Can't create migrations with Django
I'm trying to create migrations for my pet project. However, I'm experiencing an Error that can't google an answer for: it says: `vincent@master-PC:/media/vincent/82944C77944C6FA9/Users/Ghost/Desktop/Python/PB/lesson 40/meeting_planner$ python3 manage.py makemigrations Traceback (most recent call last): File "/media/vincent/82944C77944C6FA9/Users/Ghost/Desktop/Python/PB/lesson 40/meeting_planner/manage.py", line 22, in <module> main() File "/media/vincent/82944C77944C6FA9/Users/Ghost/Desktop/Python/PB/lesson 40/meeting_planner/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/home/vincent/.local/share/virtualenvs/lesson_40-49hQCJIK/lib/python3.10/site-packages/django/core/management/__init__.py", line 446, in execute_from_command_line utility.execute() File "/home/vincent/.local/share/virtualenvs/lesson_40-49hQCJIK/lib/python3.10/site-packages/django/core/management/__init__.py", line 420, in execute django.setup() File "/home/vincent/.local/share/virtualenvs/lesson_40-49hQCJIK/lib/python3.10/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/home/vincent/.local/share/virtualenvs/lesson_40-49hQCJIK/lib/python3.10/site-packages/django/apps/registry.py", line 91, in populate app_config = AppConfig.create(entry) File "/home/vincent/.local/share/virtualenvs/lesson_40-49hQCJIK/lib/python3.10/site-packages/django/apps/config.py", line 193, in create import_module(entry) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked ModuleNotFoundError: No module named 'django.contrib.cont enttypes' P.S.

how to access the Django view with the @login_required decorator?
I am puzzled as to how to access the view associated with login_required decorator. I am trying to use the requests library. Here is the relevant code: view: @login_required def user_list(request): users = User.objects.filter(is_active=True) serializer = ContactSerializer(users) return Response(serializer.data) urls: path('', views.dashboard, name='dashboard'), path('', include('django.contrib.auth.urls')) path('users/', views.user_list, name='user_list') settings: LOGIN_REDIRECT_URL = 'dashboard' LOGIN_URL = 'login' LOGOUT_URL = 'logout' For example, I am trying to access the view like this right now and I can't do it: import requests response = requests.get(url, auth = HTTPBasicAuth('user', 'pass')) where user and pass are the username and password respectively. And where url is: 'http://127.0.0.1:8000/api/users/' I get the following error: django.urls.exceptions.NoReverseMatch: Reverse for 'login' not found. 'login' is not a valid view function or pattern name. [11/Jan/2023 04:24:11] "GET /api/users/ HTTP/1.1" 500 71617 -
Django rest framework: All fields for a model not visible in the browseable interface
I am trying to learn django rest framework by making a simple CRUD expense tracker app. I want to add expenses from the DRF browse-able interface. All the fields required for adding the expense are not visible in the browse-able interface, which then is not allowing me to add new expense objects. My serializers file: from rest_framework import serializers from .models import Expense, Category class ExpenseSerializer(serializers.ModelSerializer): created_by = serializers.ReadOnlyField(source='created_by.username') category = serializers.ReadOnlyField(source='category.name') class Meta: model = Expense fields = ['created_by', 'amount', 'category', 'created_at', 'updated_at'] class CategorySerializer(serializers.ModelSerializer): created_by = serializers.ReadOnlyField(source='created_by.username') class Meta: model = Category fields = ['created_by', 'name', 'description', 'created_at', 'updated_at'] My models: from django.db import models # Create your models here. class Category(models.Model): created_by = models.ForeignKey('auth.User', related_name='category', on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) name = models.CharField(max_length=256, null=False, blank=False) description = models.CharField(max_length=256, null=False, blank=False) # maybe add bill photo option here class Expense(models.Model): created_by = models.ForeignKey('auth.User', related_name='expense', on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) category = models.ForeignKey(Category, on_delete=models.CASCADE, null=False, blank=False) amount = models.DecimalField(decimal_places=2, null=False, blank=False, default=0.00, max_digits=10) And my views: from django.shortcuts import render from expenses.models import Category, Expense from expenses.serializers import CategorySerializer, ExpenseSerializer from rest_framework import generics from rest_framework import permissions from .permissions import IsOwnerOrReadOnly # Create your … -

How to set task_id in forhand to query the task state later on?

