Analyzing Django View and URL Mapping

# urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('user/<int:user_id>/profile/', views.user_profile, name='user_profile'),
    path('user/<int:user_id>/settings/', views.user_settings, name='user_settings'),
]

# views.py
from django.shortcuts import render

def user_profile(request, user_id):
    return render(request, 'profile.html', {'user_id': user_id})

def user_settings(request, user_id):
    return render(request, 'settings.html', {'user_id': user_id})

  1. The URL pattern `<int:user_id>` extracts the integer from the URL and passes it as a keyword argument named 'user_id' to the view function.

  2. The <int:user_id> converter is optional; if omitted, Django automatically detects the parameter type from the view function signature.

  3. URL converters like <int:user_id> only work with function-based views, not class-based views.

  4. The user_id parameter must be manually extracted from request.GET in the view function; the URL converter only validates the format.

Show answer & explanation

Correct answer

The URL pattern `<int:user_id>` extracts the integer from the URL and passes it as a keyword argument named 'user_id' to the view function.

Explanation

URL path converters like <int:user_id> automatically extract and convert the URL segment to the specified type, passing it as a keyword argument to the view function.
