How to lookup the current context in Nunjucks?

Question

In Handlebars you can use this to look up the current context.

How do you do the same in Nunjucks?

For example, if you wanted to dump the entire context as a JSON string:

<script>window.__config__ = {{ this | dump | safe }};</script>

(But this doesn't seem to work in Nunjucks.)

Answer 1

If you need context then you can add global function

var env = nunjucks.configure([...
...
env.addGlobal('getContext', function() { 
    return this.ctx;
})

And dump her result in template

{{ getContext() | dump| safe }}
