How do I resolve the "no-name-in-module" error in Pylint when using Parler's TranslatedFields?
I have the following class in models.py: class Family(models.Model): code = models.CharField(max_length=50, unique=True) translations = TranslatedFields(name=models.CharField(max_length=255)) When I try to import the "FamilyTranslation" model for various purposes from .models import FamilyTranslation Pylint detects the "E0611:no-name-in-module" error. The table with the translations is created, the code works, but Pylint doesn't recognize the model. I have tried some pylint plugins to make Parler's automatic models recognized, but it doesn't work. I have already checked the __init__.py file, and it is correct. If possible, I would prefer not to explicitly declare all the "Translation" models from Parler. -
How to fix a bug after stripe paymant
I have a website with games. I also included stripe as a payment method, and everything works pretty fine! But, after you finish your payment, you get redirected to your home page, and objects that are looped just DISSAPPEAR! They appear again once you travel from one page to another. Views.py def button_to_buy(request): stripe.api_key = settings.STRIPE_SECRET_KEY checkout_session = stripe.checkout.Session.create( payment_method_types=[ 'card', ], line_items=[ { 'price': '', 'quantity': 1, }, ], mode='payment', success_url=request.build_absolute_uri(reverse('success')) ) return redirect(checkout_session.url, code=303) def success_url(request): user = request.user.pk profile = Profile.objects.get(user_id=user) profile.subscription = True profile.save() messages.success(request, 'Оплата прошла успешно') return render(request, 'store/index.html') Urls.py path('checkout/', button_to_buy, name='checkout'), path('success/', success_url, name='success'), Profile.html <div class="justify-content-center py-4 px-2"> {% if not profile.subscription %} <form action="{% url 'checkout' %}" method="POST"> {% csrf_token %} <button class="btn text-light bg-danger mt-4">Buy subscription</button> </form> {% else %} <button class="btn text-light bg-success mt-4">Already paid</button> {% endif %} -
How to speed up celery task which add info into DB
I'm using Django with Celery and PostgreSQL I wrote a celery task which takes json from 3rd party api with more than 10k lines and write them into my database but it takes kinda slow like 30 seconds or more and i'm wondering is there a way to speed up this task? @app.task def create_presence_info(): url = 'http://3rd_party_api.com/api' enter code here response = requests.get(url).json() if len(response) <= 0: print('JSON IS EMPTY') elif len(response) > 0: for item in response: obj_json = json.dumps(item) info_parsed = PresenceInfoListSerializer.parse_raw(obj_json) for counter_list in info_parsed.ListOfCounterparty: presence_list_model = check_presence_list(counter_list) object_list_model = check_object(info_parsed.ObjectGUID) set_of_presence_model = set_of_presence_guid(PresenceListInfo, counter_list) if presence_list_model is None or presence_list_model.GUID not in set_of_presence_model: presence_info = PresenceListInfo.objects.create(GUID=counter_list.DocumentGUID, object_presence=object_list_model) set_of_presence_model.add(presence_info.GUID) deleted = False for info in counter_list.Information: counter_party_model = check_counter_party(info.CounterpartyGUID) if not deleted: PresenceDetailInfo.objects.filter(presence_info=presence_list_model).delete() deleted = True details = PresenceDetailInfo.objects.create(presence_info=presence_list_model, counter_presence=counter_party_model, work_date=counter_list.Date, amount_of_workers=info.Number) for section in info.SectionsGUID: sections = None try: sections = CleanSections.objects.get(GUID=section) except CleanSections.DoesNotExist as sections_error: logger.error(f'{sections_error} update_or_create_presence_info') PresenceSectionList.objects.create(presence_detail=details, presence_sections=sections) ``` -
sqlAlchemy jsonb in Django form
I have a PostgreSQL database and use sqlAlchemy to access the data. In one of the tables, I have a JSONb column. When I load a sqlAlchemy object (an entry from the DB) containing a not empty JSON entry sqlAlchemy will directly transfer it to a Python dict. On default, for Python dicts single quotes are used; therefore, even though JSON uses double quotes, the dict is with single quotes. I then show the JSON in a Django form field so that a user might update the JSON and/or other parameters. When I get the form back with the content of the JSON field as an str, I want to validate that the user sends a valid JSON, so I execute json.loads(json_form_field_content) to verify it. This will raise an error if single quotes are in the JSON string. This is especially bad as this will even happen if the user has not changed the JSON. I googled hard and didn't find a fitting solution for my problem, so I thought hard and came up with an in my option poor solution. I use the following code to transfer the dict to a string where I explicitly set double quotes for … -

