Search and Ordering in Django

📖 Scenario: You are building a simple Django app to display a list of books. Users want to search for books by title and order the results by price.

🎯 Goal: Create a Django view that filters books by a search term in the title and orders the results by price.

📋 What You'll Learn

Create a list of books as Django model instances

Add a search term variable to filter books by title

Use Django QuerySet filtering and ordering

Return the filtered and ordered books in the view

💡 Why This Matters

🌍 Real World

Filtering and ordering data is common in web apps to help users find and sort items like products or articles.

💼 Career

Understanding how to filter and order data is essential for backend and full-stack developers working with databases and APIs.

1

Create the initial list of books

Create a list called books with these dictionaries exactly: {'title': 'Django Basics', 'price': 30}, {'title': 'Advanced Django', 'price': 45}, {'title': 'Python for Beginners', 'price': 25}, {'title': 'Django and REST', 'price': 40}

Django

# Create the list of books with title and price
# Your code here

Need a hint?

Use a list of dictionaries with keys 'title' and 'price'.

2

Add a search term variable

Create a variable called search_term and set it to the string 'Django'

Django

books = [
    {'title': 'Django Basics', 'price': 30},
    {'title': 'Advanced Django', 'price': 45},
    {'title': 'Python for Beginners', 'price': 25},
    {'title': 'Django and REST', 'price': 40}
]
# Create a variable search_term with value 'Django'
# Your code here

Need a hint?

Set search_term to the exact string 'Django'.

3

Filter books by search term in title

Create a list called filtered_books that includes only books from books where search_term is in the book's title (case sensitive). Use a list comprehension.

Django

books = [
    {'title': 'Django Basics', 'price': 30},
    {'title': 'Advanced Django', 'price': 45},
    {'title': 'Python for Beginners', 'price': 25},
    {'title': 'Django and REST', 'price': 40}
]
search_term = 'Django'
# Filter books by search_term in title
# Your code here

Need a hint?

Use a list comprehension with if search_term in book['title'].

4

Order filtered books by price

Create a list called ordered_books by sorting filtered_books by the price key in ascending order using the sorted() function and a lambda function.

Django

books = [
    {'title': 'Django Basics', 'price': 30},
    {'title': 'Advanced Django', 'price': 45},
    {'title': 'Python for Beginners', 'price': 25},
    {'title': 'Django and REST', 'price': 40}
]
search_term = 'Django'
filtered_books = [book for book in books if search_term in book['title']]
# Sort filtered_books by price ascending
# Your code here

Need a hint?

Use sorted(filtered_books, key=lambda book: book['price']) to order by price.
