Batch create endpoint design in Rest API - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the HTTP method for a batch create endpoint.

Rest API

app.[1]('/items/batch', create_items_batch)

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

ADELETE

BPUT

CPOST

DGET

💡 Hint

Common Mistakes

Using GET instead of POST for creating resources.

Using DELETE or PUT which are for other operations.

The batch create endpoint should use the POST method because it is used to create new resources.

medium

Complete the code to accept a list of items in the request body for batch creation.

Rest API

def create_items_batch():
    items = request.[1]

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

Aargs

Bjson

Cform

Dheaders

💡 Hint

Common Mistakes

Using request.args which reads query parameters instead of body.

Using request.form which is for form data, not JSON.

request.json is used to get JSON data from the request body, which is typical for batch create endpoints.

3fill in blank

hard

Fix the error in the batch create function to correctly iterate over the items list.

Rest API

def create_items_batch():
    items = request.json
    for [1] in items:
        save_item(item)
    return {'status': 'success'}

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

💡 Hint

Common Mistakes

Using the list variable name as the loop variable.

Using an undefined variable inside the loop.

The loop variable should be a single item, here named 'item', to iterate over the list 'items'.

4fill in blank

hard

Fill both blanks to validate each item has a 'name' key and return error if missing.

Rest API

def create_items_batch():
    items = request.json
    for item in items:
        if [1] not in item:
            return [2]
    return {'status': 'success'}

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

A'name'

B{'error': 'Missing name'}

C'id'

D{'error': 'Invalid data'}

Attempts:

3 left

💡 Hint

Common Mistakes

Checking wrong keys like 'id' instead of 'name'.

Returning a generic error message instead of specific.

We check if 'name' key is missing in each item and return a specific error message if so.

5fill in blank

hard

Fill all three blanks to create a batch endpoint that saves items and returns count of created items.

Rest API

def create_items_batch():
    items = request.[1]
    count = 0
    for [2] in items:
        save_item([3])
        count += 1
    return {'created': count}

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

Ajson

Bitem

Dargs

Attempts:

3 left

💡 Hint

Common Mistakes

Using request.args instead of request.json.

Using different variable names inconsistently.

The function reads JSON data, iterates over each item, saves it, and counts how many were created.
