How to implement preview page with files Django?
I have my News model: class News(models.Model): subject = models.CharField(max_length=30) text = models.TextField() created = models.DateTimeField(auto_now_add=True) I also have File model to store files and NewsFile model to connect models to each other: class File(models.Model): file = models.FileField( 'файл' ) class NewsFile(models.Model): file = models.ForeignKey( File, on_delete=models.CASCADE, verbose_name='файл', related_name='news_files' ) news = models.ForeignKey( News, on_delete=models.CASCADE, verbose_name='новость', related_name='files' ) Here is my news form: class MultipleFileInput(forms.ClearableFileInput): allow_multiple_selected = True class MultipleFileField(forms.FileField): def __init__(self, *args, **kwargs): kwargs.setdefault("widget", MultipleFileInput()) super().__init__(*args, **kwargs) def clean(self, data, initial=None): single_file_clean = super().clean if isinstance(data, (list, tuple)): result = [single_file_clean(d, initial) for d in data] else: result = single_file_clean(data, initial) return result class NewsForm(forms.ModelForm): files = MultipleFileField(required=False) class Meta: model = News fields = ('subject', 'text') I want to make a page with a preview of the news and buttons to publish or edit the news.

Google Authentication Not Appearing in Django Project
Body: I am trying to set up Google authentication in my Django project using django-allauth, but the Google login option is not appearing on my login page. I suspect I might be missing a configuration step or setting. I have confirmed the site ID is correct by checking the link: http://127.0.0.1:8000/admin/sites/site/3/change/ Could someone help me identify what I might be missing or doing wrong? Here are the relevant parts of my settings.py: SOCIALACCOUNT_PROVIDERS = { "google": { "app": [ { "client_id": "myid", "secret": "mysecret", }, ], "SCOPE": [ "profile", "email", ], "AUTH_PARAMS": { "access_type": "online", }, } } SITE_ID = 3 MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'allauth.account.middleware.AccountMiddleware', 'livereload.middleware.LiveReloadScript', ] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [TEMPLATES_DIR], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'core.views.site_settings', 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] LOGIN_REDIRECT_URL = 'login' # Redirect after login LOGOUT_REDIRECT_URL = 'home' # Redirect after logout -
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. -
How do I retrieve more than 10k document in elasticsearch?

Django reverse ForeignKey returns None
I have Student and Mark models in different apps of one project. # project/study # models.py class Mark(models.Model): ... student = models.ForeignKey( "students.Student", on_delete=models.PROTECT, related_name="marks", related_query_name="mark", ) # project/students # models.py class Student(models.Model): ... # views.py class StudentDetailView(DetailView): queryset = Student.objects.prefetch_related("marks") template_name = "students/one_student.html" context_object_name = "student" # one_student.html ... <p>{{ student.marks }}</p> ... Output of html is "study.Mark.None" That is my problem. I tried making ManyToOneRel field on student, select_related, making custom view func, but that does not help. Reverse ForeignKey brings None. I watched related questions - can't understand answers, because they are unrelated directly to my situation. I'm expecting to get all Student's marks. What am I doing wrong? -

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). The Certificate Authority reported these problems: Domain: example.com Type: unauthorized Detail: During secondary validation: 2a06:98c1:3120::1: Invalid response from http:// example.com/.well-known/acme-challenge/funkylettersandnumbers: 403 sudo iptables -P INPUT ACCEPT sudo iptables -P FORWARD ACCEPT sudo iptables -P OUTPUT ACCEPT sudo iptables -t nat -F sudo iptables -t mangle -F sudo iptables … -
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 … -
Why my Elasticsearch request doesn't show any hits?
I have dockerized Django project. I want to use Elasticsearch, so I choosed django-elasticsearch-dsl. My steps were: In my Django project's settings file (settings.py), I configured the Elasticsearch connection settings. ELASTICSEARCH_DSL = { 'default': { 'hosts': ["http://localhost:9200"], }, } Created a file named documents.py my Django app. In this file, I defined Elasticsearch documents that correspond to my Django models. from django_elasticsearch_dsl import Document from django_elasticsearch_dsl.registries import registry from .models import Filmwork @registry.register_document class FilmWorkDocument(Document): class Index: name = 'film' settings = {'number_of_shards': 1, 'number_of_replicas': 0} class Django: model = Filmwork fields = ['title', 'description'] So then I indexed data from my Django model into Elasticsearch by using command python3 manage.py search_index --rebuild. I used this command outside docker, it showed: File "/Users/ArtemBoss/Desktop/artem_yandex_repo/venv/lib/python3.10/site-packages/psycopg2/__init__.py", line 122, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) django.db.utils.OperationalError: could not translate host name "database" to address: nodename nor servname provided, or not known At the same time, when I'm trying to index data inside django container it shows: File "/usr/local/lib/python3.10/site-packages/elastic_transport/_node/_http_urllib3.py", line 202, in perform_request raise err from None elastic_transport.ConnectionError: Connection error caused by: ConnectionError(Connection error caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x7f9150762b60>: Failed to establish a new connection: [Errno 111] Connection refused)) Anyway Index was successfully … -

