I have upload a django project on server in public html folder
When creating a Python application on a server, I put the folder name or project name in the application root. However, the issue is that the folder is creating outside the public HTML folder. I want the folder to be created in the public HTML folder only. How can I ensure that the folder is created in the desired location? -

React gets non responsive when data from Django is used to display a Nivo line chart
I have been trying to display a nivo line charts using data from my backend (Django). However, when the data is inserted into the nivo line chart, the react window gets unresponsive. The backend sends the timestamps and the values like this -- Example -- timestamp = "2023-05-12 16:10:53.000000000" Values -- "39.520004" class AddView(APIView): from django.views.decorators.csrf import csrf_exempt from rest_framework import status import json @staticmethod @csrf_exempt def post(request): from awsfetch.rpm import rpm timestamps, values = rpm() return Response({"timestamps": timestamps, "values": values}) This is the nivo charts component -- import { ResponsiveLine } from "@nivo/line"; const MyResponsiveLine = ({ data }) => ( <ResponsiveLine data={data} margin={{ top: 50, right: 160, bottom: 50, left: 60 }} xScale={{ format: "%Y-%m-%dT%H:%M:%S.%L%Z", type: "time" }} xFormat="time:%Y-%m-%dT%H:%M:%S.%L%Z" yScale={{ type: "linear", stacked: true, min: 0.0, max: 1.0 }} curve="monotoneX" axisTop={null} axisRight={{ tickValues: [0.0, 0.2, 0.4, 0.6, 0.8, 1.0], tickSize: 5, tickPadding: 5, tickRotation: 0, format: "0.2", legend: "", legendOffset: 0 }} axisBottom={{ tickValues: "every 1 second", tickSize: 5, tickPadding: 5, tickRotation: 0, format: "%S.%L", legend: "Time", legendOffset: 36, legendPosition: "middle" }} axisLeft={{ tickValues: [0.0, 0.2, 0.4, 0.6, 0.8, 1.0], tickSize: 5, tickPadding: 5, tickRotation: 0, format: ".2", legend: "CPU", legendOffset: -40, legendPosition: "middle" }} enableGridX={false} colors={{ scheme: … -
Django REST framework prefetch not working on model with multiple foreign keys to the same target
I'm writing an endpoint to fetch data from the "Term" model in Django REST framework and I'm trying to reduce queries by prefetching data. Specifically there is a model "TermRelation", that saves vector relation scores between individual terms that I would like to prefetch data from. Simplified, the models look as follows: models.py class Term(models.Model): term = models.CharField(max_length=255, verbose_name=_('Term'), null=True, db_index=True) class TermRelation(models.Model): src_term = models.ForeignKey(Term, on_delete=models.CASCADE, verbose_name=_('Source term'), related_name='src_term_relation') trg_term = models.ForeignKey(Term, on_delete=models.CASCADE, verbose_name=_('Target term'), related_name='trg_term_relation') vector_sim = models.FloatField(blank=True, null=True, default=0.0, verbose_name=_('Vector similarity'), help_text=_('Cosine vector similarity.')) And here's the simplified view: views.py class TermsList(generics.ListCreateAPIView): def get_queryset(self): queryset = Term.objects.prefetch_related( 'src_term_relation', 'trg_term_relation', 'note_set', 'usage_set' ).all() return queryset There are other models related to term such as "Note" and "Usage" for which prefetch is working, only for relations it still makes a bunch of queries. I've included a screenshot of the Django SQL debug results, or rather the first few lines as this goes on for a while with the same queries. You can see that Django does run the prefetch operation, but then still makes the same queries as if it didn't happen. What am I doing wrong? Could this be related to "TermRelation" having two ForeignKey fields pointing to … -
Implementation of the post filter page in django
I am trying to filter blog posts using this model: class Post(models.Model): is_podcast = models.BooleanField(default=False) category = models.ManyToManyField(Category) title = models.CharField(max_length=500) slug = models.SlugField(allow_unicode=True , unique=True , null=True , blank=True) body = RichTextUploadingField() likes_count = models.IntegerField(default=0 , help_text="amount of likes") vip_members_only = models.BooleanField(default=False) def __str__(self): return self.title And I am using this view to filter the posts: def Index_view(request , slug=None): posts = Post.objects.filter() kind = request.GET.get('type') order = request.GET.get('order') author = request.GET.get('author') search = request.GET.get('search') if slug: cat = get_object_or_404(Category , slug=slug) posts.filter(category = cat) if search != '' and search is not None: posts.filter(Q(title__icontains = search)) if kind != '' and kind is not None: if kind == 'podcast': posts.filter(is_podcast=True) if kind == 'all': pass if kind == 'post': posts.filter(is_podcast=False) con = {'posts' : posts} return render(request , 'Weblog/posts.html' , con) Here is the urls.py too: path('posts/', Index_view), re_path(r'^posts/(?P<slug>[\w-]+)/$', Index_view), When I use this URL (http://127.0.0.1:8000/blog/posts/some-slug/?search=test), I receive all the posts and the filtering does not work. What is the problem? -
how do I call a djago admin delete fuction
I am trying to use the Django admin delete function to ensure that the corresponding quantity is deleted from the associated page when the delete function is clicked. For example, I have a class called RestockModel. When I add a new Restock item, the restock quantity can be automatically added in the StockListModel. However, when I need to delete the Restock item, the quantity in StockListModel is not deleted immediately. How can I call the django admin delete function to this statement? Here is the code that how I made the quantity can be added when I create a new restock item: class restockInfo(admin.ModelAdmin): list_display = ["product", "delivery_order_no","restock_quantity", "supplier_name", "created_date"] readonly_fields = ["created_date"] search_fields = ['created_date'] def save_model(self, request, obj, form, change): product = obj.product restock_quantity = obj.restock_quantity if restock_quantity and product.quantity_in_store: if restock_quantity >= 0: obj.product.quantity_in_store = product.quantity_in_store + restock_quantity # don't forget to save stock after change quantity obj.product.save() messages.success(request, 'Successfully added!') super().save_model(request, obj, form, change) else: messages.error(request, 'Invalid Quantity, Please Try Again!!!') return restockInfo This is my restock models: class restockList(models.Model): product = models.ForeignKey("stockList", on_delete=models.CASCADE, null=True) delivery_order_no = models.CharField(max_length=255, null=True) restock_quantity = models.IntegerField(null=True) supplier_name = models.CharField(max_length=255, null=True) created_date = models.DateTimeField(auto_now_add=True, blank=True, editable=False) class Meta: db_table = "restocklist" -

