How to Fix 404 Page Not Found Error in Django for a Specific URL
Encountering a 404 Page Not Found error in Django can be frustrating, especially when it pertains to a specific URL. This error, represented by the HTTP status code 404, typically indicates that the requested URL is not mapped to any view in your Django application. In this guide, we will walk you through the common causes of this error and provide solutions on how to resolve it.
Common Causes of 404 Errors in Django
Incorrect URL Configuration
One of the most common reasons for a 404 error in Django is an incorrect URL configuration. This could be due to a typo in the URL pattern or a missing URL route in the urls.py file.
Missing View Function
Another reason could be that the view function associated with the URL is either not defined or is incorrectly referenced in the urls.py file.
Case Sensitivity and Trailing Slashes
Django URL patterns are case-sensitive, and trailing slashes are significant. A mismatch in case or a missing/extra trailing slash can result in a 404 error.
Solutions to Fix 404 Errors
Verify URL Patterns
Ensure that the URL patterns in your urls.py file are correct. For example, if you have a URL configuration for a guide, it should look something like this:

Check View Functions
Make sure that the view functions referenced in your urls.py file are correctly defined in your views.py file. For instance, the blog_home and blog_detail views should be defined as:

Case Sensitivity and Trailing Slashes
Double-check the case and trailing slashes in your URLs. For example, if the URL pattern is defined as path('blog/', views.blog_home), accessing /blog without the trailing slash will result in a 404 error. Use Django’s APPEND_SLASH setting to automatically append a trailing slash to URLs.
