Dato Config RB

I am trying to loop through a modular block on a page. I am trying to limit the data that goes into the collection but dato is giving me the kitchen sink. How can we limit the data??


inside a “_posts” directory…

directory “_feature-pages” do

…iterate over the “Blog post” records…

dato.feature_pages.each do |feature|

# ...and create a markdown file for each article!
create_post "#{feature.slug}.md" do
  frontmatter :yaml,
    title: feature.title,
	permalink: feature.permalink,
	layout: "feature-page",
	pl: "..#{feature.permalink}",
	h2: feature.h2,
	summary: feature.content,
	order: feature.order,
	background: feature.background,
	image: feature.image.url(w: 800, fm: :png),
	thumb: feature.thumb.url(w: 200, fm: :png),
	topimage: feature.top_image,
	seotitle: feature.seo.title,
	seodesc: feature.seo.description,

	related: feature.related_features,
	item: feature.feature_items do |items|



I need to get the data out like this

hello @derrick, I’m pasting the answer publicly here as well as it might benefit someone else.

In your case the SEO field is optional, and so it might be empty. You need to check for that in your script to prevent hitting a null object.

In particular you can do something like this:

        seotitle: feature.seo ? feature.seo.title : '',
        seodesc: feature.seo ? feature.seo.description : '',

Or alternatively you can make the SEO attribute required and leave your script as it is. That depends on how you plan to do things.

didnt work

		seotitle: feature.seo ? feature.seo.title : '',
		seodesc: feature.seo ? feature.seo.description : '',

this is what fixed it