Use IntegrityError exception (in Django) to check if username is taken?
I wanted to create a signup form in Django and throw an error if the username already exists. I have seen people have used User.DoesNotExist() method to check that, but can you use IntegrityError exception as follows for that purpose? I have read the definition of IntegrityError but honestly do not quite understand this: This exception is raised when the relational integrity of the data is affected. def signup(request): if request.method == 'GET': return render(request, 'signup.html', {'form': UserCreationForm}) else: if request.POST['password1'] == request.POST['password2']: try: user = User.objects.create_user(request.POST['username'], password=request.POST['password1']) user.save() login(request, user) return redirect('home') except IntegrityError: return render(request, 'signup.html', {'form': UserCreationForm, 'error': 'Username already exists'}) else: return render(request, 'signup.html', {'form': UserCreationForm, 'error': 'Passwords do not match'}) I have seen this code in a Django project. I would appreciate your feedback. -

How to configure SSL certificate inside my docker container?
I have a django application that running inside a docker container. However, while the application works perfectly fine inside my local PC when running inside the container it is unable to make any requests such as calling certain APIs or even pip install. All of these actions will throw an error like [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:992). Only way I got pip install working is to do RUN pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host=files.pythonhosted.org --no-cache-dir -r requirements.txt Solutions tried: Copying my local rootCA.pem file to /usr/local/share/ca-certificates/ in the container RUN update-ca-certification Tried different python providers (alpine, buster, slim-buster) There are many more I couldn't remember I don't want to just turn verify off as it is bad practice so I'm trying to keep verification on.

GET request to ListAPIView doesn't recognize query parameter in Django Rest Framework test case
I am encountering an issue with my Django Rest Framework test case where a GET request to a ListAPIView doesn't seem to recognize a query parameter. The same request works correctly when sent through Postman, but fails when executed within the test case. Here's an overview of the problem: I have a ListAPIView that represents a collection of model instances. The view works fine when tested manually through Postman, and it expects a query parameter called 'project' to filter the collection based on a specific project. However, when I try to send a GET request to the same ListAPIView within my test case, the query parameter 'project' is not recognized, resulting in an error response indicating that the project field is required. Here's a simplified version of the relevant code in my test case: class ShiftListTests(APITestCase): def setUp(self): self.user = User.objects.create_user(username='testuser', password='testpassword') self.client.force_authenticate(user=self.user) self.project = Project.objects.create(owner=self.user, task='Test Task', technical_requirement='Test Requirement', start='2023-05-01', hourly_rate=10.0) self.shift1 = Shift.objects.create(project=self.project, start_time=timezone.make_aware(timezone.datetime(2023, 5, 1, 9, 0, 0)), end_time=timezone.make_aware(timezone.datetime(2023, 5, 1, 17, 0, 0))) self.shift2 = Shift.objects.create(project=self.project, start_time=timezone.make_aware(timezone.datetime(2023, 5, 2, 9, 0, 0)), end_time=timezone.make_aware(timezone.datetime(2023, 5, 2, 17, 0, 0))) def test_get_shift_list(self): url = reverse('shift list') payload = {'project': self.project.id} response = self.client.get(url, data=payload, format='json') self.assertEqual(response.status_code, status.HTTP_200_OK) # … -

