Django php bridge
I have configured my app like this: client -> server(Apache -> php -> [django]) Some requests are handled by the php, and some are "forwarded" to django. I can successfully access the django app via this php proxy. But when I try to upload a file to the server (here django should handle that request), is there any way to directly forward the file content to the django app or I need to temporarily save it in the php server and make a request to the django app for the rest? -
Bootstrap Modal - Deleting a Review using Django
I'm using a simple Boostrap modal and it works fine. I have a delete URL which will delete the review based on the id. My issue is, I don't know how to pass the review.id from the button, through to the modal confirm delete button.

Can I create a single endpoint for authorization and registration?
I have an interesting problem that I can't cope with, I wrote an api to register a basic django user to which his profile is attached and which does not have anything special at all, now I need this api to perform 2 functions, that is, the user enters his username , mail and password, and the system should check if there is such a user? If there is no such user in the database, then register him otherwise, authorize and return tokens, here is my code: class UserSerializer(serializers.ModelSerializer): password = serializers.CharField(write_only=True) email = serializers.CharField(write_only=True) is_active = serializers.BooleanField(default=False, read_only=True) refresh_token = serializers.SerializerMethodField() access_token = serializers.SerializerMethodField() class Meta: model = User fields = ('id', 'username', 'password', 'email', 'is_active', 'refresh_token', 'access_token') def create(self, validated_data): password = validated_data.pop('password') email = validated_data.pop('email') is_active = validated_data.pop('is_active', True) username = validated_data.get('username') user = User.objects.create_user(username=username, email=email, password=password, is_active=is_active) profile, created = UserProfile.objects.get_or_create(user=user) return user def get_refresh_token(self, user): refresh = RefreshToken.for_user(user) return str(refresh) def get_access_token(self, user): refresh = RefreshToken.for_user(user) return str(refresh.access_token) maybe someone knows how to add an authorization mechanism to it? -

Cannot make ForeignKey optional...?
In my django application, I defined a model: class CourtOrder(models.Model): category = models.ForeignKey(CourtOrderCategory, blank=True, null=True,on_delete=models.PROTECT) institution = models.ForeignKey(Institution, blank=True, null=True, on_delete=models.PROTECT) The class contains a number of other entries, but I'm having trouble with these two. I already read this post: How to make the foreign key field optional in Django model? But did not have any success, the debugger still tells me that my form is invalid if these values are not set. I ran python manage.py makemigrations and python manage.py migrate several times and I also tried to change the on_deletevalue to SET_NULLto see if my mistake was there, but that did not change the outcome.

Django query hangs on a model with a ManyToManyField to "self", when adding to prefetch_related
I have an Offer model with a self-referential ManyToManyField: class Offer(models.Model): title = models.CharField(max_length=255) priority = models.PositiveIntegerField(default=100, help_text="The highest priority offers are applied first.") cannot_combine_with = models.ManyToManyField( "self", blank=True, help_text="Never combine this offer with these offers (only the highest priority offer is applied).", ) This query works fine: >>> Offer.objects.all() This also works perfectly fine: >>> Offer.objects.prefetch_related("cannot_combine_with").all() But as soon as I add a model manager, then Offer.objects.all() no longer completes, it just hangs. class OfferManager(models.Manager): def get_queryset(self): return ( super() .get_queryset() .prefetch_related("cannot_combine_with") ) class Offer(models.Model): _base_manager = OfferManager objects = OfferManager() # ... original fields With this manager in place I can't fetch any Offer models anymore as the query just hangs. Why is it that adding prefetch_related to the OfferManager makes the query hang, while manually adding this condition (without using a custom manager) works fine? -
How to pre-populate Username field with Django

Get function in django rest framework does not work even though i explicitly say for permission to allow any

