Supporting HATEOAS

blacar

Im new to datatables and wants to integrate with a server using spring-data-rest JSON HAL format
(https://tools.ietf.org/html/draft-kelly-json-hal-06)

Is this scenario supported in some way?

Can i custom parse the JSON response?

Thanks

Can i custom parse the JSON response?

Use, use columns.data to tell DataTables what object property to read for each column.

Perhaps if you could show an example of your JSON I might be able to provide a little more help.

Thanks Allan,

I need to consume HAL formatted responses like you can see below. If you are not familiar with HAL format it has three sections: 1st links that we can overpass, 2nd instant values and 3rd _embedded entities that holds also values we want to see.

My problem it's with _embedded values ... i have no clear how to do that mapping

The example is:

{
    "_links": {
        "self": { "href": "/orders" },
        "curies": [{ "name": "ea", "href": "http://example.com/docs/rels/{rel}", "templated": true }],
        "next": { "href": "/orders?page=2" },
        "ea:find": {
            "href": "/orders{?id}",
            "templated": true
        },
        "ea:admin": [{
            "href": "/admins/2",
            "title": "Fred"
        }, {
            "href": "/admins/5",
            "title": "Kate"
        }]
    },
    "currentlyProcessing": 14,
    "shippedToday": 20,
    "_embedded": {
        "ea:order": [{
            "_links": {
                "self": { "href": "/orders/123" },
                "ea:basket": { "href": "/baskets/98712" },
                "ea:customer": { "href": "/customers/7809" }
            },
            "total": 30.00,
            "currency": "USD",
            "status": "shipped"
        }, {
            "_links": {
                "self": { "href": "/orders/124" },
                "ea:basket": { "href": "/baskets/97213" },
                "ea:customer": { "href": "/customers/12369" }
            },
            "total": 20.00,
            "currency": "USD",
            "status": "processing"
        }]
    }
}

Not at all - thanks for your introduction to it.

What do you want to get out of it. Is each ea:order a row in the table? If so then use ajax.dataSrc and set it to be _embedded.ea:order.
