Use the Store method on a Site object to create a scratch pad to store and manipulate data, scoped to the current site. To create a scratch pad with a different scope, refer to the scope section below.

Methods

{{ site.Store.Add "greetings" (slice "Welcome" "Cheers") }}
{{ site.Store.Get "greetings" }} → [Hello Welcome Cheers]

SetInMap

{{ site.Store.SetInMap "greetings" "english" "Hello" }}
{{ site.Store.SetInMap "greetings" "french" "Bonjour" }}
{{ site.Store.Get "greetings" }} → map[english:Hello french:Bonjour]

Determinate values

The Store method is often used to set scratch pad values within a shortcode template, a partial template called by a shortcode template, or by a render hook template. In all three cases, the scratch pad values are indeterminate until Hugo renders the page content.

If you need to access a scratch pad value from a parent template, and the parent template has not yet rendered the page content, you can trigger content rendering by assigning the returned value to a noop variable:

{{ $noop := .Content }}
{{ site.Store.Get "mykey" }}

You can also trigger content rendering with the ContentWithoutSummary, FuzzyWordCount, Len, Plain, PlainWords, ReadingTime, Summary, Truncated, and WordCount methods. For example:

{{ $noop := .WordCount }}
{{ site.Store.Get "mykey" }}
