For loop indentation is not taking place in jinja2 templating in vscode
I am writing a for loop or if else using jinja2 templating but it is not giving me indentation in vscode. Fore example, I wrote this: {% extends 'base.html' %} {% block content %} <h2>This is Item List</h2> {% for item in items %} <p>{{items}}</p> {% endfor %} {% endblock content %} But when I press Ctrl s or save it manually, it loses the indentation. The code becomes like this: {% extends 'base.html' %} {% block content %} <h2>This is Item List</h2> {% for item in items %} <p>{{items}}</p> {% endfor %} {% endblock content %} This is happening for for loops, if else and everything inside jinja2 templating. Not happening in normal python codes. This is not giving any error, but I feel distressed. How to solve it. -

whats the right way for read MySQL database with django
I'm new to django I have a local application I wrote in python that writes scientific data to a MySQL database hosted on a digital ocean droplet that also runs django. I'm experiencing an intermittent problem where occasionally (maybe 1 in 3 tries) a page request produces a 'bad gateway' error message. Refreshing the page will normally produces the correct page. A page example is http://104.131.165.99/garage/ The problem is annoying and I'm not sure what the cause is but I never understood models in django and I'm not sure how to even clearly ask my question. My local application uses pymysql to connect to the MySQL database thats part of the server where django is hosted, in otherwords a mysql database thats NOT(?) really associated with the instance of django running on the server. The code in my django app (see below) that runs when a page is requested uses pymysql with a host address of 127.0.0.1 to read and manipulate the MwSQL data. Whether or not this is the cause of my problem, I always wondered if this was the proper way to read mysql data in django considering the app writing to that database is on a different … -

django and AWS: Which is better lambda or fargate
I currently use docker-compose.yml to deploy my django application on an AWS EC2 instance. But i feel the need for scaling and load balancing. I have two choices AWS lambda (using zappa - but heard that this is no longer maintained) AWS fargate (not sure how to use the docker-compose.yml file here) My django application required some big libraries like pandas etc. Currently i use docker-compose.yml file to run the django application. My docker-compose.yml file is as below I have django app image, reactjs app image, postgres, redis and nginx. # My version of docker = 18.09.4-ce # Compose file format supported till version 18.06.0+ is 3.7 version: "3.7" services: nginx: image: nginx:1.19.0-alpine ports: - 80:80 volumes: - ./nginx/localhost/configs:/etc/nginx/configs networks: - nginx_network postgresql: image: "postgres:13-alpine" restart: always volumes: - type: bind source: ../DO_NOT_DELETE_postgres_data target: /var/lib/postgresql/data environment: POSTGRES_DB: ${POSTGRES_DB} POSTGRES_USER: ${POSTGRES_USER} POSTGRES_PASSWORD: ${POSTGRES_PASSWORD} PGDATA: "/var/lib/postgresql/data/pgdata" networks: - postgresql_network redis: image: "redis:5.0.9-alpine3.11" command: redis-server environment: - REDIS_REPLICATION_MODE=master networks: # connect to the bridge - redis_network celery_worker: image: "python3.9_django_image" command: - sh -c celery -A celery_worker.celery worker --pool=solo --loglevel=debug depends_on: - redis networks: # connect to the bridge - redis_network - postgresql_network webapp: image: "python3.9_django_image" command: - sh -c python manage.py runserver 0.0.0.0:8000 …
