How to get all relations for items in database model in Django
I'm trying to make an online business canvas. In this app, we have a database containing Project, User and 9 other models. All models are connected to one specific project. In the app, when user click on on of the items (which is stored previously in the database, I want to retrive all the related items to it. For example, when user click on a cost-structure, I have to bring everything which is related to that cost-structure or if user click on one value-proposition, I have to bring everything which is connected to that value-proposition. below is the database model: from django.db import models from django.contrib.auth.models import AbstractUser class User(AbstractUser): pass class Project(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=255) def __str__(self): return self.name def get_all_relationships(self): relationships = { 'value_propositions': self.value_propositions.all(), 'customer_segments': self.customer_segments.all(), 'channels': self.channel.all(), 'customer_relationships': self.customer_relationship.all(), 'revenue_streams': self.revenue_stream.all(), 'key_resources': self.key_resources.all(), 'key_activities': self.key_activity.all(), 'key_partners': self.key_partner.all(), 'cost_structures': self.cost_structure.all(), } return relationships class ValueProposition(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name="value_propositions") value = models.CharField(max_length=255) description = models.CharField(max_length=1023) def __str__(self): return self.value class CustomerSegment(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name="customer_segments") value_propositions = models.ManyToManyField(ValueProposition, related_name="customer_segments") customer_segment = models.CharField(max_length=255) def __str__(self): return self.customer_segment class Channel(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name="channel") customer_segment = models.ManyToManyField(CustomerSegment, related_name="channel") channels = models.CharField(max_length=255) def … -

Django async - OperationalError: the connection is closed - does not recover after db restart
I have something like the following coroutine, running by an async task: from django.db import OperationalError from my_app.models import User async def update_user_name(user: User): while True: try: user.name = coolname.generate_slug() await user.asave(update_fields=["name"]) except OperationalError: logging.exception( "DB operational error occurred, Wait 2 seconds and try again." ) await asyncio.sleep(10) when the db is inaccessible I'm getting OperationalError which makes sense. But then after fixing the db I keep getting those OperationalErrors and the connection does not really recovers I wonder why? I would expect a new connection to be opened and to be able to save to db since the issue was fixed. Im using Django 5.0.4 I noticed that my CONN_MAX_AGE db setting was 5 minutes. I changed it to 0 (close connection after each request) and it didn't help. -

Django hidden field obligatory field error
I'm developing a Django page where a user fills out a lottery form. This data is stored in a MySQL database. Part of the functionality of the page is that the user can retrieve the form with the lottery data already entered to add more, modify some, or rerun the lottery without needing to re-enter all the data. Now, for this purpose, I have these forms that I am using to retrieve the lottery, add participants, add lottery data, etc... class SorteoForm(forms.ModelForm): class Meta: model = Sorteo fields = ['organizer', 'celebration_date', 'budget'] class ExclusionForm(forms.Form): participants_to_exclude = forms.CharField(label='Participants to exclude', max_length=100) class SorteoRecuperadorForm(forms.Form): recuperator_lottery = forms.CharField(label='Lottery code', max_length=50, required=False) class ParticipanteExclusionForm(forms.Form): name = forms.CharField(label='', max_length=100, widget=forms.TextInput(attrs={'placeholder': 'Name'})) email = forms.EmailField(label='', max_length=100, widget=forms.EmailInput(attrs={'placeholder': 'Email'})) exclusions = forms.CharField(label='', max_length=100, required=False, widget=forms.TextInput(attrs={'placeholder': 'Exclusions'})) ParticipanteExclusionFormSet = formset_factory(ParticipanteExclusionForm) ParticipanteFormSet = formset_factory(ParticipanteForm) ExclusionFormSet = formset_factory(ExclusionForm) The data control for these forms, both to rerun the lottery and to retrieve the data, is done through this method: def recover_lottery(request): lottery_form = SorteoForm(request.POST or None) ParticipanteExclusionFormSet = formset_factory(ParticipanteExclusionForm, extra=0) participant_formset = ParticipanteExclusionFormSet(request.POST or None, prefix='participant') recuperator_form = SorteoRecuperadorForm(request.POST or None) lottery = None participants = None if request.method == 'POST': if recuperator_form.is_valid(): # Retrieve the lottery and participants lottery … -
Comments asigned correctly to answer objects but display in one answer objects
I'm building a question-and-answer platform to help companies understand their customers' needs. As you can see in the view_question views, I'm displaying an answer based on the question, and it is working perfectly. However, when displaying comments on the answer using this method: answers = Answer.objects.filter(post=question) answers_comment = CommentA.objects.filter(post=answers) This method return an error in the template saying: The QuerySet value for an exact lookup must be limited to one result using slicing. then i try to display it using this method: answers = Answer.objects.filter(post=question) answers_comment = CommentA.objects.filter(post__id__in=answers) It seems like the problem is solved, but it is not. The answers_comment display all comment objects to a single answer object, even though they were not assigned to that answer. {% for answer in answers %} <div class="row border-bottom"> <div class="col col-answer"> <div class="answer-icons"> <a style="text-decoration: none;" href=""> <span><i class="fas fa-arrow-up"></i></span> <span>{{ answer.up_vote }}</span> </a> <a style="text-decoration: none;" href=""> <span><i class="fas fa-arrow-down"></i></span> <span>{{ answer.down_vote }}</span> </a> </div> <div class="answer-text"> <p>{{answer.your_answer|convert_markdown|safe}}</p> </div> </div> </div> {% endfor %} <div class="comment-container m-2"> {% for answer_comment in answers_comment %} <div class="row"> <small>{{ answer_comment.comment }}</small> {% with answer_comment.user.account as account %} <a style="text-decoration: none;" class="user-avatar" href="{% url 'Public-Profile' slug=account.slug %}"> <span>{{ answer_comment.user.username }} </span> </a> <small>{{ … -

