Django Ajax to trigger a view not working
I'm trying to trigger a view by clicking a html button in a template. template (test.html) <div id="test_count"></div> <input type="button" value="Get number of records in DB" onclick="numberec()" /> <script> function numberec() { $.ajaxSetup( {data: {csrfmiddlewaretoken: '{{ csrf_token }}'}, }); $.ajax({ type: "POST", url: "../number_of_rec/", success: function (data) { $("#test_count").html({{number_of_rec}}); } }) } </script> View.py def number_of_rec(request): number_of_rec = Record.objects.count() data2 = render(request, 'test.html', {'number_of_rec': number_of_rec}) return (data2) def test(request): return render(request, 'test.html') urls.py from django.urls import path from . import views urlpatterns = [ path('', views.home, name='home'), path('number_of_rec/', views.number_of_rec, name='number_of_rec'), path('test/', views.test,name='test'), ] When I go to https://my_web_app.com/test in the web browser, the button doesn't trigger the number_of_rec view and the div is not filled with the result. BUT if I trigger the view by going to https://my_web_app.com/number_of_rec in web browser, the button is working and fill the div with the expected result. What should I do for my Ajax to trigger the number_of_rec view from the test.html page or any other page ? I'm a bit lost ... Thanks -
Rotation of the sphere in the photo with CSS
I want this hemisphere in the photo related to Wikipedia to rotate inward with only HTML and CSS codes (like the movement of the earth). The code that I sent below rotates the entire image, and it is also a 360-degree rotation, not an inward rotation. <img src="{% static "wiki.jpg"%}" alt="wiki.jpg"> img{ border-radius: 100px; margin-top: 400px; } @keyframes img { 0%{ transform: rotate(0deg); } 100%{ transform: rotate(360deg); } } img{ animation: img 20s ease-in-out infinite; } IMAGE If it is not possible to do this with this image, how can I design a similar image? -

How to do mobile notifications with Django backend and flutter frontend? [closed]
I have a Flutter front-end mobile (iOS) app with a Django backend. I have a feature where I create posts and tag people. So when a creator publishes the post, the data is stored in the backend, Django. And also reflects on the tagged people's homepages when they reopen or refresh their app. Now I am planning to add a notification system in the app, where the post publishing should also alert the tagged people with a notification that they have been tagged. With a quick google seems like there are 2 ways to do it and I am confused about which one is feasible: Approach 1: When the creator publishes the post, have a concurrent command to send FCM notifications to the invited mobiles. Here, I won't be dealing with the backend at all. This ‘frontend-originating’ notifications seem easy as I don't have to deal with backend Django at all. Approach 2: Once the data is stored in the backend, send a django-fcm notification to alert the devices. This seems like a robust solution, as I think, in the future, IF I add backend computations and want to alert the user, I will have a ‘backend-originating’ notification already set … -

Connecting Django Application in One Docker Container to MySQL in Another Container
Title: "Connecting Django Application in One Docker Container to MySQL in Another Container" I have a setup with two Docker containers: mysql-container: This container runs a MySQL image. my-django-container: It hosts a functional Django application. My objective is to establish a connection between the Django application running in my-django-container and the MySQL server in mysql-container. However, I'm encountering a database connection error: django.db.utils.OperationalError: (2002, "Can't connect to server on '36.253.8.13' (115)") Here are my Django settings for the database: "default": { "ENGINE": "django.db.backends.mysql", "NAME": "name", "USER": "username", "PASSWORD": "password", "HOST": "172.18.0.2", # What should I put here? The actual IP of the server `36.253.8.13` or the IP of the SQL container `172.18.0.2`?

