Correct use of pytest fixtures of ojects with Django
I am relatively new to pytest, so I understand the simple use of fixtures that looks like that: @pytest.fixture def example_data(): return "abc" and then using it in a way like this: def test_data(self, example_data): assert example_data == "abc" I am working on a django app and where it gets confusing is when I try to use fixtures to create django objects that will be used for the tests. The closest solution that I've found online looks like that: @pytest.fixture def test_data(self): users = get_user_model() client = users.objects.get_or_create(username="test_user", password="password") and then I am expecting to be able to access this user object in a test function: @pytest.mark.django_db @pytest.mark.usefixtures("test_data") async def test_get_users(self): # the user object should be included in this queryset all_users = await sync_to_async(User.objects.all)() .... (doing assertions) ... The issue is that when I try to list all the users I can't find the one that was created as part of the test_data fixture and therefore can't use it for testing. I noticed that if I create the objects inside the function then there is no problem, but this approach won't work for me because I need to parametrize the function and depending on the input add different groups … -
simpleJWT confirm password field
I'm creating a small app that uses simpleJWT. I want the user to retype their password when registering. Currently, I'm sending data like this { "email":"test", "user_name":"test3", "password":"b12@wsqp" } But what I want to validate is { "email":"test", "user_name":"test3", "password":"b12@wsqp", "password2":"b12@wsqp" } What i have now is class CustomUserCreate(APIView): permission_classes = (AllowAny,) def post(self, request): reg_serializer = RegisterUserSerializer(data=request.data) if reg_serializer.is_valid(): new_user = reg_serializer.save() if new_user: return Response(status=status.HTTP_201_CREATED) return Response(reg_serializer.errors, status=status.HTTP_400_BAD_REQUEST) class RegisterUserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('email', 'user_name', 'password') extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): password = validated_data.pop('password', None) instance = self.Meta.model(**validated_data) if password is not None: instance.set_password(password) instance.save() return instance So my guess is to do class RegisterUserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('email', 'user_name', 'password1', 'password2') extra_kwargs = {'password': {'write_only': True}, 'password2':{'write_only': True}} def create(self, validated_data): password1 = validated_data.pop('password1', None) password2 = validated_data.pop('password2', None) instance = self.Meta.model(**validated_data) if password1 is not None and password2 is not None: if password1 == password2: instance.set_password(password) else: #return some error instance.save() return instance How can I validate if the password are matching? -
Chrome Extension Requesting django server
I am creating a chrome extension that requires a back end server for processing. I would like it to send data to the server, the server will process this data and send some other data back to the user. Preferably this back end server should be in python as there are libraries I would like to use. Any idea how to go about this? I was thinking to use a django server with rest API but I'm not sure what would be best. If anyone could provide a tutorial link or briefly explain the code behind this idea it would be brilliant. -

Django filter objects and do not select objects if there are objects that were created before them with same field value
I'm trying to do a get_queryset for ModelList view, but I only want to select those records that don't have other records with the same event_id in front of them. For example, we have two records. The second record is a child of the first one, and therefore, I don't want to select this second record from the database because it will already be in the children field of the first record. The children field is generated in the serializer, and does not exist in the database.

Add method imports to shell_plus with alias
I have a model naming collision in my django models, with 2 models called Tag in separate modules. That looks something like this: . ├── conversations/ │ └──models.py <- contains a model called Tag └── dogs/ └──models.py <- contains a model called Tag In shell_plus I want to import each module with an alias in SHELL_PLUS_POST_IMPORTS so that it's available when I start the shell. How can I do this? As an example, if i were doing this manually in shell_plus I'd write: # These are the imports I want to happen automatically: from conversation import models as conversation_models from dogs import models as dog_models # Then I can write: conversation_models.Tag() dog_models.Tag() -

python request para aplicativo da minha empresa
Tenho três tabelas em uma aplicação python que precisam ser relacionadas para criar uma lista com nomes advindos de um resultado de uma querie, porém em uma das tabelas só há um argumento que conecta todas. Tenho tentado reproduzir essa querie sql no python porém sem mt sucesso "select * from sicei.lotamento as lotamento, sicei.estagiario as estagiario where estagiario.status='1' and lotamento.status='1' and lotamento.lotacao_id='1'; " e utilizado uma função com get_object_or_404, semelhante a este exemplo abaixo: def det_vagas(request, ): est = get_object_or_404(Lotamento, ) lotamento=Lotamento.objects.filter() estagiario = Estagiario.objects.filter() context={'lotamento': lotamento, 'estagiario':estagiario} return render(request, 'mapas_de_vagas/detalhes.html', context) mas não to conseguindo fechar a querie, por dificuldade em entender a lógica relacional mesmo, sendo que a terceira tabela, só cria uma lista aonde eu deveria capturar o valor de uma coluna (lotacao_id) para obter o resultado que preciso. Será que conseguem me ajudar? Meio desesperado pq não to conseguindo. '-' Tentei utilizar uma função baseada em classe, mas o filtro deu ruim, e tentei trocar os argumentos porém sem resultados. -
In Django, passenger_wsgi.py is calling itself creating infinite processes
We are using Angular JS for frontend and Django framework at backend. Whenever a request comes from the front-end, passenger_wsgi file receives the request. It processes the request and returns the expected response. However, passenger_wsgi calls itself, which calls itself. This happens recursively, in an loop causing infinite processes and server to overload. Appreciate your comments and a fix. Below is the current passenger_wsgi. import os import sys import django.core.handlers.wsgi from django.core.wsgi import get_wsgi_application # Set up paths and environment variables sys.path.append(os.getcwd()) os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings' # Set script name for the PATH_INFO fix below SCRIPT_NAME = os.getcwd() class PassengerPathInfoFix(object): """ Sets PATH_INFO from REQUEST_URI because Passenger doesn't provide it. """ def __init__(self, app): self.app = app def __call__(self, environ, start_response): from urllib.parse import unquote environ['SCRIPT_NAME'] = SCRIPT_NAME request_uri = unquote(environ['REQUEST_URI']) script_name = unquote(environ.get('SCRIPT_NAME', '')) offset = request_uri.startswith(script_name) and len(environ['SCRIPT_NAME']) or 0 environ['PATH_INFO'] = request_uri[offset:].split('?', 1)[0] return self.app(environ, start_response) # Set the application application = get_wsgi_application() application = PassengerPathInfoFix(application) I have tried changing the last 2 lines. In this scenario, passenger_wsgi is not able to serve the request and frontend received 500 Server Error. -
Is there a form field in Django that allows you to enter multiple values one at a time?
I could also use a TextField, but that's not ideal from UX point of view. I would like to know if there's a field that allows the user to enter multiple custom strings (not from a pre-defined list of options), one at a time, where, to enter a string, one needs to press enter, these values are then passed as a list of strings (or other types) to the model, which defines an ArrayField. I've searched for some time, but I couldn't find it. I'm not really an expert in Django, but I suppose such a field must exist. If not, I suppose I could create a custom form field that does that. Here's what I mean. In the example, 1 was written, then the user pressed ENTER, and the option was added; then the same thing happened to add 2; the important thing to note is that 1 and 2 do not come from a predefined set of values, but were custom strings entered by the user, which can also be removed after having been entered. -

Getting error "'list' object is not callable" for authentication_classes
I have following method: @action(detail=False, permission_classes=(IsOwnerOrReadOnly,)) @debugger_queries def get_xyz(self, request, pk=None): # ... Inside this method, request.user was always AnonymousUser. I felt that it was because I did not specify any kind of authentication for this method.
