Practice - 5 Tasks

1fill in blank

easy

Complete the code to asynchronously get all objects from the model.

Django

async def get_all_books():
    books = await Book.objects.[1]().aall()

💡 Hint

Common Mistakes

Using non-existent methods like 'all_async()' or 'fetch_all()'.

Forgetting to use 'await' before the ORM call.

In Django async ORM, you use 'all()' with await to get all objects asynchronously.

medium

Complete the code to asynchronously get a single object by its primary key.

Django

async def get_book(pk):
    book = await Book.objects.[1](pk=pk)
    return book

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using synchronous 'get()' without 'await'.

Using non-existent methods like 'get_async()'.

Django async ORM uses 'aget()' to asynchronously get a single object by filter.

3fill in blank

hard

Fix the error in the async save method call.

Django

async def save_book(book):
    await book.[1]()

Drag options to blanks, or click blank then click option'

Asave

Csave_async

Dasave

💡 Hint

Common Mistakes

Using synchronous 'save()' without 'await'.

Using incorrect method names like 'save_async()'.

Django async ORM uses 'asave()' to asynchronously save model instances.

4fill in blank

hard

Fill both blanks to asynchronously filter and count objects.

Django

async def count_books_by_author(author_name):
    count = await Book.objects.[1](author=author_name).[2]()
    return count

Drag options to blanks, or click blank then click option'

Afilter

Bcount

Cacount

Dafilter

💡 Hint

Common Mistakes

Using 'afilter()' which does not exist.

Using synchronous 'count()' without 'await'.

Use 'filter()' to filter queryset and 'acount()' to asynchronously count the results.

5fill in blank

hard

Fill all three blanks to asynchronously create, update, and save a model instance.

Django

async def create_and_update_book(title, new_title):
    book = await Book.objects.[1](title=title)
    book.title = [2]
    await book.[3]()

Drag options to blanks, or click blank then click option'

Aacreate

Bnew_title

Casave

Dcreate

Attempts:

3 left

💡 Hint

Common Mistakes

Using synchronous 'create()' instead of 'acreate()'.

Forgetting to await 'asave()'.

Assigning the wrong variable to book.title.

Use 'acreate()' to asynchronously create, assign new_title to book.title, then 'asave()' to save asynchronously.
