Modular content fields

Note This guide assumes you have a basic knowledge of how Modular content fields work in DatoCMS. If this is not the case, please read this introduction first.

Suppose a blog_post model has a modular content field called content, which in turn accepts the following building-blocks:

  • Model blog_post_text_block: made of a text field (multi-paragraph text);
  • Model blog_post_quote_block: made of a quote field (multi-paragraph text) and author field (single-line string);
  • Model blog_post_gallery_block: made of a gallery field (image gallery);

A modular content field works much like a multiple links field, as it returns an array of the inner records. In your dato.config.js file you can dump a modular content field inside the frontmatter of a post like this:

// dato.config.js

module.exports = (dato, root, i18n) => {

  // inside a "content/article" directory...
  root.directory("content/article", (articlesDir) => {

    // ...iterate over the "Blog post" records...
    dato.blogPosts.forEach((article) => {

      // ...and create a markdown file for each article!
      articlesDir.createPost(
        `${article.slug}.md`, "yaml", {
          frontmatter: { 
            title: article.title, 
            author: article.author.name,
            content: article.content.toMap()
          }
        }
      );
    });
  });
};
<article>
  <header>
    <h1>{{ .Title }}</h1>
    <p>{{ .Params.author }}</p>
  </header>

  {{ range .Params.content }}
    {{ if eq .itemType "blog_post_text_block" }}
      {{ .text }}
    {{ else if eq .itemType "blog_post_quote_block" }}
      <blockquote>
        {{ .quote }}
        <footer>
          <cite>{{ .author }}</cite>
        </footer>
      </blockquote>
    {{ else if eq .itemType "blog_post_gallery_block" }}
      <div class="gallery">
        {{ range .gallery }}
          <img src="{{ .url }}" alt="{{ .alt }}" title="{{ .title }}" />
        {{ end }}
      </div>
    {{ end }}
  {{ end }}
</article>
