Use of dust.js parameters to set locale for strings in Json

Question

I have the following json structure:

{
 locale : "en",
 text {
     "en": "Hello",
     "fr": "Bonjour"
 }
}

I want to pick up the locale in my template and use it when accessing the text. I thought something like this might work:

{#text foo=locale}
    {text.foo}
{/text}

But I get nothing.

Any ideas? Thanks.

Answer 1

If you use the LinkedIn fork of Dust, you can simply do {text[locale]}. I tested this in the LinkedIn playground here.

Managed to solve it in the end with a helper function.

Helper function looks something like this:

dust.helpers.locale = function(chunk, ctx, bodies, params){
    var locale = params.loc;
    var text = params.txt;
    return chunk.write(text[locale]);
}

I can then call it from the template like so:

{@locale loc=locale txt=text /}

Not sure if there is a way of doing this without the helper but this seems to work fine.
