Django - REST Framework Basics

Given this serializer and data:

class BookSerializer(serializers.Serializer):
    title = serializers.CharField()
    pages = serializers.IntegerField()

serializer = BookSerializer(data={'title': 'Django Guide', 'pages': 250})
serializer.is_valid()

What will serializer.is_valid() return?

AFalse

BRaises a TypeError

CTrue

DReturns None

Step-by-Step Solution

Solution:

Step 1: Understand serializer validation
Calling is_valid() checks if provided data matches serializer fields and types.
Step 2: Check data correctness
Data has 'title' as string and 'pages' as integer, matching field types, so validation passes.
Final Answer:
True -> Option C
Quick Check:
Valid data = is_valid() returns True [OK]

Quick Trick: is_valid() returns True if data matches serializer fields [OK]

Common Mistakes:

MISTAKES

Assuming is_valid() returns data instead of boolean
