django.db.utils.OperationalError: (2013, 'Lost connection to MySQL server during query') in my remote web app
I have been working on a django chatting application. The link to the site is https://aniconnect.org so you can check it out if you want to see the error in action. So I am using django-channels for websockets and the websocket connection is being opened and closed instantly. I just checked it out in my console logs.

Recursive Query with Django-CTE
I have a Tree model that i need to prefetch all the childs and user of the comments all at once: class AnalysisComment(MPTTModel, TimeStampMixin): parent = TreeForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True, related_name="children" ) user = models.ForeignKey( settings.AUTH_USER_MODEL, verbose_name=_("User"), on_delete=models.CASCADE, help_text=_("User who created the blog."), related_name="analyses_comments", ) text = models.TextField(_("Text")) analysis = models.ForeignKey( Analysis, verbose_name=_("Analysis"), related_name="comments", on_delete=models.CASCADE, ) objects = CTEManager() now this is how I'm getting the analyses with comments: def recursive_comments(cte): return ( AnalysisComment.objects.filter(level=0) .union( cte.join(AnalysisComment, parent=cte.col.id), all=True, ) ) cte = With.recursive(recursive_comments) comments = cte.join(AnalysisComment, id=cte.col.id).with_cte(cte) qs = Analysis.objects.prefetch_related( "tags", "playlists", Prefetch("comments", queryset=comments, to_attr="parent_comments"), ) and i call the childs with obj.child.all() in my serializers. now there are a lot of duplicate objects in the response. and also calls a query for each comment: -
django.urls.reverse() matching URL pattern instead of name
I am coding a Django project for a Wikipedia-like site (CS50W project 1). I have one app inside the project called encyclopedia. Inside my views.py file for this app, I have a redirect, for which I use the django.urls.reverse() function. The link to the documentation for this function can be found here. Now for the problem: If the user visits /wiki/file where file is not a valid page, then the markdown file will not be found in the entry view. And, as you can see, it is supposed to redirect you to the not found page. However, the code return HttpResponseRedirect(reverse("notfound")) loops the user back to the entry view indefinitely, instead of the user being redirected to the not found page. I have found two solutions so far: One can reorder the URL patterns so that the notfound pattern appears before the entry pattern, or a slash can be added to either of the aforementioned URL patterns. I am, however, looking for the cause of the problem. I am currently considering the possibility that the reverse() function is using the URL pattern instead of the name for some reason. urls.py file for encyclopedia: from django.urls import path from . import … -
Django usage and plugins ecosystem
Why there is a drop in use of django in the world? New plugins count, maintain of existing plugins are lacking more and more. Django is very user friendly. This is crazy, stackoverflow.com says it needs at least 220 characters. Can't a question be small than 220 characters? Crazy stuff. -
How can I make a content based movie recommendation system with Django real-time data?
I am working on a project for my school. I have a Django program where I keep information about 1 million movies in Model Movie with features like title, genre and actors. models.py class Genre(models.Model): title = models.CharField(max_length=255) class Actor(models.Model): name = models.CharField(max_length=255) class Movie(models.Model): title = models.CharField(max_length=255) genre = models.ManyToManyField(Genre) actors = models.ManyToManyField(Actors) I am trying to create a celery function to train my model once in a day at 12 AM. tasks.py @shared_task def train_and_save_video(): movie_data = Movie.objects.all().exclude(actors__isnull=True, genre__isnull=True) features = movie_data.values_list('id', 'title', 'actors__name', 'genre__title') # over to you, I think we can go with TfidfVectorizer, RandomForestClassifier using pipeline # or cosine_similarity using CountVectorizer and csr_matrix but I don't think so that, this is a good approach. I want the program to learn a little bit each time I add a new movie (concatenate a new movie object to the trained model), without making it learn from scratch with all the movies every time. Can someone explain how to do this? May be we can achieve this using signals.py or admin.py -
Running own conftest for every application
I have several applications in my project each application has its own tests: app/tests/test_block1.py test_block2.py ... And every tests folder has its own conftest.py I want to drop database for every app. I use this fixture: @pytest.fixture(scope="package") def django_db(django_db_blocker): with django_db_blocker.unblock(): call_command("sqlflush") with django_db_blocker.unblock(): call_command("migrate", "--noinput") yield None Scope function and class does not fits for me. I tried module scope and all tests outside a single file fails. I tried package scope and all tests outside a single folder fails. I tried session scope and behaviour was the same. What will be the good variant in my case? Is there any variant except writting one big conftest file instead of different conftest files for every application? -
Multiple NoReverseMatch errors at password reset Django
I'm working on Django project, still new at Django. I'm trying to follow instructions from this book but there are some changes in my project. I'm trying to create login/registration with Django, but I'm stuck with reset password section. I know that my problem is related to name spacing but cannot figure out why is that and why isn't redirecting to pages mentioned in errors.

Django models.CheckConstraint causing "TypeError: 'staticmethod' object is not callable"

Django orm filling out 3 interrelated forms on one page and passing each other last inserted id. Issue if form 2 o 3 fail. Form 1 stays fatherless
I have come across an interesting issue (probably because of my lack of knowledge): I have 3 tables (3 forms) that are interrelated. Address, property and photos. The first table or form is Address, it is populated by using a select list. So, on clicking the submit button, that first form will populate a row in Address table. Then I obtain that last id in order to pass it to form 2, properties and the properties will pass the last id inserted to photos, so the three are related by Foreign Keys. What happens in this scheme? If the Property form fails because someone enters bad input in a text field, the model will reject it and will return the user back to the form. BUT, notice that the row in table address was already inserted and it will stay there. Yes, you may say that I could include a line of code in the processing of form Properties, that if it fails, it should delete the recently address row inserted but that doesn't help me because the id sequence will not be reset in the table, it will leap to the next one leaving a gap in the id … -
Shopify Python API Pagination

How to store a loaded PIL image or just the Blob Binary Data in a Django SQLite Database temporarily?