White space stripped from Django Template tags in PrismJS code blocks
When I render Django template code in a prismjs block, it strips white space {{}} and {%%}. For example, pre-render, the code might be {% image self.search_image thumbnail-400x200 as img %} <img src="{{ img.url }}" alt="{{ img.title }}"> But the rendered code block will be {%image self.search_image thumbnail-400x200 as img%} <img src="{{img.url}}" alt="{{img.title}}"> It's not a case of css, the space is missing from the html. I can set the language to HTML, or even python etc, the same issue remains. Does anyone know of a way to prevent this? -
How Can I implement User Sent Message and Receive Message in Django
I am working on a Django project where I have three types of users: Landlord, Agent, and Prospect. I want the Prospect user to be able to contact the Property Owner by sending a message while on the Property Detail view, and the Property Owner to be able to reply back to the Prospect using the same view. I also want all these users to maintain an Inbox and Sent Message items. I'm struggling to figure out whether my logic is sound and how to implement the functionality using Django. Is there a library that will make user messaging within Django easier? In my code, I maintain different Models for these users with a OneToOneField and use signals for automatic profile creation upon registration. I also have a Profile Model connected through the same relationship, and Message Model. I tried passing the Property Owner ID as the Recipient ID and Property ID on url from the Property Detail view to the send_message function view, but I get the error "No 'User matches the given query'." Here are my views: def property_detail(request, property_id): user = request.user #Check if user is authenticated if not user.is_authenticated: logout(request) messages.warning(request, 'Session expired.

