What are Django URL patterns and how do I use them?

Django URL patterns are used to route incoming web requests to the appropriate view functions. They are defined in the urls.py file.

Can you show me an example of how to define a URL pattern?

Sure! Here's a simple example:

from django.urls import path
from . import views

urlpatterns = [
    path('home/', views.home, name='home'),
]

This maps the URL '/home/' to the home view.

What if I want to include parameters in my URL?

You can include parameters by using angle brackets. For example:

path('article/<int:id>/', views.article_detail, name='article_detail')

This captures an integer parameter id from the URL.

How do I handle different HTTP methods in my views?

You can handle different HTTP methods by checking request.method in your view function. For example:

def article_detail(request, id):
    if request.method == 'POST':
        # handle POST request
    else:
        # handle GET request