Is there anyway I can save the image in imagefield or rather save a blob data in the database because I just want to save the image temporarily where I would delete the image after doing some image processing stuff so I do not care about the database being bloated by any data. I have viewed several instructions on how to save a pil image in django database but couldnt quite make it work. -

Creating a service layer with Django Rest Framework
I am fairly new to web-development and just studing design patterns and code architecture. Now, I am developing service layer for business logic. And here I have a dillema. One approach is to use command design pattern. Where I have a class which implements user creation and related processes (e.g. sending email, writting logs etc), also this class has one public method (entry point) and private methods, called inside the entry point. Here is the example of what I mean. class CreateUser: def _create_user(self, **data) -> User: # here perform creation of user itself, requesting repository layer ... def _send_email(self, **data) -> None: # here I send email def _write_logs(self, **data) -> None: # writing logs to a file def execute(**data): self._create_user(**data) self._send_email(**data) self._write_logs(**data) On the other hand, there is a approach where I create a common service as a class, that handles user authentication and registration and for each user action has one method: class UserService: def create_user(self, **data) -> User: # call to repository # send email # write logs def update_user(self, **data) -> User: # call to repository # write logs I don't really know what solution I should choose. I suppose that the command pattern is … -

How to check if a Django CharField is empty
I've been working on a Django database project and I need to return a value only if a CharField is not empty. class author(models.Model): name = models.CharField(max_length=255, unique=True, help_text='Article author') pronouns = models.CharField(max_length=255, help_text='Enter pronouns (optional)', blank=True, verbose_name='Pronouns (optional)') if pronouns != '': def __str__(self): return f'{self.name} ({self.pronouns})' else: def __str__(self): return self.name Despite me not entering anything in the pronouns field when testing, it still acts as if it has a value and returns Name () with nothing in those parentheses.

DRF serializer validation of inputs across multiple nested fields

For example given the unit type "length", which includes the "length" and "height" fields (units are meters, feet, etc), they need to post the same unit for both, e.g. {"length": {"value": 10, "unit": 1}, "height": {"value:15", "unit": 1}}. … -

i'm searching a way to implement django-otp and dj-stripe in a web project but i think there is a conflict because django-otp uses custom admin_site.register() to register models while dj-stripe uses admin.site.register(). i'm triyng with the following code but not works because all stripe model are registered not following list_display field customizations as in admin.py on github repository. #urls.py from django.contrib import admin from django.urls import path, include from account.admin import admin_site urlpatterns = [ path("realadmin/", admin_site.urls), path("stripe/", include("djstripe.urls", namespace="djstripe")), ] #admin.py from django_otp.admin import OTPAdminSite from django_otp.plugins.otp_totp.models import TOTPDevice from django_otp.plugins.otp_totp.admin import TOTPDeviceAdmin # Stripe modules from djstripe import models class OTPAdmin(OTPAdminSite): pass admin_site = OTPAdmin(name='OTPAdmin') # Script to register all models modelsarray = django.apps.apps.get_models() # Register other django-otp models with the custom admin site (admin_site) for model in modelsarray: try: if model.__module__.startswith("dj-stripe"): # Register with the default admin.site for dj-stripe models admin.site.register(model) elif model == Customer: admin_site.register(model, CustomerAdmin) else: # Register with the custom admin site for other models (e.g., django-otp) admin_site.register(model) except admin.sites.AlreadyRegistered: pass so, i want to register stripe's models using admin.site.register because in this way i can use admin.py code of github repository but i need also to use admin_site.register for otp secutiry tool. can … -
How to get value from select2 in Django
I am trying to add a new constraint, but according to the data, the code takes all values except acc_id4 and c_center, and the result is always something like Row 1: acc_id4=None, description=salary 10/2023, doc=1023, d_date=2023-11-25, debit=1000, credit=0.00, c_center=None I don't know why it's always nothing Is the problem in the template or in the Django code? And how do I solve this problem? Note: The JavaScript code creates a new row and makes the old row read-only. It also copies the values except for the acc_id4 and c_center values. It also makes the generated name add a number after the _ sign. html {%load static%} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Acc Entry</title> <link rel="shortcut icon" href="{% static 'image/daleel.ico'%}" > <link rel="stylesheet" href="{% static 'css\Entry.css'%}"> <!-- Font Awesome --> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.4/css/all.min.css" integrity="sha512-1ycn6IcaQQ40/MKBW2W4Rhis/DbILU74C1vSrLJxCq57o941Ym01SwNsOMqvEBFlcgUa6xLiPY/NS5R+E6ztJQ==" crossorigin="anonymous" referrerpolicy="no-referrer" /> <link rel="stylesheet" href="{% static 'plugins/fontawesome-free/css/all.css'%}"> <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Open+Sans:wght@300;400;600&display=swap" > <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons"> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <link href="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css" rel="stylesheet" /> </head> <body> <div class="radio"> <div class="btn-group" role="group" aria-label="Basic radio toggle button group"> <input type="radio" class="btn-check" name="btnradio" id="btnradio1" autocomplete="off" > <label class="btn btn-outline-primary" for="btnradio1">New</label> <input type="radio" class="btn-check" name="btnradio" id="btnradio2" value="save" autocomplete="off"> <label class="btn btn-outline-primary" for="btnradio2">Save</label> <input type="radio" class="btn-check" … -
