Query related document on single document query

[feicht.marco (Marco Feicht)]

Hi,

currently I'm testing to fetch data on the server side with Next.JS and the following code:

export async function getServerSideProps({ query }) {
  const client = Client();

  const report = await client.getByUID("report", query.slug, { lang: "de-de" });

  return {
    props: {
      report
    }
  };
}

In the content model I've also integrated a repeater field with a content relationship. Now I want to query also the content of the documents from the content relationship field.

How can I do this?

Hey Marco!

Thanks for posting this question. There are a few ways to do this:

• You could you GraphQuery (which has a similar syntax to GraphQL) to fetch content from linked documents
• You could add a forEach loop after your first query to iterate over the repeater field and query each document
• Or — and this is what I recommend — you can add a fetchLinks option to your query to fetch the content that you need

If you'd like to use fetchLinks, there are some instructions here:

Query content relationship inside slice in repeatable zone

Hey @rizqinizamil, Welcome to the Prismic community, and thanks for posting this question! To fetch content relationships, you can use the fetchLinks option: To use fetchLinks, add an options object to your query, with a fetchLinks key. For the fetchLinks key, set the value to [custom-type-of-linked-document].[field-on-linked-document]. When you include the fetchLinks option, the API will fetch the field on every linked custom type in your document, incl…

Let me know if you have any questions about fetchLinks. And, otherwise, If you'd like more info on GraphQuery or using a foreach loop, let me know

Best,
Sam

Hi @samlittlefair,

I already tried to use the fetchLinks option, but did it wrong. Now it's working.

Thanks for your help!
