Add support for inline partials in content adapters #14480
Description
After discussion in https://discourse.gohugo.io/t/using-inline-partials-in-content-adapters/56693 I'd like to propose the following feature (text copied from that post):
I’m experimenting with Content Adapters, specifically I’d like to be able to use Go templates and pass these as the content to the .AddPagemethod. I came up with a simple example based on a combination of the examples in https://gohugo.io/content-management/content-adapters/#addpage and https://gohugo.io/functions/go-template/define/#article as follows, which I added to content/test/_content.gotmpl:
{{ define "_partials/inline/foo.html" }}
{{ printf "The _Hunchback of Notre Dame_ was written by Victor Hugo in %v." .answer }}
{{ end }}
{{ $content := dict
"mediaType" "text/markdown"
"value" (partial "inline/foo.html" (dict "answer" 1831))
}}
{{ $page := dict
"content" $content
"kind" "section"
"path" "../test"
"title" "The Hunchback of Notre Dame"
}}
{{ .AddPage $page }}
Unfortunately, this results in the following error message:
error building site:
process: readAndProcessContent: "/content/test/_content.gotmpl:7:11":
template: /content/test/_content.gotmpl:7:11:
executing "/content/test/_content.gotmpl" at <partial "inline/foo.html" (dict "answer" 1831)>:
error calling partial: partial "inline/foo.html" not found
According to @bep this is currently not supported, but could possibly be added.
