Html is not extending correctly only base.html
When trying to extend from base.html my home.html is not showing when at the url that shows home.html only the base.html is showing. I can't seem to figure out what the problem without extending my home.html shows up perfectly but when extending from base.html it seems like it doesn't want to work Base.html {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <link rel="stylesheet" href={% static 'css\base.css'%} </head> <body> <body> <nav class="navbar"> <ul class="navbar-nav"> <li class="nav-item">Home</li> <li class="nav-item">About</li> <!-- Dropdown will go here --> </nav> {% block body_block %} {% endblock %} </body> </body> </html> Home.html {% extends 'base.html' %} {% load static %} <div class="contianer"> <div class="heading">NEW RENTALS</div> {% for List in listings %} <div class="items"> <img src="{% static List.itempicture %}" alt="" /> <div class="Info"> <h1>{{List.title}}</h1> <p>{{List.about}}</p> <a class="button" href="{{ List.get_absolute_url }}">Contact</a> </div> </div> {% endfor %} </div> <link rel="stylesheet" href={% static 'css\home.css'%} -
Does durable Django atomic transaction imply we don't need savepoints
A Django atomic transaction has the durable and savepoint arguments. See docs. durable=True ensures the atomic block is the outermost atomic block. Per the docs: It is sometimes useful to ensure an atomic block is always the outermost atomic block, ensuring that any database changes are committed when the block is exited without errors. This is known as durability and can be achieved by setting durable=True A PostgreSQL SAVEPOINT establishes a new savepoint within the current transaction. Sounds like this is only needed if the atomic block is nested. I have the following questions: If durable=True then savepoint should ALWAYS be False, right? Because there's no point in using a savepoint if the atomic block is the outermost atomic block. If durable=True, should Django set savepoint=False for us? Reading through the source code, it doesn't appear to do it for us but I feel like it should. -

Docker + Django if_debug template tag is not working
I am running a docker-compose with nginx routing requests to my Django server, with this config: upstream django { server backend:8000; } server { listen 80; location / { proxy_pass http://django; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } } To use the {% if debug %} template tag I know I need both the correct internal IP and the DEBUG setting turned on. I get the correct internal IPs by running the following code snippet in my Django settings.py: import socket hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS = [ip for ip in ips] + ['127.0.0.1'] When I docker exec -it backend sh, and import the DEBUG and INTERNAL_IPS settings, I get that the values are ['172.19.0.4', '127.0.0.1'] and True, respectively. Then, when I run docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq) to check the containers' IP address, I see that the backend container that runs Django has an IP of 172.19.0.4, same as the internal IP. Despite this all, in the Django template, I get a Django debug mode error (further proving that debug is turned on) that says that an error got triggered on line 61!!! 57 {% if debug %} 58 <!-- This … -

How do I implement user authentication in Django using rest_framework?
I'm using Django/Python3 to make a simple API. I already made my models and views (also using serializers). Currently this is my login view: class LoginView(generics.CreateAPIView): queryset = User_Login.objects.all() serializer_class = LoginUserSerializer def post(self, request, *args, **kwargs): id = request.data['id'] name = request.data['name'] password = request.data['password'] email = request.data['email'] User_Login.objects.create(id=id, name=name, password=password, email=email) return HttpResponse({'message': 'User Created', 'id': id}, status=200) All my views are basic like this, just to implement a database that I previously modeled. I need to implement authentication (the one that generates simple tokens that the user need to add to their request's header) and I know It's easy, but I followed this tutorial and I got a lot of errors. Any advice? -

I'm wondering which option is better ,I personal prefer isolating these 2 projects.There are 2 reasons: 1.I have no experience to combine Scrapy with Django. 2.Lower the risk, if one die another one can still alive.

Django, MySQL, and SSL certs: strings instead of filenames?
I'm attempting to configure a Django application to connect to a MySQLDB instance with TLS configured. Django's DATABASES settings documents how to configure the ssl settings, for eg.: DATABASES = { 'default': { 'ENGINE': os.environ.get('DATABASE_ENGINE', 'django.db.backends.mysql'), 'HOST': os.environ.get('DATABASE_HOST'), 'PASSWORD': get_vault_secret('DATABASE_PASSWORD'), ... 'OPTIONS': { 'ssl': { 'ca': '/ca/server.cert.pem', 'cert': '/ca/client.cert.pem', 'key': '/ca/client.key.pem' } } }, } Our problem is that the values required for ca, cert, and key are filenames. Our app is containerized, and we pull all of our secrets from hashicorp Vault during app initialization using a helper func (see the value for PASSWORD). We also store client certs, keys, etc in vault, and would like to supply these to Django directly - but MySQL demands a string, pointing to a file. Is there a way to wrap the cert / ca / key strings we get from vault into some kind of IOFile / BytesIO esque container to pass from Django, to python mysqlclient, to mysql_ssl_set()? Due to security considerations, actually writing these values to a file is not an option. -