How to use or work with fileshare.aio library?
I have been trying to implement the azure.storage.fileshare.aio Python SDK to upload files to my Azure File Share. I tried using the asyncio class and its functions to implement the directory_client.upload_file() function, that seems to be not working as expected and the control directly jumps to the return statement. I have provided the code snippet below. Please excuse any of the knowledge gap regarding async implementation, I have just started off with it. def some_other_func(): ..... directory_client = get_directory_client_aio(base_url=file_dir_url) response = asyncio.run(save(directory_client, new_file_with_changes, tasks=tasks)) ..... return response async def save(directory_client, new_file_with_changes, tasks : list): async with directory_client: tasks.append(asyncio.create_task(directory_client.upload_file(file_nam=new_file_with_changes.name, data=new_file_with_changes, length=new_file_with_changes.size))) asyncio.gather(*tasks) return Response.send_response(code=55) It will be appreciated if I get some assistance, Do's and Don'ts on the same. Thank you. -
Django and React authentication with Axios failing
I am building a web app with React and Django (frontend and backend resp.) and I am struggling to do user authentication. The urls in Django in my setup are basic, I will commit them for now. The views should be straightforward (feel free to suggest a more idiomatic approach as I am struggling with getting the right request response flow) basically, you can get a user with /users/int:id/ which returns either a private or public user object depending on whether the id is also the id of the authenticated user, login sends the id of the current user when successful. The issue I have is that login on it's own works just fine, though, when I refresh the page, react seems to have forgotten that the user was logged, it would be really annoying to ask the user to log in every time the page reloads. Therefor I made the authenticate view (and url users/authenticate/) which is supposed to return the private user object based on the session id. It is at this stage that things go wrong, the view does not recognise the user as authenticated (i.e., is_authenticated would fail). Some of the react: Home.js export const Home … -

I need to know the correct directory, where I should put the .wsgi, virtualenv, app.py, static and templates. Can anyone help me, please? Follow my .wsgi: # vim: syntax=python import sys activate_this = '/home/tvconstruai/apps_wsgi/source/venv/bin/activate_this.py' with open(activate_this) as file_: exec(file_.read(), dict(__file__=activate_this)) sys.path.append('/home/tvconstruai/apps_wsgi/') from source.app import app as application KingHost has a tutorial page for hosting this type of application, but it is not in the same scenario as mine, in which it has more files and folders like "static", in addition to not being clear and explanatory.

Django async with AppConfig.ready sync/async
I am running Django version 4.2.4 in async mode. For one of my apps I have some code to run on ready like this: class CoreConfig(AppConfig): name = 'demo.core' def ready(self): from .utils import my_sync_func my_sync_func() When I run this code, I get the warning "RuntimeWarning: coroutine 'CoreConfig.ready' was never awaited" When I use sync_to_async like this: class CoreConfig(AppConfig): name = 'demo.core' async def ready(self): from .utils import my_sync_func await sync_to_async(my_sync_func)() I get the warning "RuntimeWarning: coroutine 'CoreConfig.ready' was never awaited" What is the correct way of doing this? Thanks a lot -

