Fixing Django Pagination Issues: How to Show Links to Other Pages

When working with Django, pagination is a crucial feature, especially if you are displaying a significant amount of data. However, you may encounter problems where the pagination links are not showing up, leaving users unable to navigate between pages. This issue can be frustrating, especially when you have successfully implemented pagination in other projects. In this post, we will address the common issue of pagination links not appearing and provide a solution that ensures seamless navigation through your data.

Understanding the Problem

You might be learning Django from a book or online resources, and while you're making progress, you noticed that pagination works perfectly in some cases but fails in others. This is the case with a project you’re working on for your final year. Here’s a quick recap of the symptoms:

Each page displays the specified number of objects (3 in this case).

However, the links for navigating to other pages are completely absent.

This can be particularly troublesome, as pagination is vital for any user interface that involves long lists of items.

Your Existing Code

To better understand the issue, let’s review your existing implementation. You have a class-based view in your views.py file, which is correctly set up to paginate your objects:

Key Changes Explained

Pagination Check: Ensure you include {% if is_paginated %} to check whether your object list is actually paginated.

HTML List Structure: Use an unordered list (<ul>) to wrap your pagination links for better semantic markup.

Dynamic Page Links: The pagination now includes checks for first and last page links, along with the “Previous” and “Next” links.

Current Page Indication: It visually indicates the current page by disabling the link for it.

Conclusion

By following the solution provided, you should now have a working pagination feature in your Django application, with easy navigation links appearing as expected. Don’t forget to test your pagination thoroughly to ensure a smooth user experience.
