Django filter for ManyToMany items which exist only in a specified list
I have the following: class Category(): category_group = models.ManyToManyField("CategoryGroup", blank=True, related_name="category_group") class CategoryGroup(): label = models.TextField(null=True, blank=True) categories = Category.objects.exclude(category_group__label__in=["keywords_1", "keywords_2"] I wish to exclude the categories whose group label exists in either keywords_1 or keywords_2 only. If a category group label exists in keywords_1 and keywords_3 I do not want to exclude it. What changes are needed for this query? -
Unique value in django model field
I have the following code: from django.db import models from django.contrib.auth import get_user_model User = get_user_model() class Employee(models.Model): employee = models.OneToOneField(User, on_delete=models.CASCADE) executive_head = models.BooleanField( default=False, help_text=_("e.g. Chief Executive Officer or Managing Director."), ) job_title = models.CharField(max_length=100) def __str__(self): return f"{ self.employee }" What I would like to see is that only one value should be true in the executive_head field. It should not be possible to have more than one executive head. Using unique_together in the class Meta does not work (in hindsight it should not) because the false values would then not be unique. Any ideas? -
Django ForeignKey prevent creation when parent is a child
I have the following model: class PostModel(models.Model): post = models.ForeignKey('self', on_delete=models.CASCADE, related_name='posts') I can create new posts like this: post_1 = PostModel.objects.create() Or new posts with a parent post: post_2 = PostModel.objects.create(post=post_1) I want to know if it's possible for a post to have only a parent which itself doesn't have a parent. So the following wouldn't be allowed: post_3 = PostModel.objects.create(post=post_2) # post_2 has a parent, prevent creation -
Django FileDescriptor in settings
In my Django project, I want to use the MaxMind db file to acquire information about IP-addresses. The file takes up to 90 megabytes. I expect about 50 requests per second and also the application will be hosted on the Gunicorn with 3 workers. So, Will I meet the limits if I open a file every request? with maxminddb.open_database('GeoLite2-City.mmdb') as mmdb: info = mmdb.get('152.216.7.110') return Response({'city': info.city, 'other': 'some_other_information_about_ip'}) or should I open the file in settings.py once: mmdb = maxminddb.open_database('GeoLite2-City.mmdb') and use this descriptor in my views.py ? from django.conf import settings .... info = settings.mmdb.get('152.216.7.110') return Response({'city': info.city, 'other': 'some_other_information_about_ip'}) I am concerned about several problems: If 2 workers will try to read the file simultaneously, where might be conflicts. The File descriptor will not be properly closed if the application fails. What is best practice for Django apps to keep files in memory. -
Access the files that are being sent via a PATCH request inside of Django middleware
I have written a Django middelware class that I used to access the files that are being uploaded and do some stuff. I have used rest_framework package to enable some API enpoints. When I try to do a POST request with an uploaded file, I can access that file by calling request.FILES. However, if I do a PATCH request with a file, request.FILES is empty. Instead the file is inside of the request.body as a byte stream. What do I have to do to access the file using request.FILES in a patch request? Middleware: class MyMiddleware: def __init__(self, get_response): # noqa: D107 self.get_response = get_response def __call__(self, request): if request.FILES: for key, file in request.FILES.dict().items(): # Do some stuff pass response = self.get_response(request) return response I tried to parse the request with rest_framework's MultiPartParser but no luck. Thanks in advance! -
I want to make password field in my model by the inheriting AbstractBaseUser, but it shows me the error about non-nullable iid field
It is impossible to add a non-nullable field 'id' to client without specifying a default. This is because the database needs something to populate existing rows. Please select a fix: Provide a one-off default now (will be set on all existing rows with a null value for this column) Quit and manually define a default value in models.py. models.py from django.contrib.auth.models import AbstractBaseUser from django.db import models class Client(AbstractBaseUser): username = models.CharField(max_length=200) password = models.CharField(max_length=200, default="") def __str__(self): return self.username -
Django custom database field - psycopg2.errors.SyntaxError: syntax error at or near "None"
I've created a custom fields called RelativeURLField that inherits the CharField from django.db.models.CharField. from django.db import models from django.core.validators import RegexValidator class RelativeURLField(models.CharField): default_validators = [RegexValidator( regex=r'^(http(s)?:\/\/.)?(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)', message='Enter a valid URL.', code='invalid_url' )] When replacing the URLField in the model with this custom field. I get this error psycopg2.errors.SyntaxError: syntax error at or near "None" LINE 1: ...onal_investor" ALTER COLUMN "website_url" TYPE varchar(None) This is the part that is causing the error in the migration script migrations.AlterField( model_name='institutionalinvestor', name='website_url', field=accounts.fields.RelativeURLField(blank=True, default='', null=True), ), I've tried giving the field a default value by editing the AlterField part. However, the same issue persists. -

Can't see my tables in Google Cloud SQL (PGSQL) but connection is ok
I am developing an application. Everything was going well locally, I now want to create a first postgre SQL database and connect it to django.

