Django ORM queryset equivalent to group by year-month?
I have an Django app and need some datavisualization and I am blocked with ORM. I have a models Orders with a field created_at and I want to present data with a diagram bar (number / year-month) in a dashboard template. So I need to aggregate/annotate data from my model but did find a complete solution. I find partial answer with TruncMonth and read about serializers but wonder if there is a simpliest solution with Django ORM possibilities... In Postgresql it would be: SELECT date_trunc('month',created_at), count(order_id) FROM "Orders" GROUP BY date_trunc('month',created_at) ORDER BY date_trunc('month',created_at); "2021-01-01 00:00:00+01" "2" "2021-02-01 00:00:00+01" "3" "2021-03-01 00:00:00+01" "3" ... example 1 "2021-01-04 07:42:03+01" 2 "2021-01-24 13:59:44+01" 3 "2021-02-06 03:29:11+01" 4 "2021-02-06 08:21:15+01" 5 "2021-02-13 10:38:36+01" 6 "2021-03-01 12:52:22+01" 7 "2021-03-06 08:04:28+01" 8 "2021-03-11 16:58:56+01" 9 "2022-03-25 21:40:10+01" 10 "2022-04-04 02:12:29+02" 11 "2022-04-13 08:24:23+02" 12 "2022-05-08 06:48:25+02" 13 "2022-05-19 15:40:12+02" 14 "2022-06-01 11:29:36+02" 15 "2022-06-05 02:15:05+02" 16 "2022-06-05 03:08:22+02" expected result [ { "year-month": "2021-01", "number" : 2 }, { "year-month": "2021-03", "number" : 3 }, { "year-month": "2021-03", "number" : 3 }, { "year-month": "2021-03", "number" : 1 }, { "year-month": "2021-04", "number" : 2 }, { "year-month": "2021-05", "number" : 3 }, { "year-month": … -

Django can you give the same user 2 usernames(with "profiles")?
I'm working on a system where the same user might have 2 profiles (ex one as an employee and one as his personal profile) and I want him to access diff parts of the app based on his profile, can he get 2 usernames and get diff permissions based on the username he signed in with? Thought of making a profile model which has a user type and a foreign key to user and then make user type and user unique together so that the user could have multiple profiles but not of the same time. and then make the username on the profile and then keep the profile in the request instead of the user, but that is making a lot of issues, one is that Django doesn't allow having no username field on the user model, so does anyone know any workaround? Or the only way is giving him multiple users??? Please I need a fast answer.... -

Django post single form to 1 model and another model twice
I have a customer form containing name, email, email2 and email3 inputs. I would like to save the form using a class based view and post name and email to Customer model and iterate thru email2 and email3 and post to AdditionalEmail model, which has a foreign key to the customer model. I got it to work using a function based view, but the code seems a bit...hacky to me and I wanted to see if someone had a better way to do this, preferably using a CBV instead of FBV.

The problematic field on value is the "is_active" I configured it in the model to be "True" as can be seen in the model. When testing with Postman … -
How to allow a user to add objects in Django admin based on the user that has logged in
I want to have an admin where any user who logs in to the admin dashboard can add the objects from their operator email only. Now, the user can add a package object from another operator email as well. I don't want a user to add objects under the email of another operator's email. My Models: class UserProfile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='profile', on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) user_type = models.CharField(max_length=1, choices=USER_TYPES, default='g') first_name = models.CharField(max_length=255, default="") def __str__(self): return self.user.email class Package(models.Model): operator = models.ForeignKey(UserProfile, on_delete=models.CASCADE) destination = models.ForeignKey(Destination, on_delete=models.CASCADE) package_name = models.CharField(max_length=255) city = models.CharField(max_length=255) My package/admin.py: class PackageAdmin(ModelAdmin): icon_name = 'explore' autocomplete_fields = ['destination'] list_display = ('package_name', 'featured', 'price', 'discounted_price', 'savings', 'fix_departure', 'rating', 'date_created',) def get_queryset(self, request): abc = super(PackageAdmin, self).get_queryset(request) if request.user.is_superuser: return abc else: operator = request.user.profile return abc.filter(operator=operator) Here in the above image we can see that a user can add an object under another operator's email as well. I dont want that. The two solutions will be: Only the current user/profile visible in operator field. Although the emails are visible, cant add the package under another operator's ema -

Django GraphQL Testing Images
I'm currently performing pytest to test my GraphQL mutations. In this case, I input a test image file to determine if it's working. The following is a sample test in which the SimpleUploadedFile object throws a not JSON serializable error. What could be the cause and how should I fix this? @pytest.mark.django_db class TestUploadImage: query = """ mutation uploadImage($input: Upload!) { uploadImage(file: $input) { __typename ... on ResponseErrors { errors { __typename code message } } ... on Output { url } } } """ file = SimpleUploadedFile( name='test_image.jpg', content=b'', content_type='image/jpeg' ) input_data = {"file": file} def test_non_authenticated_request(self, user, client, client_query): response = client_query( self.query, op_name="uploadMessageImage", input_data=self.input_data, ) # Verify that there were no unhandled exceptions content = json.loads(response.content) assert "errors" not in content # Verify that AuthenticationError is in the response data assert AuthenticationError.__name__ in str(response.content) -

How to make docker-compose django server run on local wifi network, so our iOS developer can test the API from the iPhone device?
I'm trying to serve django on our local wifi IP, so our client developer can use his iOS device to test the API. The problem is that when I run the containers, it's only accessible from my chrome browser as localhost(=chrome browser run on the same macbook that is used to run the containers) My docker-compose file: version: '3' volumes: dev_postgres_data: {} dev_postgres_data_backups: {} services: django: build: context: . dockerfile: ./compose/dev/django/Dockerfile image: apps_dev_django container_name: django depends_on: - postgres volumes: - .:/app:z env_file: - ./.envs/.dev/.django - ./.envs/.dev/.postgres ports: - "8000:8000" command: /start postgres: build: context: . dockerfile: ./compose/production/postgres/Dockerfile image: apps_production_postgres container_name: postgres volumes: - dev_postgres_data:/var/lib/postgresql/data:Z - dev_postgres_data_backups:/backups:z env_file: - ./.envs/.dev/.postgres # ports must be set to use postgres container alone ports: - "5432:5432" If I run the django server locally(=not using docker-compose)with the command python manage.py runserver 192.168.0.255:8000, the client who is using the same wifi as me can access the API. I got the 192.168.0.255 with the command ifconfig | grep "inet " | grep -v 127.0.0.1 | cut -d\ -f6(something I got after some googling). If I run ifconfig, I get, ... en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 options=400<CHANNEL_IO> ether a4:5e:60:f1:cb:5b inet6 fe80::85:51dd:e37a:5435%en0 prefixlen 64 secured scopeid 0x4 inet 192.168.0.17 netmask …
