Merge two models with one-to-one relationship into one model serializer (Django)
In Django Rest, I have a model named User which is used as AUTH_USER_MODEL. In order to expand this model and separate authentication-related fields with additional information, I have created another model named Profile. Profile contains unrelated data like age, height, country, zip_code, and so on. These two models have one-to-one relationship. I need a special endpoint which is only accessed by admin and used for creating a user and its profile in one request. For this purpose, I need a flat serailizer like this: { "username": "something", "password": "1234", "email": "user@domain.com", "age": 43, "country": "USA" } I tried creating a class inheriting serailizers.Serializer and create fields manually, but this seems very unengineered. Also imagine what happens if later on I add new fields to these models. Also, I could include ProfileSerializer inside UserSerializer and I would have: { "username": "something", "password": "1234", "email": "user@domain.com", "profile": { "country": "USA", // and rest of fields } } I need a flat serializer combining two (or even more) models that have one-to-one relationship.The serializer must contain all required fields of these two models. What should I do? -
Mobile Browser stripping out 10 digit numbers

How to filter an item in one queryset from appearing in another queryset in django
I have a Django view where I am getting the first queryset of 'top_posts' by just fetching all the Posts from database and cutting it in the first four. Within the same view, I want to get "politics_posts" by filtering Posts whose category is "politics". But I want a post appearing in 'top_posts', not to appear in 'politics_posts'. I have tried using exclude but it seems like it`s not working. Below is my view which is currently not working: def homepage(request): top_posts = Post.objects.all()[:4] politics_posts = Post.objects.filter(category='news').exclude(pk__in=top_posts) context={"top_posts":top_posts, "politics_posts":politics_posts} return render(request, 'posts/homepage.html', context) Any help will be highly apprecuiated.

How can I store the response from a third party API as instance in a Django model
I am building a web API in DRF. And there's this third party API whose response returns fields like ip_address, latitude, longitude, etc. I have a user model(which is basically inherited from an AbstractBaseUser) that contains fields like email, username, first_name and last_name. Creating an instance of this user model works. But what I want to do is save response from this third party API as an instance of a model called Artist that has a OneToOneField with the user model whenever an instance of this user model is saved. How can I do this? Note: I am letting Djoser, a third party library for handling authentication, take care of the authentication endpoints on my user model. So no views involved in this project so far yet it works. -
grouping is giving wrong data if order_by is added
I have a model Lead. It has column deal_value. I want to get the count of leads for the given buckets for deal_value. Buckets are from 0 to 1000 --> '<=1000' from 10001 to 100000 --> '<=100000' So I annotate the queryset with 'bucket' and group by bucket and perform aggregation on it. below is the code: import django import os os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'design_studio_app.settings') django.setup() from dashboard.utils import get_accessible_objects_for_a_user from accounts.models import User from dashboard.qfilters import get_q_created_at from django.db.models import Case, When, CharField, Value from django.db.models import Count user = User.objects.get(pk=1529) # get the queryset queryset = get_accessible_objects_for_a_user( 'Leads', user) # get the leads which are created this month queryset = queryset.filter(get_q_created_at('this_month')) queryset = queryset.order_by('deal_value') measure_group_metric = 'deal_value' min_value = 0 max_value = 100000 queryset = queryset.filter( **{measure_group_metric+"__gte": min_value, measure_group_metric+"__lte": max_value}) case_conditions = [ When(**{measure_group_metric+"__gte": 0, measure_group_metric+"__lte": 1000}, then=Value('<=1000')), When(**{measure_group_metric+"__gte": 10001, measure_group_metric+"__lte": 100000}, then=Value('<=100000')) ] queryset = queryset.annotate( bucket=Case( *case_conditions, default=None, output_field=CharField(), ) ) annotated_data = queryset.values('bucket').annotate(count=Count('id',allow_distinct=True)) print(annotated_data) The annotated_data is <SoftDeleteQuerySet [{'bucket': '<=1000', 'count': 26}, {'bucket': None, 'count': 1}, {'bucket': '<=100000', 'count': 8}, {'bucket': '<=100000', 'count': 1}, {'bucket': '<=100000', 'count': 1}]> So the count is wrong. we can see that bucket bucket': '<=100000' is repeated.

Is there a way to use chain and group with celery?
Im building a solution using python, django rest framework, celery and rabbitmq to run some tasks in my api project. However some tasks may be done in parallel and others not. I tried this solution using chord and group, but in these two ways the last task(task_9) never is executed, all the others previous tasks are executed with success. When i tried chord i put task_9 as a callback function, but even this doesn't work.

How can I serialize the Transaction model in django rest framework
There are two reasons why the Transaction model should have a sender and receiver and assign them to the CustomUser model with different related names. It could help answer questions like: Who initiated the Transaction? Who received the funds? We want to serialize this model because our company intends to use React.js as the frontend of the application. I would like to know how to validate the serialization to ensure that the sender can send funds from their account to another. As you can see this view, I created it based on django template: def transfer(request): if request.method == 'POST': account_number = request.POST['account_number'] amount = Decimal(request.POST['amount']) superuser_account = Account.objects.get(user='superuser username') # set this username to the admin username or your preferred account. sender_account = Account.objects.get(user=request.user) receiver_account = Account.objects.get(account_number=account_number) interest_rate = 0.02 deduction = amount * interest_rate if sender_account.account_balance >= amount: sender_account.account_balance -= amount sender_account.save() receiver_account.account_balance += amount receiver_account.save() superuser_account.account_balance += deduction superuser_account.save() Transaction.objects.create( sender=request.user, receiver=receiver_account.user, amount=amount, account_number=account_number ) return redirect ('Transfer') else: messages.error(request, 'Insufficient Funds') return redirect ('Transfer') return render(request, 'transfer.html') This view checks if the sender account balance is greater than or equal to the specified transfer amount. If the sender doesn't have enough funds, it sets an error … -

How to assign user and user.profile to the request object using a single database query in django?
Django assign user to request in the django.contrib.auth.middleware.py by calling request.user = SimpleLazyObject(lambda: get_user(request)) The get_user function is in the init.py file which in turns calls another get_user function in the backends.py def get_user(self, user_id): try: user = UserModel._default_manager.get(pk=user_id) except UserModel.DoesNotExist: return None return user if self.user_can_authenticate(user) else None Here it is making a database call to get user by id.

Cannot redirect with forwardauth Traefik middleware
How to actually switch(redirect) to another page (login page) with Traefik ForwardAuth ? I'm using the following docker labels: 'traefik.http.routers.my-route.rule=Host("main.int")' 'traefik.http.routers.my-route.entrypoints=https443' 'traefik.http.routers.my-route.tls=true' 'traefik.http.routers.my-route.middlewares=my-test-auth@docker 'traefik.http.middlewares.my-test-auth.forwardauth.address=https://auth.page.int/login/' 'traefik.http.middlewares.my-test-auth.forwardauth.tls.insecureSkipVerify=true' Traefik logs shows that is accessing the auth.page.int/login page: GET /accounts/login/ HTTP/2.0" 200 3459 but browser stays on the main page. BTW redirect works with RedirectRegex middleware for the same example. Documentation: https://doc.traefik.io/traefik/middlewares/overview/
