Error: Can't evaluate field Site in type []string

[UtkarshVerma]

I’m getting this error for some reason while building:

Building sites … ERROR 2018/05/13 19:11:36 Error while rendering "page" in "post/": template: /home/utkarsh/Website/blog/themes/dream-plus/layouts/post/single.html:37:8: executing "main" at <partial "tags.html" ...>: error calling partial: template: theme/partials/tags.html:1:34: executing "theme/partials/tags.html" at <.Site.Taxonomies.tag...>: can't evaluate field Site in type []string

Here is my partial tags.html:

{{ range $name, $taxonomy := .Site.Taxonomies.tags }}
<a class="ui label" href="{{ "/tags/" | relLangURL }}{{ $name | urlize }}" title="{{ $name }}">{{ $name }}</a>
{{ end }}

Update:

I’m also getting this as well:

Why no response?

Both look like a context issue.

[SOLVED] Accessing Page Variables inside with function

Hey guys I’m trying to access a Page variable inside a with function, but it doesn’t work. Is there anything I’m doing wrong? In my template file I call a partial inside the with function: {{ with .Params.homepage }} <div class="col-md-3"> {{ partial "faq/item.html" . }} </div> {{ end }} In the partial I try to access the Page Variable like this <div class="faq-panel"><img class="img-responsive" src="{{ .image }}"> <div class="faq-panel-content"> <h…

@pointyfar Yes, that’s my concern as well. Any tips for me, as a beginner, to avoid those. A few starter links would be helpful.

DISCLAIMER: I am no authority at golang, so I am explaining to the best of my understanding, please correct me if I am wrong.

As far as I understand, it seems that the context gets changed because you use the with function to change the context (this dot: {{ . }}).

Here is a simplified example of your second (updated) problem):

{{- with .Site.DisqusShortname -}}
<a href="{{ .Permalink }}></a>
{{- end }}

the context here is .Site.DisqusShortname, so .Permalink essentially refers to .Site.DisqusShortname.Permalink (which does not exist, hence it cannot evaluate it.

As for the first example, I am assuming that Site.Taxonomies.tags fails to evaluate because the context is already something other than the root (so you are probably in already within a {{ range ... }} or {{ with .. }}).

Hope this clears this up for future users. This article helped me understand it better: https://regisphilibert.com/blog/2018/02/hugo-the-scope-the-context-and-the-dot/
