How to make a triple sub-layers Choicefiled in Django?
I noticed that the official document has mentioned two-layer choiceFiled only. When I code a three-layer data structure, a notification pops out.

Django Testing Using AsyncClient and Authentication
I have a basic Asynchronous Class Based View: class AsyncAuthenticationView(View): async def post(self, request, *args, **kwargs): authenticated: bool = await sync_to_async(lambda: request.user.is_authenticated)() if not authenticated: return HttpResponse('Unauthorized', status=401) return HttpResponse('Success', status=200) And two simple tests: @pytest.fixture def authenticated_async_client(user) -> AsyncClient: client = AsyncClient() client.force_login(user) return client class TestAsyncAuthenticationView: @pytest.mark.asyncio async def test_with_async_client(self, authenticated_async_client: AsyncClient): """This test fails, with response code 401 instead of 200""" response = await authenticated_async_client.post( reverse('auth-test'), 'abc', content_type="text/html", ) assert 200 == response.status_code # fails with 401 @pytest.mark.asyncio async def test_with_async_request_factory(self, async_rf: AsyncRequestFactory, user): """This test succeeds correctly with response code 200""" r = async_rf.post('/fake-url', 'abc', content_type='text/html') r.user = user r.session = {} response = await AsyncAuthenticationView().post(r) assert 200 == response.status_code The first test which uses the AsyncClient always fails to authenticate returning status code 401 while the second test is passing just fine with status code 200. Based on the docs the AsyncClient has all the same methods, so I am not not why the test is failing. Perhaps there is a different authentication method that needs to be used? The AsyncRequestFactory that is being used in the second test is from the pytest-django package. Any help would be much appreciated. Thank you. -

Django application slow due to multiple foreign keys
I'm having trouble displaying and modeling in django with multiple foreign keys. When displaying or creating it takes a long time as I have a lot of data. For example when trying to create with CreateView it takes a long time, or when trying to display the stored data. Is there any way to optimize the creation and at the time of display? The models with multiple foreging key and ManyToManyField are the following: class Player(models.Model): name = models.CharField("Nombre", max_length=100, blank=True, null=True) player = models.ForeignKey(Socio, on_delete=models.CASCADE, related_name="player_socio") division = models.ForeignKey(Division, on_delete=models.CASCADE,related_name="player_division", blank=True, null=True) goals = models.IntegerField("Goles", default=0) league = models.ForeignKey("League", on_delete=models.CASCADE, related_name="player_league") class Team(models.Model): team = models.CharField("Equipo", max_length=50, blank=True, null=True) league = models.ForeignKey("League", on_delete=models.CASCADE, related_name="team_league", blank=True, null=True) players = models.ManyToManyField(Player, blank=True, related_name="player_team") class Match(models.Model): league = models.ForeignKey(League, on_delete=models.CASCADE, related_name="match_league") date = models.DateField("Fecha", default=timezone.now) week = models.IntegerField("Semana", default=0) team_1 = models.ForeignKey(Team, on_delete=models.CASCADE, related_name="team_1_goal") team_2 = models.ForeignKey(Team, on_delete=models.CASCADE, related_name="team_2_goal") class Goal(models.Model): goal = models.IntegerField("Goles", default=0) match = models.ForeignKey(Match, on_delete=models.CASCADE, null=True, blank=True, related_name="match_goals") player = models.ForeignKey(Player, on_delete=models.CASCADE, null=True, blank=True, related_name="player_goal") league = models.ForeignKey("League", on_delete=models.CASCADE, related_name="player_league_goal") And when creating or displaying the data I use class-based views.

@apollo/client useLazyQuery .then() triggers even when there's an error (React/graphene-django)
I have a graphene-django backend with a me query that returns an exception: You do not have permission to perform this action if the user is not logged in. From React I'm calling the query like this: const [getMe] = useLazyQuery(ME_QUERY); // query not important React.useEffect(() => { getMe() .then((meRes) => { console.log('Hit the .then()'); if (meRes.data && meRes.data.me) { setUser(meRes.data.me); } }) .catch(() => { console.log('Hit the .catch()'); }); }, []) The response I get from the backend: {"errors":[{"message":"You do not have permission to perform this action","locations":[{"line":2,"column":3}],"path":["me"]}],"data":{"me":null}} I would expect that @apollo/client would recognize this as an error and my console would output Hit the .catch(), but for some reason it's not hitting the catch at all and only outputs Hit the .then(). Why would that response resolve instead of reject in @apollo/client? I only have this issue with queries, not with mutations which work as expected. For instance if I call this mutation: const [createUser, { data, loading, error }] = useMutation(CREATE_USER_MUTATION); createUser({ variables: { email, password1, password2, }, }).then(() => { console.log('this should not be hit'); }); And I receive this response: {"errors":[{"message":"['This password is too short.

How to return a random number asynchronously using AJAX and Django
As a beginner I apologize to being not particular as you wish, but hopefully you'll understand my problem. What I am trying to achieve is simply returning a random value every 1.5 seconds without manually refreshing the browser.

