST request to /get_attendance/, it returns a status code of 200, which is normal. However, when a user accesses the page with an admin role and makes a POST request to /get_attendance/, it returns a status code of 302 for a redirection response, and then the user is redirected to the /admin/home/ page." I tried placing the method in two different routes to simulate requests, but the result is still the same. When the user is staff, it returns normally, but when the user is admin, it still redirects without any response But when I moved the get_attendance method into the views.py file, both staff and admin users can now receive a response without redirection. -

Getting 'QuerySet' object has no attribute 'append' when making a function that automatically add a certain value from a ManyToManyField in Django
I am making a dictionary, and one of the features is to detect any input that is similar in the Censorships model. The reason for that is to give a tag for vulgar words. This is my Word model the tag is also in the same file, model.py. `class Word(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) # Attributes of the model word = models.CharField(max_length=120) # Tags for searching and label tags = models.ManyToManyField('Tag', blank=True, related_name="word_tag") class Tag(models.Model): name = models.CharField(max_length=50)` My forms.py looks like this, it contains forms for both word and tag model. `class RawWordForm(forms.Form): word = forms.CharField(widget=forms.TextInput(attrs={"placeholder": "Enter a word"})) tags = forms.ModelMultipleChoiceField( queryset=Tag.objects.all(), widget=forms.CheckboxSelectMultiple ) user = forms.ModelChoiceField(queryset=User.objects.all(), widget=forms.HiddenInput) class RawTagForm(forms.Form): name = forms.CharField(widget=forms.TextInput(attrs={"placeholder": "Enter a tag"}))` Now the censorship occurs in the views.py where the word will be inputted.

Neovim unable to detect Django packages: Getting 'Unable to import 'django.*' error
I've recently configured Neovim for my development workflow, but I'm encountering an issue with Django packages not being detected properly. Whenever I try to import any Django package or use Django functions within Neovim, I receive an error message like this: Unable to import 'django.conf' I've ensured that Django is properly installed and working outside of Neovim, but within Neovim, it seems to have trouble locating the Django packages. I've checked my Neovim configuration and paths, but I'm not sure where the problem lies. Has anyone encountered a similar issue with Neovim and Django packages? How can I troubleshoot and resolve this problem to get Neovim to properly detect Django packages? Any help or suggestions would be greatly appreciated. Thank you! -
How to log in an user coming from an external link into django application
I have a Django application using the out-of-the-box Django authentication system. I need to make an integration with another web app. The users in the other web app will click a button that should take them to my web application and give them access. The other web app will send me the user's email and other data. I should create the user if it doesn't exist without asking for any credentials. I'm not sure what approach I should take. I want something simple but not too insecure. Is SSO or OAuth the way to go? I think this is generally used to sign in with Google or Facebook, etc, but in this case, we don't want to depend on Google/Facebook accounts, the users use business emails. I'm thinking of having the third-party app use a secret key to encrypt an API Token, when the user clicks the button on their app, they will send a redirect to my app with the user data and the encrypted token.

I've been beating my head against a wall here trying to solve this, but I keep getting the following error that I can't resolve whenever I try to yarn add something and then use it: PM [vite] Internal server error: Failed to resolve import "@mui/x-data-grid" from "src/components/formSubmit.tsx". Does the file exist? Could I be somehow screwing up my node_modules? I think my docker script is correct, and I've checked that it exists in node_modules on the image, but I still seem to be getting this issue. My folder structure is: --Myapp |--frontend -node_modules -package.json -index.html - public - src - App.tsx - index.tsx - components - formsubmit.tsx - tsconfig.json - vite.config.js - vite-env.d.ts |--compose |--local |--react |--django |--djangobackend Docker-compose: version: '3' volumes: myapp_local_postgres_data: {} myapp_local_postgres_data_backups: {} services: django: build: context: . dockerfile: ./compose/local/django/Dockerfile image: myapp_local_django container_name: myapp_local_django depends_on: - postgres volumes: - .:/app:z env_file: - ./.envs/.local/.django - ./.envs/.local/.postgres ports: - '28000:8000' command: /start react: build: context: . dockerfile: ./compose/local/react/Dockerfile image: myapp_react container_name: myapp_react depends_on: - postgres - django volumes: - ./frontend:/app - /app/node_modules/ ports: - 28001:3000 environment: - NODE_ENV=development command: yarn start Frontend dockerfile: ARG BUILD_ENVIRONMENT=local FROM node:lts-bookworm-slim WORKDIR /app COPY ./frontend/package.json . #COPY ./frontend/yarn.lock .

