Django Tutorial #2 - Setup & Installation

Introduction

This tutorial will guide you through the setup and installation of Django, a powerful web framework for building web applications using Python. By the end of this guide, you'll have a Django project up and running, ready for development.

Step 1: Install Python

Before installing Django, ensure you have Python installed on your system. Follow these steps:

1. Check Python Installation

   • Open a terminal or command prompt.
   • Type python --version or python3 --version to check if Python is installed.

2. Download Python

   • If Python is not installed, download it from the official website: python.org.
   • Follow the installation instructions for your operating system (Windows, macOS, or Linux).

3. Add Python to PATH

   • During installation on Windows, ensure you check the box to add Python to your PATH.

Step 2: Install Django

Once Python is installed, you can proceed with installing Django.

1. Open Terminal or Command Prompt

   • Ensure you have access to a terminal or command prompt.

2. Install Django with pip

   • Run the following command:

     pip install django
     

   • This command will download and install the latest version of Django from the Python Package Index (PyPI).

3. Verify Django Installation

   • After installation, check the version of Django by running:

     python -m django --version
     

   • Ensure that it displays the installed version without errors.

Step 3: Create a New Django Project

Now that Django is installed, you can create a new project.

1. Navigate to Your Development Directory

   • Use the cd command to navigate to the folder where you want your project:

     cd path/to/your/development/directory
     

2. Start a New Django Project

   • Run the following command to create a new project named "myproject":

     django-admin startproject myproject
     

3. Navigate into Your Project

   • Change into the project directory:

     cd myproject
     

Step 4: Run the Development Server

To see your Django project in action, start the development server.

1. Run the Server

   • Execute the command:

     python manage.py runserver
     

2. Access the Development Server

   • Open a web browser and go to http://127.0.0.1:8000/.
   • You should see the Django welcome page, indicating that your project is set up correctly.

Step 5: Explore Project Structure

Familiarize yourself with the structure of your new Django project.

1. Key Files and Directories

   • manage.py: A command-line utility for interacting with your project.
   • settings.py: Configuration settings for your Django project.
   • urls.py: URL routing for your application.
   • wsgi.py: Entry point for WSGI-compatible web servers to serve your project.

2. Understanding the Structure

   • Each of these files plays a crucial role in the functionality of your Django application.

Conclusion

You have successfully set up and installed Django, created a new project, and run the development server. From here, you can start building your web application by adding models, views, and templates.