Is there any possibilty to have just one function that actually does the same as these two or any cleaner way to achieve this? views.py: def generate_random(request): return render(request, "form.html") def generate_number(request): return HttpResponse(randint(0, 30)) my form.html is: <head> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> </head> <body onload="getRandomInt();"> <h2 id="result"></h2> <script> function getRandomInt() { setTimeout(function () { $.get("url", function(data, status){ $('#result').html(data); }); getRandomInt(); }, 1500) return false; } </script> </body> and urls.py: urlpatterns = [ path('',generate_random), path('url',generate_number), ] -

But when i run a debugger i get an error saying : Internal Server Error: /login/ Traceback (most recent call last): File "c:\Users\moham\OneDrive\Desktop\Granular\web solution\web_solution\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "c:\Users\moham\OneDrive\Desktop\Granular\web solution\web_solution\lib\site-packages\django\core\handlers\base.py", line 181, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\moham\OneDrive\Desktop\Granular\web solution\Chosen_granular\apps\authentication\views.py", line 26, in login_view if (firebase_authentication(user.email,password)): AttributeError: 'NoneType' object has no attribute 'email' And this is how my login view function looks like. def login_view(request): form = LoginForm(request.POST or None) msg = None if request.method == "POST": if form.is_valid(): username = form.cleaned_data.get("username") password = form.cleaned_data.get("password") user = authenticate(username=username, password=password) if (firebase_authentication(user.email,password)): #user = auth.get_user_by_email(user.email) #request['uid']=user.uid login(request, user) return redirect("/") else: msg = 'Invalid credentials' else: msg = 'Error validating the form' return render(request, "accounts/login.html", {"form": form, "msg": msg}) -

Annotate queryset models with fields from "through" model
This seems like it should be easy, but I've been unable to find an answer despite lots of googling. I have two models joined by a many-to-many relationship through a third model that has some additional fields. class User(AbstractUser): pass class Project(models.Model): name = models.CharField(max_length=100, unique=True, blank=False) description = models.CharField(max_length=255, blank=True) users = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='projects', through='UserProject') # additional project fields class UserProject(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) favorite = models.BooleanField(default=False) last_used = models.DateTimeField(default=timezone.now) what I want is to be able to access a given user's projects along with the favorite and last_used fields for that user for each project. I cannot figure out how to do that using annotations or any other method on a call to user.projects. If I call the through relationship directly (i.e., user.userproject_set), I can add fields from the project with a single sql query by calling, e.g., user.userproject_set.select_related('project').annotate(name='project.name'), but then the models in the resulting queryset are UserProjects, not Projects, which is not what I want. Writing a sql query to do what I want would be trivial (it would basically be the same query Django produces to join the Project fields to the UserProject queryset). Is there a way to get … -
nginx, uwsgi, django. uwsgi runs fine as normal user, fails when started by root, even with su -u nonroot
I am trying to get nginx, Django, and uwsgi to work 'as specified' in the docs (well, ok, https://uwsgi.readthedocs.io/en/latest/tutorials/Django_and_nginx.html anyway). Everything works perfectly as long as I start uwsgi as NON-root user.

linking JavaScript code to Django database upon clicking on a button
I'm asked to work on a networking website that is like Twitter. I work with HTML,CSS, Javascript for the client-side and Django for the server-side. I'm trying to link between Javascript and Django using JSON and fetch as I want to create a button in each of the users' profile that upon being clicked by the registered user, it makes the registered follow the profile as it is saved in django database as a model containing the follower(follower) and the user followed(following) but upon clicking on follow button (in user.html) it doesn't save any data in the database in models.py: class follow(models.Model): follower = models.ForeignKey("User",on_delete=models.CASCADE, related_name="follower") following = models.ForeignKey("User",on_delete=models.CASCADE, related_name="following") in user.html(contains the script): <html> <head> <script> document.addEventListener('DOMContentLoaded',function(){ document.querySelectorAll('input').forEach(input =>{ input.addEventListener('click', function(){ console.log(input.id); let follow_username = input.id fetch('/follow/'+ follow_id, { method:'PUT', body: JSON.stringify({ follow: true }) }) }) } ) }); </script> </head> <body> <h2>{{x.username}}</h2> <form> {% csrf_token %} <input type="submit" value="follow" name ="follow" id={{x.username}}> </form> </body> </html> in urls.py: from django.urls import path from . import views urlpatterns = [ path("follow/<str:name>", views.Users, name="follow") ] in views.py: def Users(request, name): x = User.objects.get(username = name) if request.method == 'PUT': data = json.loads(request.body) if data.get('follow') is not None: user = request.user … -
Are user provided translations for user provided templates possible with the django template engine?
In my webapp, I'd like to allow users who want to deploy an instance to write their own templates. Specifically, I would like to include a template for a data protection declaration using the include tag and have this point to a location which users can define in their settings. However, this would not be translatable, as all translated strings have to be in django.po and that file is in version control. Is there a way to extend django.po, e.g. use an include statement to point it to a second, user generated translations file, similar to how I can include templates within other templates? -

Feel like I'm missing a trick here. Any advice or resoucrces would be great.
