(Django, Ajax, FormMixin, Forms) 500 (Internal Server Error) Error submitting form
To send and receive a response I use Ajax, Django and the Based View class. I want to implement form submission via Ajax so that the page does not reload after submitting the form. To receive the form to the server I use FormMixin. I get the following error in the console 500 (Internal Server Error): views.py: import os import json from urllib import request from django.conf import settings from django.views.generic import TemplateView, ListView, DetailView from django.views.generic.edit import FormMixin from django.shortcuts import redirect from django.http import JsonResponse from mobile_template.views import MobileTemplateView from .models import Layouts from .forms import RequestPriceForm class LayoutsDetail(MobileTemplateView, FormMixin, DetailView): model = Layouts template_name = 'main/layouts_detail.html' form_class = RequestPriceForm # def get_context_data(self, **kwargs): # context = super().get_context_data(**kwargs) #context['form'] = RequestPriceForm() #try: #pet = json.load(request.urlopen('https://pets.nlk.agency', timeout=1)) #context['pet'] = pet['pet'] #context['token'] = pet['token'] #except: #context['token'] = None #context['pet'] = None #return context def get_success_url(self): return reverse('layouts_detail', kwargs={'pk': self.object.id}) def get_context_data(self, **kwargs): context = super(LayoutsDetail, self).get_context_data(**kwargs) context['form'] = RequestPriceForm() try: pet = json.load(request.urlopen('https://pets.nlk.agency', timeout=1)) context['pet'] = pet['pet'] context['token'] = pet['token'] except: context['token'] = None context['pet'] = None return context def post(self, request, *args, **kwargs): form = RequestPriceForm(request.POST) if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) def form_invalid(self, form): response = super(LayoutsDetail, … -
Django Is it possible to display images from media subfolders?
I have the project in which admin(editor) is uploading images to database and they will display in articles and articles minatures (form of a list). I managed to configure displaying images from the media folder but it is not working in the way i would it like to be. I would like to upload images in the specific subfolders of "Media" folder. e.g: blog/media/reviews_images blog/media/reviews_minatures_images I know that upload to the specific folders is possible but that is not the point of this question. I am courious how can i configure MEDIA ROOT to display images from different subfolders of it. Now I can specify one of this folders as MEDIA ROOT and the images from this folder are displaying correctly but from the other arent displaying at all. Is it possible to configure that? my code: models.py fs_reviews_images = FileSystemStorage(location="blog/media/reviews_images") class ReviewsImages(models.Model): image = models.ImageField(storage=fs_reviews_images) description = models.CharField(max_length=50) fs_reviews_minature_images = FileSystemStorage(location="blog/media/reviews_miniatures_images") class ReviewsMiniaturesImages(models.Model): miniature_image = models.ImageField(storage=fs_reviews_minature_images) description = models.CharField(max_length=50) game_title = models.CharField(max_length=50) def __str__(self): return f"{self.game_title} {self.description}" urls.py urlpatterns = [ path("admin/", admin.site.urls), path("", views.HomeView.as_view(), name="home"), path("reviews", views.ReviewsListView.as_view(), name="reviews"), path("reviews/article/<pk>", views.ReviewsDetailView.as_view(), name="reviews-detail") ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) settings.py MEDIA_ROOT = os.path.join(BASE_DIR, "blog/media/reviews_miniatures_images") MEDIA_URL = '/media/' template <img src="{{ MEDIA_URL }}{{ … -
APIView Query Not Returning Any Results
I am having one of those days where the things I think are going to be easy on this project are just not turning out that way. I feel like I must be overlooking something very simple here in my frustration... I have an APIView that passes in the a UUID to identify the "chapter" of the game story, checks to see if the current logged in user has an entry saying they completed the challenge, then if so returns the next Hunt Clue (different from the chapter challenge) or zero for me to handle in the UI. For some reason, it is not returning any results in the query. However, when I output the raw sql query (queryset.query) the query returns the results expected just fine. Any help greatly appreciated. View class GetHuntClue(APIView): def get(self, request, **kwargs): serializer_context = { 'request': request, } chapter_uuid = self.kwargs['chapter_uuid'] curr_user = self.request.user #check to make sure it's answered then provide the appropriate hunt clue. log_type = GameActivityType.objects.filter(activity_type_name="Correct Challenge Answer").first() already_ans = GameActivity.objects.filter(user=curr_user).filter(activity_chapter=chapter_uuid).filter(activity_type=log_type).count() if (already_ans): queryset = HuntClue.objects.filter(hunt_chapter=chapter_uuid) print(queryset.query) serializer = HuntClueSerializer(queryset, context=serializer_context) return Response(serializer.data) else: return HttpResponse(already_ans, content_type="text/plain") Serializer class HuntClueSerializer(serializers.ModelSerializer): class Meta: model = HuntClue #fields = '__all__' fields = ("id", … -

Display JSON data with Django/ Python and Bootstrap
I want to display data from a countries API (Json format) into a bootstrap 5 card inside a Django project. The Json file contains dictionarries and lists. I can access data to use a for loop. For example x.capital.0 displays the capital for all the countries. But the currencies is the problem because it is a nested dictionarry. I could use x.currencies.USD.name but then I have to specify the second key (USD) for every country so the I have to use 100 lines of code the do this. Is there a way to skip the second key? I tryed x.currencies.itmes(), x.currencies.values(), x.currencies[1] and much more. Could you please help to solve this problem. Many thanks in advance.

