Go template - syntax for range

In Go template, I have a map setup like this:

{{$key}}map := make(map[string]interface{})

And I want to iterate through the map using this:

{{ range $mapKey, $mapValue := {{$key}}map}}

And I am getting this error:

unexpected "{" in range

Looks like it does not allow nested {{}} inside another {{}}. Is there anyway I can solve this issue ???

You cannot generate variable names to be used in templates using the template engine itself. You seem to be in need of having multiple maps, one for each $key. So, use a map of maps:

m := make(map[string]map[string]interface{})

where m[key] gives the map for the key.

Then you can do:

{{ range $mapKey, $mapValue := (index $.m $.key)}}
...
{{end}}
