Django: can't load images but static files OK
I'm learning Django, and I've spent a week+ trying to display images in my app. I think that there's an issue with my settings but I'm perplexed since the static files are loading, though the images with similar settings are not. What confuses me so much is that my static files are loaded ok at MEDIA_ROOT/static, but that image files aren't found at MEDIA_ROOT/media. Based on settings.py, static seems like it would live at # C:\Users\...\final\static but it's clear that this isn't true. structure ├── final │ ├── dogtracks │ │ ├── static | │ │ ├── dogtracks │ ├── media | │ ├── images settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') ... MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') # C:\Users\...\final\media models.py class Animal(models.Model): ... photo = models.ImageField(upload_to='images', null=True, blank=True) ... class AnimalForm(ModelForm): class Meta: model = Animal fields = ['name', 'breed', 'species', 'birthday', 'photo'] html {% if pet.photo %} <img src="final{{ pet.photo.url }}" /> {% else %} <img src="{% static 'dogtracks/noun-pet.png' %}" /> {% endif %} I've read dozens of answers here on SO and gone through tutorials online. I've moved the location of my images folder to try to show these images. -
Python requests script with proxies does not work in Docker container on Windows
I have Docker installed on both Windows and Linux, and I have a dockerized Django app running on both operating systems. When I execute this script in the Django shell on Linux, it correctly returns the IP of the proxy server, as expected. However, when I run the same script on Windows, it returns my external IP address instead. import requests request = requests.get(url='https://httpbin.org/ip', proxies={ 'http': proxy_url, 'https': proxy_url, 'socks5': proxy_url }) print(request.text) Has anyone encountered a similar issue? -
Django ManifestFileStorage STATIC_ROOT misconfigured
I recently upgraded my project from Django 2.2.28 to 3.2 and am using Django-storage 1.14.2. As part of the upgrade, I replaced CachedFileMixin with ManifestFileStorage. Before the upgrade, everything was functioning correctly, and I haven't altered any other settings. However, I've run into an issue where self.location seems to cache a None value and it doesn't change. I found a temporary workaround by deleting the cache, which resolves the problem. Has anyone else experienced this or have any ideas on why this is happening? Code Snippet: class StaticFilesStorage(ManifestStaticFilesStorage, S3Boto3Storage): def __init__(self, *args, **kwargs): S3Boto3Storage.__init__(self, bucket_name=settings.STATIC_FILES_BUCKET, custom_domain=domain(settings.STATIC_URL), *args, **kwargs) ManifestStaticFilesStorage.__init__(self, *args, **kwargs) Error Message: Error output PDB Output: PDB output in ManifestStaticFilesStorage initializing After refreshing the cached value manually the error is resolved -
Django prefetch_related with multiple filters
Lets say this is my hypothetical codebase: class Address(models.Model): country = CountryField() ... class Location(models.Model): address = models.ForeignKey(Address, on_delete=models.CASCADE) class Zoo(models.Model): location = models.ForeignKey(Location, on_delete=models.CASCADE, related_name="zoos") class Animal(models.Model): name = CharField(max_length=200) animal_type = CharField(max_length=200) zoo = models.ForeignKey(Zoo, on_delete=models.CASCADE, related_name="animals") def animals_of_type_at_zoo(animal_type, zoo): return zoo.animals.filter(animal_type=animal_type) def generate_report(): report_data = {} animal_types = ["lion", "tiger", "bear", ...etc] locations = Location.objects.all() locations = locations.prefetch_related("zoos", "zoos__animals") for loc in locations.all(): for zoo in locations.zoos.all(): for animal in animal_types: report_data[loc.address.country][animal] += animals_of_type_at_zoo(animal, zoo).count() return report_data My goal is to make generate_report faster using prefetching. In this case I have added locations.prefetch_related("zoos", "zoos__animals"). However, since animals_of_type_at_zoo uses a filter, it triggers another query. My thought process was to prefetch each filter: locations = locations.prefetch_related("zoos", "zoos__animals") for animal in animal_types: locations = locations.prefetch_related(Prefetch("zoos_animals", queryset=Animals.objects.filter(animal_type=animal)) However zoos_animals can only be assigned once, I can't create multiple filters for this. My goal here is to prefetch everything needed with minimal impact to the animals_of_type_at_zoo function as it is used in other parts of the codebase and I want to minimize impact on the rest of the application (testing and performance). I had attempted to create custom object that override filter and would return the correct prefetch, but wasn't getting … -

I'm getting a "Connection unexpectedly closed" whenever I try to send an email with django hosted with Cloud Run. How do I diagnose this?
In my settings.py: EMAIL_BACKEND = django.core.mail.backends.smtp.EmailBackend EMAIL_HOST = smtp-relay.gmail.com EMAIL_HOST_USER = env('EMAIL_HOST_USER') EMAIL_HOST_PASSWORD = env('EMAIL_HOST_PASSWORD') EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_USE_SSL = False the line that actually sends the mail in one of the api end points is send_mail(subject, body, email_from, recipient_list) I can confirm with logs that the user and password is correct. I also can confirm that this works locally when I run it on my local environment. The issue is when I deploy this via Google Cloud Run I'm just getting Connection unexpectedly closed with no stacktrace and no information. From the Networking tab in cloud run I have allowed all ingress and have not set up any VPC network so I don't think it's that, however because of the nature of containerizing my app I don't know what else it could really be. What else would you try to diagnose and search? -

