Teaching lesson plan 26 Subject: Python programming

Date: 13 Feb 2024

Time: 60 minutes

Period: 3rd

Teaching Item: Introduction to Django Views

Class: Bachelor

Objective:

Students will learn the fundamentals of Django views, including defining views, handling HTTP requests, rendering templates, and passing context data to templates

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 Django Views (15 mins)

• Overview of Django views:
  • Views are Python functions or classes that handle HTTP requests and return HTTP responses.
  • Views encapsulate the logic for processing user requests and generating responses.
• Discuss the role of views in the Django MTV (Model-Template-View) architecture.

2. Creating Views (20 mins)

• Creating a Django app for views: python manage.py startapp myapp
• Defining view functions:
  • Define view functions to handle specific URL patterns.
  • Views accept HTTP request objects and return HTTP response objects.
• Example: Creating a simple view function to render a basic HTML page.

3. Routing URLs to Views (20 mins)

• Configuring URL patterns:
  • Define URL patterns in the app's urls.py module.
  • Map URL patterns to corresponding view functions.
• Include app-specific URL patterns in the project's main urls.py file.

4. Handling HTTP Requests and Responses (25 mins)

• Accessing request data:
  • Extracting data from HTTP request objects (e.g., GET and POST parameters).
  • Processing form data submitted via POST requests.
• Generating responses:
  • Rendering HTML templates using the render() function.
  • Returning JSON responses using the JsonResponse class.

5. Passing Data to Templates (20 mins)

• Passing context data to templates:
  • Define a context dictionary with data to be passed to the template.
  • Render the template with context data using the render() function.
  • Access data in the template using template variables.
• Example: Passing dynamic data from a view to a template.

6. Class-Based Views (20 mins)

• Introduction to class-based views:
  • Class-based views provide a more structured way to organize view logic.
  • Advantages of class-based views over function-based views.
• Common class-based views:
  • View: Base class for all class-based views.
  • TemplateView: Render a template.
  • ListView and DetailView: Display lists and details of objects.

7. Exercise: Create and Render Views (20 mins)

• Provide a hands-on exercise where students create Django views and render templates.
• Task:
  • Define multiple view functions to handle different URL patterns.
  • Render HTML templates using the render() function and pass context data.
  • Test the views by accessing different URLs in a web browser.

8. Conclusion (10 mins)

• Recap the key points covered in the lesson:
  • Django views handle HTTP requests and generate HTTP responses.
  • Views can be defined as functions or classes and are responsible for processing user requests.
  • URL patterns route incoming requests to the appropriate view functions.
  • Views can pass context data to templates for dynamic rendering.
  • Class-based views provide a more object-oriented approach to organizing view logic.
• Encourage students to practice creating and testing views in their Django projects.
