Customizing Your Symfony EasyAdminBundle Index Listings

When working with Symfony’s EasyAdminBundle, you may encounter situations where you need to tailor your data display to meet specific requirements. A common case arises when you want to filter out deleted users from an index listing. This guide will guide you through the process of overriding the createIndexQueryBuilder() method effectively, ensuring that you display only the active users in your application.

Understanding the Challenge

In your user entity, you typically have a field called isDeleted that indicates whether a user has been deleted (set to true) or is active (set to false). The default behavior of EasyAdminBundle might not accommodate your need to display only active users. Instead of modifying the entire index() method, it's more efficient to override the createIndexQueryBuilder() method, which generates the query builder responsible for fetching the results displayed in your index.

The Default createIndexQueryBuilder() Method

Here's what the original method looks like:

This method simply retrieves the default query builder without any filters applied.

Customizing the Query Builder

To implement filtering out deleted users, you need to add a condition to the query we receive in the createIndexQueryBuilder() method. Below are the steps to effectively override this method:

Step 1: Call the Parent Method

Begin your method by calling the parent method, which prepares the default query builder:

Step 2: Modify the Query Builder

Next, you need to properly add the condition to filter users whose isDeleted field is set to false (which you can represent as 0 in SQL). Here's how to do it correctly:

Key Adjustments in Your Code

Make sure to incorporate the following changes:

Use entity.isDeleted = 0 in your where clause. This refers to the isDeleted field in the context of the entity being queried.

Return the customized query builder at the end of the method.

Conclusion

By following these steps, you can effectively customize the index listings in Symfony EasyAdminBundle to exclude deleted users from your views. The power of EasyAdmin lies in its flexibility, allowing you to tailor the interface to suit your application’s needs without unnecessary complexity.

This approach not only simplifies your code but also enhances the user experience by presenting relevant data. Happy coding!
