In a template how do you access an outer scope while inside of a “with” or “range” scope?

Question

When inside a with or range, the scope of . is changed. How do you access the calling scope?

Answer 1

{{with .Inner}}
  Outer: {{$.OuterValue}}
  Inner: {{.InnerValue}}
{{end}}

$ is documented in the text/template docs:

When execution begins, $ is set to the data argument passed to Execute, that is, to the starting value of dot.

Answer 2

You can save the calling scope with a variable:

{{ $save := . }}
{{ with .Inner }}
  Outer: {{ $save.OuterValue }}
  Inner: {{ .InnerValue }}
{{ end }}
