How do I handle URL parameters in Django?

In Django, you can handle URL parameters by defining them in your URL patterns using angle brackets. For example, in your urls.py, you can define a path like path('article/<int:id>/', views.article_detail) to capture an integer parameter named id.

Can you show me an example of how to access that parameter in a view?

Sure! In your view function, you can access the parameter like this:

from django.shortcuts import render

def article_detail(request, id):
    # Now you can use the 'id' parameter to fetch the article
    article = get_object_or_404(Article, pk=id)
    return render(request, 'article_detail.html', {'article': article})

What if I want to pass multiple parameters?

You can define multiple parameters in your URL pattern. For example:

path('article/<int:id>/comment/<str:comment_id>/', views.comment_detail)

In your view, you can access both id and comment_id.

Is there a way to make parameters optional?

Yes, you can make parameters optional by using a default value in your view function and defining a URL pattern with a question mark. For example:

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