Django : Locally save an instance of a Model
Using signals, I try to track the difference between the old instance of an object and the new instance when the Model is saved. I tried this : But logically in the model_post_init_handler method, it's a reference of the object that is stored in __original_instance. So, instance.__original_instance.is_used and instance.is_used will always be the same. How could I store a "snapshot" of the object when he is initiated, so that I will be able to track what is edited ? -
Integrating Microsoft Forms Authentication in Python Django: Troubleshooting Terminal Error
To integrate the Microsoft Forms authentication flow into my Python Django project for accessing various forms URLs and storing form details and responses, I'm employing the provided MS Forms authentication code within my project's backend. Additionally, I've configured my project to run within a Docker container.

How do I write tests for my django-extensions cron job?
I have a cron job in my Django app that's defined as a MinutelyJob (from django-extensions). How do I write tests for the job? The module documentation is quite sparse, and doesn't tell me how to call the job from code as opposed to the command line. I don't want to write test code that depends on undocumented interfaces. Alternatively, should I reimplement the job using a different module? I only have the one job so Celery is a bit heavyweight for my use case. -
How can I customize Django Rest Framework documentation without using decorators?
I'm currently working on a Django project and utilizing Django Rest Framework (DRF) for building APIs. I've integrated drf-pectacular for automatic API documentation generation, but I'm finding that using decorators to customize the documentation is making my codebase messy. I'm interested in exploring alternative approaches to customize my DRF documentation without relying heavily on decorators. Could someone provide guidance on how to achieve this? I'm specifically looking for methods or techniques that allow me to customize the documentation while keeping my code clean and maintainable. Any suggestions, examples, or best practices would be greatly appreciated. Thank you! -
How to Handle and Send Various File Types (Images, Videos, Audios, PDFs, Documents) in a Django Chat App Using WebSockets and Django REST Framework
I'm working on a chat application where I need to handle and store various types of files such as images, videos, audios, PDFs, and documents using Django and Django REST framework. I have a WebSocket consumer with events like connect, disconnect, and receive. In the receive event, I'm trying to handle video files.

What changes do I need to make in my code to handle video files properly and send them over the WebSocket? Additionally, I'm looking for a solution that allows me to handle and send other file types like images, audios, PDFs, and documents as well. -

Speeding up Django's total record count calculation for a site with 20 million records MySQL
I've encountered a problem with my Django website. Given that my database contains more than 20 million records, the operation of counting the total number of data (count) becomes extremely slow. I am using the following queries: company_count_query = f"SELECT COUNT(DISTINCT cs.OGRN) AS total_companies {company_from_clause} WHERE {company_match_condition} {email_condition} {capital_condition} {date_condition} {company_okved_condition}" ip_count_query = f"SELECT COUNT(DISTINCT ip.OGRNIP) AS total_ips {ip_from_clause} WHERE {ip_match_condition} {imail_condition} {ip_okved_condition}" How can I optimize these queries or use other methods to speed up the calculation of the total number of records? Thank you for your help! I tried to optimize the query structure by adding indexes to the columns on which filtering is performed, hoping to improve the performance of the counting operation. I expected that this would reduce the query execution time and speed up the data processing. However, in practice, the query execution time remained high and the counting operation still takes too long. -

403 Error when renewing Let's Encrypt Certbot using Django and Apache. I have 6 days to renew
When running the certbot renew command I first change my firewall permissions to allow connections on port 80, I put Cloudflare into Development Mode, then I run the renewal command. However this time I received a 403 Forbidden error trying to access the url example.com/.well-known/acme-challenge/funnylettersandstuff. I don't remember certbot needing this url but I only do this once a year for just one of my websites because for whatever reason I never got this configuration to auto renew. So here I am now trying to figure out what is causing this error. I have reviewed my virtual host configuration file and I cannot see any reasons this could be occuring. I also have modsecurity enabled but I doubt that's the issue since I cannot find any related errors in the modsecurity logs. Do I need to do something to Django to make this work? Certbot failed to authenticate some domains (authenticator: apache).

Python Celery route task using hostname
I'm currently utilizing Celery for task management within my application, and I'm facing a challenge regarding task distribution to specific workers based on their unique hostnames. In my use case, I'm deploying multiple worker containers for a particular application. These containers are required to connect to various VPNs for specific requests or processing tasks. The challenge arises from the dynamic nature of container deployment, where each container's hostname is unique and dynamically assigned and it is stored on database with metadata information to be used by the application to select which worker should run a particular task. Given this scenario, I'm seeking a solution to send tasks directly to a specific worker based on it's hostname. This would ensure efficient task distribution, even in dynamic deployment environments where workers may connect to different VPNs dynamically and have different hostname each time. The logic to select the worker is already in place. The logic to create container/worker is already in place. The logic to requeue a task that is sorted to an invalid queue is already in place. Scenario Workers Worker01 (hostname=a333) connected to VPN 1 Worker02 (hostname=b999) connected to VPN 2 Worker03 (hostname=c777) connected to VPN 3 Worker04 (hostname=c444) connected …
