Python Django custom 404 page not working
I have essentially tried 2 solutions here. The first one: Created 404.html inside root templates directory which was supposed to be recognized by django. By the way have defined it in settings.py: 'DIRS': [BASE_DIR / 'templates'], The second solution i have tried: In urls.py: from django.conf.urls import handler404 handler404 = 'pdfapp.views.not_found' in views.py: def not_found(request, exception): return render(request, 'partials/not_found.html', status = 404) None of these solutions have worked. Neither youtube videos nor the other forms could help my case. -

It displays a table with reports and I would like to display additional information according to the report, how can I do this? e.g. a table with the details of the report is displayed, and in the browser I want to display additional information, displaying the report itself works, but when I add additional information to the code, an error appears models.py class Submissions(models.Model): submissions_number_id = models.CharField(max_length=10,blank=True, unique=True, default=create_new_ref_number,editable=False) contents = models.TextField() class AdditionalInfo(models.Model): submission = models.ForeignKey(Submissions, on_delete=models.CASCADE, related_name='additional_info', default='') contents = models.TextField() I tried this but I get an error views.py def Schedule(request): date = datetime.date.today() report=Submissions.objects.filter(execution_date=date) info=AdditionalInfo.objects.filter(submission=report) context={ 'date':date, 'report':report, 'info':info, } return render(request, 'staff/work_schedule.html', context) html <tbody> {% for qs in report %} <tr style="font-size: 10px;text-align: center;"> <th style="width: 8%;">{{qs.client.user.get_full_name}}, tel.: {{qs.client.phone_number}}</th> <th style="width: 8%;">{{qs.client.post_code}} {{qs.client.city}}, ul.{{qs.client.street}}</th> <th style="width: 40%;">{{qs.contents}}</th> <th style="width: 40%;">{{info.contents}}</th> </tr> {% endfor %} </tbody> -
Why aren't the environment variables working inside my Django Docker container?
I'm encountering an issue where Django doesn't seem to be reading environment variables when running in a Docker-compose environment. Strangely, the environment variables work fine for PostgreSQL but not for Django. I've tried both the env_file and environment options in my Docker-compose file, and I've also experimented with django-dotenv without success. Here's a snippet of my code: print(f" {os.environ.get('SECRET_KEY')} {os.environ.get('DEBUG')} {os.environ.get('DATABASE_NAME')} ") # The above print statement outputs None for all environment variables SECRET_KEY = os.environ.get("SECRET_KEY") # ... version: '3.9' services: db: # ... web: build: ./src command: gunicorn myapp.wsgi:application --access-logfile /logs/gunicorn/access.log --error-logfile /logs/gunicorn/error.log --bind 0.0.0.0:8000 volumes: # ... # env_file: #not working # - .env environment: - SECRET_KEY=${SECRET_KEY} - DATABASE_NAME=${DATABASE_NAME} # ...

How do I add fields to the django_rest_auth response object?
I am extending the default django rest auth Login class in order to add 2 fields to the response object; the user's subscription and email addresses. from dj_rest_auth.serializers import LoginSerializer class CustomLoginSerializer(LoginSerializer): subscription = SubscriptionSerializer(read_only=True) email_addresses = EmailAddressSerializer(read_only=True, many=True) class Meta: model = User # fields = ['pk', 'username', 'email'] fields = ['pk', 'username', 'email', 'subscription', 'email_addresses'] def to_representation(self, instance): print('instance: ' + instance) data = super(CustomLoginSerializer, self).to_representation(instance) data['subscription'] = instance.user.subscription data['email_addresses'] = instance.user.email_addresses.all() data['lol'] = 'lmao' return data This is the response object.

