communication between javascript and python (django)
i try to exchange data between javascript and python. I am currently using AJAX. (is there anything better?) I think one of the problems is that the data exchange happens after a user logs in, so that django adjusts the paths. in the .js the Ajax command is as follows: $.ajax({ url:'bla', type: "POST", data: {stock : 42}, success:function(response){}, complete:function(){}, error:function (xhr, textStatus, thrownError){} }); and in urls.py it says: path(r'bla/', views.YourViewsHere, name='bla'), when I do that the server tells me a 404 error that it cannot find the page because the username is in the path. Therefore I have expanded the Ajax url with the app names: $.ajax({ url:'blub:bla', type: "POST", data: {stock : 42}, success:function(response){}, complete:function(){}, error:function (xhr, textStatus, thrownError){} }); now i don't even get an error message. the views look like: def YourViewsHere(request): print("bla") if request.method == 'GET': print("blub") elif request.method == 'POST': print(request.POST.get('data')) what am I missing? -

How to center a Leaflet Map forms in a Django template

running a service in django and doing some things when a specific event happens
Using Django I want to receive some input from the user and then read a webpage and look for some specific data like a number and do this for unlimited times(reading the webpage not receiving input) and when there is a change in this number, based on the user's input I want to insert a record into a table. It's like a service that the user enables it giving some inputs, and the service gets running for unlimited times and it doesn't stop unless user stops it. Like in the first run there is a number on the webpage which is for example 2 and next time the service reads the webpage it's increased to 3 then it inserts value 3 into a local database and runs again and again.

Celery not running at times in docker
I have been going bonkers over this one, the celery service in my docker-compose.yml just does not pick up tasks (sometimes). It works at times though Dockerfile: FROM python:3.6 RUN apt-get update RUN mkdir /web_back WORKDIR /web_back COPY web/requirements.txt ./ RUN pip install --no-cache-dir -r requirements.txt COPY web/ . docker-compose.yml (Taken out a few services for the sake of understanding) version: '3' services: web_serv: restart: always build: . container_name: web_back_01 env_file: - ./envs/web_back_01.env volumes: - ./web/:/web_back depends_on: - web_postgres expose: - 8282 extra_hosts: - "dockerhost:104.10.4.11" command: bash -c "./initiate.sh" web_postgres: restart: always build: ./postgres container_name: web_postgres_01 # restart: unless-stopped ports: - "5433:5432" environment: # will be used by the init script LC_ALL: C.UTF-8 POSTGRES_USER: web POSTGRES_PASSWORD: web POSTGRES_DB: web volumes: - pgdata:/var/lib/postgresql/data/ nginx: restart: always build: ./nginx/ container_name: web_nginx_01 volumes: - ./nginx/:/etc/nginx/conf.d - ./logs/:/code/logs - ./web/static/:/static_cdn/ - ./web/media/:/media_cdn/ ports: - "80:80" links: - web_serv redis: restart: always container_name: web_redis_01 ports: - "6379:6379" links: - web_serv image: redis celery: build: . volumes: - ./web/:/web_back container_name: web_celery_01 command: celery -A web worker -l info links: - redis depends_on: - redis volumes: pgdata: media: static: settings.py CELERY_BROKER_URL = 'redis://redis:6379' CELERY_RESULT_BACKEND = 'redis://redis:6379' CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_RESULT_SERIALIZER = 'json' CELERY_TASK_SERIALIZER = 'json' Any help …
