How to send message through django-channels from asyncio loop with add_reader
I am trying to listen for notifications from postgres database and send message through django-channels on each row insertion, for that I want to use asyncio loop, where I am adding reader for connection. However, I am receiving following error on attempt to use async_to_sync: RuntimeError: You cannot use AsyncToSync in the same thread as an async event loop - just await the async function directly. Here is my code: import asyncio import logging import channels.layers from asgiref.sync import async_to_sync from django.conf import settings from django.core.management.base import BaseCommand from django.db import connections channel_layer = channels.layers.get_channel_layer() logger = logging.getLogger(__name__) class Command(BaseCommand): def handle(self, *args, **options): conns = [(connections[db].cursor().connection, db) for db in settings.DATABASES] loop = asyncio.get_event_loop() for conn, db in conns: conn.set_isolation_level(psycopg2.extensions.ISOLATION_LEVEL_AUTOCOMMIT) cursor = conn.cursor() cursor.execute("LISTEN event_changed;") loop.add_reader(conn, partial(self.handle_notify, conn=conn, db=db)) logger.info("Starting runlistener loop.") loop.run_forever() def handle_notify(self, conn, db): conn.poll() for notify in conn.notifies: logger.debug(f"new event received on db {db}: {notify.payload}.") async_to_sync(channel_layer.group_send)( db, {"type": "on_new_event", "event": notify.payload} ) conn.notifies.clear() I can't use await in handle_notify since it is not async function and I couldn't find any way to use async function as a callback for add_reader. I've managed to implement this functionality without asyncio, by simply checking connection with select.select in … -

How to make table editable in django on the clientside
I am building this Django webapp, where I have data stored in the SQLite. And being fetched into a table in the client side. But I have this idea of patching the data from the table itself, just like Edit in grid view, of sharepoint list. Where If I click the toggle button 'editable mode', the all cells become editable and after making necessary changes, if click the toggle button again, the changes should be saved in the database as well. Below are the snippets of the project. views.py class EmployeeUpdateView(View): def patch(self, request, employee_id): data = json.loads(request.body) try: employee = Employee.objects.get(id=employee_id) for change in data: field_name = change['field_name'] field_value = change['field_value'] setattr(employee, field_name, field_value) employee.save() return JsonResponse({'success': True}) except Employee.DoesNotExist: return JsonResponse({'success': False, 'error': 'Employee not found'}) except Exception: return JsonResponse({'success': False, 'error': 'Error saving changes'}) this is url path path('update/<int:employee_id>/', EmployeeUpdateView.as_view(), name='update_employee'), this is the table template <tbody class="thead-light"> {% for employee in page_obj %} <tr style="font-size: 12px;"> <td {% if not employee.editable %}contenteditable="false"{% endif %}>{{ employee.name }}</td> <td {% if not employee.editable %}contenteditable="false"{% endif %}>{{ employee.phone }}</td> <td {% if not employee.editable %}contenteditable="false"{% endif %}>{{ employee.dob }}</td> <td {% if not employee.editable %}contenteditable="false"{% endif %}>{{ employee.doj }}</td> … -