Primary Key varchar - no detection of model changes
PostgreSql database, Django 4. I have a problem with detecting data model changes to a migration file. I am trying to add my primary key of type varchar which has format dddddd-ddd in the model. The field definition itself looks like this : mid = models.CharField(max_length=10, primary_key=True, verbose_name='custom ID'), Unfortunately, after creating the migration file, you can't see the mid field, but there is an id. To test the correctness of the makemigrations itself, I added the phone1 field, which is already detected and has coverage in the migration. Here is my model class Report(ModelBaseClass): mid = models.CharField(max_length=10, primary_key=True, verbose_name='custom ID'), created_user = models.ForeignKey(User, on_delete=models.PROTECT, editable=False, verbose_name='Przyjmując') client = models.ForeignKey(Client, on_delete=models.PROTECT, verbose_name='Klient') email = models.EmailField(null=True, blank=True, verbose_name='E-mail') phone = models.CharField(max_length=20, null=True, blank=True, verbose_name='Telefon') phone1 = models.CharField(max_length=20, null=True, blank=True, verbose_name='Telefon') comment = models.TextField(max_length=1000, blank=True, verbose_name='Uwagi do zgłoszenia') registration_date = models.DateField(auto_now_add=True, verbose_name='Data przyjęcia') ending_date = models.DateTimeField('Data zakończenia', null=True, blank=True) And an excerpt from the migration file. migrations.CreateModel( name='Report', fields=[ ('id', models.BigAutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('created_date', models.DateTimeField(auto_now_add=True)), ('modified_date', models.DateTimeField(auto_now=True)), ('email', models.EmailField(blank=True, max_length=254, null=True, verbose_name='E-mail')), ('phone', models.CharField(blank=True, max_length=20, null=True, verbose_name='Telefon')), ('phone1', models.CharField(blank=True, max_length=20, null=True, verbose_name='Telefon')), ('comment', models.TextField(blank=True, max_length=1000, verbose_name='Uwagi do zgłoszenia')), ('registration_date', models.DateField(auto_now_add=True, verbose_name='Data przyjęcia')), ('ending_date', models.DateTimeField(blank=True, null=True, verbose_name='Data zakończenia')), ('client', models.ForeignKey(on_delete=django.db.models.deletion.PROTECT, to='organize.client', verbose_ … -

python/ Django values_list is not returning all values
I have this bit of ugly code that is producing what I want. It's working but only necessary because what I would like to do with values_list is not working. member_channels = Channel.objects.filter(Q(members=request.user) | Q(owner=request.user)).prefetch_related('members').prefetch_related('owner') members_nested = list(map(lambda channel: channel.members.all(), member_channels)) members = list(dict.fromkeys(itertools.chain(*members_nested))) owners = list(map(lambda channel: channel.owner, member_channels)) # this is all the user's who's comment's the request.user should be able to see. valid_comment_users = list(dict.fromkeys(members + owners)) What I would like to do and should work is: member_channels = Channel.objects.filter(Q(members=request.user) | Q(owner=request.user)).prefetch_related('members').prefetch_related('owner') member_ids = member_channels.values_list('members', 'owner', flat=True) valid_comment_users = AppUser.objects.filter(id__in=member_ids).distinct() The issue is that with values_list I'm not getting all the members for each Channel in the members_channels it seems like it's only returning the members that are the same in all channels, or maybe just the first member I can't tell. Any insight into why values_list isn't working for this? -

Getting user name in the access token response in Django
I have integrated google social auth in my django + react.js project. I am using the access token that I am getting from google to call this url 'http://localhost:8000/auth/convert-token'. This is giving me a json response which contains the access-token and the refresh-token. However I want to add the user name in that json response as well. I tried using request.user.username. But it is not giving me anything. I guess it is because by the time the call is made the for aforementioned URL, the request doesn't have any value for the currently logged in user. Can you suggest me any way to get the username. Following is my code. @api_view(["POST"]) def googleSignIn (request): print(request.headers.get("token")) resposnePayload = {} # token obtained from google token = request.headers.get("token") clientId = "<client-id for django app>" clientSecret = "<client-secret for django app>" url = 'http://localhost:8000/auth/convert-token' header = { "Content-Type": "application/x-www-form-urlencoded" } payload = { "grant_type": 'convert_token', "client_id" : clientId, "client_secret" :clientSecret, "backend":"google-oauth2", "token":token } result = requests.post(url,data=payload,headers = header) resopnsePayload=result.json() print("currently logged in user is ",request.user.username) return Response(resopnsePayload,status=result.status_code) -

Django: how to filter with exact same count?
Let's say I have a group of id's : [1, 2, 87] I want to get all the User who have those exact addresses, not the User that might have those addresses and more.
