HUGO: error calling where: can't evaluate the array by no match argument or more than or equal to two arguments

Question

I am trying to create a ul list of the sections of my hugo site and their child pages that have a specific param.

I basically want a multi-level ul menu at the side like so:

• Intro
  • Page 1
  • Page 2
• Section
  • page 3
  • page 4

Here is the Hugo Code I have so far:

<ul class="section-one-and-two-pages">
{{ range .Site.Pages }}
    {{ range where ( where .Section  "intro" ) or ".Params.type" "==" "article" }}
   <li>{{.Permalink}}{{.Title}}</li>
    {{end}}
{{ end }}
</ul>

At the top of my pages (.md) I am adding:

type: = "article"

However I cannot seem to get this to work. I keep getting the Error:

Error calling where: can't evaluate the array by no match argument or more than or equal to two arguments

When compiling. Any ideas?

Is type: = "article" yaml or toml? To me it looks like a bit of both. – Laevogyrate

Not sure, I just coped the title: "Test Post" that was generated by hugo – Prothallus

Do you have any ideas on a solution to my problem? I'm literally pulling my hair our.... – Prothallus

Could you post the whole of your .md file metadata, including the separators? I have a feeling that is where at least part of your problems is. Also, you should only need one "range" statement, but I'll need to actually test that before I can give you a good answer. – Laevogyrate

Answer 1

Just for people running into this old question: the position of the 'or' is wrong. The right syntax is or condition1 condition2, see https://gohugo.io/functions/go-template/or/.
