Why is google console shows anchor text as URL Django Template instead of actual text?
I have deployed a website using Django (https://www.pkelection.com/). This is my very first app so still trying to learn.

Unit testing with AWS Cognito and GraphQL
I'm currently writing tests for my software but got stuck at the point. I try to get data from my db with a normal GraphQL Query but my endpoint is first checking, if the idToken within the header is valid. For the user handling I'm using AWS Cognito but couldn't find a good way to mock the login to retrieve the valid token to query and mutate the data within various endpoints. Any idea how to handle this case? Here is my code from the graphene docs (https://docs.graphene-python.org/projects/django/en/latest/testing/): # Create a fixture using the graphql_query helper and `client` fixture from `pytest-django`. import json import pytest from graphene_django.utils.testing import graphql_query # https://docs.graphene-python.org/projects/django/en/latest/testing/ @pytest.fixture def client_query(client): def func(*args, **kwargs): return graphql_query(*args, **kwargs, client=client) return func # Test you query using the client_query fixture def test_some_query(client_query): response = client_query( ''' query GetAllProjectConfig{ getAllProjectConfig{ project{ id slug name } config{ id } } } ''', ) content = json.loads(response.content) assert 'errors' not in content -

Individual product detail pages with django cms
I have an e-commerce app based on Django. The product model contains basic fields like name, brand, short description, etc. So far, I only have a "generic product detail page" that displays these information for each product. Now I want to create more extensive product detail pages for some of the products with django cms so that they contain more product information and seo keywords. This means that most products would just have the "generic" detail page and some have a more extensive version. I am using a url path like mydomain.com/products/ and the view finds the respective product to be displayed using the product-slug. So far, this "/products/..." path is handled outside of the django-cms url namespace. I am rather new to django cms and unsure how I should handle this project. My first idea would be: Add empty django-cms placeholders to the generic detail page Include the /products/... path in the django-cms namespace Run a script that creates a page in django-cms for each individual product (whenever a new product is added to the database, a new django-cms page must then be added as well programatically) Go to the products of high interest and add additional content with … -

Django oAuth2 without saving the user into the database
I'm currently coding a website with Django and I successfully implemented an external oAuth2. (I'm not using any libraries) the problem is that the user is saved in the database. I would like to avoid it for hosting costs reasons. In my current project, the oAuth2 is purely for verification purposes. Is there a way in Django to log in a user in without saving him to the database? I would like the website to keep him logged in if the page is refreshed but logged out if the page is closed. Thanks! -

Celery unavailable after dockerization in a Django app
I have a Django app that I've been trying to dockerize. I've successfully dockerized Django with gunicorn and nginx so the main part of the app is running. However, I also have tasks that need to be run using Celery. I dockerized rabbitmq, and I think that was successful, as before installing it I had Connexion refused and I don't anymore. I only lack Celery to be dockerized so, as my tasks are not executed nor stored in the database, my Celery configuration is probably wrong, however I couldn't find where I'm going wrong with it. Here is my docker-compose.yml: version: '3.8' services: django_gunicorn: volumes: - static:/app/static - media:/media env_file: - env build: context: . ports: - "8000:8000" nginx: build: ./nginx volumes: - static:/static - media:/media ports: - "80:80" depends_on: - django_gunicorn rabbitmq3: image: rabbitmq:3-alpine ports: - 5672:5672 celery: restart: always build: context: . command: celery -A main worker -l info env_file: - env depends_on: - rabbitmq3 - django_gunicorn volumes: static: media: Dockerfile: FROM python:3.10.5-alpine RUN pip install --upgrade pip RUN wget https://upload.wikimedia.org/wikipedia/commons/b/b9/First-google-logo.gif -O media/media.gif COPY ./requirements.txt .

I am trying to create an app that uses the Django REST Framework and Flask, but it is not working correctly
I'm having trouble with my python app using django and flask framework. It's creating a database and all of that stuff but when it tries to make a request to /api/v1/users, it always comes back with data errors.
