django StreamingHttpResponse picamera runs but does not render the stream, please advise
I hope I find you well. I am really struggling with a personal project and would be really grateful if someone could please set me straight. I wish to stream video from a picamera in django. I saw some cv2 implementations, had some trouble with cv2 and decided to try an alternate route. Some of the code here is lifted from the picamera documentation and some is from some of the cv2 implementations I've come across. When I hit the django url, the camera begins to stream however the webpage is grey with a small box at the centre with no visible stream. Full code posted below. This is what I see Is anyone able to point me in the right direction? Thank you, Darren from django.shortcuts import render from django.http import HttpResponse from django.http import StreamingHttpResponse from doron.models import Storage from django.views import generic import picamera import io from threading import Condition from time import sleep class StreamingOutput(object): def __init__(self): self.frame = None self.buffer = io.BytesIO() self.condition = Condition() def write(self, buf): if buf.startswith(b'\xff\xd8'): # New frame, copy the existing buffer's content and notify all # clients it's available self.buffer.truncate() with self.condition: self.frame = self.buffer.getvalue() self.condition.notify_all() self.buffer.seek(0) return self.buffer.write(buf) … -
Is there a shorter / simpler query than this one?
I have this very simple models: a Clip can have many AdBase and an AdBase can have many Clip's. class AdBase(models.Model): title = models.CharField(max_length=200, default=None, null=True, blank=False) class Clip(models.Model): ads = models.ManyToManyField(AdBase, related_name='clips', through='ClipAd') class ClipAd(models.Model): clip = models.ForeignKey(Clip, on_delete=models.CASCADE, blank=False, null=False) ad = models.ForeignKey(AdBase, on_delete=models.CASCADE, blank=False, null=False) position = models.IntegerField(default=0, blank=False, null=False) I want in the class Clip, a query which returns all its clips ordered by their position. I've come up with this: class Clip(models.Model): ads = models.ManyToManyField(AdBase, related_name='clips', through='ClipAd') def ads_by_position(self): # there might be a simpler query than this: return [a.ad for a in ClipAd.objects.filter(clip=self).order_by('position')] But I'm sure there's a simpler syntax using the ads property of my class Clip but I didn't find one. Any idea (or is this the only solution)? -

How to link to a particular post id

Need help understand the behavior of URLs for a django website
I am coding a website for practice which has the following functionality 1) Display employee data (localhost:8000/payroll) 2) Add Employee (localhost:8000/addemployee) 3) Edit Employee (localhost:8000/editemployee) 4) Download report (localhost:8000/downloadreport) Below screenshots indicate the operations as they happen. homepage delete employee Code for my deleteemployee view is as follows where if the delete succeeds I use render to take the user back to my home page(at least I think that is how it should work). But if you notice the URL never changes to index i.e localhost:8000/payroll even though the homepage is displayed the delete employee URL is still showing. What am I doing wrong here ?

How to segment WebM audio data
Consider a basic web application which livestreams audio from one client to the server and then back down to many other clients. So far so good, I setup a website that just does that using just JavaScript and Django (Python). However, there is a bug in my approach. If someone loads the website in the middle of a livestream the audio does not play. After lots of investigation, this is due to the lack of an initialization segment and not properly segmenting the audio data. A little more context here: Unable jump into stream from media recorder using media source with socket.io So before I heed the advice from StackOverflow and rip this WebM audio file apart byte by byte - has someone else done the hard work for me already? In Python, what is the easiest way for me to extract the initialization segment and each successive audio cluster from an WebM audio file? To be specific, the file is being created from the front-end using this mimeType: new MediaRecorder(mediaStream, {'mimeType': 'audio/webm; codecs="opus"',}); -

Django, and React inside Docker inside a single Digital Ocean Droplet: 400 Bad Request for Django, React works fine
I have Django and React inside the same Docker container using docker-compose.yml and running this container inside a Digital Ocean Droplet running Ubuntu. When I navigate to http://my_ip_address:3000 which is the React app, it works just fine, but when I navigate to http://my_ip_address:8000 which is the Django app, I get a 400 Bad Request error from the server. project/back-end/Dockerfile FROM python:3.7 ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 WORKDIR /nerdrich COPY Pipfile Pipfile.lock /nerdrich/ RUN pip install pipenv && pipenv install --system COPY . /nerdrich/ EXPOSE 8000 project/front-end/Dockerfile # official node.js runtime for Docker FROM node:12 # Create and set the directory for this container WORKDIR /app/ # Install Application dependencies COPY package.json yarn.lock /app/ RUN yarn install --no-optional # Copy over the rest of the project COPY . /app/ # Set the default port for the container EXPOSE 3000 CMD yarn start project/docker-compose.yml version: "3" services: web: build: ./back-end command: python /nerdrich/manage.py runserver volumes: - ./back-end:/nerdrich ports: - "8000:8000" stdin_open: true tty: true client: build: ./front-end volumes: - ./front-end:/app - /app/node_modules ports: - '3000:3000' stdin_open: true environment: - NODE_ENV=development depends_on: - "web" command: yarn start project/back-end/nerdrich/.env ALLOWED_HOSTS=['165.227.82.162'] I can provide any additional information if needed.
