copying a property value verbatim

[Julian Lyndon-Smith]

If I have got a variable that is a json array

data.foo = ["a","b","c"]

and I have this code in my template

{% if data.foo and data.foo.length > 0 %}
 controller.foo  = {{ data.foo }}
{% endif %}

I get the following code generated;

controller.foo = a,b,c


whereas I wanted to get

controller.foo = ["a","b","c"]


is there any way of telling nunjucks to export the variable value as a json string ?

and the minute I post, I get an idea of how to do it ...

function JSONStringify(data) {
 return JSON.stringify(data)
}

data.JSONStringify = JSONStringify

nj.render(templateName,data,function(err,res) {
 cb(err,res)
 })
}

and in the template

{% if data.foo and data.foo.length > 0 %}

 controller.foo  = {{ JSONStringify(data.foo) }}
{% endif %}

hope this helps someone
