Teaching Item: Introduction to Django URLs

Class: Bachelor

Objective:

Students will learn the basics of URL routing in Django, including defining URL patterns, mapping URLs to views, and organizing URL patterns in a Django project.

Materials Needed:

• Python installed (preferably Python 3.x)
• Text editor or integrated development environment (IDE) such as VSCode, PyCharm, or Sublime Text
• Django framework installed (pip install django)
• Projector

1. Introduction to URL Routing (15 mins)

• Overview of URL routing:
  • URL routing maps URLs to views in a Django application.
  • URLs are defined in the project's urls.py modules.
• Discuss the importance of URL routing in web applications and navigation.

2. Creating URL Patterns (20 mins)

• Defining URL patterns:
  • Create regular expressions (regex) patterns to match URLs.
  • Define URL patterns using the urlpatterns list.
  • Use the path() function for simple URL patterns.
• Example: Define a simple URL pattern to map a URL to a view function.

3. Mapping URLs to Views (20 mins)

• Connecting URLs to views:
  • Import view functions or classes into the urls.py module.
  • Use the path() function to map URLs to view functions or classes.
• Example: Map a URL pattern to a view function defined in a Django app.

4. URL Namespaces and Naming URL Patterns (20 mins)

• URL namespaces:
  • Organize URL patterns using namespaces for better organization.
  • Avoid naming conflicts between different apps.
• Naming URL patterns:
  • Assign unique names to URL patterns using the name argument.
  • Use named URLs in templates for dynamic URL generation.
• Example: Define URL namespaces and name URL patterns in a Django project.

5. Including URL Patterns (20 mins)

• Including URLs from apps:
  • Organize URL patterns by including URLs from individual apps.
  • Use the include() function to include URLs from other modules.
• Example: Include URLs from multiple apps into the project's main urls.py module.

6. Path Converters and Capturing URL Parameters (20 mins)

• Using path converters:
  • Capture dynamic segments of URLs using path converters.
  • Extract parameters from URLs and pass them to view functions.
• Example: Define URL patterns with path converters to capture dynamic segments.

7. Exercise: Define and Map URLs (20 mins)

• Provide a hands-on exercise where students define URL patterns and map them to views in a Django project.
• Task:
  • Define multiple URL patterns for different views in a Django app.
  • Map the URL patterns to corresponding view functions or classes.
  • Test the URLs by accessing them in a web browser and verify the routing.

8. Conclusion (10 mins)

• Recap the key points covered in the lesson:
  • URL routing maps URLs to views in a Django application.
  • URL patterns are defined using regular expressions and the path() function.
  • URL namespaces and naming URL patterns improve organization and maintainability.
  • Including URLs from multiple apps allows for modularization and reusability.
  • Path converters capture dynamic segments of URLs for flexible routing.
• Encourage students to practice defining and mapping URLs in their Django projects and explore advanced routing techniques.
