Variable Name in Site.Data

support
1

I am trying to implement a variable passing into the site.data.filename property. Is that doable? For example,

{{ range .Site.Data.stocks }} {{.name}} {{lang.NumFmt 2 .value}} {{lang.NumFmt 2 .change}} {{lang.NumFmt 2 .percentage}} {{end}}

The above is a code snippet to print data from a Json file used in a shortcode. However, what I want to do is pass a file name in my template or md file so that I can read different files with the same code.

Thanks!

Use the index function.

Thank you! I read here

I tried this code -

{{ index .Site.Data.locations .Params.location }}

But I get error unrecognized character in action: U+201C ‘“’

See https://discourse.gohugo.io/t/requesting-help/9132.

Let us see your code

Include a link to the source code repository of your project, because we really need the context of seeing your templates and partials to be able to help you. It is trivial to do a quick git clone on your repo, then run hugo server in your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.

If you can’t share your repository for whatever reason, consider creating a dummy repo that you can share, which reproduces the problem you’re experiencing.

Here is a shortcode I wrote it works perfectly. Except it is static I want to inject the filename as a variable -

Market Summary

{{ range .Site.Data.stocks }} {{end}}
Index Value Change Percentage
{{.name}} {{lang.NumFmt 2 .value}} {{lang.NumFmt 2 .change}} {{lang.NumFmt 2 .percentage}}

type or paste code here

Index Value Change Percentage
{{.name}} {{lang.NumFmt 2 .value}} {{lang.NumFmt 2 .change}} {{lang.NumFmt 2 .percentage}}

This isn’t what I asked for.

<h3>Market Summary</h3>
<table class="table table-dark">
    <thead>
         <tr>
        <th scope="col">Index</th>
        <th scope="col">Value</th>
        <th scope="col">Change</th>
        <th scope="col">Percentage</th>

      <tr>
        <td>{{.name}}</td>
        <td>{{lang.NumFmt 2 .value}}</td>
        <td>{{lang.NumFmt 2 .change}}</td>
        <td>{{lang.NumFmt 2 .percentage}}</td>
      </tr>
      {{end}}
    </tbody>
  </table>

{{ $filename := "stocks" }}
{{ range index .Site.Data $filename }}
  {{ .name }}
{{ end }}

Thank you! It worked! how do I replace the static string “stocks” and access something like Site.Data.Metadata.frontmattervariablename ?

I’m not sure that I understand your question. The index function takes one or more keys, so you can do something like:

{{ index .Site.Data "foo" "bar" "baz" }}

<h3>Market Summary</h3>
<table class="table table-dark">
    <thead>
         <tr>
        <th scope="col">Index</th>
        <th scope="col">Value</th>
        <th scope="col">Change</th>
        <th scope="col">Percentage</th>
      </tr>
    </thead>
    <tbody>
      {{ $filename := .Params.myvar }}
      {{ range index .Site.Data $filename }}
      <tr>
        <td>{{.name}}</td>
        <td>{{lang.NumFmt 2 .value}}</td>
        <td>{{lang.NumFmt 2 .change}}</td>
        <td>{{lang.NumFmt 2 .percentage}}</td>
      </tr>
      {{end}}
     </tbody>
  </table>

myvar has the value "stocks" that comes from a front matter variable. I get the following error - 

can’t evaluate field myvar in type interface {}

The goal is each md file will have a different filename so this routine will work for all pages.

It worked very well. Here is the revised code -

<h3>Market Summary</h3>
<table class="table table-dark">
    <thead>
         <tr>
        <th scope="col">Index</th>
        <th scope="col">Value</th>
        <th scope="col">Change</th>
        <th scope="col">Percentage</th>
      </tr>
    </thead>
    <tbody>
      {{ $filename := .Get "file" }}
      {{ range index .Site.Data $filename }}
      <tr>
        <td>{{.name}}</td>
        <td>{{lang.NumFmt 2 .value}}</td>
        <td>{{lang.NumFmt 2 .change}}</td>
        <td>{{lang.NumFmt 2 .percentage}}</td>
      </tr>
      {{end}}
     </tbody>
  </table>


I call the shortcode routine like so - 

{{< stocks file="stocks" >}}

Each day I will have a different JSON file for the Stock Summary. 

Thanks a lot!!
