Protection of Django Rest Framework API with AllowAny permission
I have a full-stack app and I am taking measures to protect the application from DDOS or bot attacks. All the sensitive data is protected by IsAuthenticated permission but there are still open APIs with public data with AllowAny permissions. I have so far added throttling and limited the request rate to 100 for both anonymous and authenticated users and on the frontend side I've added Captcha to protect the server from mass user registration, what are more ways to protect the server? REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": ("accounts.authentication.Authentication",), # "EXCEPTION_HANDLER": "accounts.custom_exception_handler.custom_exception_handler" 'DEFAULT_THROTTLE_CLASSES': [ 'rest_framework.throttling.AnonRateThrottle', 'rest_framework.throttling.UserRateThrottle' ], 'DEFAULT_THROTTLE_RATES': { 'anon': '100/minute', 'user': '100/minute' } } -

Django 4.2 and NGINX - The page isn’t redirecting properly
I am trying to add ssl to my test django server that is on AWS. I followed a tutorial to add ssl with certbot, add the proxy_pass but I never got it to work, so after three days trying all kinds of things, I give up. Could you guys please have a look and let me know where I am wrong? I am also confused about the environment variables, $host is blank and so are the others, I am going to assume they should be populated? I know nothing about NGINX, sorry about the noob questions. server { listen 80 default_server; listen [::]:80 default_server; server_name _; return 404; } server { listen 80; listen [::]:80; server_name techexam.hopto.org; return 301 https://$server_name$request_uri; } server { listen 443 ssl; listen [::]:443 ssl; server_name techexam.hopto.org; ssl_certificate /etc/letsencrypt/live/techexam.hopto.org/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/techexam.hopto.org/privkey.pem; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; include /etc/nginx/mime.types; charset UTF-8; location /static/ { alias /home/sfarmer/code/django_workspace/exam/Quiz/static/Quiz/; } location /media/ { alias /home/sfarmer/code/django_workspace/exam/Quiz/static/Quiz/; } location / { proxy_pass http://127.0.0.1:8000/; proxy_set_header Host $host; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # Additional logging access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; error_page 502 /error_pages/502.html; location = /error_pages/502.html { internal; root /usr/share/nginx/html; } } } -
Gunicorn, serve VPS, can't load CSS to admin panel
Previously, I have never been involved in setting up and maintaining a VPS. I recently launched a project using ubuntu + nginx + gunicorn. Everything works fine, but the CSS are not loaded to admin panel. At first, not understanding what was the reason, I tried to install grappelli - without success. After I found information that gunicorn cannot load admin CSS. The solution I see is to configure nginx to render CSS to admin panel. However, I couldn't to set up nginx correctly when I tried to set up a server without gunicorn. As a result, the server gave the nginx stub and I couldn't log into the server (although nginx did not show any syntax errors) - I had to delete the server and set up a new one. Therefore, I ask for help: what needs to be written in the nginx configuration so that, in addition to transmitting traffic, it also gives the CSS of the admin panel? I will be grateful for any answer! -

Django: How to make model for list of string as one-to-many relation?
I have data like so: [ { "name": "Alice", "hobbies": ["programming", "swimming"] }, { "name": "Bob", "hobbies": ["sleeping", "skiing", "skating"] } ] I want to be able to use hobbies for later filtering, so I would like to have separate Hobby model with many-to-one relation to the Person model. What is a good practice to do so? Is there any simple way how to save person and hobbies at once (for example using singular serializer) and/or use serializer to retrieve data in the simmilar fashion as the input? -
Switched from WSGI to ASGI for Django Channels and now CircleCI throws "corrupted double-linked list" even though tests pass
I've been working on a project which requires WebSockets. The platform is built with Django and was running the WSGI server gunicorn. We decided to implement WebSockets using Django Channels. I set everything up including switching from gunicorn to the ASGI server daphne. Everything works great in local development environment. Deployment to AWS is working and everything works great on dev/staging. pytest works and all tests pass locally. On CircleCI all the tests are passing, but at the end of the "test" step we get the following and CircleCI shows a failed status: ================== 955 passed, 2 skipped in 216.09s (0:03:36) ================== corrupted double-linked list /bin/bash: line 2: 278 Aborted (core dumped) poetry run coverage run -m pytest $TESTFILES -vv --junitxml htmlcov/junit.xml Exited with code exit status 134 CircleCI received exit code 134 There are no other errors, warnings, or unexpected output. I cannot replicate the issue outside of CircleCI. I tried adding the @pytest.mark.asyncio decorator to the one async test we have and still got the above. Even when I totally remove said test CircleCI still throws the same. Google has not been helpful. Edit: This same thing has also happened a couple of times during the "migrate" step … -
Python Django: Inline edit and sub-total automatic
I have a simple application for forecasting hours in projects for team members. The 'view' mode: For the "edit" mode I have this interface: Instead of a new view/template for "edit" I would like to have inline edit functionality. Is that feasible with Python Dango only as I don't want to use jquery or JavaScript. Similarly, can the sub-total be calculated automatically on the page just using Python Django? -
Using shell_plus doesn't import models with the same name
Let's say we have app1 and app2 that both have models MyModel. When using the console, I've noticed that app1's MyModel is the only one that is imported: python manage.py tenant_command shell_plus The above command only imports the first MyModel, and I'm assuming it doesn't do the second since there's already a MyModel imported. Is there anyway to deal with the above? Thanks I've tried to use import as but that doesn't seem to work and causes issues in a larger codebase. I can get around this by manually importing the model, but that will overwrite the one that's already imported within shell_plus -

Django - New object is not created if html action argument is provided
I have simple contact form: <form method="post"> {% csrf_token %} {{ form_email.as_div }} {{ form_message.as_div }} <button name="submit">Send</button> </form> When text is provided in both fields (email and message) and then the user click on submit button, the data should be saved in data base. View function: def index(request): """The home page.""" # Send a message. if request.method != 'POST': # No data submitted; create a blank form. form_email = EmailForm() form_message = EmailMessageForm() else: # POST data submitted; proecess data. form_email = EmailForm(data=request.POST) form_message = EmailMessageForm(data=request.POST) if form_email.is_valid() and form_message.is_valid(): form_email.save() email = Email.objects.last() message = form_message.save(commit=False) message.email = email message.save() # Display a blank or invalid form. context = {'form_email': form_email, 'form_message': form_message} return render(request, 'home/index.html', context) Until now everything works as expected, but when I add action argument in order to redirect the user to the 'Thank you' page if form has been sent, the data is not saved. <form action="{% url 'home:contact_thank_you' %}" method="post"> {% csrf_token %} {{ form_email.as_div }} {{ form_message.as_div }} <button name="submit">Send</button> </form> Do you have any idea why the data is not saved when I add the action argument?
