Django, DRF, nginx, Jmeter: Sample Time becomes large even though there is no load on the CPU, etc
I am using Jmeter to load test the DRF, and even though the CPU and memory are not at 100%, the throughput and response time is slow. The Django + nginx and Postgres servers are separated, and both have the following specs 4CPU, 4GB memory. nginx is using docker's https-portal as shown below. version: "3" services: https-portal: image: steveltn/https-portal:1 ports: - "80:80" - "443:443" environment: DOMAINS: "my.domain.com -> http://backend:8000" STAGE: "production" volumes: - https-portal-data:/var/lib/https-portal - ./nginx/uwsgi_params:/etc/nginx/uwsgi_params - ./static:/static depends_on: - backend restart: always backend: build: . command: uwsgi --http :8000 --module privatine.wsgi --processes 4 volumes: - .:/usr/src/app - ./static:/usr/src/app/static expose: - 8000 env_file: - .env - .env.prod restart: always volumes: https-portal-data: Looking at the django logs, there doesn't seem to be anything wrong with django, what do you think could be causing this? generated 8302 bytes in 29 msecs (HTTP/1.0 200) 7 headers in 208 bytes (1 switches on core 0) Setting up Jmeter: Django + nginx server: DB(postgres) server: After 5 minutes of continuous loading.

What's the correct way to use helpers to extend functionality in Django models?
I'm adding some extended functionallity to my models in Django. In order to not overload the model root interface (and file), i'm using some helpers as attributes of the model. What i want is to group the methods and properties into this helpers, and what i want is something like: class Product(models.Model): downloads = DownloadsHelper() # .... pass p = Product.objects.first() p.downloads.files_count(p) p.downloads.reset_permissions(p) # ... In order to not to have to pass the instance to the helper each time, I could use another approach. class Product(models.Model): def __init__(self, *args, **kwargs): super(Product, self).__init__(*args, **kwargs) self.downloads = DownloadsHelper(self) self.shipping = ShippingHelper(self) p = Product.objects.first() p.downloads.files_count p.downloads.reset_permissions() And finally, a more python-generic/conceptual way to do this stuff would be like: class Helper: def __init__(self, helped): self.helped = helped class Helper1(Helper): attribute_name = 'helloing' def hola(self): print("hola") class Helper2(Helper): attribute_name = 'goodbying' def chau(self): print("chau") class Helped: def __init__(self): self._install_helpers() def _install_helpers(self): for helper in self.helpers: setattr(self, helper.attribute_name, helper(self)) class MyHelped(Helped): helpers = [Helper1, Helper2] h = MyHelped() h.helloing.hola() h.goodbying.chau() And the question is: Is this last approach a correct way /good practice to do the stuff from a pythonic-OOP and "Djangoid" point of view. Has this any problem? Thanks for reading! -
Test database for Django + Heroku. Error creating the test database: permission denied to create database
I'm trying to run the tests for my Django project. I wrote this project some time ago, I had different settings then and tests were passing. Now I changed settings and deployed it on Heroku with Heroku Postgres database. Everything works fine already except I can't run tests. I've tried many different settings and nothing worked. Most of the time I'm getting this error: permission denied to create database My last setting is following the instruction from this article on medium Basically I have added 2nd Heroku Postgres database, add settings like below (but with valid variables of my heroku databases): if 'test' in sys.argv: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'd7osdssadag0ugv5', 'USER': 'lhwwasadqlgjra', 'PASSWORD': '1524f48a2ce41177c4ssdadasd3a11680b735302d14979d312ff36', 'HOST': 'ec2-54-75-2326-118.eu-west-1.compute.amazonaws.com', 'PORT': 5432, 'TEST': { 'NAME': 'd7osdssadag0ugv5', } } } else: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'd7hasadas9hqts5', 'USER': 'nybkduadsdgqot', 'PASSWORD': 'bb535b9cdsfsdfdsfdsfac54851f267444dd8cc230b2a786ab9f446', 'HOST': 'ec2-54-247-132-38.eu-west-1.compute.amazonaws.com', 'PORT': 5432, 'TEST': { 'NAME': 'd7hasadas9hqts5', } } } Then run python manage.py test --keepdb in my venv.

