I can access mysql on the this 'other' machine.
Can someone help me get the project running?
EDIT:
my database section in settings.py
DATABASES = {
'default': {
'ENGINE': 'mysql.connector.django',
'NAME': 'Bvink',
'USER': 'bvink',
'PASSWORD': 'XXXXX',
'HOST': 'mariadb',
'PORT': '3306',
}
}
I also get this error when i type python3 manage.py makemigrations, migrate and shell

In my web application which is being made in Django (Django==3.2), I am trying to use mysql as the Database, but in the settings.py, when I tried to give mysql as the engine :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': DB_NAME,
'HOST': DB_HOST,
'USER': DB_HOST,
'PASSWORD': DB_PASS
}
}
and then tried ruserver command, I got the following error:

django.core.exceptions.ImproperlyConfigured: 'django.db.backends.mysql' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
'oracle', 'postgresql', 'sqlite3'
do you know how I can give mysql as the engine in the settings.py? I tried the following but got the same error:
mysql.connector.django
try to install : (mysqlclient) pip install mysqlclient in order to use MYSQL as the backend for Django apps ; you will need the mysqlclient library and in your settings.py file do this :
#settings.py
DATABASES = {
'default' : {
'ENGINE': 'django.db.backends.mysql',
'NAME' : 'mydatabase',
'USER' : 'myUser',
'PASSWORD' : 'My_passowrd',
'HOST' : 'localhost',
'PORT' : '' ,
}
}
i hope it helped you
I have been using django (2.1.5) with mysql-connector(2.1.6). Suddenly it has stopped working and giving below error when i do "python manage.py runserver". I have been trying to understand the solution through other question on same issue but it doesn't seem to help.Can somebody please help.

I'm new to Django and web frameworks in general. Right off the bat, I can't seem to run the server after django-admin startproject mytestsite. I've tried this with and without a virtual environment, and with Python's built-in virtual environment tool as well as virtualenv.
This is the error I get:
