Can you add a Browsable API into an ASP.NET application?
The Django web framework has a Browsable API and I would like to implement something similar in my ASP.NET (with ReactJS) application. Essentially, suppose that there's an API endpoint called api/test; I would like to be able to navigate to https://.../api/test in a web browser and be presented with a web page (React component) that contains what api/test normally returns but in a better, human-readable format like Django does. But when accessed as an API, it returns the content without the surrounding HTML page. The simple controller would look like: [ApiController] [Route("api/[controller]")] public class TestController : ControllerBase { [HttpGet] [Produces("text/json")] public IList<string> Get() { return new string[] { "hello", "world" }; } } It seems that something similar to Content Negotiation would work. So, I would either have to implement a custom formatter (which I'm not sure is the right approach) or make a middleware of my own. Does this sort of thing already exist somehow? Any suggestions on how to implement it if it doesn't already exist? Thanks in advance! -

Adding Websockets to Django server deployed on Azure Appservice
I have a Django application which starts a server using the websockets https://websockets.readthedocs.io/en/stable/index.html library for Python. The manage.py file looks like this: import os import sys import asyncio import threading if __name__ == '__main__': os.environ.setdefault( 'DJANGO_SETTINGS_MODULE', 'UPH_Chart_Re.settings') try: from django.core.management import execute_from_command_line except ImportError as exc: raise ImportError( "Couldn't import Django.

I have tried setting the port to 443, which is considered a forbidden port since … -

Nextcloud as User Master for other web apps (i.e. django based)
I have a Nextcloud instance where all potential users have an account. I would like to set up an Open Source Doodle (Bitpoll) that is django based, as I don't like the nextcloud poll app. For security reasons I would like to limit the Doodle app to users of my nextcloud. Also I don't want them to enter a password using the doodle app (so single sign on is required). I imagine a similar user user flow as the Login in with Github button that can be used to also create user accounts. The doodle app supports LDAP, so does nextcloud. There are django modules for OAuth as well as for the nextcloud. I have no LDAP experience at all and only very little OAuth experience. With which Nextcloud Settings / Apps and which Django Apps (and an idea of the settings) can I realize the explained scenario? To be more precise: Do I need to use LDAP at all? Or can I configure OAuth in a way that all users that come from nextcloud.mydomain.org generate a new account in the app? What are the correct OAuth terms for my nextcloud istance and for the doodle app in this scenario? … -
Images not showing after about 1 day of upload with editors (ckeditor)

How to serialize ChoiceFields in Django Rest Framework?
First time Python user here, coming from Javascript world. I'm able to retrieve my Model serialized to JSON from Django API and display it on the frontend written in React. But now I just added one more field priority to the Model that has multiple choices and I struggle to get these choices to the frontend (I want to display them in a dropdown and update REST API). Migration was successful and I can select choices from the back end but on the frontend I just get the default value set from migrations. Here is my code right now: models.py class Todo(models.Model): title = models.CharField(max_length=120) description = models.TextField() completed = models.BooleanField(default=False) priority_choices = [ ('High', 'High'), ('Medium', 'Medium'), ('Low', 'Low'), ] priority= models.CharField(max_length=6, choices=priority_choices, default='Low') #new field def __str__(self): return self.title serializers.py from rest_framework import serializers from .models import Todo class TodoSerializer(serializers.ModelSerializer): class Meta: model = Todo fields = ('id', 'title', 'description', 'completed', 'priority') views.py class TodoView(viewsets.ModelViewSet): serializer_class = TodoSerializer queryset = Todo.objects.all() I just want the simplest solution, preferably to just update TodoSerializer(serializers.ModelSerializer) class inside serializers.py so that it would all come from this one Model.

Django: What's the difference between Queryset.union() and the OR operator?
When combining QuerySets, what's the difference between the QuerySet.union() method and using the OR operator between QuerySets |? Consider the following 2 QuerySets: qs1 = Candidate.objects.filter(id=1) qs2 = Candidate.objects.filter(id=2) How is qs1 | qs2 different from qs1.union(qs2)? Is there some subtlety under the hood that I'm missing? -
Evaluating Django QuerySet is fast, but still consumes a lot of server time
Using Django Query Profiler, I get the following results when loading my page. My query only takes 48ms to run, but the total server time is nearly 2 seconds! I have been able to verify that the query is fast by printing out the raw query and then running it manually. The relevant code in my ListAPIView view looks like: def get_queryset(self): start = time.perf_counter() queryset = MyModel.objects.all() \ .prefetch_related( # Prefetch related fields ).defer( # Don't select these fields ) print(len(queryset)) end = time.perf_counter() print(f"Evaluation time: {(end - start):.2f}s") return [ # Return hardcoded JSON result with single value to eliminate other factors ] The print(len(queryset)) statement is where the evaluation occurs. For some reason, this takes almost 2 seconds to complete, but only 48 ms of it is spent on the database. For some perspective, there are only 11 rows in MyModel. I wanted to rule out the possibilities that the server time was due to transforming the data, serializing the data, etc., so I am just returning a single JSON object. Given that all the other views in my application work just fine, I see no reason the server time can't be at least 10x faster. Any … -