Annotating a value in Django using Extract and OuterRef (or F) leads to TypeError
I'm building an application where users can create posts. If the user don't post anything after some specific time of the day, the server will send a push notification to remember the user to post something. In order to create this query I planned to run a scheduled celery beat task to filter the posts created in the current day, list the user's id and use a simply exclude these IDs from the active users in order to get a queryset with the users that should be notified. The user has a timezone field, which is updated via a middleware that checks some headers frontend send, checks the user saved timezone and update it if necessary. This timezone is the result of running the tzname() method in the datetime that comes in this header. The issue is that the users are spread across multiple timezones, so I need to actually annotate the created_at field in Posts (which are saved taking in consideration the server timezone) with the User's timezone. In Django we have the Extract function that simply does exactly what I need. The issue here is that it would work perfectly if I could use a F expression or … -
What kind of security should I implement in my Django REST API if it doesn't require authentication?
It's my first time building an API and it only processes GET requests. What kind of security would be necessary for this project? Other than using the .gitignore file and making sure my database key is hidden do I need to further secure the database for production? My project uses Django, Django REST, and PostgreSQL. I haven't yet found a host I like enough to deploy to so any recommendations would be appreciated. -

How to find overlapping with a given start_time and end_time (Weekday/Hour format)
I am attempting to determine overlapping availability for a specialist based on their stored availability, which is stored as a datetime due to timezone changes, but only the weekday and time portion is used.

New to django, django server not loading home page
I started a Django project and went through the regular setup process: I used the "startproject" command to create a project named "social_clone_project", and I used "startapp" to create an app named "accounts". Then I created a "views.py" file and set up the "urls.py" file. Here's what it looks like: from django.contrib import admin from django.urls import path, include, re_path from . import views urlpatterns = [ re_path(r'^$', views.HomePage.as_view(), name='home'), path("admin/", admin.site.urls), ] Recently, I switched to Ubuntu Debian with the sublime-text editor. I'm new to the Ubuntu OS, and whenever I run the "runserver" command, the default "Congratulations!" page loads instead of my home page. I've created an "index.html" file, which is supposed to load as the home page, but it's not working. Can someone help me solve this issue? -

How to properly generate thumbnail image in Django project?

How to efficiently manage nested serializer in DRF?
This is my overrided get method inside APIView, that returns post's detail page: def get(self, request, *args, **kwargs): post_instance = self.get_object() comments = Comment.objects.detail().filter(post=post_instance, comment_to_reply=None)[:5] post_serializer = self.serializer_class(post_instance) comments_serializer = self.comment_serializer_class(comments, many=True) return Response({ 'post': post_serializer.data, 'comments': comments_serializer.data }) It creates only 13 queries in DB without duplicates, but I want to serialize comments inside PostSerializer without overriding it in APIView every time. detail() here is method inside custom manager that select_related and prefetch_related my query. This is the most important part of my PostSerializer: class PostSerializer(TaggitSerializer, serializers.ModelSerializer): author = LightUserSerializer(read_only=True) ... other fields def get_comments(self, instance): comments = Comment.objects.detail().filter(post=instance, comment_to_reply=None)[:5] comments_serializer = CommentSerializer(comments, many=True) return comments_serializer.data def to_representation(self, instance): representation = super().to_representation(instance) representation['comments'] = self.get_comments(instance) return representation It basically the same lines of code from APIView, but in serializer. I get comments inside get_comments function and include it inside Response object through to_representation. It works, but the problem is that this method creates 16 duplicating queries. 25 queries overall. If I use it like SerializerMethodField it works the same way. -

Is it possible to extend or override Wagtail views?
I'm interested in adding some functionality to my wagtail blog to automatically post to social media when a post is published. Normally, the place to do this would be in the view. I did find an app on github called wagtail_share_social but it has not been updated in 2 years, and I would rather not be reliant on a third party solution. The Wagtail documentation has notes on extending views, but they seem to be limited to extending admin views, or views used in the dashboard rather than for serving up pages to non-logged in users. Is it possible to extend or override the Wagtail views for serving non admin pages? If not, what would be the correct approach to add functionality when a page is served via Wagtail?