Change the sort order with the dash being at the end of the query param
Instead of sorting like this /product/list/?sort=-price, I wish to sort like this /product/list/?sort=price-, where the dash character is placed at the end of the field name in the query param. In my views.py: from rest_framework.filters import OrderingFilter from rest_framework.generics import ListAPIView from rest_framework.response import Response from django.db.models import F from django_filters import rest_framework as filters from app.filters import ProductFilterSet from app.models import Product from app.serializers import ProductSerializer class ProductViewSet(ListAPIView): queryset = Product.objects.all() serializer_class = ProductSerializer filter_backends = (filters.DjangoFilterBackend, OrderingFilter,) filterset_class = ProductFilterSet ordering_fields = ("date_updated", "price") def list(self, request, *args, **kwargs): queryset = self.filter_queryset(self.get_queryset()) page = self.paginate_queryset(queryset) if page is not None: serializer = self.get_serializer(page, many=True) return self.get_paginated_response(serializer.data) serializer = self.get_serializer(queryset, many=True) return Response(serializer.data) def get_queryset(self): return super().get_queryset().annotate(date_updated=F("updated")) And in filters.py: from django_filters import rest_framework as filters from app.models import Product class ProductFilterSet(filters.FilterSet): class Meta: model = Product fields = { "category_id": ["exact"], "price": ["lt", "gt"], "is_available": ["exact"], } I tried adding a custom ordering filter, like this: class CustomOrderingFilter(OrderingFilter): def remove_invalid_fields(self, queryset, fields, view, request): # Remove the dash character from the end of the field name fields = [field.rstrip('-') for field in fields] return super().remove_invalid_fields(queryset, fields, view, request) class ProductViewSet(ListAPIView): queryset = Product.objects.all() serializer_class = ProductSerializer pagination_class = … -
Send email using Django and Gmail backend
I'm struggling sending emails with a custom domain using Gmail backend. EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend" EMAIL_HOST = "smtp.gmail.com" EMAIL_HOST_USER = os.environ["EMAIL_HOST_USER"] EMAIL_HOST_PASSWORD = os.environ["EMAIL_HOST_PASSWORD"] EMAIL_PORT = 587 EMAIL_USE_TLS = True email = EmailMessage( subject, content, "myaccount@mydomain.com", [customer.email] ) email.send() I've created a Google account with the custom domain and generated an app password, but when using custom domain for EMAIL_HOST_USER, I get (535, b'5.7.8 Username and Password not accepted. Learn more at https://support.google.com/mail/?p=BadCredentials'): EMAIL_HOST_USER = os.environ["EMAIL_HOST_USER"] # myaccount@mydomain.com Then I tried with a Google account using a gmail.com domain, and this time it works: EMAIL_HOST_USER = os.environ["EMAIL_HOST_USER"] # myaccount@gmail.com So I need the sender's mail to be different than myaccount@gmail.com. I've tried to add a secondary mail address in Google, and used DEFAULT_FROM_EMAIL = "myaccount@mydomain.com" but it doesn't seem to change anything. I've also tried the solution from this post, same issue. -
Content Security Policy is set, but not detected
I have django-csp version 3.7 (https://pypi.org/project/django-csp/). It is added to the middleware section: MIDDLEWARE = [ 'csp.middleware.CSPMiddleware', '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', ] And here's my settings: CSP_DEFAULT_SRC = ["'none'"] CSP_IMG_SRC = ["'self'"] CSP_STYLE_SRC = ["'self'", "'unsafe-inline'"] CSP_STYLE_SRC_ELEM = ["'self'", "'unsafe-inline'", "https://fonts.googleapis.com"] CSP_SCRIPT_SRC_ELEM = ["'self'", "'unsafe-inline'"] CSP_FONT_SRC = ["'self'", "data:", "https://fonts.googleapis.com", "https://fonts.gstatic.com"] I know that the above settings work because first I had lots of errors in the browser console and then all gone and the site works correctly. However, two sites checking the host headers (this one and this one) both report that my site is missing Content Security Policy. What I'm missing here? -
Django- filtering on ManyToMany field with exact matches
I have the following models: class Hashtag(models.Model): title = models.CharField(...) class Annotation(models.Model): ... hashtags = models.ManyToManyField(Hashtag) I want to get the Anntoations that have all [hashtag_1, hashtag_2, hashtag_3] as their hashtag. Following is my query: annotations = Annotation.objects.filter( hashtags__title__in=["hashtag_1", "hashtag_2", "hashtag_3"] ) This queryset, returns all annotation that have at least one of ["hashtag_1", "hashtag_2", "hashtag_3"] but I want to receive the annotations that have only these 3 hashtags (not more than and not less than these hashtags). How can I do that? I also tried the following query: annotations = Annotation.objects.annotate( hashtag_count=Count("hashtags") ).filter( hashtags__title__in=["hashtag_1", "hashtag_2", "hashtag_3"], hashtag_count=3 ) if an annotation has [hashtag_1, hashtag_2, hashtag_n], this query will return it (that is not what I want)
