Django app deployment through ECS with uWSGI and nginx can't find some files
I'm currently deploying a containerized Django application on Amazon ECS using uWSGI and nginx, but I'm having some issues with my proxy finding some of the static content. When I test a local proxy deployment using docker-compose it works fine, but not when it's deployed through ECS. Here's my settings.py: # Static files (CSS, JavaScript, Images) STATIC_URL = '/static/static/' MEDIA_URL = '/static/media/' STATIC_ROOT = '/vol/web/static' MEDIA_ROOT = '/vol/web/media' STATICFILES_DIRS = [ # '/var/www/static/', os.path.join(BASE_DIR, 'core/static'), ] Here's my proxy config: server { listen ${LISTEN_PORT}; location /static { alias /vol/static; } location / { uwsgi_pass ${APP_HOST}:${APP_PORT}; include /etc/nginx/uwsgi_params; client_max_body_size 10M; } } Container definition for ECS: [ { "name": "app", "image": "${app_image}", "essential": true, "memoryReservation": 256, "environment": [ {"name": "DJANGO_SECRET_KEY", "value": "${django_secret_key}"}, {"name": "DB_HOST", "value": "${db_host}"}, {"name": "DB_NAME", "value": "${db_name}"}, {"name": "DB_USER", "value": "${db_user}"}, {"name": "DB_PASS", "value": "${db_pass}"}, {"name": "ALLOWED_HOSTS", "value": "${allowed_hosts}"} ], "logConfiguration": { "logDriver": "awslogs", "options": { "awslogs-group": "${log_group_name}", "awslogs-region": "${log_group_region}", "awslogs-stream-prefix": "app" } }, "portMappings": [ { "containerPort": 9000, "hostPort": 9000 } ], "mountPoints": [ { "readOnly": false, "containerPath": "/vol/web", "sourceVolume": "static" } ] }, { "name": "proxy", "image": "${proxy_image}", "essential": true, "portMappings": [ { "containerPort": 8000, "hostPort": 8000 } ], "memoryReservation": 256, "environment": [ {"name": "APP_HOST", "value": … -

Frontend Technology-> Angular and Backend technology-> Django = SaaS product
I am trying to deploy a SaaS product with the subject line mentioned tech stack. The problem I am facing is how we can dynamically map the frontend to the corresponding backend provided that these tech stacks are deployed in one server per each customer. I will be using AWS EC2 capabilities to launch the product but instead of manually mapping the frontend to the backend , I wanted to know if anyone can guide me on how to dynamically launch the frontend and backend mapped correctly to each other per user. Thanks, Winston John -
Django queryset latest object's attributes after group by
This is my model class MyLog(models.Model): email = models.EmailField() date = models.DateTimeField(auto_now_add=True) comment = models.CharField(max_length=150) What i am trying to do is group by email, then filter the query by repetitions greater than 5 after that get the comment field's value of the latest object (from latest date value). I am not able to acheive the last part. Here my query so far MyLog.objects.values("email").annotate(Count("id")).filter(id__count__gte=5) This much is correct I am getting output like <QuerySet [{'email': 'test@test.com', 'id__count': 6,}]> How can I query the latest comment ? I am not able to figure out how to query that. -

I've imported some mysql data into the Django mysql db. How do I get Django models to work with my existing data?
I have an existing process building data daily. I've copied tables from my main mysql to a test-mysql so I can work with the data and get it right. I found an excellent post about building the correct model python manage.py inspectdb {tablename} which was 99% correct. I have a table called main which I'd like to connect to the main model. I've 50+ tables with titles like 1234 linked by a foreign key column called G to G in main. I've just realised the way Django stores models is completely different. It stores data in tables by {appname}_{model} Have I gone about this backwards? Should I have created the Django database first, and then added to it by its conventions? I've already put a lot of work into this and it would be a lot to redo it. If its best, that's what I'll do. Thanks, T -

Django: Ajax data changes when Django gets it
Something weird is happening to me and I don't know why: I have this data that I want to send throught ajax to django: const params = { "status__in":['pendant','confirmed'], "access_date__year":2020, "access_date__month":05, "billable":true } I use datatable to creat a table with the data that I receive, this is the ajax options for datatable: const ajax_options = { ajax: { url:get_consumptions_url, data: params } } Then I get the ajax params with this code: ajax_data = request.GET.dict() SO before trying to add an array to my params everything worked fine but when I check the ajax params debugging in python I get this: { 'access_date__month': '10', 'access_date__year': '2020', 'billable': 'true', 'status__in[]': 'confirmed' } Check "status__in" it completly changed from that I had in my params. Why is this happening? -
Occasional Client 400 Errors or Prematurely Closed Connections
I have been dealing with an issue that is rare and I can't repeat it. I have 100s of users everyday uploading files to my server. 99% of the time users are fine and have no issues uploading. Occasionally though someone will have trouble uploading and the issues seems to be client side. It can be resolved by having them go to another computer to upload. Having them clear their cache and cookies I assume would work to, but it is difficult to explain to a non technical user how to do that. I use django and manifset static files so they get cache busted anytime new scripts are added. Old scripts shouldn't be being used in their browser. I have implemented multiple methods of upload for when this happens. The standard way is an ajax single request to get a progress bar. If things fail I revert them to the most basic form request no progress bar. If that fails I also have a chunked upload method that allows them to upload in chunks. The most recent time this happened it failed on all those methods. The user received a 400 error when uploading via chunked. It seemed looking … -

How can I install Django in my Docker file?

Validating keycloak bearer token on behalf of client
I want to validate bearer tokens in an API, which are passed from a browser application. The API will validate the tokens against Keycloak by calling the ../userinfo endpoint and respond with the desired content if the check runs ok. Problem is that If I pass a bearer token from the browser, or any other app for that matter (e.g. postman), to the api and try to validate it - I get "401 Token verification failed". The following works: Fetch token from Keycloak through Postman by using username and password. Fetch userinfo from Keycloak through Postman using the resulting bearer token. OR Fetch token from Keycloak directly from the API by using username and password. Fetch userinfo from Keycloak from the API using the resulting bearer token. The following does NOT work: Fetch token from Keycloak through Postman by using username and password. Send request to API, running in a docker container, containing the bearer token. API tries to fetch userinfo using the token = "401 Token verification failed" Using same client_id and client_secret in all scenarios. Is this a docker networking thing? Or is some Keycloak configuration necessary in order for the API to validate token "on behalf" of … -

Django in-memory database
I am running a web application with a low latency requirement using Django. However, my MySQL server is currently being a bottleneck. I want to replace it with a completely in-memory database.

I am running multiple Django processes and need the database to be shared among them. Are there any such databases that can be integrated with Django? -
