how to set CSRF token in nextjs for django
Noob in need. I'm building an app that takes an image on nextjs and send its to a django backend. I'm currently stuck on this error WARNING:django.security.csrf:Forbidden (CSRF cookie not set.) The problem is I'm not sure how to set the cookies in the header request. I'm especially confused about whether to do in on the nextjs frontend or nextjs backend. I have a page.tsx (/src/app/capture/page.tsx) file loaded on /capture route. (pastebin: https://pastebin.com/cceX0CEV ) When the picture is uploaded, it is sent to the nextjs route /api/capture route ( /src/app/api/capture/route.ts). (pastebin: https://pastebin.com/8M5ezzA2 ) You can see here I already have functionality to fetch the CSRF cookie from django and I'm trying to add it to the request header but that doesn't work. Here, the file is now sent to the django backend: localhost:8000 here's the relevant django backend function in my views.py (pastebin: https://pastebin.com/PPj9NR3k ) and the relevant settings in my settings.py (pastebin: https://pastebin.com/UVyMQvYR ) I came across this but it didn't change much (you can see parts of it in my route.ts) Please, any help here will be appreciated. How do I set the cookie in the header? (previous iteration of this question here. hoping to get better luck … -
How to debug memory leak on DigitalOcean App Platform
My Django application run perfectly fine on my local machine, memory usage fluctuate between 700MB and 800MB, but when I execute the exact same code on DigitalOcean App Platform the memory usage is constantly increasing until it reach 100%. Then the application reboot. What could cause the issue and how to find the root cause ? I have tried to isolate the problem with memory_profiler and the @profile decorator, but the memory increase isn't associated with any line of my code. I track memory usage like this : total = memory_usage()[0] logger.info(f"Memory used : {total} MiB") -
Nested transaction.atomic loops with locks
With a Django 5.0.2 and PostgreSQL 14 (Azure Database Flexible Server) setup, I have this piece of code which, basically, translates to: with transaction.atomic(): objects = ObjectModel.objects.all(): for object in objects: with transaction.atomic(): another_object = AnotherObjectModel.objects.select_for_update().get(id=1000) # ... I've been having quite a few crashes in my database and this has proven to be the point where the bottleneck happens. As it's legacy code (and forgive me the blame game) and I cannot trace any documentation or testimony as to why it was implemented like this, would anyone have a point of view of how this could or could not be a cause for the crash? Please forgive me if this is not too explicit or not compliant to the forum's rules, I'll be more than happy to try to elaborate. I have not tried anything so far, I'm afraid. -
How to create a user profile for; 'RelatedObjectDoesNotExist: User has no userprofile' in Django
I need to create agents for my leads but I'm facing a challenge. When I execute my code it works, but when I want to create an agent this error pop's up. leads.models.User.userprofile.RelatedObjectDoesNotExist: User has no userprofile This is my agents apps views.py from django.views import generic from django.contrib.auth.mixins import LoginRequiredMixin from django.shortcuts import reverse from leads.models import Agent from .forms import AgentModelForm class AgentListView(LoginRequiredMixin, generic.ListView): template_name = "agents/agent_list.html" def get_queryset(self): return Agent.objects.all() class AgentCreateView(LoginRequiredMixin, generic.CreateView): template_name = "agents/agent_create.html" form_class = AgentModelForm def get_success_url(self): return reverse("agents:agent-list") def form_valid(self, form): agent = form.save(commit = False) agent.organisation = self.request.user.userprofile agent.save() return super(AgentCreateView, self).form_valid(form) The 3rd line from the bottom is what I believe brings the error message.

Django / SendGrid - Password Reset - "The from address does not match a verified Sender Identity. "
I started integrating SendGrid into a django project. The integration seems to work, as when a user registers a welcome email is sent to the user with email@domain-name.com as the from_email However, if a user request a new password, this produces a 500 error: "The from address does not match a verified Sender Identity." The sender identify is obvioulsy verified because the other email signals work. Questionning SendGrid on the question, they say that the email is blocked because its coming from webmaster@localhost. Which I find a bit odd. I am confused, where in Django this default email address could be? Here is my current settings.py for email: EMAIL_FROM = "email@domain-name.com" EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend" EMAIL_HOST = "smtp.sendgrid.net" EMAIL_HOST_USER = "apikey EMAIL_HOST_PASSWORD = config('SENDGRID_API_KEY', default='') EMAIL_PORT = 587 EMAIL_USE_TLS = True I dont have a specific view setup for password change except the following: class PasswordsChangeView(PasswordChangeView): form_class = PasswordChangingForm success_url = reverse_lazy('home') and, just in case this is an example of of the signals.py that triggers the welcome email: @receiver(post_save, sender=UserProfile) def created_user_profile(sender, instance, created, **kwargs): if created: subject = "title" message = render_to_string("main/email/welcome_email.html",{ 'username':instance.user, 'email': instance.user.email, }) from_email = settings.EMAIL_FROM print(f'from_email - {from_email} ') to_email = [instance.user.email] print(f'to_email - {to_email} … -

