How can I send a PDF from Python to PHP?
I try to create a PDF file in Python and send it to PHP. When I open the PDF it's corrupted. Python code: from reportlab.pdfgen import canvas from io import BytesIO from django.http import HttpResponse def generar_pdf(): buffer = BytesIO() c = canvas.Canvas(buffer) c.drawString(50, 50, "¡Hola, mundo!") c.save() pdf_bytes = buffer.getvalue() return HttpResponse(bytes(pdf_bytes), content_type='application/pdf') pdf_response = generar_pdf() print(pdf_response) PHP code: <?php $pdf_bytes = shell_exec("python prueba.py"); header('Content-Type: application/pdf'); header('Content-Disposition: inline; filename="archivo.pdf"'); echo $pdf_bytes; ?> I got: An error occurred while loading the PDF document. -
django-channels integration tests with pytest?
I am trying to create a simple live-server style test fixture for pytest for testing with django-channels. I came up with the simplest solution: import pytest @pytest.fixture(scope="function") def channels_live_server(request): from channels.testing import ChannelsLiveServerTestCase class MyChannelsLiveServerTestCase(ChannelsLiveServerTestCase): @property def url(self): return self.live_server_url server = MyChannelsLiveServerTestCase() server._pre_setup() yield server server._post_teardown() When used, the web server starts in the background and serves the web pages just fine... except it is using "production" settings, which means the database used is NOT the test database. Any ideas how to fix this? I do realize, that multiprocessing at some later stage is using Popen and starts the server using spawn context. I am on macOS, if that matters. -

Django REST ModelViewSet view returns 404 after PATCH
I have ModelViewSet view in django rest framework project. I am trying to filter documents that are not live, I mean are not on main view. To filter I am using params: http://localhost:8000/documents?is_live=false. I have list of records.

how should index.html be served with django gunicorn and nginx?
my webapplication entirely dockerized and is written with a django and gunicorn backend and an nginx frontend. nginx is needed as a proxy and to serve static files. nginx has access to the static files via mounted volume from django. I would like the entire frontend not as django templates. i'm not understanding if index.html can be directly managed by nginx like this first configuration. (first nginx.conf) or if the request should regardless firstly reach django and then, ascertained that the wanted file is a static file (index.html), be redirected with the url changed in /static/... so that can be caught by nginx. (second nginx.conf). Thanks for everyone that will eventually help me. Sorry if maybe my question is born out of ignorance and please feel free to teach me if needed. server { listen 443 ssl; bash Copy code # SSL/TLS configuration ssl_certificate /etc/ssl/certs/server.crt; ssl_certificate_key /etc/ssl/private/server.key; # Define the location of static files location / { root /var/www/html/static/; index index.html; } location /api/ { include proxy_params; proxy_pass http://backend:8000; } location /static/ { alias /var/www/html/static/; } } server { listen 443 ssl; bash Copy code # SSL/TLS configuration ssl_certificate /etc/ssl/certs/server.crt; ssl_certificate_key /etc/ssl/private/server.key; # Define the location of static files location … -

Issues in Debugging a Dockerized Web App in VS Code

Django-crontab in a docker container: how to change cron working directory from "root" to "app"?
I am developping a django app relying on a mysql database. I am trying to schedule a django-crontab task to backup my database once a week (here every minute for testing). I need my app to work inside docker, I thus have one container running the app, and one container running the cronjob, both from the same image. When testing my django-crontab task in docker, by setting the command in my docker-compose to: command: python manage.py crontab run {taskhashid} the job successfully runs once and the container exists. So far so good. To run my job periodically in the forground of my container, I have changed the command to: command: cron -f. My task is here executed from "root" directory and always fails as the needed scripts are saved in "app" directory: # cat /var/log/cron.log The badge files are not found Current working directory: /root Contents of the current working directory: - .bashrc - .profile - .cache - .wget-hsts My dockerfile: # Use the official Python base image FROM python:3.8 ENV PYTHONUNBUFFERED 1 RUN pip install --upgrade pip # Install necessary dependencies RUN apt-get update && apt-get install -y \ default-mysql-client \ cron \ gcc \ python3-dev \ default-libmysqlclient-dev # … -

Django Admin Validate across normal fields and inlines
I have a model like with two ManyToMany relations and an corresponding admin class: The first relation included in "filter_horizontal" The second relation is an inline that is included in "inlines" Everything works fine as long as I don't need to add custom validation. When trying to implement a "check" method on the Model itself, the data for the inline model admin is not included. But I need access to the data from both relations at the same time. How can this be done? -
How to handle large task_kwargs in Celery to avoid ellipsis in TaskResult
I am using Celery for asynchronous task processing in my Django application. Some of my tasks involve handling large amounts of data passed as task_kwargs. However, I have noticed that when the task_kwargs are too large, the TaskResult shows the data with an ellipsis (...), indicating that the full data is not being stored or displayed. Here’s an example of what my task arguments look like: task_kwargs = { 'period': {'ydpedid': 50, 'period': 2, 'year': 2024}, 'sector': '1', 'routes': [ {'yddiaid': 1, 'code': '0102', 'descr': '0102'}, {'yddiaid': 5, 'code': '0104', 'descr': '0104'}, # Many more routes... ], 'user_id': 12345 } When I check the TaskResult, it shows the task_kwargs like this: "{'period': {'ydpedid': 50, 'period': 2, 'year': 2024}, 'sector': '1', 'routes': [{'yddiaid': 1, 'code': '0102', 'descr': '0102'} #more routes , ...}]}" the total length of task_kwargs is 1031 I am looking for a way to ensure that the entire task_kwargs is stored and visible in the TaskResult without truncation. Is there a specific configuration option I am missing or a recommended approach to handle large task_kwargs in Celery? -

Invalid HTTP_HOST header for Django app that is running in Cloud Run
I have a Django app running in Cloud Run. Cloud Run is configured as a backend service for External Application Load Balancer. The service works with different custom domains. The list of domains is changing continuously, so the domain management was moved to the Cloud Armor security policy level to avoid re-deploying the service after updating the domain list. On the Django level, all hosts are allowed: ALLOWED_HOSTS = ["*"] example.net is allowed by Cloud Armor security policy and every request to that host is handling by Django app in the Cloud Run. I started receiving requests from some scanning bots and some of this requests cause an error on the Django app level: Invalid HTTP_HOST header: 'mydomain.com%7d'. The domain name provided is not valid according to RFC 1034/1035. Here are other values from the traceback for this error: Report at //example。com Invalid HTTP_HOST header: 'example.net%7d'.

How to mapping ForeignKey model value in Django Rest Framework
models.py class Item(models.Model): name = models.CharField(max_length=100) # other_no_need_translate = models.CharField(max_length=100) class Itemi18n(models.Model): origin = models.ForeignKey(Item, related_name='i18n') language = models.CharField(max_length=200, default="") name = models.CharField(max_length=100) view.py class ItemViewSet(viewsets.GenericViewSet): def get_queryset(self): return Item.objects.annotate(name=F('i18n__name')) # something like this serializers.py class I18nField(Field): def __init__(self, field_attr, **kwargs): self.field_attr = field_attr super().__init__(source='*', read_only=True, **kwargs) def to_representation(self, value) -> str: request = self.context['request'] if request.query_params.get('lang') == 'es': value = ... else: value = ... return value class ItemSerializer(serializers.ModelSerializer): name = I18nField(...) I want to write a serializer, when i18n is needed, return name from Itemi18n, otherwise return name from Item. I thought of 2 solutions，one is use annotate to override field, another is use Custom Field. I am not sure about best practices and performance issues.