独自ドメインをEC2インスタンスのpublic IPに紐付けたが、そのドメインにブラウザからアクセスできない
実現したいこと： EC2インスタンスのpublic IPアドレスに紐づけた独自ドメイン（= example.com)にアクセスし、GunicornでサーブされているDjangoアプリからの応答を、Nginx as a reverse proxyを通じて、ブラウザに表示したいです。 問題点： public IPアドレスにアクセスすると、Djangoアプリからの応答を確認できます。 example.comにアクセスすると、「このサイトにアクセスできません」となります。 以上より、ドメインの紐付けに失敗していると予測するも、「example.com/admin」にはアクセスできるため、紐付け自体には問題がなさそうです。 やってきたこと： 1, Route53にて独自ドメインとEC２インスタンスのpublic IPを、Aレコード及びネームサーバーの設定を通じて、紐づけました。 2, HTTPアクセスを受けられるように、セキュリティグループでポート８０を開け、ソースを0.0.0.0と設定した。 3, EC2インスタンス内で、Gunicorn/Django、Nginx、PostgreSQLのコンテナたちを、以下のdocker-compose.yml & default.confを用いて作成しました。 version: "3.9" services: web: # コンテナ名をwebに指定 container_name: web # NginxのDockerfileをビルドする build: # ビルドコンテキストはカレントディレクトリ context: . dockerfile: ./nginx/Dockerfile # ボリュームを指定 # ローカルの/staticをコンテナの/staticにマウントする volumes: - ./static:/static - ./nginx/conf.d:/etc/nginx/conf.d - ./etc/letsencrypt:/etc/letsencrypt - ./var/www/html:/var/www/html ports: - "80:80" depends_on: - api certbot: # 後のHTTPS化に使います image: certbot/certbot:v1.7.0 volumes: - /etc/letsencrypt:/etc/letsencrypt - /var/www/html:/var/www/html command: ["--version"] api: build: ./api command: gunicorn server.wsgi:application --bind 0.0.0.0:8000 environment: - OPENAI_API_KEY=${OPENAI_API_KEY} - SECRET_KEY=${SECRET_KEY} - DB_NAME=${DB_NAME} - DB_USER=${DB_USER} - DB_PASS=${DB_PASS} - DB_HOST=${DB_HOST} - DB_PORT=${DB_PORT} volumes: - ./api:/app ports: - "8000" depends_on: - db db: image: postgres:13 environment: POSTGRES_DB: ${DB_NAME} POSTGRES_USER: ${DB_USER} POSTGRES_PASSWORD: ${DB_PASS} volumes: - postgres_data:/var/lib/postgresql/data/ volumes: postgres_data: upstream django { # サーバにDjangoのコンテナ名を指定。今回はapp # ポートはDjangoのコンテナの8000番ポート server api:8000; } server { # HTTPの80番ポートを指定 listen 80; server_name example.com; # プロキシ設定 # 実際はNginxのコンテナにアクセスしてるのをDjangoにアクセスしてるかのようにみせる location / { proxy_pass http://django; } } どうかアドバイス宜しくお願いいたします！ -

DJANGO: database dependent combobox remains empty. No items appear
I would like to create a combobox and display data from a database table (names of cities) inside it. The page is app1/home.html.

AP Scheduler skips logging of the job execution - How to resolve?
This is how my scheduler configuration and the registered job looks like ` from django.core.management import call_command def start(): from django_apscheduler.jobstores import register_events, DjangoJobStore, register_job from apscheduler.schedulers.background import BackgroundScheduler scheduler = BackgroundScheduler() scheduler.add_jobstore(DjangoJobStore(), 'djangojobstore') print("Idhar aagya mein") try: @register_job(scheduler, 'interval', minutes=1, name="daily_bakcup", misfire_grace_time = 300, max_instances=3) def backup(): call_command('DB_Backup') except Exception as e: print("Error" , e) register_events(scheduler) scheduler.start() ` Here is the explanation on what the job does and where the error come. So, the job is to take backup of the database using Django's python manage.py dumpdata > file.json command, then upload it to Azure container. The thing I wanted to achieve is to perform the job and log the execution in the Job Execution tables (which is expected to happen implicitly when jobstores are used.) in the Database. Hence, it performs the job but doesn't log the execution in the tables, instead i get the below in the console. Job 'user_accounts.backup.backup' no longer exists! Skipping logging of job execution... Any suggestions and solution would help a lot. Thanks! -

