Question

SilverStripe 2.4.7

Hi

I’m trying to put together a template to structure my JSON. My classes have relationships as follows.

A store can have many offers and many news articles. Offers and news articles can belong to many stores.

My template looks like this

{
"StoresHolder" : [
<% control Children %>
{
    "ID" : "$ID",
    "Name" : "$Name",
    "Address1" : "$Address1",
    "Address2" : "$Address2",
    "County" : "$County",
        "News"  : [
            <% control News %>
            {
            "ID" : "$ID",
            "Title" : "$Title",
            "DatePublished" : "$DatePublished",
            "ExpiryDate" : "$ExpiryDate",
            "Body" : "$Body",
            "URL" : "$URL",
            "Photo" : "$Photo.Filename"
            }<% if Middle %>,<% end_if %>
            <% end_control %>
        ],
        "Offers" : [
            <% control Offers %>
            {
            "ID" : "$ID",
            "Title" : "$Title",
            "Description" : "$Description",
            "Weight" : "$Weight",
            "Price" : "$Price",
            "Savings" : "$Savings",
            "Expires" : "$Expires",
            "Photo" : "$Photo.Filename"
            }<% if Middle %>,<% end_if %>
            <% end_control %>
        ]
}<% if Last %> <% else %>,<% end_if %>
<% end_control %>
]
}

I got it working to the point that it displays only one of the offers and news articles but I can’t get any further. Any advice is hugely appreciated.

This doesn’t look right – in the sense of: Have you taken a look at something like this:

$data = DataObject::get(...); 
$formatter = new JSONDataFormatter(); 
return $formatter->convertDataObjectSet($data);

Combined with the proper handling of DataObjectSets, this should be a better approach.
Unless you have very specific reasons for requiring something different – then please state them
