## URLs

__Step 1__: Create the URLs file in App folder.

__Step 2__: Attach the `urls.py` file from the application folder to the `urls.py` file in the project folder.

## What is Router ?

In DRF, you define routes for your API using the `router` class. This class provides a quick and convenient way to organize routes for your API. Typically, the `DefaultRouter` is used, which automatically generates routes for standard CRUD operations based on your views.

Here's an example of how you can use `DefaultRouter`:



```python
from rest_framework import routers
from .views import ProductViewSet

router = routers.DefaultRouter()
router.register(r'products', ProductViewSet)

urlpatterns = router.urls
```


In this example, we're registering the `ProductViewSet` view for the `/products` route. DRF automatically generates routes for standard CRUD operations on this URL.

So, with the help of routers in DRF, you can easily organize routes for your API and automatically generate routes for your web service based on your views.  

What is the purpose of using routers in Django Rest Framework (DRF)?

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.