The following is the error message: Traceback (most recent call last): File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/fields/related_descriptors.py", line 218, in __get__ rel_obj = self.field.get_cached_value(instance) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/fields/mixins.py", line 15, in get_cached_value return instance._state.fields_cache[cache_name] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^ KeyError: 'supertask' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) ^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/core/handlers/base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/crackers/views.py", line 73, in delete print(task.delete()) ^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/base.py", line 1132, in delete return collector.delete() ^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/deletion.py", line 512, in delete signals.post_delete.send( File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/dispatch/dispatcher.py", line 176, in send return [ ^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/dispatch/dispatcher.py", line 177, in <listcomp> (receiver, receiver(signal=self, sender=sender, **named)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/crackers/signals.py", line 10, in reassess_achievement if instance.supertask is not None and instance.supertask.completed == False: ^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/fields/related_descriptors.py", line 236, in __get__ rel_obj = self.get_object(instance) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/fields/related_descriptors.py", line 199, in get_object return qs.get(self.field.get_reverse_related_filter(instance)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/thebjko/dev/TrackCracker/venv/lib/python3.11/site-packages/django/db/models/query.py", line 637, in get raise self.model.DoesNotExist( crackers.models.Task.DoesNotExist: Task matching query does not exist.

django channels app is blocking when handle many requests
i have a DRF project, using django channels, i have a endpoint that handles thousands requests for each 5seconds, sometimes this endpoint is blocking my app, what would be the best way to handle it? some posts adivises to use raise StopComsumer() in the disconect method, but not resolve this is my consumer class ChargerSessionConsumer(AsyncJsonWebsocketConsumer): def __init__(self, *args, **kwargs): super().__init__(args, kwargs) self.client_id = None self.group_name = None async def connect(self): self.group_name = 'room' self.client_id = self.scope["url_route"]["kwargs"]["client_id"] await self.channel_layer.group_add( self.group_name, self.channel_name ) await self.channel_layer.group_add( self.client_id, self.channel_name ) await self.accept() async def websocket_disconnect(self, message): await self.channel_layer.group_discard( self.group_name, self.channel_name ) await self.channel_layer.group_discard( self.client_id, self.channel_name ) raise StopConsumer() -
Add Django super user token in http request
I use Django (as backend and frontend) for a website. I want to create http request with the condition (of use) to be Django super user. But I don't know how to add in the headers the token (or the proof that the user that uses the request is a super user). I tried this with the csrf token : First I use the {% csrf_token %} in the template. <form action="#" id="admin-add-event" method="POST"> {% csrf_token %} ... <button type="submit" id="admin-submit">Add event</button> </form> const url = `${window.BASE_URL}events/`; const form = document.getElementById('admin-add-event'); const data = { ... } let xhr = new XMLHttpRequest(); xhr.open('POST', url , true); xhr.setRequestHeader('X-CSRFToken', form.elements.csrfmiddlewaretoken.value); xhr.setRequestHeader("Content-Type", "application/json"); xhr.onload = function () { ... } xhr.send(JSON.stringify(data)); And in the Django view of the endpoint : @api_view(['GET', 'POST']) def all_events(request): if request.method == 'POST': if not request.user.is_superuser: return Response(status=status.HTTP_401_UNAUTHORIZED) # etc ... But the check of super user fails always I precise that I don't want to implemente a user system. I want to use the system of super user of Django. Thanks in advance ! -
How to use Django ImageField to upload to Google Cloud Storage instead of local
I want to use Django's ImageField on a model so people can upload a logo. I found the ImageField however reading from the docs it says Django stores files locally, using the MEDIAROOT***andMEDIAURL** settings.py I'm wondering how I can change the *upload_to= behavior to upload to a gcp bucket instead? If it's possible when I call .save what is saved to the database, the gcp bucket url? From reading the docs it doesn't say one way or the other if this is possible or if all images should be stored locally where the service is being ran. I have thought of saving the binary images directly to the db but that seems inefficient.
