Django AJAX call to refresh table data instead of using "append"
I want to refresh the data in my table every 10 seconds, without reloading the whole page again and again So I wrote some code in AJAX to append the new data But I want to refresh the data in the existing table and am not sure how to do that My current HTML code is just appending the whole table again and again, but I just want to refresh the data in a single table <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>temp1</title> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> </head> <body> <h1>Hello there</h1> <h1>{{info_data}}</h1> <table id="_appendHere" class="table table-striped table-condensed"> <tr> <th>Username</th> <th>Email</th> <th>Gender</th> </tr> {% for item in info_data %} <tr><td>{{item.username}} - {{item.email}} - {{item.gender}}</td></tr> {% endfor %} </table> </body> <script> var append_increment = 0; setInterval(function() { $.ajax({ type: "GET", url: {% url 'App1:tempPage' %}, // URL to your view that serves new info data: {'append_increment': append_increment} }) .done(function(response) { $('#_appendHere').append(response); append_increment += 10; }); }, 10000) </script> </html> Any help would be highly appreciated!!

How to implement authentication with Azure Directory when using React Frontend and Django REST API backend?
I'm just now learning Django REST Framework. However, I've been put on a project in charge of the DRF API. The project has a React frontend connected to a DRF API backend. I've made basic JWT Auth on the DRF API side before. However, we've been tasked with using Azure Directory for authentication. My question is how would this be setup? Would the Azure Directory auth be implemented on the frontend? What should be passed back and forth from the DRF API? I'm just a little confused reading the documentation and what needs to be stored for login and sessions on the API vs the frontend. Any information would be helpful, whether it would be specifics or the general apparatus. -

Django how to sort and paginate nested ORM and non-ORM object
I need to make a query to get some properties and with its category FK get data for monthly cost in another table. With the result, need to calc value by day, installments, total price and due date. all works fine but there is a need to order data by some fields of the Property model, order by total price and paginate the result. i could make both, order and paginate work, but not together. Also, i'd like to ask if those calcs with installments is right to be placed on serializer.py, or should be moved to the viewset.py, or somewhere else? Here is my code so far: ViewSet.py with pagination: class MyViewSet(viewsets.ModelViewSet): queryset = MyModel.Property.objects.filter(status)\ .prefetch_related('owner__user')\ .prefetch_related('host__user')\ .prefetch_related('category__user') serializer_class = MySerializer pagination_class = StandardResultsSetPagination filterset_class = MyFilterSet filter_backends = [filters.OrderingFilter, dj_filters.DjangoFilterBackend] def get_queryset(self): today = str(datetime.now()) start_date = self.request.query_params.get('start_date') end_date = self.request.query_params.get('end_date') ''' validate start_date and end_date ''' return self.queryset ViewSet.py with sort: class MyViewSet(viewsets.ModelViewSet): queryset = MyModel.Property.objects.filter(status)\ .prefetch_related('owner__user')\ .prefetch_related('host__user')\ .prefetch_related('category__user') serializer_class = MySerializer # pagination_class = StandardResultsSetPagination filterset_class = MyFilterSet filter_backends = [filters.OrderingFilter, dj_filters.DjangoFilterBackend] def get_queryset(self): today = str(datetime.now()) start_date = self.request.query_params.get('start_date') end_date = self.request.query_params.get('end_date') ''' validate start_date and end_date ''' return self.queryset def list(self, request, *args, **kwargs): … -
Celery ForkPoolWorker returns None
I use Celery in my Django app. If I've understood correctly, Celery has two processes, MainProcess and ForkPoolWorker. The latter one is asynchronous and is used to do the heavy lifting to not block the main process. In my project, it seems like the MainProcess does the job and ForkPoolWorker logs None. Every time it runs a scheduled task, I get two loggins: [2022-01-28 02:13:35,597: INFO/MainProcess] Task my_task[0b0f3301-1a98-41f3-b635-a660c0779281] received [2022-01-28 02:13:35,706: INFO/ForkPoolWorker-2] Task my_task[0b0f3301-1a98-41f3-b635-a660c0779281] succeeded in 0.10891842400087626s: None I assume it returns None because the ForkPoolWorker doesn't do anything. Is it an automatic process or do I need to activate it somehow? Or does it kick in if I at some point have lots of tasks to process? At the moment I only have one task, is it the reason why the main process is used and if so, is there something I'd need to do to my setup? -