ALLOWED_HOSTS and CORS_ALLOWED_ORIGINS don't work on VPS
I have project on VPS with front-end (Angular) and back-end (Django, DRF). VPS is running on Ubuntu 22.04 and has nginx. I used docker with compose to build images and run containers. Docker works fine on VPS and if I try to get to ip-address:8081 or <domain_name:8081> I see my Angular page and other links. But if try to get port 8082 (this is where back-end is listening, see the docker-compose below) I see error DisallowedHost at /, Invalid HTTP_HOST header: 'ip-address'. You may need to add 'ip-address' to ALLOWED_HOSTS. I added everything that I found from other topics. For now I have smth like that in settings.py: ALLOWED_HOSTS = ['localhost', 'ip:8082', '127.0.0.1', 'domain_name:8082', '*',] CORS_ALLOWED_ORIGINS = [ 'http://localhost:8081', # This is to allow requests from Angular app ] but it doesn't work even when I try to rebuild images, containers and volumes. I think that's the reason why Angular can't connect to django and daphne (websocket, channels). P.S. it works locally in docker and without. If the problem can be related to CORS_ALLOWED_ORIGINS, write about it too. I don't use nginx as proxy, request filter. docker-compose.yml: version: "3" services: # Back-end django: build: context: ./back-end dockerfile: ./Dockerfile image: django-image … -

In short, the task is this: The database contains a table with questionnaires (field name, field question) and a table associated with the name of the question: the type of question validation (validation of number, name, mailbox, etc.), as well as a table with the user associated with the answer to the questionnaire. questionnaires and types DBdiagram My task is to create a kind of processor for filling out questions from these questionnaires. The difficulty is that, in fact, I could create a StateGroup and write it like this: class QuestionsStates(StatesGroup): email = State() phone_number = State() full_name = State() # . . .` Next, I would create handlers for each state, and after receiving and validating the data in the last state, the handlers would send the data to the database and that’s all. @router.message(QuestionsStates.last_state) async def send_data_to_backend(message: Message, state: FSMContext): user_answers = await state.get_data() # user_answer.get('') # send all data with user_id to backend … -
web_1 | Error: dictionary changed size during iteration
I have a Django Project. I have dockerized this project to run as container. Currently when I run this container using following command it shows following error at the end and exited docker-compose -f docker-compose-stag-prod.yaml up -d Docker Logs Output web_1 | Starting Gunicorn server... web_1 | 2023-12-05 18:20:18 [1] [INFO] Starting gunicorn 0.17.4 web_1 | 2023-12-05 18:20:18 [1] [INFO] Listening at: http://0.0.0.0:8000 (1) web_1 | 2023-12-05 18:20:18 [1] [INFO] Using worker: sync web_1 | /usr/local/lib/python3.10/os.py:1030: RuntimeWarning: line buffering (buffering=1) isn't supported in binary mode, the default buffer size will be used web_1 | return io.open(fd, mode, buffering, encoding, *args, **kwargs) web_1 | 2023-12-05 18:20:18 [6] [INFO] Booting worker with pid: 6 web_1 | 2023-12-05 18:20:18 [7] [INFO] Booting worker with pid: 7 web_1 | 2023-12-05 18:20:18 [8] [INFO] Booting worker with pid: 8 web_1 | 2023-12-05 18:20:18 [9] [INFO] Booting worker with pid: 9 web_1 | web_1 | Error: dictionary changed size during iteration I am not able to identify the line which is causing error.

Postgresql causing memory problems in django
I recently started getting this error Python(43052,0x7000021e4000) malloc: *** error for object 0x1: pointer being freed was not allocated Python(43052,0x7000021e4000) malloc: *** set a breakpoint in malloc_error_break to debug on launching my local Django server. I know Python has nothing to do with malloc which is a C library, and this kind of leaves me powerless, as I don't really know C... Shouldn't python do all this automatically? I figured that when I disconnect my PostgreSQL database (i.e. just comment out the DATABASES= ... ) in my settings.py the error goes away. It of course doesn't run my project as it relies on the database, but at least the error happens within the app. If I bring back the DATABASES, Django doesn't even start the app, as the error happens right on server startup and is only logged in the console. What's interesting is that the very same version of the program, but deployed to my production server on Azure works perfectly.
