Django SECURE_HSTS_SECONDS preventing access
I have a Django application deployed on a Linux virtual machine using Nginx as a reverse proxy. The website used to work very well and was accessible by users via HTTPS. However, I have set SECURE_HSTS_SECONDS = 3600 in the settings.py. This blocked access to the website, resulting in a timeout and a status code of 301. I then commented out this line of code. I expected the application to be accessible by users after an hour or so, since the variable SECURE_HSTS_SECONDS was set to 3600 seconds, but it still remains unaccessible. My relevant settings are: if not DEBUG: # Production settings SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True SECURE_SSL_REDIRECT = True # SECURE_HSTS_SECONDS = 3600 # NOTICE that this line was present before but is not commented out SECURE_HSTS_PRELOAD = True SECURE_HSTS_INCLUDE_SUBDOMAINS = True Any idea as to why this might be the case? -
How would one scrape <figure> tags in bs4?
I am trying to scrape images off of https://nytimes.com, however , most of the main headlines' corresponding images on their website is stored inside a <figure> tag, not an <img> tag with a specific src attribute. How would i be able to scrape the urls for the images inside those <figure> tags so i'd then be able to aggregate them on my own website? -
django file opens locally but fails in server
What I wanted to achieve was for a user to upload a file through a form, lets say profile picture, My aim is to take that file, send it through imgbb's api and get the image url to store for use in my template later. I was able to achieve this with the piece of code below, that works locally(Windows) but as soon as I push to my production server(pythonanywhere in this case), the code fails. # CODE: def testingpage(request): image = '' url = '' if request.method == 'POST': pic = request.FILES['image'] url = upload_to_bb(request, pic) if url is not None: from django.contrib import messages messages.info(request, 'Uploaded Successfully') return render(request, 'test.html', {'image': url}) def upload_to_bb(request, pic): import os from django.conf import settings from django.core.files.storage import FileSystemStorage import base64 import requests base_url = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) fs = FileSystemStorage() filename = fs.save(pic.name, pic) file_path = f'{base_url}\media\{filename}' apikey = settings.IMGBB_API_KEY with open(file_path, "rb") as file: url = "https://api.imgbb.com/1/upload" payload = { "key": apikey, "image": base64.b64encode(file.read()), } r = requests.post(url, payload) js = r.json() if r.status_code == 200: data = js['data'] file.close() os.remove(file_path) return data['image']['url'] else: file.close() os.remove(file_path) from django.core.exceptions import ValidationError raise ValidationError("An error occurred processing the image") return None the culprit is … -
Reverse query via foreign key in Django
What query can I use to return all the Organisation objects that are members of a certain membership_id value? e.g. return all Organisation objects that have a membership_id = 101 class Organisations(model) id = models.CharField() class Memberships(model) membership_id = models.IntegerField() organisation_id = models.ForeignKey(Organisations) -
While testing a Django DRF application, how can I make the user in my tests superuser?
I currently have a Django Rest Framework application that executes different logic for superusers than regular users. I've written my tests using both rest_framework.test and pytest-django. My Tests are currently failing because of the error: TypeError: Cannot cast AnonymousUser to int. Are you trying to use it in place of User?. So because I don't have a user set (my app does not allow unauthenticated users), my code is trying to look for a profile of the user making the call and failing. Right now, I'm not looking to test the functionality of User logic. Is there a way to set the default user in test_settings.py to a superuser, or setup a superuser in the def setup(self, request) function at the start of each of my test classes? The DRF docs relating to authentication in testing seem to be geared towards testing the authentication itself as opposed to assuming authentication around other tests. Based on those docs, I think I could hack something together, but there must be a standard way of doing what I'm trying. From what I've read, I can use force_authenticate on a particular user, but it's unclear to me where that user comes from. Do I … -
How to create a table of events which are summarized daily
I have a model for user hours: class Hours(models.Model): project = models.ForeignKey(Project, related_name='project',on_delete=models.DO_NOTHING) owner = models.ForeignKey(User, related_name='owner', on_delete=models.DO_NOTHING, default=1) quantity = models.DecimalField(max_digits=10, decimal_places=2, default=1) product = models.ForeignKey(Product, related_name='product', on_delete=models.DO_NOTHING) inserted_at = models.DateTimeField(default=datetime.now, blank=True) date = models.DateTimeField(default=datetime.now, blank=True) and I want to display the hours in a django template as a table so that the hours are grouped and summed up daily.

