What is the best way to create a sortable column that is based on a nested object within data.record?

I am utilizing jquery jtable to showcase some data in a table. I have been using the following code snippet for each field in the table to display the data and enable sorting:

sorting: true,
display: (data) => {
    return data.record.<whatever_value>;
}

This method has worked well for all fields except for one, where I need to sort based on a nested object within record. However, using the following code does not yield the desired result:

sorting: true,
display: (data) => {
    return data.record.<Nested_Object>.<Nested_value>;
}

I have been unable to pinpoint the issue. Any guidance on resolving this would be greatly appreciated. Thanks.

Answer №1

Unlike many other table plugins, jTable does not handle sorting directly. Instead, all sorting operations are delegated to the server side. When a listAction request is sent from jTable, it contains the sorting parameter jtSorting = "fieldName ASC/DESC";

Typically on the server side, this parameter is validated and then passed to the database in the ORDER clause. If you have special fields that require complex sorting logic, you will need to implement a compound ORDER clause to accommodate multiple subfields.
