Resolving the Django AJAX Call URL Not Found Issue

Using AJAX with Django can be incredibly powerful for creating dynamic web applications, but sometimes you may run into issues that can halt your progress. One common problem developers face is the "URL not found" error when making AJAX calls to Django views. This guide aims to guide you through troubleshooting this issue effectively.

Understanding the Problem

In this case, the developer wanted to send data from an AJAX call to a Django view but encountered a 404 error when attempting to access the URL constructed for the AJAX request. The URL in the error message was as follows:

The AJAX call itself appears to be functioning since the known_words variable was incrementing correctly. However, there were issues with the URL format expected by the Django application.

Common Causes of the Issue

When faced with a 404 error during AJAX calls in Django, consider the following common causes:

Incorrect URL Path Configuration: Ensure that the URL patterns are set up correctly in your application.

Missing URL Arguments: The AJAX request URL must align with the parameters defined in your Django views and URLs.

Improper HTTP Method: Django views often handle different methods (GET, POST). If you're not aligning your requests correctly, it can lead to errors.

Step-by-Step Solution

Step 1: Revise Your Django View

Initially, the Django view for handling the AJAX call was as follows:
