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 models as building-blocks:
blog_post_text_block: made of a text field (multi-paragraph text);blog_post_quote_block: made of a quote field (multi-paragraph text) and author field (single-line string);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 the array of inner records. In your Middleman templates, to present a modular-content field, you can do something like this:
<article><header><h1><%= blog_post.title %></h1><p><%= blog_post.author.name %></p></header><% blog_post.content.each do |record| %><% if record.item_type.api_key == "blog_post_text_block" %><div><%= record.text %></div><% elsif record.item_type.api_key == "blog_post_quote_block" %><blockquote><%= record.quote %><footer><cite><%= record.author %></cite></footer></blockquote><% elsif record.item_type.api_key == "blog_post_gallery_block" %><div class="gallery"><%= record.gallery.each do |image| %><img src="<%= image.url() %>" alt="<%= image.alt %>" title="<%= image.title %>" /><% end %></div><% end %><% end %></article>
