I'm struggling to order items returned via the Kontent.ai delivery rest API using a field on the linked item of that piece of content.

My content model is as follows:

  • Web Page - contains generic information about a given web page e.g. metadata, url slug etc.
  • Page Template - contains the page data, posted date, content etc.

Each Web Page must have a Page Template as a linked item, and I ideally want to order all web pages on the linked page template posted date on list pages for example. But I can't seem to find anywhere in the docs to suggest this is possible.

Has anyone had any success with doing this?

Here is what my current orderByDescending call looks like:

orderByDescending("elements.page_template.linkedItems[0].elements.publication_date")

But this gives me an error.

  • As @danielp suggests in his answer, this isn't something that can be done. In this kind of scenario, you also need to consider that there will be a time when the `Web Page` does not have a `Page Template` set. The restrictions in place when building the model will only prevent you from publishing the content item, but while editing and in preview the `page_template` element allows for an empty collection. – mnield May 15 '23 at 22:03

Unfortunately, It's not possible to order or filter based on values nested in linked items at the API level and by extension SDKs as the filtering methods are just abstractions of the API filtering operations. This has to do with the structure of the API response:

{
"items": [],
"modular_content": {},
"pagination": {}
}

In your case, the resulting items array contains the items of Web page type, which merely hold a codename reference to their respective Template items. All the actual linked items are stored in the modular_content array, which is unordered.

The only way to achieve this is to retrieve all required items from API and subsequently perform the ordering in your code.
