Django MySQL - correct way to connect
I have been using Django to connect to MySQL on my local computer and I have been using the following method to connect: run pip install mysqlclient and update the requirements.txt file appropriately. update the database connection in settings.py to something like this: 'ENGINE': 'django.db.backends.mysql', 'NAME': ......, 'USER': ......, A bit of a problem arose when I started to use a Dockerfile to try to run the Django app. When I build the Dockerfile and then run the django project, I start to get errors: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. Did you install mysqlclient? It seems to me that there are 2 potential solutions to this: 1 ) Adjust the Dockerfile so that it installs the software necessary for mysqlclient. This is actually a bit trickier than expected. Could you please make some recommendations for python:3.10.0a5-alpine3.12. 2 ) I was reading about mysql-connector-python. At present I have not got this to work. I installed it using pip, updated the requirements file and then changed the settings.py file to something like this: 'ENGINE': 'mysql.connector.django', 'NAME': ...., 'USER': ...., I have two area's of concern and I would really appreciate some help: 1 ) Which of these methods is the most appropriate … -

Django REST API refusing connection to browsers?
I tried accessing my Django project fro another device, and it always returns either ERR_CONNECTION_REFUSED on Chromium based browsers, or CORS on Firefox. I can access the API using Postman without issues. It also works if it is using localhost. Django serves HTML files no problem, just not the API calls. I've installed django-cors-headers and added it to installed applications, middleware, and allowed all. Requests don't show on console either (using manage.py runserver).

How to retrieve related instances without FK using one query in django
Imagine there are three models named Movie, Actor, and Participation. class Movie(models.Model): identifier = models.CharField() class Actor(models.Model): name = models.CharField() class Participation(models.Model): movie_identifier = models.CharField() actor = models.ForgeinKey(Actor, on_delete=models.CASCADE) Let's assume that I can't use ForgeinKey for the movie in the Participation model. how can I retrieve all the participation records of a movie with only one query? Here is the solution if I had a foreign key for the movie in the participation table: qs = Movie.objects.filter(identifier="an_identiier").prefetch_related("participations_set") How can I do this without having a Movie foreign key in the Participation model?

Django filter comparing DateTimeField with today's date does not work

What is the best way to validate fields when multiple fields follow same validation?
I have 5 fields which follow same validation in serializer. Suppose those fields are a, b, c, d, and e. Writing same validation in all 5 fields results in duplication of code. I want to avoid that. Now I have created a simple function validateFields that is called from validate_a, validate_b, validate_c, validate_d and validate_e. But django is showing this error : name 'validateFields' is not defined. How can I avoid this error? Also is there any better way than this to avoid duplication of data? -

Django: load JavaScript function to HTML Template
I have tried my JavaScript function in the Console and it seems to be working, but whenever I try to write it in my js file and load it on the index page it doesn't work. index.js document.querySelector('#post-form').onsubmit = function() { const post = document.querySelector('#post-body').value; alert(`Hello, ${post}`); console.log(post); }; index.HTML {% extends "network/layout.html" %} {% load static %} {% block body %} {% if user.is_authenticated %} <div id="post-view"> <h3>New Post</h3> <form id="post-form"> {% csrf_token %} <textarea class="form-control" id="post-body" placeholder="Post"></textarea> <input class="btn btn-primary" type="submit" value="Post"> </form> </div> {% endif %} {% endblock %} {% block script %} <script src="{% static 'network/index.js' %}"></script> {% endblock %}
