Docker container Losing all file when start from cache
I am trying to create a Dockerfile for developing Django backend. However, when I finished my Dockerfile and tried to build it, a very strange error occurred. When my container was successfully built and automatically started, all the files I had copied into it were lost. Container build log Container log I try to change the CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"] to CMD ["python"] and used ls check the file, its empty. file check Then I found the last cache and used it to generate a container, and found that the process worked perfectly fine, which was the most peculiar part. Container from cache working fine Environment I'm using: Windows 11 Docker for windows v4.17.1 PyCharm 2023.1 (Professional Edition) Configuration setting Docker setting configuration setting I don't know if this is a problem with my Dockerfile or a bug with Docker, but since I need to provide my team with a Docker to complete our task, I hope to solve this problem and enable my team to build containers correctly from the Dockerfile. -

Django update_or_create() from JSON when key may or may not exist
So i am create a function where data is being pushed to models from the JSON file. There is a possibility that my JSON may or may not have the desired key. but i am not sure how can i pass default value such as N/A if key not existed. Sample JSON: Here 1st object have title key and 2nd does not h {"timestamp":"2023-04-20T15:45:53.085646251+05:30","status_code":200,"content_length":17620,"failed":false, "title":Test Website} {"timestamp":"2023-04-20T15:45:53.085646251+05:30","status_code":200,"content_length":17620,"failed":false} Django view: data = [] for line in open(results.json', 'r'): data.append(json.loads(line)) for item in data: obj, created = http.objects.update_or_create(asset=item['input'], defaults={ 'status_code':item['status_code'], 'title':item['title'], 'last_added':datetime.now()},) This gives me KeyError('title') Can I add default value to be added only if key not existed? -
ERROR 404 (Page not found) in POST Method with Django

Django can't show Bokeh plot's through CloudFlare tunnel
Have a **Django **website that was accessed through port forwaring in the router. Django lives in an Windows server and in a happy companion with a Bokeh server. Accessing the server ip to a dedicated port gave respons and Django got nice graphics from Bokeh. So I bought a domain and accessed the Django site via a Cloudflare Tunnel, and the Django website can’t get any grapics from Bokeh anymore. How should this be configured and what is best practic for this to work well through Cloudflare. I'am stretching my skills a bit here. Anybody who can help me solve this puzzle? Best regards Jon Helge Thougth in the beginning that the problem were in Bokeh, so installed SSL to solve communication between DJango and Bokeh. Did not solve the problem Tried to find out how Django and Bokeh communicates with each other but still not seen a drawing for how exchenge of data is done between them. But if we go localhost again all is functioning again. A bit stuck om how to go further. -
django-admin returns - zsh: [PATH] no such file or directory

Setting log factory logic from outside settings.py
I have a Django application where I want to update the standard logging to structured JSON format. I can get this working fine by adding my logging config and some business logic into settings.py, but I want to keep the business logic separate. Is there any Django built-in file (akin to the settings.py) that allows you to add some logic that Django will pick up, or can I load a file with this additional logic from settings.py? Here is what I have: settings.py LOGGING = { 'version': 1, 'formatters': { 'structured': { 'format':'%(json_structured)s', 'datefmt': "%H:%M:%S" } }, 'handlers': { ... }, 'loggers': { ... } } # Below is what I want to move from settings.py class JsonDateTimeEncoder(JsonStringFallbackEncoder): def default(self, obj): if isinstance(obj, datetime): return obj.strftime('%Y-%m-%dT%H:%M:%S%z') else: return super().default(obj) std_record_factory = logging.getLogRecordFactory() def structured_log_record_factory(*args, **kwargs) -> logging.LogRecord: record = std_record_factory(*args, **kwargs) record.json_structured = json.dumps( { 'level': record.levelname, ... }, cls=JsonDateTimeEncoder, ) return record logging.setLogRecordFactory(structured_log_record_factory) I know I can load the LOGGING config from file, but not sure how best to achieve this with the additional logic. -
Annotate a QuerySet with Exists instead of Count
I have a model which contains a ManyToManyField: class UserHasProduct(Model): user = ForeignKey(User, on_delete=CASCADE) products = ManyToManyField(Product) class Product(Model): is_nfr = BooleanField(default=False) I want to annotate my queryset with a simple is_nfr value that returns True if any of the products have is_nfr set to True. The best I could come up with is this: UserHasProduct.objects.filter(user=self.request.user).annotate( is_nfr=Count("license_code_products", filter=Q(products__is_nfr=True)) ) That works, but instead of a boolean it returns an integer. Not a huge deal, but I am still wondering if it's possible to return a boolean, and if that would help with query performance in any way (i.e. it can stop as soon as it finds the first match, no idea if it works like that). -
Django CSRF verification failed after setting SSL with Certbot
I'm currently working on a Django project that utilizes Docker, and I recently set up an SSL certificate using a containerized version of Certbot in order to secure my Django app through HTTPS. However, after implementing the SSL certificate and updating my nginx configuration, I began to experience the 'CSRF verification failed' error, which was not an issue before the setup. Previously, I was able to log into my Django app when it was using HTTP. What could be the cause of this problem? My Django setting. # settings.py ALLOWED_HOSTS = ["*"] 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", ] if DEBUG: CORS_ALLOW_ALL_ORIGINS = True else: CORS_ORIGIN_ALLOW_ALL = False CORS_ORIGIN_WHITELIST = [ 'https://example.ph', ] My previous nginx configuration. upstream api { server sinag_app:8000; } server { listen 80; location / { proxy_pass http://api; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /static/ { alias /static/; } } My new nginx configuration with SSL certificate. upstream api { server sinag_app:8000; } server { listen 80; server_name ${DOMAIN}; location /.well-known/acme-challenge/ { root /vol/www; } location / { return 301 https://$host$request_uri; } } server { listen 443 ssl; server_name ${DOMAIN}; ssl_certificate /etc/letsencrypt/live/${DOMAIN}/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/${DOMAIN}/privkey.pem; include /etc/nginx/options-ssl-nginx.conf; ssl_dhparam … -

Reactjs - Axios instance - withCredentials not working
I made a view in ReactJS to edit the user profile, and started to use axios like this: //profile.js axios.post("/api/user/update/",{ withCredentials: true, username: newUsername, email: newEmail, lang: "", }).then... This is working perfectly well as the credentials are sent with the request, however when making an axios instance like that: //axiosInstance.js const API = axios.create({ withCredentials: true, baseURL: django_base_url + "/api/", }) export default API; //profile.js API.post("user/update/", { username: newUsername, email: newEmail, lang: "", }).then... The credentials are not sent with the request and I get a 403 from my django backend that says that it's missing the CSRF_TOKEN. React and Django are not running on the same url (:8000 django :3000 React), I already set the proxy to :8000 in my package.json. I also tried to force the credentials this way API.defaults.withCredentials = true; but without any success either. I am confused on why the instance doesn't work when it does without it? I'm just trying to force the credentials on every axios request. -

Django: How to also migrate the name of a Primary Key `id_seq` in PSQL database
