Django, a high-level Python web framework, is renowned for its simplicity and flexibility in building web applications.
When it comes to database integration, Django supports various database engines, and MySQL is one of the most popular choices. This blog post will guide you through the process of connecting Django to MySQL, ensuring a smooth and efficient interaction between your web application and the database.
Before diving into the configuration, make sure you have the following prerequisites in place:
Django Installed: Ensure Django is installed on your system. If not, you can install it using the following command: pip install django
MySQL Server: Have a MySQL server up and running. Install MySQL if it's not already installed on your machine.
MySQL Connector: Install the MySQL client library for Python. You can do this using the following command: pip install mysqlclient
Once you have the prerequisites in place, follow these steps to configure Django to use MySQL as its database engine:
If you haven't already created a Django project, use the following command:
django-admin startproject yourprojectname
Replace yourprojectname with the desired name for your Django project.

How to Connect Django to MySQL
Navigate to the settings.py file within your Django project. This file contains various configuration settings for your project.
Locate the DATABASES setting in the settings.py file. By default, it is usually set to use SQLite. Update it to use MySQL by replacing the following settings:
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / "db.sqlite3", } }
with:
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'yourdbname', 'USER': 'yourdbuser', 'PASSWORD': 'yourdbpassword', 'HOST': 'localhost', 'PORT': '3306', } }
Replace 'yourdbname', 'yourdbuser', and 'yourdbpassword' with your desired MySQL database name, username, and password, respectively.
Now that the settings are updated, apply the initial database migrations:
python manage.py migrate
This command creates the necessary database tables based on your Django models.
If you want to manage your Django application through the admin interface, create a superuser:
python manage.py createsuperuser
Follow the prompts to set up a superuser account.
Congratulations! You have successfully connected Django to MySQL.
Your web application can now seamlessly interact with a MySQL database, providing a robust foundation for storing and retrieving data. Explore Django's powerful features in combination with MySQL to build dynamic and scalable web applications. Happy coding!
