Django PWA - Periodic Background Sync
I have a django application (not yet PWA) in which I got asked to implement a feature that makes the app upload the users location to an API. This is because the app is used for truck operators. The client wants to be able to follow where the truck is. To monitor if all scheduled deliveries can be succeeded that day. My question: Is it possible to somehow make a background task that, even when the user is not using the app (its closed or not focussed), sends its location to the API? What technologies should I be using for this? I have already looked into a lot of technologies (that for me are very new). Just as PWA (service workers), workers, periodic-background-sync-api, background-sync-api,... But I am getting lost in all the information that there exists. -
Cannot get metadata (current-total) from state/info of celery task after calling update_state
I am building a web application with Django. I need to display a progress bar. To track the progress inside a celery task I am passing an ajax call to the backend containing information needed for the process and another one with a timeout to keep watching for progress of the celery task. I can not understand what I am doing wrong, but I cannot get back the information regarding the information I stored in the 'meta' of the update_state. Following relevant part of code. tasks.py @shared_task def myFunction(): current_task.update_state(state='PROGRESS', meta={'current':0, 'total':100}) . do stuff . current_task.update_state(state='PROGRESS', meta={'current':25, 'total':100}) . do stuff . current_task.update_state(state='PROGRESS', meta={'current':50, 'total':100}) . do stuff . current_task.update_state(state='PROGRESS', meta={'current':75, 'total':100}) . do stuff . current_task.update_state(state='PROGRESS', meta={'current':100, 'total':100}) return result views.py def view(): ****GET PART**** if 'processing' in request.POST: result = myFunction.delay() request.session['id'] = result.id result_out = result.get() return JsonResponse() elif 'checkstate' in request.POST: proc_id = request.session['id'] task = AsyncResult(proc_id) return JsonResponse({'state':task.state, 'info':task.info}) -
How to get the text of a template without parsing the template?
Imagine I have a template that uses a custom template tag. During the processing of the template tag, I discover a problem I could help the user solve. I want to provide a pointer to where the error happened (and what they need to do to solve the problem). How do I get the template text and the current position (line) in the template file? (in a way that doesn't re-parse the template, since that would cause the error to be detected again recursively..) -

Django: Running inspectdb command produces ImportError: cannot import name 'NoArgsCommand'
What I am currently trying to achieve is to map the database that I have in sqlite3 to Django (version 4.1) models. I have tried using inspectdb but it keeps throwing ImportError: cannot import name 'NoArgsCommand' from 'django.core.management.base'. I first tried running the command below: python manage.py inspectdb --database \transactions\db.sqlite3 Which gave me the error: from django.core.management.base import NoArgsCommand, CommandError ImportError: cannot import name 'NoArgsCommand' from 'django.core.management.base' (C:\Users\E.Musonda\AppData\Local\Programs\Python\Python310\lib\site-packages\django\core\management\base.py) I then moved my sqlite3 to my projects base directory and run the command below: python manage.py inspectdb > models.py Which still produced the same error. Django database configuration: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', } } Has anyone encountered this problem before and solved it? Or maybe I'm using the inspectdb command in a wrong way? Any help appreciated! -

Should I create an endpoint per HTTP method in my Django backend application?
I am developing a Django backend application with Django Rest Framework. Apart from having to write a lot of code, is it good practice to have a separate endpoint for each CRUD operation? Say I have an Organization model that I would like to create CRUD endpoints for. My usual approach is to create an endpoint ListCreateOrganization(generics.ListCreateAPIView) and map that to the path /organization/. Then create another endpoint /organization/<int:pk>/ for a RetrieveUpdateDeleteOrganization(generics.RetrieveUpdateDestroyAPIView) (assuming all CRUD operations apply). What are the scalability and performance concerns of this approach? What about creating five endpoints and mapping that to each operation: Create - /organization/create List (get multiple instances) - /organization/list/ Get a single instance - /organization/<int:pk>/retrieve/ Update a single instance - /organization/<int:pk>/update/ Delete a single instance - /organization/<int:pk>/delete/ -

Difference between calling user.save() and create_user when using UserCreationForm (or subclass of) and register view in Django

Should it even be used? What are the best practices? -

Django: password is being saved plain text in MySQL Database
I'm trying to register user. When i'm creating superuser, password is being saved correctly, however when i'm registering the user through the api, it's being saved as plain text. My RegisterSerializer: from django.contrib.auth.models import User from rest_framework import serializers, validators class RegisterSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('username', 'password', 'email', 'first_name', 'last_name') extra_kwargs = { "password": {"write_only": True}, "email": { "required": True, "allow_blank": False, "validators": [ validators.UniqueValidator( User.objects.all(), "A user with that Email already exists" ) ] }, 'first_name': {"required": True}, 'last_name': {"required": True} } def create(self, validated_data): user = User( email=validated_data.get('email'), username=validated_data.get('username'), first_name=validated_data.get('first_name'), last_name=validated_data.get('last_name'), ) user.set_password(validated_data.get('password')) user.save() return user views.py register request: @api_view(['POST']) def register_api(request): serializer = RegisterSerializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.save() _, token = AuthToken.objects.create(user) return Response({ 'user_info': { 'id': user.id, 'username': user.username, 'email': user.email, 'first_name': user.first_name, 'last_name': user.last_name, }, 'token': token }) -
React JS, Python Django Tutorial - infinite loop componentDidUpdate
I'm following an online video tutorial on creating a CRUD full-stack app with React/Django/Sqlite, but I am running into an infinite loop when fetching any table data. The problem seems to be caused by componentDidUpdate, which is necessary for reloading the table after updating/deleting an entry. Here's a sample code snippet below (links below): refreshList(){ fetch(process.env.REACT_APP_API+'employee') .then(response=>response.json()) .then(data=>{ this.setState({emps:data}); //<=? }); } componentDidMount(){ this.refreshList(); } componentDidUpdate(){ //<= this.refreshList(); } Learn React JS, Python Django by Creating a Full-Stack Web App from Scratch GitHub Source Code Problem Code Snippet -
