What is Django REST Framework (DRF)?
Câu trả lời
Django REST Framework is a powerful and flexible toolkit for building Web APIs with Django. It provides features like serialization, authentication, permissions, pagination and automatic documentation. DRF has become the de facto standard for building RESTful APIs in Python with Django, thanks to its browsable interface and reusable components.

What is the main role of a Serializer in DRF?
Câu trả lời
A Serializer in DRF converts complex objects like Django model instances into native Python data types that can then be easily rendered to JSON or XML. It also handles validation of incoming data and deserialization to transform JSON data into Python objects. Serializers are at the core of DRF and allow defining the data representation of the API.
3What is the difference between Serializer and ModelSerializer?
What is the difference between Serializer and ModelSerializer?
Câu trả lời
ModelSerializer is a subclass of Serializer that automatically generates fields based on the associated Django model. It automatically creates validators, implements default create() and update() methods, and significantly reduces boilerplate code. Serializer requires manually defining each field and create/update methods, offering more control but requiring more code.