Popen subprocess giving wrong ffmpeg process ID when trying to close
I'm trying to create a Video Management System application using React and Django, that displays live camera stream and do video recording. For this, I add cameras using POST request and everything works fine. But when I am required to update a camera's details, like IP address or password, then first I delete the camera and then create a new instance with same camera name. The problem I'm facing is that the process ID of the camera (ffmpeg instance here) is not updating, e.g. if initially the process ID was 10, then it remains 10 (in terminate() function in the code) even when I re-create the camera with new details but I do get new process ID in start() function. Below is the code: import subprocess from subprocess import Popen import os, sys import threading import time from datetime import datetime import pytz import os, signal """This class is used to create camera objects to display live stream and recordings, it is also used to manage recordings files by deleting them at the given time""" class CameraStream: def __init__(self, device_name, username, password, ip_address, storage_days): self.cam_name = device_name self.username = username self.password = password self.cam_ip = ip_address self.storage_days = storage_days self.p1 … -
How to Query If An Instance Exists Within A Many-To-Many Field On Django Queryset
Here are simplified model definitions class Resource(models.Model): name = models.CharField(max_length=100, unique=True) class Location(models.Model): name = models.CharField(max_length=100, unique=True) resources = models.ManyToManyField(Resource) And I want to know for one type of Resource, the existence on each Location. So the json data I want is like [ { "id": 1, "name": "loaction_A", "resource": true }, { "id": 2 "name": "location_B", "resource": false }, ... ] I tried following view function but obviously got wrong results. def resource_view(request, res_id): res = get_object_or_404(Resource, pk=res_id) locations = Location.objects.values('id', 'name')\ .annotate(resource=Q(resources=res)) return JsonResponce({'locations': list(locations)}) I know I need something like below (in SQL) select app_location.*, 1 in ( select resource_id from app_location_resources where location_id = app_location.id ) as resource from app_location How should I construct the queryset? -
Is the Use of Django Templates Common in Backend Python Jobs, or is it Typically Used Primarily for API and Business Logic Development?"
In the job market, I see many Python backend positions, and many of them require knowledge of the Django framework. However, as I started studying Django, I noticed that it uses templates as part of its architecture. In practice, are templates heavily used, or do companies typically have a frontend person using some JavaScript framework and a backend person using Django more for building APIs and implementing business logic? me as a Backend developer should focus in learn templates or learn build api in django with django rest? I'm new to Django and exploring backend Python job opportunities. I've noticed that Django uses templates in its architecture, but I'm curious about the practical use of templates in the industry. Have you encountered a situation where Django templates are widely used in backend development roles, or is it more common for companies to have a frontend specialist using JavaScript frameworks while Django is primarily utilized for API development and business logic implementation? -

Django APIView returns “IndexError: list index out of range” in unit test but works in Postman
I have written an APIView in Django that returns a random line from a database table. When I test it using Postman, I get the response I want. However, when I call the URL of the endpoint in a unit test, I get an “IndexError: list index out of range” error.

Access to related model field in django_filters
I'm constructing Django-based 4-language website for a real estate agency. I'm using django-filter package to filter my objects (real estate properties) by certain parameters, such as type (house, apartment, etc.), city and some others. My 'type' field is a foreign key for the model 'Type'. On the html page this field is tendered as a field with options, which is good. But for some reason the options are rendered as slug names of my types ('house', 'apartment', etc., see the picture). It is the 'slug' field of my foreign key model Type. Instead of this, I want to print 'name' field in the options. This field is translated (django-modeltranslation package), so that in English version one should see options 'House', 'Apartment'..., and in Spanish version - 'Casa', 'Apartamento', etc. I tried modify this field in my PropertyFilter as using '__' symbol (type__name instead of type), but it doesn't seem to work. Please, help me, I'm stuck! -

How to manage serializers in Django Rest Framework?
I use the following serializer in my ViewSet to create some Instance: class InstanceCreateSerializer(ModelSerializer): class Meta: model = Instance fields = [ "id", "name", "description", "company", "err_msg", "is_valid", ] The fields author, company, is_valid and err_msg must be set by the service, not by the user. But if i use read_only_fields, as in the code below, then these fields cannot be changed by the service either. class InstanceCreateSerializer(ModelSerializer): class Meta: model = Instance fields = [ "id", "name", "description", "author", "company", "err_msg", "is_valid", ] read_only_fields = [ "author", "company", "err_msg", "is_valid", ] How can I manage serializers or prevent the user from submitting values for these fields? Additionally, these fields are available for input in the DRF Browsable API and Swagger, which is something I also want to fix. -
