Can't get docker to run a development container for a Django app: python: can't open file '/app/manage.py': [Errno 2] No such file or directory
I managed to get my production version of the app running using an entrypoint and a deploy version of the docker-compose file, however I still need to fix some bugs in the app and for that I wanted to run my application with a mounted volume and a "python manage.py runserver" command so that I can see the changes that I make in the code in real-time, but when I try to do that i get the following error: backend-dev | python: can't open file '/app/manage.py': [Errno 2] No such file or directory backend-dev exited with code 2 I couldn't see the filesystem of the container using the "docker exec" command because it only works on running containers, but I managed to overcome that issue by running those commands: > docker commit 3c3a8e5970e9 backend-dev-debug > docker run -it --rm --entrypoint sh backend-dev-debug and from there I could see that the manage.py file is actually present there. I also searched the internet and I saw that other people have also been coming across this problem, for example here: When run docker-compose up I get python: can't open file 'manage.py': [Errno 2] No such file or directory One user in this thread … -
DataTables - Export data with Ajax without downloading file
I am using the DataTables JS library with Excel/CSV buttons, and it's working great. My next challenge is uploading that Excel/CSV file to another destination/server, without downloading the file locally to the machine. In other words, on button click, I need to send the file to the backend with Ajax so it can then be uploaded as a file to another server. Any ideas? -

What is the correct way to implement authentication via email accounts (using given email addresses)?
I am currently developing a website for my school and am trying to implement authentication using email accounts. I have a database of emails that can log into the website. So, there will be no sign-ups (only sign-ins). The question arises, because I do not want to use a separate password for the website (a multitude of reasons, listed below). Thus, the intended flow would include users signing-in with email accounts. Although I am seeking a general answer, here are some specifics: The email service provider (ESP) is Google, but the domain (@something.com) is different. I am using Django+postgres There are roughly 100 emails, so the project isn't big As a further note, since the ESP is Google, I will be using Google Identity Services (GIS) APIs. Of course, the most straightforward way of implementing this would be just to let the users sign-in using the GIS, and then retrieve the email address used to check whether it is in the database. This very well might be the best way of doing this, but it seems a tiny bit clunky - since I already know the email addresses that the users will use. The preferred flow would be to check … -

Logic inside Django serializer
I have a Django serializer implementation that has a field which contains a list as part of a JWT authentication process. For example: class MySerializer(serializers.ModelSerializer): class Meta: field = ['a', 'b', 'c'] I then have some logic in my user model class MyUser(PermissionMixin, AbstractBaseUser): permissions = ['OK', 'NOT_OK'] I can access my users from the following logic inside my serializer self.context['request'].user.permissions I would now like to only share parts a and b of field if the user is not permitted to access c. In other words I want to do something roughly equivalent to class MySerializer(serializers.ModelSerializer): class Meta: if 'OK' in self.context['request'].user.permissions: field = ['a', 'b', 'c'] else: field = ['a', 'b'] However, the Meta class does not have self attached. What is the best design pattern to achieve what I want? Is the serializer the best place to house this logic? -
Django REST Framework Interface JWT Auth
I am trying to integrate the django-rest-framework-simplejwt package for jwt auth. Everything works as expected, the only issues is that I don't know how to make it work with the Django Rest Framework Interface. When I try to access a "protected" view I get the expected Not Authorized response, but there is no way for me to add the token when making the request. And when I try to Login I get redirected to the django login, which doesn't help. How can I add the Bearer token to the Django Rest Framework Interface? To circumvent this, I've installed the drf_spectacular package that does its job very well, I am just curios if I can make the Django Rest Framework Interface work with the jwt token so that I don't need the drf_spectacular package. Some of my configs: INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "corsheaders", "rest_framework", "rest_framework_simplejwt", "drf_spectacular", "todo_api", ] REST_FRAMEWORK = { "DEFAULT_PERMISSION_CLASSES": ("rest_framework.permissions.IsAuthenticated",), "DEFAULT_SCHEMA_CLASS": "drf_spectacular.openapi.AutoSchema", "DEFAULT_AUTHENTICATION_CLASSES": ( "rest_framework_simplejwt.authentication.JWTAuthentication", ), } MIDDLEWARE = [ "django.middleware.security.SecurityMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "corsheaders.middleware.CorsMiddleware", "django.middleware.common.CommonMiddleware", "django.middleware.csrf.CsrfViewMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.contrib.messages.middleware.MessageMiddleware", "django.middleware.clickjacking.XFrameOptionsMiddleware", ] #TODOListApiView.py from .serializers import TodoSerializer from drf_spectacular.utils import extend_schema from rest_framework_simplejwt.authentication import JWTAuthentication class TodoListApiView(APIView): # add permission to check if user is authenticated … -