How to convert Django Management Commands into Form Actions to populate database with an uploaded CSV file?
Django 1.9.8, Python 3.6, Postgres database I am writing a small Django app that will use the UI to import products from an uploaded csv file via a Form and populate the database. I have written the backend logic for the app using Custom Management Commands but am struggling confused about how to connect this to the frontend using Forms. Here's an example of the csv file: name,sku,description Brian James,skus-will-look-like-this,The products will have various descriptions. And multiple lines too. I have the following logic implemented: Read a large csv file of 500K products to the database using SKU as a unique field. When the file has uploaded, a live stream of what is happening should be displayed. print() currently serves this purpose but I think it should be possible to implement this with SSE on the front end. All products can be searched / filtered. Be able to delete all existing records and start a fresh upload as well as being able to add/update products manually. I created a simple form uploader as a separate project to play around with it, but even after this and reading the docs I am not clear on how to make the jump from … -
Get submit input in Django without forms
I have a page with several buttons, and only some appear depending on the scenario. More specifically, I have a user profile page that gives the user various buttons depending on their relationship to the user that they are viewing. I determine which buttons to display by identifying the user's relationship with the user they are viewing, then use a series of if statements in the profile page to display the right buttons. For example, when the user is viewing a stranger, they have block and send friend request options. If they are viewing someone that is their friend, they have an unfriend and block option. The backend needs to know that the user pressed the submit button, so that it can update the database. Using forms for this seems excessive, since I just need a simple submit input to reach the backend(no other user data). I am showing what I'm currently using below, but for some reason, it refuses to send a POST request at all. Profile Template <h1>{{viewingName}}</h1> <img src="{{displayed_user.profile_picture.url}}" width="240"> <p>{{displayed_user.bio}}</p> {% if areFriends %} <p>You're viewing your friend</p> <input type="submit" value="Remove Friendship" name ="remove_friends_form"> <input type="submit" value="Block" name ="block_form"> {% elif activeRequestTo %} <p>Friend Request Delivered. … -
Mongoengine: create a QuerySet from a MongoDB cursor object received from aggregate

DRF Non-field errors: Unable to log in with provided credentials
I am struggling to understand why my app suddenly wont allow me to log in a user after any changes are made to their profile. I have a nested User serializer with the profile serializer fields (onetoOne) using Djoser for the urls. When I try to update the user profile from the api endpoint it updates but throws an error that the avatar has no file associated to it. I thought that if I added "required=False" to to the ProfileSerializer it would negate this behaviour. Please help it is driving me crazy, I have googled and not found the answer why. I think it is in my create method within my UserSerializer class. It is also not saving the avatar if any of the other fields are changed within the profile object. Very strange. It was all working fine and for some reason now its not logging in users. Here is the model: class Profile(models.Model): user = models.OneToOneField(User, primary_key=True, on_delete=models.CASCADE) name = models.CharField(max_length=100, blank=True, null=True) occupation = models.CharField(max_length=100, blank=True, null=True) residence = models.CharField(max_length=100, blank=True, null=True) email = models.CharField(max_length=100, blank=True, null=True) active_id = models.BooleanField(default=True) avatar = models.ImageField(null=True, blank=True, upload_to ='uploads/profile_pics/',default='uploads/default.jpg') def __str__(self): return self.user.username def save(self, *args, **kwargs): super(Profile, self).save(*args, **kwargs) … -

Annotating Django records with GeoDjango Distance objects fails
I have a table with a GeoDjango GeometryField, and records include both points and polygons. I need to return those records with Point geometry within a given distance in km from a given point, for an external API.

But when I run the view, it hangs on the annotate() step, with this error: File "/MyApp/api/views.py", line 102, in get qs1 = qs0.annotate(distance=Distance('geom', pnt)) TypeError: __init__() takes from 1 to 2 positional arguments but 3 were given What I can't figure out is why I can step through all the lines to create qs2, as the qs.count() and qs2 sorted results show, but when I run that code via a URL, it breaks at annotate(). model from django.contrib.gis.db import models as geomodels class PlaceGeom(models.Model): place = models.ForeignKey(Place,related_name='geoms') geom = geomodels.GeometryField(null=True, blank=True, srid=4326) view from django.contrib.gis.geos import Polygon, Point from django.contrib.gis.measure import D, Distance class SpatialAPIView(generics.ListAPIView): def get(self, format=None, *args, **kwargs): params = self.request.query_params lon = params.get('lon', None) lat = params.get('lat', None) dist = params.get('km', None) pnt = Point(float(lon), … -