Boto3: faster S3 Bucket Tag matching possible?
Target: Get all S3 buckets tagged with owner=dotslashshawn Firstly, I'd like to say any help will be greatly appreciated. I have working code allowing me to do this but there doesn't seem to be a way, unlike with EC2 and RDS resources, that will allow me to pull only buckets where that tag exists. I have to pull all buckets and then loop through each to get their tags, then make the comparison unless I've missed something. It takes 12 seconds to do this operation and I'm thinking, there must be a faster way. I'm keeping in mind that it'll only get slower the more buckets that are found. Question: Is this something I could speed up using parallel processing? I have cross account permissions set up because I'm looking in 5 separate accounts for matches. Example Code: accounts = [ '123', # Account 1 '456', # Account 2 '789', # Account 3 '987', # Account 4 '654', # Account 5 ] s3_data = [] owner = 'dotslashshawn' # Loop through roles for account in accounts: # Assume each role assumed_role = sts.assume_role( RoleArn= f'arn:aws:iam::{account}:role/custom-role', RoleSessionName="DotSlashShawnSession" ) # Assign credentials assumed_role_credentials = assumed_role['Credentials'] client = boto3.client('s3', aws_access_key_id=assumed_role_credentials['AccessKeyId'], aws_secret_access_key=assumed_role_credentials['SecretAccessKey'], aws_session_token=assumed_role_credentials['SessionToken'], region_name … -

Best way to make Django API call take longer
I have a Django application with an functional view API endpoint that returns a response fairly quickly. I would like to make this request intentionally take longer to return, for the purpose of avoiding DDoS attacks. I know it's possible to use throttling through DRF, but I was wondering what would be the best way to make the actual request take longer. Maybe add in a few expensive hashing functions? -
Merge Django models into a view
I am attempting to merge and pull data from three Django models into a view. Players and Events relate to each other in the Details model (a player can attend many events) using models.ForeignKey. In other platforms I would have written a DB View to join tables and the application would query that view. From what I understand Django does not support data views within Models. Looking for help on how I would approach this in Django. class Players(models.Model): firstName = models.CharField(max_length=255) lastName = models.CharField(max_length=255) highSchool = models.CharField(max_length=255) gradYear = models.IntegerField() slug = models.SlugField(default="", null=False) class Events(models.Model): title = models.CharField(max_length=255) location = models.CharField(max_length=255) date = models.DateField() class Details(models.Model): event = models.ForeignKey(Events, on_delete=models.CASCADE) player = models.ForeignKey(Players, on_delete=models.CASCADE) height = models.IntegerField(default=None, blank=True) weight = models.IntegerField(default=None, blank=True) def playerdetail(request,slug): playerinfo = Details.objects.get(id=1) template = loader.get_template('playerdetail.html') context = { 'playerinfo': playerinfo, } return HttpResponse(template.render(context, request)) -

Use Django ORM in locust
I'm using locust to load test my Django application. I'm currently hardcoding certain values in my locustfile.py: GROUP_UUID = "6790f1e6-64f9-4707-aa82-d4edd64c9cc7" @task def get_single_group(self): self.client.get(f"/api/groups/{GROUP_UUID}/") This obviously fails if GROUP_UUID is not in the database, which occurs whenever I reseed my database so I'm constantly having to change these hardcoded values. It would be much better if I could dynamically fetch a group at runtime: from myapp.models import Group @task def get_single_group(self): group = Group.objects.first() self.client.get(f"/api/groups/{group.id}/") However, I'm getting the following error, which makes sense because locust doesn't know anything about Django: ModuleNotFoundError: No module named 'myapp' Is there anyway to use the Django ORM in locustfile.py or do I need to continue hardcoding data all over the place? -
Apache error "Truncated or oversized response headers received from daemon process" when using Django

Can't import value from .env file / Django
I got a file .env with 4 values to hide sensitive data: DATABASE_PASSWD=Password1 SECRET_KEY=Password2 VAR3=Password3 VAR4=Password4 All of above values are properly imported in Django code except the DATABASE_PASSWORD. When the DATABASES configuration is as follows: # settings.py from decouple import config # ... DB_PASSWORD=config('DATABASE_PASSWD') SECRET_KEY=config('SECRET_KEY') VAR3=config('VAR3') VAR4=config('VAR4') DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': "database_name", 'USER': "database_test_admin", 'PASSWORD': DB_PASSWORD, 'HOST': "localhost", 'PORT': "5432", } } The django outputs: raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option)) decouple.UndefinedValueError: DATABASE_PASSWD not found. Declare it as envvar or define a default value. If I hardcode password that is just the same in .env the problem is gone - the password is correct since it's my private project. Other variables works well with the same config('VAR#') function in views for example. I have no clue what could be wrong here. -
