Celery is not consuming with two tasks together
sorry, I am a rookie to celery. I have 3 celery snippet as follows: first define the Task Class in celery_tasks.tasks.py import celery class LoggerDefine(celery.Task): name = 'message-logger' def run(self, payload): pass class PerformanceMeasureDefine(celery.Task): name = 'performance-logger' def run(self, payload, elapseTime):): pass then implement the methods in from consumers.logger import django django.setup() from log_models.models import Level_logs from django.conf import settings from common_functions.logger import * from celery_tasks.tasks import LoggerDefine, PerformanceMeasureDefine class LoggerImpl(LoggerDefine): def run(self, payload): fmt1 = 'Message body: {}' print("-------------------------------- log persistor consuming --------------------------------") Level_logs.objects.create( level=payload.get(LEVEL), date_time=payload.get(DATETIME), file_name=payload.get(FILENAME), line_number=payload.get(LINE_NUMBER), function_name=payload.get(FUNCTION), payload=payload.get(PAYLOAD), ) return fmt1.format(payload) class PerformanceMeasureImpl(PerformanceMeasureDefine): def run(self, payload, elapseTime): fmt1 = 'Message body: {}' print("-------------------------------- performance consuming --------------------------------") print("payload = ", payload) print("elapseTime = ", elapseTime) return fmt1.format(payload) finally, I instantiate them as two consumers from consumers.logger import LoggerImpl, PerformanceMeasureImpl from celery_tasks.utils import create_worker_from logger, _ = create_worker_from(LoggerImpl) logger.worker_main(["worker", "-c", "2"]) performance_measure, _ = create_worker_from(PerformanceMeasureImpl) performance_measure.worker_main(["worker", "-c", "2"]) then it is not working, I tried to comment out performance_measure and leave only logger like: from consumers.logger import LoggerImpl, PerformanceMeasureImpl from celery_tasks.utils import create_worker_from logger, _ = create_worker_from(LoggerImpl) logger.worker_main(["worker", "-c", "2"]) #performance_measure, _ = create_worker_from(PerformanceMeasureImpl) #performance_measure.worker_main(["worker", "-c", "2"]) then logger works properly. I also tried comment out logger and leave … -
Django ORM - 'annotate' and 'order_by' doesn't seem to work equivalently to 'GROUP BY' and 'ORDER BY'?
Summary: ordered_tags = tagged_items.annotate(freq=Count('tag_id')).order_by('-freq') for i in ordered_tags: print(i.tag_id, i.tag, i.freq) This does not work equivalently to GROUP BY tag_id ORDER BY COUNT(tag_id) DESC. Why? Using Django ORM, I am trying to do something like: SELECT tag_id, COUNT(tag_id) AS freq FROM taggit_taggeditem WHERE content_type_id IN ( SELECT id FROM django_content_type WHERE app_label = 'reviews' AND model IN ('problem', 'review', 'comment') ) AND ( object_id = 1 OR object_id IN ( SELECT id FROM review WHERE problem_id = 1 ) OR object_id IN ( SELECT c.id FROM comment AS c INNER JOIN review AS r ON r.id = c.review_id ) ) GROUP BY tag_id ORDER BY freq DESC; So here's what I have contrived: querydict_for_content_type_id = { 'current_app_label_query' : Q(app_label=ReviewsConfig.name), 'model_name_query' : Q(model__in=['problem', 'review', 'comment']) } # used in content_type_query query_for_content_type_id = reduce(operator.__and__, querydict_for_content_type_id.values()) # Query relevant content_type from TaggedItem model. content_type_query = Q(content_type_id__in=ContentType.objects.filter(query_for_content_type_id)) # Query relevant object_id from TaggedItem model. object_query = Q(object_id=pk) | Q(object_id__in=problem.review_set.all()) for review in problem.review_set.all(): object_query |= Q(object_id__in=review.comment_set.all()) tagged_items = TaggedItem.objects.filter(content_type_query&object_query) # JOIN Tag # tags = tagged_items.select_related('tag') # GROUP BY freq ORDER_BY freq DESC; ordered_tags = tagged_items.annotate(freq=Count('tag_id'))#.order_by('-freq') for i in ordered_tags: print(i.tag_id, i.tag, i.freq) Django ORM doesn't work as intended. Calling distinct method on ordered_tags … -
Django ManyToMany relationships not being saved in initial create, but saved on update - how to fix?
