Nginx, Django Static files, Docker, Oh My
First, everything works great in my development system. On my deployment server I'm running Nginx in a docker and gunicorn serving my django app in a second docker. I've configured Nginx to serve up the static files. If I don't copy the contents of my static_cdn folder (of static files) to the Nginx docker, I see this error in the console window, GET http://<my_ip>:1337/static/pb_django/home.css net::ERR_ABORTED 404 (Not Found) and my web page text is left aligned. If I do copy the static files folder into the Nginx docker, I don't get the error message and my text is centered (as instructed by my css). However, if I then change my css, it seems to have no effect on the displayed page. Thoughts or suggestions? Here's my code: Nginx Dockerfile where static_cdn contains my static files FROM nginx:alpine RUN rm -f /etc/nginx/conf.d/default.conf COPY nginx.conf /etc/nginx/conf.d/default.conf COPY static_cdn /static nginx.conf upstream pb_django { server web:8000 fail_timeout=0; } server { root /; listen 80; location / { proxy_pass http://pb_django/; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; proxy_read_timeout 10m; proxy_connect_timeout 10m; client_max_body_size 700m; } location /static/ { } } -

how to pre run rest APIs and store into Redis Cache with Django
I have a dashboard where customers can request forms which runs a REST API. But when they request the form it takes a while (around two minutes) to come back if it's the first time running the request. However, if I create a program/dashboard that pre runs these API calls which preloads the forms into our Redis Cache it would speed up the customer request to around (5 seconds) because we clear our Redis Cache once a week. -

How to get results of only the primary key and not all results in django-rest-framework?
In my django app, i need to check if a user exists using a phone number. The login is done using phone number and OTP.

Fetch and return one field from database using django_restframework
So I have been trying to make an API with Django rest_framework that will return only 1 field from a table. I have been trying to follow the example from Django Rest Framework: Dynamically return subset of fields, but have been unable to recreate it. whenever I write "http://localhost:8000/api/students/fields=id/", I get a 404 error with "details": "not found" I have also been experimenting with adding an extra method in the view class, like in this example: @action(methods=['get'], detail=False) def newest(self, request): newest = self.get_queryset().order_by('created_at').last() serializer = self.get_serializer_class()(newest) return Response(serializer.data) with something like "get_id_list" instead, but I haven't quite figured it out. Also, does anyone know if these methods will first retrieve all fields from the database, and then filter out what it needs, or will the query adjust to only ask for the specified fields? The tables can get quite large, so it might save a lot of time if it doesn't fetch unnecessary data. Here is the code in serializer.py from rest_framework.serializers import ModelSerializer from .models import Student, Coverage class DynamicFieldsModelSerializer(ModelSerializer): """ A ModelSerializer that takes an additional `fields` argument that controls which fields should be displayed. """ def __init__(self, *args, **kwargs): # Don't pass the 'fields' arg up … -

Django - Use foreign keys as choices for choice-field
Suppose I have the following models (Does not really matter, any model whatsoever will do) class Model0(models.Model): pass class Model1(models.Model): pass How can I pass them as choices to another Model, something like this: class Model3(models.Model): CHOICES = [ (models.ForeignKey(Model0,related_name='model_0',on_delete=models.CASCADE),'model0'), (models.ForeignKey(comment,related_name='model_1',on_delete=models.CASCADE),'model1'), ] choice_collumn = models.ForeignKey(choices=REPORT_TYPES) #it actually has a choices keyword argument The idea is that it will either have a Foreign key relationship to Model 0 or to Model 1. The way I am dealing with this is by setting one of them to null model_0_relationship = models.ForeignKey(Model0,null=True) model_1_relationship = models.ForeignKey(Model1,null=True) But what if I have way more than 2? is there a better solution?