How to filter class fields using objects.filter and the id=pk in django
Good evening I would like to ask for some assistance am trying to filter the title of a post so I can write the title into a file to track user activity. This is my code for writing in the file: ''' def cover(request,pk): text = coverposts.objects.get(id=pk) thistime = datetime.datetime.now() Name = coverposts.objects.get(title__id=pk) articlefile = open('useractivity.txt','a') articlefile.write('\n'+ str(Name) + ', '+ str(thistime)) articlefile.close() return render(request,'cover.html',{'text':text}) ''' And this is the class I wish to get information from : ''' class coverposts(models.Model): title = models.CharField(max_length=100) visual = models.ImageField(upload_to='images') subtitle = models.CharField(max_length=100) body = models.CharField(max_length=100000000) created_at = models.DateTimeField(default =datetime.now(), blank= True) ''' Kindly advise where am going wrong -
Celery Child Tasks Don't Run in Correct Queues on ECS
I have a django project that uses celery for task management and rabbitmq for the broker. The tasks are divided into multiple queues and in production these queues run in separate ECS containers. All the period tasks defined in celery.py scheduled via celery-beat run in the correct queues however when defining the queue inside a task using apply_async they always spawn in the default. 'default_task': { 'task': 'webapp.tasks.default_task', 'schedule': crontab(minute="*/1"), }, 'parent_task': { 'task': 'webapp.tasks.parent_task', 'schedule': crontab(minute="*/1"), 'options': {'queue' : 'secondary'} }, @shared_task(ignore_result=True) def parent_task(): qs = SomeModel.Objects.filter(status='in progress') task_expiration = 3600 for sm in qs: child_task.apply_async((sm.id,), expires=task_expiration, queue='secondary') I can confirm that the tasks are running just not on the specified queue which creates issues with timing due to potential noisy neighbors on the default queue container. Versions: django: 3.0.1 celery: 5.0.0 rabbitmq: 3.8.11 python: 3.8 -
Django dates calculator
this application should take a date from the user, store it in the database then count 9 days after it and show those 10 days in a list, I managed to make two views one to count the 10 days and show them in a list. The other view is to take the day from the user and store it in the database, now I want to connect both so by the end of the process I want the user to select the date then the application automatically stores the date and counts them and show the list. Models: from django.db import models from django.db.models.fields import DateField from datetime import datetime from django.db.models import CharField, Model # Create your models here class Event(models.Model): title = models.CharField(max_length=40) start = models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True) end = models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True) def __unicode__(self): return self.title class PeriodDate(models.Model): per_date = models.CharField(max_length=15) serializer: from dataclasses import fields from rest_framework import serializers from .models import PeriodDate class PeriodDateSerializer(serializers.ModelSerializer): class Meta: model = PeriodDate fields = '__all__' URLs: from django.urls import path from django.urls.resolvers import URLPattern from . import views urlpatterns = [ path('CalendarCount', views.CalendarCount, name= 'index' ), path('form', views.form), ] Views: @api_view(['GET']) def CalendarCount(request): #Taking date … -
Why does Celery task autodiscovery never trigger under Django?
I've got Celery 5.2.6 and Django 3.0.6. Everything is working except task autodiscovery under Django. If I run celery worker, the worker triggers autodiscovery, finds all my tasks, and displays them in a list as part of it's startup process. However, if I run my Django app or Django shell, this never happens. Additionally, even though the docs promise that accessing the task registry will trigger autodiscovery, it does not. I print app.tasks, I call app.tasks.keys(), and still no autodiscovery - it only shows the tasks that are built-in or were registered when the module containing them happened to be imported for other reasons. What do I need to do to trigger task autodiscovery? PS - If I try adding force=True to app.autodiscover_tasks(), it fails because the Django app registry hasn't finished loading at that time. -

Google Drive API, Python, Django