Redirect to an external URL in Django does not work
I have been trying to redirect to an external URL in Django view but somehow it does not seem to work. The image below is what I get. Apparently it is able to print out the 2 "print" statements, showing that there is no error with the line of code: link=redirect("https://google.com"). However, it just does not return me the redirect page. Is there something that I am supposed to write at urls.py? In the urls.py file: When the 3rd line of code representing the redirect url path is written, I get the error "Forbidden (CSRF token missing.): /deliveryJob". Without this line of code, no redirects or errors happen.

Django Nested Serializers won't work independently- Key Error /dashboard/api/institution/editor/ 'id'
I'm trying to create an app using JQuery Datatables Editor and a Django REST framework API. Whenever I try to create an entry, I am returned the above key error.

How to configure nginx to serve Django at a different endpoint?
I separated my frontend (NextJS) and my backend (Django). I want to serve my Django app at /api using Nginx. events {} http { server { listen 80; gzip on; server_name $HOST; location /api/ { proxy_pass http://backend:8000/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } location / { proxy_pass http://frontend:3000/; } } } where backend and frontend are corresponding docker-compose services. Django is not recognizing my configuration and is having a lot of issues. For example when I access /api/admin it redirects to /admin and causes troubles. I searched around but can't find any answers. How can I solve this? -
Making a file available at url using uWSGI, Django and nginx
I'm attempting to have Django/nginx serve a specific file under a specific URL, unrelated to the Django app itself. I have a .php file I'd like to serve and be displayed as a normal PHP. The PHP file I'm using: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>PHP - Hello, World!</title> </head> <body> <h1><?php echo 'Hello, World!'; ?></h1> </body> </html> I tried adding this to my nginx configuration to achieve it: location /deploy { alias /var/www/deploy.php } When I then attempted to run my uWSGI app, going to that URL (example.com/deploy) does indeed redirect to deploy.php, but I get a pop-up to save the file on my PC (download) instead of it being displayed as a webpage. I'm not sure how to configure it to behave correctly, I'm working with nginx for the first time. -
Django GeometryDistance usage with postgis database
I am having some issues using GeometryDistance where I have a node point object and am trying to find the closest node in another table in the database. GeometryDistance(start_node.geom, vertex.objects.all()) This is the truncated output. GeometryDistance(Value(<Point object at 0x7f3afe8e4d90>) <-> <QuerySet [<WaysVerticesPgr: WaysVerticesPgr object (1)>, <WaysVerticesPgr: WaysVerticesPgr object (2)>, <WaysVerticesPgr: WaysVerticesPgr object (3)>, and the only reference info I can find is this from Django. I know the issue is with the WaysVerticesPgr queryset in the second position but don't know how to only get the geometry from the table. I would like to return the closest nodes in the vertex table to the start_node. the vertex table has the geometry in column 'the_geom'. vertex.objects.order_by(GeometryDistance(start_node.geom, vertex.objects.all().the_geom)) Here, the queryset doesn't have the_geom attribute. I remember reading that django doesn't evaluate querysets until it has to either through iteration or other methods but I don't know exactly how I should go about this query. Any help is appreciated.
