DEBUG 2020-09-06 07:39:38,589 retryhandler 6 139721333720896 No retry needed. These are easy to recognize, because they start with the log level DEBUG. As soon as a the uWSGI process starts, I stop seeing any log events from Django. The only thing I see are uWSGI log events like: [pid: 13|app: 0|req: 2/1] 10.0.2.249 () {30 vars in 352 bytes} [Sun Sep 6 07:39:46 2020] GET / => generated 3877 bytes in 444 msecs (HTTP/1.1 200) 4 headers in 128 bytes (1 switches on core 1) In the Dockerfile I am setting 3 additional uWSGI related environment variables: ENV UWSGI_WSGI_FILE=sanctionsio/wsgi.py ENV UWSGI_HTTP=:8000 UWSGI_MASTER=1 UWSGI_HTTP_AUTO_CHUNKED=1 UWSGI_HTTP_KEEPALIVE=1 UWSGI_LAZY_APPS=1 UWSGI_WSGI_ENV_BEHAVIOR=holy ENV UWSGI_WORKERS=2 UWSGI_THREADS=4 Django logging is set up like this: LOGGING_LEVEL = 'DEBUG' LOGGING = { 'version': 1, … -

Push Notifications with Angular and Django Rest Framework
I want to build a Progressive Web App with Angular in the Frontend and Django/Django Rest Framework in the backend (PostgreSQL as an RDBMS). I want to have Push Notifications in my system, for example, I have a table of 'payments' in my DB, and one day before the 'due_date' of a 'payment' I want to send a push notification to the User. Can you recommend me some libraries, third-party Message Brokers maybe that would go well with Angular and DRF. I am not very familiar with Angular, but I will mostly handle the backend stuff. -

Version django : 3.1 djangorestframework:3.11.1 python : 3.7.6 Situation I am trying to creating an app that each user can exchange their items. I use Django in server side, and React in client side. In order to introduce authentication and registration, I created User model in models.py. However, when I try to introducing these features in Django Rest Framework I notice that I may not be able to do that using User I define, perhaps I have to use admin-user django provides. Question __ First of all, can I introduce authentication and registration features using User model I define myself ?__ I found I can edit admin-user itself so I edited it. It doesn't work. Honestly, I don't understand whether I can introduce these features using User model as well. I would like to teach me how to figure it out. And I would like to those who have combined Django and React to teach me some way to realize authentication and registration. Thank you very much. This is my User model. … -

Order of Values from a Django Foreign Key Reverse Lookup
I have two models, Document and DocumentImage. Document has a primary key called document_id, and a foreign key to DocumentImage. Say I have a list of document_ids and I run this query: images = DocumentImage.objects.filter(document__in=document_ids) as a reverse lookup through the foreign key relationship Is it true that images[0] is derived from document_ids[0], and images[1] is derived from document_ids[1], etc? I need to combine each element in images with each element in document_ids, and I want to make sure that I have the correct document_id for that element from images. In other words, I want to do this: for document_id, image in zip(document_ids, images): # associate the document_id with the image and make sure that each image is associated with the correct document_id.