en mi archivo models.py tengo dos clases Curso y Carreras, en el primero de ellos tengo un campo que es una relacion del tipo ManyToMany con el segundo. El problema que tengo es que cuando voy a crear un objecto para el modelo Curso y hago las relaciones pertinentes estas no son guardadas en la base de datos, sin embargo cuando ese objeto que creo le quiero modificar la relacion ManyToMany es cuando si guarda en la base de datos la relacion, pero la que guarda e la introduje inicialmente cuando creaba el objeto. lo que quiero es que una vez creado el objeto esta relacion sea guardada correctamente y no se quede asi sin mas en el aire, porque de ella depende un calculo que hago posteriormente -

Connection reset by peer on file upload if JWT expires
We have a django app and it supports a file upload request. The entire upload comprises multiple requests. We are authenticating with JWT and we have logic to handle a 401 and in that case use the refresh token to get a new access token and resend the failed request. However if the token expires between 2 requests of the same upload the 401 response never makes it to the client. In the logs I found that before nginx gets the response we get this error: 2023/06/02 16:23:11 [error] 1924925#1924925: *75 readv() failed (104: Connection reset by peer) while reading upstream, client: xx.xx.xx.xx, server: example.com, request: "POST /api/upload/ HTTP/1.1", upstream: "uwsgi://unix:///bar/foo/our_app/app.sock:", host: "", referrer: "http://example.com:8082/" This causes the client to get an empty response body and the browser throws a ERR_CONTENT_LENGTH_MISMATCH error. The entire upload takes under 10 minutes and we have all the timeouts set to 100 minutes: uwsgi_read_timeout 6000; uwsgi_connect_timeout 6000; uwsgi_send_timeout 6000; send_timeout 6000; proxy_read_timeout 6000; proxy_send_timeout 6000; What is causing the socket to get closed? How can I prevent that? Are there other timeouts I could set? Any logging that I can enable to see why the socket is getting closed? Is there a way to … -
Django model: Query of query or filter of filter
I have 2 models, and on the function, I need to filter in 'x' the users which has the id's equal the id's received. And secondly, I need to filter in another query (let's say 'y'), the description from model Detail, which has the person_id equal to the id's already filtered in 'x'. It's like a filter of a filter, or a query of a query. class Person(models.Model): user = models.ForeingKey(Users, on_delete=models.CASCADE) name = models.CharField(max_length=50) class Detail(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) description = models.TextField() def test(request, id_user): x = Person.objects.filter(user_id = id_user) I don't know how to do it. I'm new to Python and Django. It would be something like this: y = Detail.objects.filter(person_id = id_x). But of course, this isn't right. Can someone help me? -

Should I use regular SQL instead of an ORM to reduce bandwith usage and fetching time?
I'm building a ethereum explorer for fun with django ORM (never used it before). here is a part of my schema : class AddressModel(models.Model): id = models.BigIntegerField(primary_key=True) first_seen = models.DateTimeField(db_index=True) addr = models.CharField(max_length=42, db_index=True, on_delete=models.PROTECT) is_contract = models.BooleanField() is_token = models.BooleanField() is_wallet = models.BooleanField() class BlockModel(models.Model): id = models.BigIntegerField(primary_key=True) number = models.BigIntegerField() status = models.CharField(max_length=20) timestamp = models.DateTimeField(db_index=True) epoch_proposal = models.IntegerField() slot_proposal = models.IntegerField() fee_recipient = models.ForeignKey(AddressModel, on_delete=models.PROTECT) block_reward = models.BigIntegerField() total_difficulty = models.CharField(max_length=100) size = models.IntegerField() gas_used = models.BigIntegerField() gas_limit = models.BigIntegerField() base_fee_per_gas = models.BigIntegerField() burnt_fee = models.BigIntegerField() extra_data = models.TextField() hash = models.CharField(max_length=66) parent_hash = models.CharField(max_length=66) state_root = models.CharField(max_length=66) withdrawal_root = models.CharField(max_length=66) Nonce = models.CharField(max_length=20) # you can do address_model_instance.transactionmodel_set.objects.all() since there is a FK in Transaction model class TransactionModel(models.Model): id = models.BigIntegerField(primary_key=True) hash = models.CharField(max_length=66) block = models.ForeignKey(BlockModel, on_delete=models.PROTECT) from_addr = models.ForeignKey('AddressModel', related_name='from_addr', on_delete=models.PROTECT) to_addr = models.ForeignKey('AddressModel', related_name='to_addr', on_delete=models.PROTECT) input = models.TextField() is_valid = models.BooleanField() What concerns me here is that if I want to retrieve every transaction related to a specific from_addr it will also retrieve the bloc data in the returned object, if the from_addr has 10K transaction that is 10K block data that I don't need. with regular SQL I would only get a … -
django-nested-admin nested model initial values
I've been working with django-nested-admin for editing admin models that have foreign key relationships to other tables. Frankly it's beautiful. I love it. But I have a pair of models here I'm having a bit of trouble with. I have a Chapter, representing a chapter of a club. Each chapter has a one or more useful links to things like their web page or wiki articles or whatever. Both classes have a field of 'registrar' which is the user that created them. Basically whoever was logged in to the system when the instance was created. For Chapter, this went fairly easily. I just added def get_changeform_initial_data(self, request): get_data = super(ChapterAdmin, self).get_changeform_initial_data(request) get_data['registrar'] = request.user.pk return get_data To the ChapterAdmin class. It pre-populates just fine. But when I tried to do the same with the UsefulLinksInline, that ChapterAdmin uses. I've been down a rabbit hole of googling and break-point surfing trying to figure out how to pre-populate the UsefulLink class's registrar field with the current user. In UsefulLinksInline, if I remove the registrar field from the fields=() list, I get an error stating that the null constraint on registrar was being violeted. If I leave it in, however, the Registrar combo … -
Where to host Django project files on deployment server
New to Django here. I have developed a minimum working django website with Postgres as database back-end and nginx/gunicorn as web server on Ubuntu linux. Currently all the files are on my laptop in ~/workspace/djangoapp/src$ in my home directory. I want to now deploy the project to GCP. Which directory, on the production server, the files would go in? It can't be my home directory on the production server. Shouldn't they go in one of the system directories like /opt? -
How to prevent auto-filling of other Django forms when updating a specific form and how to make them not required to fill?