How do I make the channels for each chats using Pusher Channel
So basically I am making a social media web using Django, and I also build a chat message on my web as well, so I looked into YouTube and followed a tutorial to make a real-time chat message, and I also use the Pusher WebSocket to hold the message to be sent, but I met a problem is that when I message with the one I click on, the message is also displayed to the other user account, but it does not actually exist because when the other user reload the page, the message from me to the user I chat with disappear. The success part is that the message is displayed forever in my chat with the one I message with even if I reload the page. I spent almost a week to figure it out but any ideas I think about aren't working.

How to send multiple time series objects (created in Django view) to Dash Application for plot?
I have a Django application aiming to track my stock portfolio daily value (Time Series 1) and daily return (Time Series 2). These 2 Time Series are computed in Django based on custom models and methods. On my homepage, I want to display these Time Series in a Dash app with 2 buttons: "Returns" and "Prices".

I was able to use Django Session Authentication to pop open the google auth portal and successfully log in the user, however I now need to use this functionality from an outside source, prompting me to need to use the swagger oath.

AttributeError: '_io.BytesIO' object has no attribute 'endswith' when attempting to check audio and video codec from base64 video file in Django
I'm currently working on a Django project where I need to check the audio and video codec of a base64-encoded video file. To achieve this, I've implemented a function that decodes the base64 string into binary data and then attempts to load the video clip using MoviePy. However, I'm encountering an AttributeError: '_io.BytesIO' object has no attribute 'endswith' when trying to run the code. Here's the relevant part of the code: def get_video_codec_info(base64_data): # Decode base64 string into binary data _format, _file_str = base64_data.split(";base64,") binary_data = base64.b64decode(_file_str) # Load the video clip using MoviePy clip = VideoFileClip(BytesIO(binary_data)) # Get information about the video codec codec_info = { 'video_codec': clip.video_codec, 'audio_codec': clip.audio_codec, } return codec_info The error occurs at the line clip = VideoFileClip(BytesIO(binary_data)) and it seems related to the use of BytesIO. I've tried to find a solution, but I'm stuck at the moment. Any suggestions on how to resolve this issue or alternative approaches to check the audio and video codec of a base64-encoded video file in Django would be greatly appreciated. Thanks! -

Understanding and Fixing User Permissions Logic in Django
I know this might be a silly question but please don't laugh at me. I am struggling to understand this simple logic. I am not understating why this logic is not working where it means if request.user is not the owner of the object or the user is not an admin user. The first part of this logic works to prevent other users from overwriting the owner object but why second part not working where a user can be overwritten object if he is an admin user? if (request.user != comment.user) or (not request.user.is_superuser): why my above logic only working for if user != owner of the obj ? why admin user can't edit if he is an admin? but this logic works on both part if not (request.user.is_superuser or (request.user == blog.blog_author)): -

Session is set to None when calling an rest_framework class based endpoint
In my webpage the user will login with spotify in order to use the spotify api and display things like top songs, top artists etc. After implementing the authorization flow of spotify api, I created and endpoint that should check if the current session_id is in my database with an already assigned access token / refresh token and login the user (and generate new access token if required). The problem is inside the endpoint function, the session is None. Checking session function (here self.session.session_key is None): class IsAuthenticated(APIView): def get(self, request, format=None): # self.request.session.save() # if not request.session.session_key: # request.session.save() is_authenticated = is_spotify_authenticated(self.request.session.session_key) return Response({'is_authenticated': is_authenticated}, status=status.HTTP_200_OK) Where I make the request from (and I have the correct session): def home(request): response = get('http://127.0.0.1:8000/api/is-authenticated').json() # print(response) # print(f"{request.session.session_key=}") request.session["is_authenticated"] = response.get("is_authenticated") return render(request, "home.html") I've tried as you can see from the commented code to call .save() but it just creates a new session, it does not use the initial one -

Django rest serializer problem with serializing many-to-many field

The serializer field might be named incorrectly and not match any attribute or key on the `Dish` instance. Original exception text was: 'Dish' object has no attribute 'dish'. ChatGPT says: the problem may occur because of dish naming -
NoReverseMatch Django - Attribute printing elsewhere in file?
I am getting a 'No reverse match' error in my Django DeleteView template. I have done some research, and this is supposedly caused when an attribute for a url redirect is blank. The error looks like the following, however the success button redirect works as expected, it is only erroring on my 'cancel' option. In this case, the url thats generating this error looks like the following: <a class="mt-3 mb-3 btn btn-secondary" id="cancel-btn" href="{% url 'post-detail' object.id %}">Cancel</a> This would mean that, 'object.id' is blank/null... However, I have added this attribute into a paragraph tag within the same template, and am seeing the correct value print (in this case, 3). {% block content %} <div> <form method="POST"> {% csrf_token %} <!--required security token--> <fieldset class="form-group"> <legend class="border-bottom mb-4">Delete Event</legend> <p>Are you sure you want to delete the post "{{object.id}}"?</p> </fieldset> <div class="form-group text-center"> <button class="btn btn-danger m-3" type="submit">Yes, Delete</button> <a class="mt-3 mb-3 btn btn-secondary" id="cancel-btn" href="{% url 'post-detail' object.id %}">Cancel</a> </div> </form> </div> {% endblock content %} Perhaps I have incorrectly typed my code, but I can't seem to figure out how the value could possibly get erased and is unable to be referenced for the cancel button href?