Questions about django rest framework for project
I'm a final year CS student and i opted to do my project using flutter and Django and MySQL. I'm making a texting app that allows users to send messages(texts and images) make audio and video calls. Being my first project in Django I'm unsure how to proceed. to give more precise questions: -should everything be an API that the flutter consumes? Im currently working on user auth and registration, should the messages (plan to use websockets/socket.io) and the calls and the other features be all made as restful API's? The project has a 3.5 months duration, i plan to spend the first month familiarizing myself with the API creation and consumption. This is my first post on this website even though i always use it for solutions so im unsure if a general question like this is valid, however im grateful for any input -

Tpye hints for mixins that reference attributes of a third-party base class
I'm trying to add type hints to a mixin class that is to be used alongside an external, third-party class. That is, the mixin relies on members of the third-party class. For example, a mixin for a Django form: # mixin_typing.py from django import forms class SuffixFormMixin: suffix: str def add_suffix(self, field_name: str) -> str: # prefix is an attribute of forms.Form return f"{self.prefix}__{field_name}__{self.suffix}" class SuffixForm(SuffixFormMixin, forms.Form): pass Understandably, mypy will complain about the add_suffix method: "SuffixFormMixin" has no attribute "prefix" IDE (PyCharm) will also throw a warning: Unresolved attribute reference 'prefix' for class 'SuffixFormMixin' Question: Is there any "easy" solution that lets the mixin understand that self contains attributes/methods of forms.Form? Here is a github issue that addresses this, but sadly didn't go anywhere: https://github.com/python/typing/issues/246 Maybe some kind of typing object or other mypy-fu that acts as a promise to the mixin class that the future "partner class" has the members that the mixin is using? Attempted solutions The suggestions I have found so far all have drawbacks: Type-hinting self to the partner class (works for mypy: ✅, doesn't work for IDE: ❌) I have seen suggestions to type hint self to the class that the mixin will later … -
Why are multiple bootstrap modals being rendered after HTMX hx-get?
I have a Django page using HTMX to populate some bootstrap styled tabs (Members, Events and Contacts). 'hx-get' is used to load the desired page content into the DOM. On the Members page, I have a button that opens a bootstrap modal form when clicked for the user to add a member. The issue is that the number of times the modal is rendered to the DOM when the button is clicked corresponds to the number of times the Members content is loaded. If the Members page is rendered twice (navigating from Members tab to Events tab, then back to Members), two modals appear in the DOM and so on. I initially thought it may be caused by the modal form also being rendered with hx-get. However, I've replaced the modal form with a basic modal on the same page and the issue persists. Why is only the modal being rendered multiple times? The members page is only being rendered once. Tabs code: <div class="container"> <div class="row"> <div class="nav flex-column nav-pills me-3 col" role="tablist" aria-orientation="vertical" id="tabs" hx-target="#tab-contents" _="on htmx:afterOnLoad take .active for event.target"> <button type="button" id="members-btn" role="tab" aria-controls="tab-contents" aria- selected="true" hx-get="{% url 'members' %}" class="nav-link active"> Members </button> <button type="button" … -

Problem with redis/celery, why do some tasks triggers an Errno 111 but others don't?
I am currently building a web app with django. I am using redis and celery to send emails for various purposes. I have a background worker checking my db for mails to send every 5s (very short for testing purposes),if it finds mails flagged as unsent, then it sends them, this part works as intended. However when I call the same method directly from one of my views (to send an email for account creation), I have an Errno 111. Here's my celery.py file: import os from celery import Celery from celery.signals import after_setup_logger import logging.config from inscriptionsIff import settings os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'inscriptionsIff.settings') app = Celery('inscriptionsIff') app.config_from_object('django.conf:settings', namespace='CELERY') @after_setup_logger.connect def setup_loggers(logger, *args, **kwargs): logging.config.dictConfig(settings.LOGGING) app.conf.beat_schedule = { 'send-emails-every-x-seconds': { 'task': 'inscriptionsIff.tasks.process_and_send_emails', 'schedule': 5, # Replace 'x' with the number of seconds }, } app.autodiscover_tasks() Here's my tasks.py file: from celery import shared_task from django.core.mail import send_mail from .models import Submission from django.urls import reverse from django.contrib.sites.shortcuts import get_current_site import hashlib from django.conf import settings @shared_task def send_email_task(email, subject, message): send_mail( subject, message, 'yourgmailaddress@gmail.com', [email], fail_silently=False, ) def hash_input(input_to_hash): # Use Django's SECRET_KEY to add a layer of unpredictability to the hash salted_id = str(input_to_hash) + settings.SECRET_KEY return hashlib.sha256(salted_id.encode()).hexdigest() @shared_task def process_and_send_emails(): … -

Errno 111 Connection refused: Issue with rendering PDF with xhtml2pdf in Django on a Linux server with static files images
I've successfully deployed my Django project on a Linux server, but I'm encountering an issue when trying to print PDF reports. The images located in the static folder are causing errors during the rendering process. <img class="logo" src="http://{{host}}/static/logo_1.jpeg"> enter image description here It's worth noting that I can access these images through their respective URLs, but I'm getting a connection refused error with xhtml2pdf. I'm curious if there might be some Apache2 configuration settings that I may have overlooked that could be causing this connection issue in the context of xhtml2pdf. Any insights or guidance on potential Apache2 configurations would be greatly appreciated. My goal is to determine if there's any permission or configuration issue with Django URLs that I might have overlooked. What doesn't make much sense to me is that I can view the images through the URL, but they can't be rendered in a PDF. Does this library use a different type of connection when importing images for PDF rendering?