I have some Django forms each one with an update button that I'm rendering on a template. When I try to submit something through the button I can't because It says I have to fill every form. I also run into the problem that when I try to update a form the value in the other forms changes and auto-fills. forms.py class ImageUpdateForm(forms.ModelForm): image = forms.ImageField(widget=forms.FileInput) class Meta: model = User fields = ['image', 'mnemonic'] def clean(self): super(ImageUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class PasswordUpdateForm(forms.ModelForm): class Meta: model = User fields = ['password', 'mnemonic'] def clean(self): super(PasswordUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class PinUpdateForm(forms.ModelForm): class Meta: model = User fields = ['pin', 'mnemonic'] def clean(self): super(PinUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class MnemonicUpdateForm(forms.ModelForm): class Meta: model = User fields = ['mnemonic', 'password'] def clean(self): super(MnemonicUpdateForm, self).clean() password = self.cleaned_data.get('password') if password != self.instance.password: self._errors['password'] = self.error_class([ 'The password is wrong!']) return self.cleaned_data views.py def UpdateView(request): user = request.user if request.method == 'POST': mnemonic_form = … -
Implementing Name Synchronization and Money Transfers in Transactions Model with Account Number Input
I have the following models in my Django application: class Transaction (models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_number = models.IntegerField() name = models.CharField(max_length=50) amount = models.DecimalField() created_on = models.DateTimeField() class Wallet(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_balance = models.DecimalField(default=0) class AccountNum(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_number = models.IntegerField() slug = models.SlugField(unique=True) I want to implement a feature where the name field in the Transactions model gets synchronized with the account owner's name based on the provided account_number input. Additionally, I want to enable money transfers using the current user's wallet and the specified amount in the Transactions model. To provide some context, I have a post-save signal generate_account_number which generates a random 6-digit account number and creates an AccountNum object for a newly created user. What are some recommended techniques or approaches to achieve this synchronization of the name field with the account owner's name and enable money transfers using the wallet model and specified amount in the Transaction model? -

Advice for developing a ticket selling platform for events
I'm a junior developer with little experience from Argentina. I have done courses in JavaScript, CSS, React, python, django and SQL. I want to develop a platform for selling tickets for events. In the beginning, it will be basic to show in my portfolio but I want to continue developing until it gets fully functional and advanced to be used as a real business. The platform need user registration with many profiles like “Promoters” who can create events, manage them, take statistics, “Final users” who can buy tickets from all the events already created, see all the bought tickets, transfer tickets to another users and “Sellers” who can be assigned to events by promoters to sell tickets through a personalized link (which can be traceable). When users log-in there should be a kind of a dashboard with all the functions mentioned before (and more). The home page will be basic, with cards of all the uploaded events. Before I start the project, I want to be sure that I'm using the correct technologies and that everything is scalable because like I said before the mid-term objective is that it gets real. I was thinking of using React and maybe Next.JS … -

Why does django url tag with argument work in VS Code but not Visual Studio 2019?
I have a simple django app built in Visual Studio 2019 using python. I am trying to use a url template tag to open a record in a form on another page in order to update that record but it always returns: 'reverse not found...' This is the template tag (uform.id is the argument): <td><a href="{% url 'app:form-update' uform.id %}">{{ obj.form_name }}</a></td> The url paths: from django.urls import path from app import views app_name = 'app' urlpatterns = [ path('', views.home, name='home'), path('form-create/', views.create_form, name='form_create'), path('form-update/<str:pk>/', views.updateForm, name='form-update'), ] The view: def updateForm(request, pk): uform = Forms.objects.get(id=pk) form = FormRegisterForm(instance=uform) if request.method == 'POST': form = FormRegisterForm(request.POST, instance=uform) if form.is_valid(): form.save() return redirect('app:form_register') context = {'form': form} return render(request, 'app/form_create.html', context) When I replace the id argument in the url template tag with an id such as 19, it works without error. This suggests the syntax of the url template tag is wrong, however the same syntax works in other apps I have created using VS Code. I don't understand why it won't work in Visual Studio 2019. Any help would be greatly appreciated. -