Reducing docker image size: multistage build or other suggestions
I am trying to deploy my Django app with docker. This is my original docker file FROM python:3.10.5-slim ENV DockerHOME = /app WORKDIR $DockerHOME COPY requirements.txt . RUN pip install --upgrade pip COPY . $DockerHOME RUN pip install --nocache-dir -r requirements.txt EXPOSE 8000 CMD ["python", "manage.py", "runserver"] After it build however, the image size was 300MB which was too big. I then tried doing a multi stage build as follow (which according to google can help reduce the image size significantly): FROM python:3.10.5-slim as base ENV DockerHOME = /app WORKDIR $DockerHOME COPY requirements.txt . RUN pip install --upgrade pip RUN pip install --nocache-dir -r requirements.txt FROM python:3.10.5-slim COPY --from=base $DockerHOME $DockerHOME COPY . $DockerHOME WORKDIR $DockerHOME EXPOSE 8000 CMD ["python", "manage.py", "runserver"] But this also resulted in an image that was 300MB. Could someone help me with this? I have 2 questions: Is the multistage Dockerfile logical? I feel that there is something wrong which would explain why there was no significant reduction in the image size. Are there any other ways to reduce the image size? I was originally using 'FROM python:3.10.5' instead of 'FROM python:3.10.5-slim' and that gave me 600MB image size. I changed to slim and it … -

CSV file not coming through on submission of html form via POST method (in the context of using Django)
I am building a very simple application which includes one page where a user submits a list of zip codes and then is returned a file with zip codes in a certain radius of the original list. My problem is that my function for processing the file that is contained in the views.py file is not able to retrieve the '.csv' file after the post form. The FILES metadata on the request is missing and I cannot figure out why. More details below: Error I am seeing: Internal Server Error: /zip_app/ Traceback (most recent call last): File "/home/louis/.cache/pypoetry/virtualenvs/zip-radius-app-1xSGHScf-py3.10/lib/python3.10/site-packages/django/utils/datastructures.py", line 84, in __getitem__ list_ = super().__getitem__(key) KeyError: 'csvFile' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/louis/.cache/pypoetry/virtualenvs/zip-radius-app-1xSGHScf-py3.10/lib/python3.10/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) File "/home/louis/.cache/pypoetry/virtualenvs/zip-radius-app-1xSGHScf-py3.10/lib/python3.10/site-packages/django/core/handlers/base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/home/louis/.cache/pypoetry/virtualenvs/zip-radius-app-1xSGHScf-py3.10/lib/python3.10/site-packages/django/views/decorators/csrf.py", line 65, in _view_wrapper return view_func(request, *args, **kwargs) File "/home/louis/Documents/github/zip_radius_tool/zip_radius_app/zip_app/views.py", line 30, in index f = request.FILES['csvFile'] File "/home/louis/.cache/pypoetry/virtualenvs/zip-radius-app-1xSGHScf-py3.10/lib/python3.10/site-packages/django/utils/datastructures.py", line 86, in __getitem__ raise MultiValueDictKeyError(key) django.utils.datastructures.MultiValueDictKeyError: 'csvFile' HTML for the index page where the user submits the .csv file: <!DOCTYPE html> <html lang="en"> <head> <title>W3.CSS Template</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css"> <link rel="stylesheet" …
