In my front matter I specify the related content files like this:
related = ["article 1", "article 2"]
I then generate a list with the related articles like this:
{{ $sectionArticles := where $.Site.RegularPages "Section" .Page.Section }}
{{ $relatedContent := where $sectionArticles "Title" "in" .Page.Params.related }}
But how can I generate a list of page titles that were included in the related
front matter, but that were not found in the .Site.RegularPages
array?
I looked at the functions doc, but intersect
returns an array with common elements (I’m looking for the non-matching), and I couldn’t get not in
to work (understandably so):
{{ $notFound := where .Page.Params.related "not in" $sectionArticles }}
error calling where: not in is neither a struct field, a method nor a map element of type string.
This also doesn’t work:
{{ $relatedContent := where $sectionArticles "Title" "not in" .Page.Params.related }}
Because it returns a list of all pages, whereas I’m only interested in the page titles that occurred in related
but weren’t found in .Site.RegularPages
.
Any ideas or suggestions? Thanks!
