How to implement SQLAlchemy Postgres async driver in a Django project?
I have come across really weird behavior implementing SQLAlchemy in my Django project using the asynchronous Postgres driver. When I create a SQLAlchemy Session using a sessionmaker and then execute a simple SELECT statement within a session context manager, it generates the correct result the first time, but the proceeding attempts result in a RuntimeError exception stating "Task ... attached to a different loop". I looked up the error and it usually indicates that the session is persisted across multiple Django requests; however, in my code, I don't see how that is possible since I am creating the database session within the request using the sessionmaker and using the session context manager to close it. It gets weirder when reloading the page for a 3rd time using the session context manager approach because the RuntimeError changes to an InterfaceError stating "cannot perform operation: another operation is in progress". But when not using the context manager approach and creating the session manually and immediately after using it closing the session it only produces the RuntimeError exception even after the 2nd attempt. And it continues to get weird, when I do the second approach and do not await the session close, then … -

How to pass response from one function to another function using ajax in django HTML?
I am trying to pass flight data which is in dictionary form and this is generated when user searches for flight and selects offer. What I want is the flight data should be passed in the url but user should not be able to read or modify it. Currently, I have passed flight data with {% for flight in response %} href="{% url 'get_detail' flight %}" {% endfor %} but it shows flight information in URL like 127.0.0.1/get_detail/{flightinfohere} . Is there any idea so that I can save this flight data for another function without passing in URL or I can hide this data or encode it? Any help would be appreciated. I tried to use AJAX, but I don't know how to pass the flight data in ajax as it is response of another views.py function. -

Python - Django - cryptocurrency exchange | subscribe to wallet address and inform of deposits
I am developing a cryptocurrency exchange platform with Django. I have two critical questions: In the case of cryptocurrency deposits, Is it correct that I create a separate wallet address for every user, watch the address for every change in balance on the blockchain, and add it to my own database as a deposit? How can I watch all the wallets and be informed of every balance change? Is there a good third party that provides WebSocket service for bitcoin? -

Reverse for 'user_page' with keyword arguments '{'pk': ''}' not found. I beleive my decorators are causing the issue
So my login view takes the user to the home.view but first checks user is logged in and then checks if the user is an admin or not through the decorator 'admin_only'. My user will prove to be false for this scenario (which is expected). The user is then redirected to the user_page view to which first goes through the decorator allowed_users (which will be true) and then the user_page view. My aim is to pass the primary key at login_user view to user_page view but the middle men decorators I believe are causing me problems. views.py @unauthenticated_user def login_user (request): user = None if request.method == 'POST': temp_username = request.POST.get('username') temp_password = request.POST.get('password') user = authenticate(request, username=temp_username, password=temp_password) if user is not None: login(request, user) context = {'user':user} print ('Primary key in login view = ', user.id) return redirect('home', context) else: messages.info(request, "Username or Password is incorrect!") context = {'user':user } return render(request, 'login.html', context) @login_required(login_url='login') @admin_only def home(request, pk): user = User.objects.get(id=pk) context = {'user':user} return render(request,'home.html',context) @login_required(login_url='login') @allowed_users(allowed_roles=['customer']) def user_page(request,pk): user = User.objects.get(id=pk) context = {'user':user} return render(request, 'user.html', context) urls.py #url.py path('user/<int:pk>/', views.user_page, name='user_page') path('', views.home, name='home'), decorators.py def allowed_users(allowed_roles=[]): def decorator(allow_users_view_function): def wrapper_function(request, *args, **kwargs): … -

Can't create links to any Django admin templates beside index.html?

assertRedirects(response) triggers NoReverseMatch error;

The problem being encountered is that the user is not being redirected; a NoReverseMatch error is being raised: Reverse for 'question' with keyword arguments '{'id': 1}' not found. 1 pattern(s) tried: ['questions/(?P<question_id>[^/]+)/$'] self.assertRedirects() is trigger this error within in the test. Yet, I cannot pinpoint why it's being raised when question_id is being passed into the reverse("posts:question", kwargs={"question_id": answer.question.id}) call of assertRedirects()? It's saying that the key is 'id'? class TestEditInstanceAnswerPage(TestCase): '''Verify that a User who has posted an Answer to a given Question has the ability to edit their answer.''' @classmethod def setUpTestData(cls): cls.user = get_user_model().objects.create_user("TestUser") cls.profile = Profile.objects.create(user=cls.user) cls.answer_user = get_user_model().objects.create_user("TheAnswer") cls.answer_profile = Profile.objects.create(user=cls.answer_user) cls.tag = Tag.objects.create(name="Tag1") cls.question = Question.objects.create( title="How do I get an answer to my post", body="This is the content that elaborates on the title that the user provided", profile=cls.profile ) cls.question.tags.add(cls.tag) cls.answer = Answer.objects.create( body="This is an answer in response to 'How do I get an answer to my post'", question=cls.question, profile=cls.answer_profile ) cls.data = { "body": "This … -
django-elasticsearch-dsl Object of type 'AttrList' is not JSON serializable
I have a Django application where I need to implement a search system, for this application, elasticsearch seems to be the most suitable, but I came across a problem that I can't solve.

Django: How to store certain objects of a model in another model
I am currently trying to create a user profile that will contain the courses that the user chose. Currently, the user profile model is UserProfile and the courses are objects of Course. I've tried using the ManyToMany field but that just results in UserProfile storing all courses in Course. The two models are stored in different apps. models.py class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default="default.jpg", upload_to="profile_pics") courses = models.ManyToManyField("course.Course", blank=True, default=None, related_name = "courses") def __str__(self): return f"{self.user.username} Profile" Any help is appreciated. Thanks.
