Mastering Laravel YajraBox: Sorting Relationships in DataTables

When building applications with Laravel, one often encounters the need to display data from related tables. This is particularly common when using the popular DataTable library, YajraBox. However, some developers face a challenge when it comes to sorting relationship columns within these tables. If you have found yourself in a similar predicament, you are not alone.

In this guide, we will explore a specific problem regarding relationship sorting in YajraBox and provide a clear solution. Let's dive into the issue and uncover how you can resolve it effectively.

Understanding the Problem

In a Laravel project utilizing DataTables with YajraBox, a developer encountered issues with sorting data from relational models. Specifically, they noticed that when attempting to sort by a related column (from the provinsi model), the DataTable was unable to recognize the column due to a missing join in the query.

The Specific Issue

The developer provided the following points of contention:

When accessing the $id in the action column, it returned provinsi.id instead of the expected kabupaten.id.

Attempts to use the with method allowed $id to return the correct value, but resulted in the inability to sort the provinsi column, with an error indicating that the column was not found.

The Solution

In order to resolve this issue, the recommended approach is to use SQL JOINs instead of relying purely on Eloquent relationships. By joining the provinsi table directly within your query, you ensure that the necessary fields are available for sorting. Here’s how to implement this solution step-by-step.

Step 1: Updating Your Query Method

You will need to modify the query() method in your KabupatenDataTable class to include a JOIN statement. Here’s a revised version of the method:

In this code:

We’ve switched from with() to leftJoin() to directly join the provinsi table with kabupaten.

We then select all columns from the kabupaten table, along with the provinsi column, giving it an alias of provinsi_provinsi.

Step 2: Adding the Column in DataTable

To ensure that your column is accessible for sorting and display in the DataTable, you need to define it with the proper name and title.

Add the following line to your getColumns() method:

Conclusion

By implementing the above changes, you will resolve the sorting issue in your YajraBox DataTable. This approach effectively allows columns from related tables to be utilized within your DataTables, giving your users a better experience when interacting with data.
