    Link fields

    Suppose our blog_post model has the following fields:

    • author: Single link referencing a user record;
    • related_posts: Multiple links referencing other blog_post records;

    In this case, blog_post.author will return the linked user record (or null, if the relation is empty), and blog_post.related will return an array of blog_post records.

    // dato.config.js
    module.exports = (dato, root, i18n) => {
    dato.blogPosts[0].author.fullName; // => "Mark Smith"
    dato.blogPosts[0].related.forEach(relatedPost => {
    relatedPost.title; // => "Another post!"
    })
    }

    Use method chains to navigate deeply across your records' relationships:

    // dato.config.js
    module.exports = (dato, root, i18n) => {
    dato.blogPosts[0].related[0].author.name // => "Tom Kepler"
    };

    Reverse lookups

    You can easily find all the blog post for a specific author with this Javascript one-liner:

    // dato.config.js
    module.exports = (dato, root, i18n) => {
    const peter = dato.find("1413");
    dato.blogPosts.filter(blogPost => blogPost.author.id === peter.id);
    }