What's the best approach to keeping data consistent in a django-based app used in parallel by three or four users?
I'm making a Django app using a postgresql database for a family who need to coordinate their grocery purchases. Say one person has on their mobile device a full list of the groceries and is in the supermarket, buying and ticking each item off the list. His partner decides to stop at another shop and begins buying the items on the same list. How would you approach ensuring that they don't buy double or, more importantly, that they don't end up messing up the data entirely? A simple first-come, first-served lock, giving the second user only read-only rights? Or is there a more flexible way? And if the best way is a lock, how much does postgresql do for you? -

Django URL 404 - 1 week spent debugging with GPT4, Claude luck. One specific function is just NOT resolving
Issue Summary: I'm facing an issue where the /LS/mark-text-responses/ URL in my Django application is not being found when an AJAX request is sent to the mark_text_responses view. This issue is occurring in the user-facing part of my application, specifically in the JavaScript code that sends the AJAX request. I'm receiving a 404 Not Found error, indicating that the URL is not being resolved correctly. Relevant JavaScript Code: **javascript ** function submitWorksheet(event, activityIndex) { event.preventDefault(); const worksheetForm = event.target; const worksheetQuestionsData = worksheetForm.querySelector('.worksheet-questions').textContent; let worksheetData = {}; try { worksheetData = JSON.parse(worksheetQuestionsData); } catch (error) { console.error('Error parsing worksheet data:', error); return; } // ...

A "django.core.exceptions.SuspiciousFileOperation" error is occurring despite setting everything up correctly
Currently attempting to serve all of my static files via whitenoise. Funnily enough, the function itself works a treat. It seeks out all the directories labelled static in all of my Django apps. However, why is Django consistently returning the django.core.exceptions.SuspiciousFileOperation exception in my traceback, and why is this returning this just one css file. Logic would dictate that seeing as this css file is among other .css files in the same directory, Django seems to have some sort of personal vendetta against this one file. On the face it it, what Django is doing is completely illogical. My settings are as follows: pip install whitenoise settings.py INSTALLED_APPS = [ .... 'django.contrib.staticfiles', .... ] BASE_DIR = Path(__file__).resolve().parent.parent STATIC_URL = 'static/' STATIC_ROOT = BASE_DIR / "staticfiles" STATICFILES_DIRS = [ BASE_DIR / "static/libraries/assets/brand-assets", BASE_DIR / "static/libraries/assets/images", BASE_DIR / "static/libraries/assets/vectors", BASE_DIR / "static/libraries/assets/videos", BASE_DIR / "static/libraries/css", BASE_DIR / "static/libraries/js", BASE_DIR / "static/main", BASE_DIR / "legal/static", BASE_DIR / "blog/static", BASE_DIR / "events/static", BASE_DIR / "careers/static", BASE_DIR / "media/static", BASE_DIR / "static", ] My file directory is as follows: PROJECT NAME-| Root-| settings.py careers-| static-| careers.css media-| static-| media.css blog-| static-| blog.css legal-| static-| legal.css static-| main-| xxx.css xxx.css libraries-| css # <- location of … -

make authenticated and login work for multiple table other then auth User table django?

Unable to start Django app, error related to what seems like a circular import?

I get this error when trying to start the app. <class 'mainapp.admin.CertificateAdmin'>: (admin.E108) The value of 'list_display[3]' refers to 'is_active', which is not a callable, an attribute of 'CertificateAdmin', or an attribute or method on 'mainapp.Certificate'.

Memcached-MemcacheIllegalInputError - Data values must be binary-safe: 'ascii' codec can't encode characters in position 2-5: ordinal not in range(128
I'm doing some tests with memcached on my django project to understand if I can get benefit of it. But I stuck at unicode character caching. I read many article about it but still could not understand how can I make it work. Here is my code block: def cache(request): client = Client("127.0.0.1:11211") cache_key = '123' # needs to be unique cache_time = 86400 # time in seconds for cache to be valid data = client.get(cache_key) # returns None if no key-value pair if not data: print("setting cache") #data contains unicode characters - Throws an error datafromdb = Subject.objects.all() #unicode characters - Throws an error unicodestr="abçüıö" #encoded unicode characters - Working fine encodedunicodestr=str.encode("abçüıö") client.set(cache_key,unicodestr , cache_time) else: print("getting from cache") return HttpResponse(data) So If I use str.encode on text values It works fine and data can be cached. But If I retrieve data from database(postgres) and this data contains unicode memcached throws an error. I'm wondering if is there a way to use str.unicode on my queryset/list etc that returned from database or something else may be. -
