Polling a Celery Task with Ajax
I have a Celery task that populates a PostgreSQL database over the course of a few minutes. I want to retrieve the current data from the database in a Django view and send it to a template where it will be constantly re-displayed according to the progress of the task. So, I want to update the template in real-time. Currently, I have a view that calls the Celery task and gets the result of the task. It then renders the template and sends it the result of the task in the form of a string, as well as the id of the task. I am not very familiar with AJAX, but from what I've read I will need another view that AJAX will call to retrieve the most up-to-date result of the task. Here is the code so far: View that renders the template: def dashboard(request): result = prepare_database.delay() result_str = result.get() return render(request, 'appname/template.html', {'task_id': result.task_id(), 'str': result_str}) View that gets the current data def current_data(request): task_id = request.GET.get('task_id') if task_id: async_result = AsyncResult(task_id) return JsonResponse({'data': async_result.get()}) Ajax to poll the task (again, very new to AJAX): $.ajax({ url: '/current_data/', method: 'GET', data: { data: 'data' }, success: function(response) … -

Strange issue using CryptoJS, encrypts fine but decrypts just shows a blank file
I'm creating a browser based Django app that allows a user to upload some files to encrypt and then to decrypt using a password. I have managed to get the encryption part working but when decrypting the files all return blank. I've read through the CryptoJS docs and searched around but can't find a solution that works. I'm sure this is just a minor mistake on my behalf but would really appreciate the help.

Django Daphne – Database connections max out + "took too long to shut down"
I'm implementing a messaging system, but experiencing the following two errors on the dev server: "Application instance <...> took too long to shut down and was killed." The database connections get increased on every new EventSource that is created, despite it being closed on the frontend. Here is my code: Backend: @transaction.non_atomic_requests async def stream_chat_messages(request: HttpRequest) -> StreamingHttpResponse: async def event_stream(): SLEEP_INTERVAL = 0.3 """ We use this function to send a continuous stream of data to the connected clients.

unknown redirect problem while using django view functions
"My URL configuration code: path("get_attendance/", staff_views.get_attendance, name="get_attendance") I placed the get_attendance method in the staff_views.py file. When a user accesses the page with a staff role and makes a POST request to /get_attendance/, it returns a status code of 200, which is normal. However, when a user accesses the page with an admin role and makes a POST request to /get_attendance/, it returns a status code of 302 for a redirection response, and then the user is redirected to the /admin/home/ page." I tried placing the method in two different routes to simulate requests, but the result is still the same. When the user is staff, it returns normally, but when the user is admin, it still redirects without any response But when I moved the get_attendance method into the views.py file, both staff and admin users can now receive a response without redirection. -

Saving a search history on django project?
I'm working on Django project, and I have created search option. Now I'm interested to see if I can save what users are searching and I can used that to create new content. Also, I'd like to see that on admin side. First, this is my current setup, I have views, forms and html parts. views.py def search(request): form = SearchForm() query = None results = [] if 'query' in request.GET: form = SearchForm(request.GET) if form.is_valid(): query = form.cleaned_data['query'] search_vector = SearchVector('title', weight='A') + SearchVector('body', weight='B') search_query = SearchQuery(query) results = Lesson.published.annotate(search=search_vector,rank=SearchRank(search_vector, search_query)).filter(rank__gte=0.3).order_by('-rank') context = {'page_title':page_title, 'form': form, 'query': query, 'results': results} return render(request, 'pages/search.html', context) forms.py class SearchForm(forms.Form): query = forms.CharField() In order to save, I have tried to do following.

Django application to manage a small Inventory

Getting 'QuerySet' object has no attribute 'append' when making a function that automatically add a certain value from a ManyToManyField in Django
I am making a dictionary, and one of the features is to detect any input that is similar in the Censorships model. The reason for that is to give a tag for vulgar words. This is my Word model the tag is also in the same file, model.py. `class Word(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) # Attributes of the model word = models.CharField(max_length=120) # Tags for searching and label tags = models.ManyToManyField('Tag', blank=True, related_name="word_tag") class Tag(models.Model): name = models.CharField(max_length=50)` My forms.py looks like this, it contains forms for both word and tag model. `class RawWordForm(forms.Form): word = forms.CharField(widget=forms.TextInput(attrs={"placeholder": "Enter a word"})) tags = forms.ModelMultipleChoiceField( queryset=Tag.objects.all(), widget=forms.CheckboxSelectMultiple ) user = forms.ModelChoiceField(queryset=User.objects.all(), widget=forms.HiddenInput) class RawTagForm(forms.Form): name = forms.CharField(widget=forms.TextInput(attrs={"placeholder": "Enter a tag"}))` Now the censorship occurs in the views.py where the word will be inputted. I made sure the word is saved first and then have the tags be set because the ModelMultipleChoiceField doesn't allow tags to be retrieved through cleaned_data. `from .forms import RawWordForm, RawTagForm from .models import Word, Tag from database.models import Censorship def word_create(request): form = RawWordForm() if request.method == "POST": form_data = { 'word': request.POST.get('word'), 'tags': request.POST.getlist('tags'), 'user': request.user, } form = RawWordForm(form_data) if form.is_valid(): # Word save w = … -