Skipping a step in a WizardView based on data entered in that step
I'm trying to build a formtools Wizard where a confirmation form is shown in one of the steps. The confirmation form is only show in specific cases (e.g. if a user has previously ordered the same item before), and it should no longer be shown after the user has confirmed. Basically, my code looks like this: def ask_confirmation(wizard): # Database conditions go here return user.has_ordered_same_item_before class ItemWizard(SessionWizardView): condition_dict = { "confirm": ask_confirmation, } ... Obviously, the step where the user is asked to confirm is never passed, because the condition is always True. I don't want to store the user's response in the database, it's just something that the wizard needs to "remember" and that I can check in the condition function. How can I test whether the user has confirmed and skip the form once they did? -

Signin Fails With Custom Errors
Signin is working flawlessly but, Signup returns with {"non_field_errors": ["Incorrect creds"]} Which I have specified in LoginSerializer. I think it's happening due to authenticate function but, I am not able to pinpoint the issue as when I print it, it returns None. Does anybody knows what could be the issue?

Value error on custom log filter when importing unrelated module

Stream Zeros with Django with StreamingHttpResponse
I have to send an amount of Zeros as response, defined by the request. They have to be plain zeros. (I know, a rather odd task...) so, for example, you need 100mb of zeros, you query ?size=100&unit=mb, you will get a stream of 100mb only zeros. Since it can be up to 16gb of zeros, I do not want to generate them at first, rather generate a stream of zeros and send this "line by line". This is what I came up with, but it does not behave like I want because it first gathers the full data and then sends it. class CreateImageAndResponseView(View): line_count = 0 def get(self, request): size_str = request.GET.get('size', '') unit = request.GET.get('unit', '').lower() if unit not in ('gb', 'mb'): return HttpResponse(status=400) try: size = float(size_str) if unit == 'gb': size_bytes = int(size * 1024**3) else: size_bytes = int(size * 1024**2) except ValueError: return HttpResponse(status=400) self.line_count = size_bytes // 1024 return StreamingHttpResponse((b'0' * 1024 for _ in range(0, self.line_count)), content_type='application/octet-stream',) I already saw Problem with Django StreamingHttpResponse, but I do not know which middleware could block this. Also, I am not running nginx or apache, just django from my console. -

How can I fix the metaclass conflict in django-rest-framework Serializer
I've written the following code in django and DRF: class ServiceModelMetaClass(serializers.SerializerMetaclass, type): SERVICE_MODELS = { "email": EmailSubscriber, "push": PushSubscriber } def __call__(cls, *args, **kwargs): service = kwargs.get("data", {}).get("service") cls.Meta.subscriber_model = cls.SERVICE_MODELS.get(service) return super().__call__(*args, **kwargs) class InterListsActionsSerializer(serializers.Serializer, metaclass=ServiceModelMetaClass): source_list_id = serializers.IntegerField() target_list_id = serializers.IntegerField() subscriber_ids = serializers.IntegerField(many=True, required=False) account_id = serializers.CharField() service = serializers.ChoiceField(choices=("email", "push")) class Meta: subscriber_model: Model = None def move(self): model = self.Meta.subscriber_model # Rest of the method code. The purpose of this code is that this serializer might need doing operation on different models based on the service that the user wants to use. So I wrote this metaclass to prevent writing duplicate code and simply change the subscriber_model based on user's needs. Now as you might know, serializers.Serializer uses a metaclass by its own, serializers.SerializerMetaclass. This results in the following error: TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases. I tried making my ServiceModelMetaClass metaclass to inherit from serializers.SerializerMetaclass but it gave me this error: File "/project-root/segment_management/serializers/subscriber_list.py", line 33, in <module> class InterListsActionsSerializer(serializers.Serializer, metaclass=ServiceModelMetaClass): File "/project-root/segment_management/serializers/subscriber_list.py", line 36, in InterListsActionsSerializer subscriber_ids = serializers.IntegerField(many=True, required=False) File "/project-root/.venv/lib/python3.10/site-packages/rest_framework/fields.py", line 894, in __init__ super().__init__(**kwargs) TypeError: Field.__init__() … -

The task in Celery is being passed from Celery Beats to Workers, and is being received there but the task is not being executed. I am using Django
Pretty much the title. The task is being passed and received properly but isn't getting executed. So I just kept a simple print statement, it still didn't execute. What I did notice was, in the admin interface, the task is being set as type 'custom' instead of 'registered' although it has same name as that of the registered task I am trying to execute. Am I missing something? Celery config in settings.py celery.py tasks.py Django admin interface.
