How to use variables in include?

[atr-one]

I try to use this template code (for Node JS):

res.render('index', {fname: 'include.smarty'});

{include file="$fname"}

Result:

Error: ENOENT: no such file or directory, open 'C:\OSPanel\domains\express\partials\$fname'

If I use it like this:

{include file="include.smarty"}

Returns normal response.

What could be the problem when using variables in include?

this plugin does not cover it. You need to write your own code for that. I had this problem and I just rewrote some functions.