Neovim unable to detect Django packages: Getting 'Unable to import 'django.*' error
I've recently configured Neovim for my development workflow, but I'm encountering an issue with Django packages not being detected properly. Whenever I try to import any Django package or use Django functions within Neovim, I receive an error message like this: Unable to import 'django.conf' I've ensured that Django is properly installed and working outside of Neovim, but within Neovim, it seems to have trouble locating the Django packages. I've checked my Neovim configuration and paths, but I'm not sure where the problem lies. Has anyone encountered a similar issue with Neovim and Django packages? How can I troubleshoot and resolve this problem to get Neovim to properly detect Django packages? Any help or suggestions would be greatly appreciated. Thank you! -
How to log in an user coming from an external link into django application
I have a Django application using the out-of-the-box Django authentication system. I need to make an integration with another web app. The users in the other web app will click a button that should take them to my web application and give them access. The other web app will send me the user's email and other data. I should create the user if it doesn't exist without asking for any credentials. I'm not sure what approach I should take. I want something simple but not too insecure. Is SSO or OAuth the way to go? I think this is generally used to sign in with Google or Facebook, etc, but in this case, we don't want to depend on Google/Facebook accounts, the users use business emails. I'm thinking of having the third-party app use a secret key to encrypt an API Token, when the user clicks the button on their app, they will send a redirect to my app with the user data and the encrypted token. I will use the secret key to validate the Token and give the user access. I want guidance on what approach is more convenient, the responsibilities of each app, and how to implement … -

Reducing docker image size: multistage build or other suggestions
I am trying to deploy my Django app with docker. This is my original docker file FROM python:3.10.5-slim ENV DockerHOME = /app WORKDIR $DockerHOME COPY requirements.txt . RUN pip install --upgrade pip COPY . $DockerHOME RUN pip install --nocache-dir -r requirements.txt EXPOSE 8000 CMD ["python", "manage.py", "runserver"] After it build however, the image size was 300MB which was too big. I then tried doing a multi stage build as follow (which according to google can help reduce the image size significantly): FROM python:3.10.5-slim as base ENV DockerHOME = /app WORKDIR $DockerHOME COPY requirements.txt . RUN pip install --upgrade pip RUN pip install --nocache-dir -r requirements.txt FROM python:3.10.5-slim COPY --from=base $DockerHOME $DockerHOME COPY . $DockerHOME WORKDIR $DockerHOME EXPOSE 8000 CMD ["python", "manage.py", "runserver"] But this also resulted in an image that was 300MB. Could someone help me with this? I have 2 questions: Is the multistage Dockerfile logical? I feel that there is something wrong which would explain why there was no significant reduction in the image size. Are there any other ways to reduce the image size? I was originally using 'FROM python:3.10.5' instead of 'FROM python:3.10.5-slim' and that gave me 600MB image size. I changed to slim and it … -

Need help addressing cors issue on server
I have a django backend with react frontend. I am trying to deploy my application on cpanel hosting. I have created subdomain for backend (api.example.com/) and main domain (example.com/) is for frontend. PS: mentioned fake URL. Following is what my settings.py looks like, INSTALLED_APPS = [ # Custom Installed "corsheaders", ... MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ... ALLOWED_HOSTS = [ 'www.example.com', 'example.com', 'xxx.yyy.208.227', ] # ALLOWED_HOSTS = ['*'] CORS_ORIGIN_ALLOW_ALL = False # CORS_ALLOW_CREDENTIALS = True CORS_ALLOWED_ORIGINS = [ 'https://www.example.com', 'https://example.com', 'https://xxx.yyy.208.227', ] I am seeing error as mentioned below, Access to XMLHttpRequest at 'https://api.example.com/api/products/' from origin 'https://www.example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
