I work with Django projects frequently, and often find myself repeating the same commands during Django installation.
To streamline the initialization of Django projects, I created an installation script for easy setup, which I’m sharing in this post. The script is a bash script designed to work seamlessly on Ubuntu 22 and should also be compatible with other versions. If you are using MacOs, you can simply remove the part that begins with '# Update package list and install dependencies' up until the next 'fi' line or comment out the block. While it is not strictly necessary to update your system before installing Django, it is generally a good practice to ensure your system is up to date.
What the script does:
1. It checks for system updates. If updates are available, it will attempt to update your system.
2. Creates a virtual environment for Django. If you’re new to Python development or the ecosystem, virtual environments are useful for isolating your project’s dependencies from other Python projects on your system. This ensures that any packages or libraries required by your Django project are installed and managed separately, avoiding conflicts and keeping your environment clean and organized.
3. Installs Django.
4. Starts the Django application, which you can access at http://127.0.0.1:8000 in your web browser.