Convert PDF to PDF/A with python
I am working on a Python project and I need to convert a PDF file to PDF/A format programmatically. Ideally, I'm looking for a Python library or tool that supports PDF to PDF/A conversion and provides options to specify PDF/A compliance levels, such as PDF/A-1a or PDF/A-3b. Any example code or a step-by-step guide would be greatly appreciated. I have explored some libraries such as PyPDF2 and pikepdf, but I haven't found a straightforward way to achieve this. Can anyone provide guidance on how to convert a PDF file to PDF/A using Python? -
Django: Rest Framework (Serializer)
I'm new to using the django rest framework. I'm trying to understand how I can validate a field with the serializer based on the input from the user, for example: Serializer: from rest_framework import serializers VALID_REGION = 'region' def validate_region(value): if value != VALID_REGION: raise serializers.ValidationError('Invalid region, make sure region parameter is spelled correctly.') return value class RegionSerializer(serializers.Serializer): region = serializers.CharField(required=False, validators=[validate_region]) Here I want to validate that the region is spelled correctly. views.py def get(request, *args, **kwargs): serializer = RegionSerializer(data = request.data) if serializer.is_valid(): data = serializer.validated_data region = data.get('region', '') regions = region_lib.get_regions(region) return Response({"regions" : regions}, status=status.HTTP_200_OK) else: errors = serializer.errors return Response({"error" : errors}, status=status.HTTP_400_BAD_REQUEST) Here I pass 'regoin' misspelling it intentionally. { "regoin": "Test" } When I run serializer.is_valid() it returns true. Not sure what I'm missing. -
In Django, how to get the return of two functions in the same html page? Error: TypeError: kwargs argument must be a dict, but got function
In Django I have two functions contained in views.py. One is called def city_detail and the other is called def DemoView. Both return return render(request, 'app1/home.html', context). In url.py I would like to use both functions, but it seems I can only use 1 at a time. If I use only one of the two, then it works (only one of the two works). If I write in urlpatterns I write: path('home/', views.city_detail, views.DemoView, name='home'), path('home/', views.DemoView, name='home'), I get the error: raiseTypeError( TypeError: kwargs argument must be a dict, but got function.

Unable to fetch data with axios from Django backend using relative path
I am currently developing a web application using React for my frontend and Django for my backend. The frontend and backend are running on separate local servers. I am trying to fetch some data from my Django backend using axios in my React application with the following code: const handleButtonClick = () => { setLoading(true); axios .get("/bucket-size/") .then((response) => { const size = response.data.bucketsize; const unit = response.data.unit; setOutput(size + " " + unit); }) .catch((error) => { console.error(error); }) .finally(() => { setLoading(false); }); }; The Django backend route looks like this: path('bucket-size/', BucketSize.as_view(), name='bucket-size'), Note -- i do not want to add a proxy to my package.json since the backend will be running on Docker and i want it to fetch relatively. Can anyone help? -

TinyMCE is not working correctly in my django project
I have created a Django blog site where I can write blog posts both from the main site and the admin site. To compose my blog posts, I am using the TinyMCE editor. When I am in the admin site, I can successfully write and submit my blog posts using TinyMCE. However, when I attempt to write a blog post from the main site using TinyMCE, I encounter an issue. Although my submit button appears to be working correctly, it does not perform any action upon clicking it. Strangely, if I refresh the page and then click the submit button again, my blog post gets posted, and everything works fine from that point onward. Please tell me What is the mistake that I'm doing. This is my tiny.js file var script= document.createElement('script'); script.type='text/javascript'; script.src="https://cdn.tiny.cloud/1/no-api-key/tinymce/5/tinymce.min.js"; document.head.appendChild(script); script.onload=function(){ tinymce.init({ selector: "#id_content", height:656, plugins: [ 'advlist autolink link image lists charmap print preview hr anchor pagebreak', 'searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking', 'table emoticons template paste help' ], toolbar: 'undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | ' + 'bullist numlist outdent indent | link image | print preview media fullpage | ' + 'forecolor … -
Gunicorn Fargate ELB healthcecks fail before auto scale
I have setup a django application using gunicorn server on ECS with Fargate backend. I have setup auto scaling based on both CPU and Memory utilisation. Fargate capacity: 2 vCPU and 4 GB RAM The problem is that whenever the load is high, even before the CPU utilisation is high, the ELB healthchecks are failing and as a result the task is getting deregistered and never leads to auto scaling. gunicorn is running with 2 workers and 4 threads. gunicorn <appname>.wsgi:application --workers 2 --threads 4 I'm trying to understand the reason for this and how to solve this issue. -

Is it possible in Django to use threaded=True (like in Flask) to e to handle each request in a new thread?
On Flask you can use threaded=True to handle each request in a new thread. For example: if __name__=="__main__": app.run(host="0.0.0.0", port=8000, threaded=True) With Django can i use something like threaded=True (or simil) to handle each request in a new thread? (without using async). Or is it more complicated in Django? -
