Nested object data (arrays) with dynamic length

Exer

Hello guys,
This is my problem:

{
    "aaData": [
        {
            "Days": [
                {
                    "FromDay": "2015-02-07",
                    "ToDay": "2015-02-09"
                },
                {
                    "FromDay": "2015-02-10",
                    "ToDay": "2015-02-12"
                }
            ]
        },
        {
            "Days": [
                {
                    "FromDay": "2015-02-05",
                    "ToDay": "2015-02-06"
                }
            ]
        }
    ]
}

This is my JSON it has nested Array of object called "Days" but this array is dynamic ( it can have different number of objects in it ).
So my question is how can i draw this in my DataTable, what i did for now is :

"columns": [
                { "data": "Days.0.FromDay" },
                { "data": "Days.0.ToDay" },
            ]

I saw it here http://datatables.net/examples/ajax/objects_subarrays.html, It works, but only for first object in array. I would appreciate if anyone could tell me how to loop through each and show all array objects in same column... Thanks in advance

It depends on what you want the outcome to be. If you want every Days object to be a separate row you would need to transfer the array as each entry in aaData is a row. There is no way around that.

If you want to show the Days array in a concatenated form you could use data: "Days[, ].FormDay" or if you want some other formatting use data: "Days" and then use columns.render as a function so you can control the output.

Hey allan, first of all thanks for a quick reply,

data: "Days[, ].FormDay"

was what i needed, but its always good to know there's way to control my output.