Passing Django variable to an accordion attribute in HTML
I am newbie to Django and apologize in advance for such a basic question to most of you, but I looked for similar questions all over and haven't encountered a workable solution. I am trying to create a Bootstrap Accordion for each item of a Django for-loop. So a list of items is displayed, and when you click on one item, the description of it will collapse to show. The segment currently looks like this using this template: <head> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script> </head> <body> {% for item in items %} <div class="accordion" id="accordionExample"> <div class="accordion-item"> <h2 class="accordion-header" id="headingOne"> <button class="accordion-button" type="button" data-bs-toggle="collapse" data-parent="#accordion" data-bs-target="#collapseOne" aria-expanded="false" aria-controls="collapseOne"> {{ item }} </button> </h2> <div id="collapseOne" class="accordion-collapse collapse" aria-labelledby="headingOne" data-bs-parent="#accordionExample"> <div class="accordion-body"> {{ item.description }} </div> </div> </div> </div> </body> Now, this is giving the same value (collapseOne) to data-bs-toggle, aria-controls and id of accordion-collapseclass(collapsing element) for every for-loop item, resulting in all the accordion items collapsing when one of them is clicked though I want only the clicked one to collapse. So I tried to pass the Django variable as such: {{ item }} in place of collapseOne {{ forloop.counter }} in place of collapseOne The … -
db.sqlite3 continues working after having been deleted
I recently deleted my db.sqlite3 file because some data had become corrupted. I though that at the next run of python manage.py migrate it would have simply been recreated from stratch. Instead, Django is contuining to work off the old db.sqlite3 despite the file not existing anymore - I assume it's somehow cached? Specifically: python manage.py migrate works fine but it doesn't create a new db.sqlite3 file. There is no db.sqlite3 file anymore in my root. I already manually deleted all migrations. The app continues to work okay with all the previous data still there (e.g., users). In case it's useful, I'm coding on Replit. -
Is it impossible upload file in the different region from the region of s3 bucket? (IllegalLocationConstraintException)
I deployed my django project using AWS Elastic beanstalk and S3, and I tried to upload the profile avatar but it shows Server Error(500) My Sentry log shows me, "An error occurred (IllegalLocationConstraintException) when calling the PutObject operation: The eu-south-1 location constraint is incompatible for the region specific endpoint this request was sent to." I think this error appeared because I put my bucket on eu-south-1 but I try to access it and to create a new object in Seoul, Korea. Also, the AWS document said IllegalLocationConstraintException indicates that you are trying to access a bucket from a different Region than where the bucket exists. To avoid this error, use the --region option. For example: aws s3 cp awsexample.txt s3://testbucket/ --region ap-east-1. (https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html) but this solution might be just for when upload a file from AWS CLI... I tried to change my bucket policy by adding this but doesn't work. { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": "*", "Action": "s3:PutObject", "Resource": "arn:aws:s3:::{BucketName}/*" } ] } I don't know what should I do and why they do not allow access from other regions? How to allow access to create, update and remove an object in my bucket from all … -

I am working on a project using Django and i need to send a soap request but i have to sign it using a 'JKS' file and it's password and alias. I've tried working with suds and zeep packages. But I can't find any example in python to help me understand how to do that. Can some one help me? -
Elastic Beanstalk Django app deployment 502 Bad Gateway Server not running (No module named: 'application')
I deployed an application to AWS via Elastic Beanstalk, and when I finished pushing the project to aws (Elastic Beanstalk), I am faced with perpetual 502 Bad Gateway errors (probably because the Django app server never actually started, and Nginx can't proxy us through). Looking at the logs, I found a weird error that seems very specific, and erroneous. It looks like so: Traceback (most recent call last): Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/arbiter.py", line 589, in spawn_worker Dec 13 09:00:10 ip-172-31-35-65 web: worker.init_process() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/workers/gthread.py", line 92, in init_process Dec 13 09:00:10 ip-172-31-35-65 web: super().init_process() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/workers/base.py", line 134, in init_process Dec 13 09:00:10 ip-172-31-35-65 web: self.load_wsgi() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/workers/base.py", line 146, in load_wsgi Dec 13 09:00:10 ip-172-31-35-65 web: self.wsgi = self.app.wsgi() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/app/base.py", line 67, in wsgi Dec 13 09:00:10 ip-172-31-35-65 web: self.callable = self.load() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/app/wsgiapp.py", line 58, in load Dec 13 09:00:10 ip-172-31-35-65 web: return self.load_wsgiapp() Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/app/wsgiapp.py", line 48, in load_wsgiapp Dec 13 09:00:10 ip-172-31-35-65 web: return util.import_app(self.app_uri) Dec 13 09:00:10 ip-172-31-35-65 web: File "/.../python3.8/site-packages/gunicorn/util.py", … -
Django DATABASES settings
I understand if you connect to your MongoDB database via pymongo, you should remove the DATABASES section in your settings.py file, which I have done, but I get this: django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Apparently, pymongo does not replace a relational database with MongoDB. It is simply a facility allowing you to access a MongoDB in addition to your regular database; meaning I still need my databases settings... I know my connection string and database name and collection name, but what should the DATABASES section look like in my settings.py file? On https://docs.djangoproject.com/en/2.0/ref/settings/#databases and a few other posts and articles, only settings for sqlite3 and postgresql and mysql and oracle are mentioned. I cannot seem to find the right setting for 'ENGINE': 'django.db.backends.mongodb' How can I use a MongoDB database then? What goes in the xxx.backends.xxx section? -
What is the proper method to pass data in class-based django views?
I'm looking for a proper or a basic method to pass the result of a filter in a class to another page which is in another class and temporarily use it for a purchase class home(View): def get(self, request): return render(request,'home.html') def post(self, request): # rm = room.objects.all().filter(#filter) class results(View): def get(self, request): rm #from home return render(request,'result.html',{'rm':rm}) def post(self, request): #
