Understanding the Pagination Problem in Odoo 16 Custom Websites

When working with Odoo 16 and creating custom websites, developers often encounter issues related to pagination, particularly when trying to display search results. A common predicament arises when the pagination system inadvertently pulls all records from the database instead of just showing the specified results for each page. This can lead to performance issues and impede user experience.

In this guide, we'll dive into the specific problem of pagination you've described, with a focus on understanding why you might be seeing all data being retrieved and how to fix it effectively.

The Problem

You have set up pagination in your search results but noticed that when you navigate through the pages, all data from the database is being pulled rather than just the data relevant to the current page. This issue could potentially stem from an incorrectly implemented search count mechanism.

Example Scenario

When you initiate a search request, everything seems to be working properly for the first query set.

However, when navigating through pagination, the total count of records returned includes every entry in the database, not just the filtered results based on your search query.

Breaking Down the Solution

1. Understanding the Search Count

In order to effectively implement pagination, you need to ensure that the count of records being paginated reflects only the relevant results. This involves modifying your existing code to consider the search criteria when determining the total count.

2. Updating Your Code

Let’s modify the code you’ve provided to ensure that the count of records reflects your search criteria:

Revised Code Snippet

We recommend changing your implementation by including the appropriate search conditions directly in the search_count method.

3. Explanation of the Changes

The line total = len(customer_obj) effectively calculates the number of records in the customer_obj that you've already filtered using the search criteria.

Instead of using search_count([]) which pulls all records, employing the length of the filtered object provides an accurate total which corresponds to the displayed results.

The url_args parameter allows you to retain the search query as you paginate, improving the overall user experience by maintaining context.

Conclusion

Correctly implementing pagination in Odoo 16 custom websites can significantly enhance performance and user experience. By ensuring the total count of records reflects your search conditions, you can avoid retrieving unnecessary data that clutters your pages and slows down your application.

If you find yourself facing similar issues, refer back to these guidelines and adapt your search logic accordingly. Happy coding!
