__Step 1__: Create the `serializers.py` file in app folder.

__Step 2__: Create a serializer.

In DRF, when you create a serializer for a model, you use the `Meta` class to provide additional information on how the serializer should work.



```python
from rest_framework import serializers
from .models import Product


class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = '__all__'
```

- `model = Product`: This line tells the serializer to use the `Product` model for serialization. It means the serializer will work with objects of type `Product`.

- `fields = '__all__'`: This instructs the serializer to include all fields of the `Product` model in the serialization. If you wanted to specify particular fields, you could list them in an array instead of using `'__all__'` (like the example below).
```python
fields = ['name', 'description', 'price']
```

The entire `Meta` class defines which model to use and which fields of that model to include in the serialization. This allows the Django REST framework to automatically generate a serializer for the model with minimal effort on your part.

The Django REST Framework course opens the gateway to the world of web interface development, where you'll learn to create connections between servers and clients through APIs. As you delve into the technical details, you'll master how to transform complex data structures into network-friendly formats and vice versa. You'll understand how to efficiently handle user requests and return responses in a format that seamlessly integrates into web applications. 

We begin by understanding the fundamental concepts of RESTful API architecture, comparing Django to Django Rest Framework (DRF), and exploring JSON formatting. We'll also discuss the latest trends in web development and guide you through the installation and project setup process.

Serialization is a crucial aspect of building APIs. Here, we'll dive deep into serialization, exploring its importance, discussing various models, and understanding serializers in Django Rest Framework. Additionally, we'll cover built-in serializers for efficiency.

Next, we'll explore views and routers in DRF. We'll cover class-based views, their significance, and the built-in views provided by Django Rest Framework. Routers play a vital role in API routing, and we'll provide a comprehensive overview of how to utilize them effectively with DRF's API router.

Understanding HTTP request methods is essential for building robust APIs. We'll cover GET, POST, PUT, and DELETE methods, along with their practical applications. Additionally, we'll discuss HTTP response status codes and their significance in API development.
