What I do is something like this:
In controller action:
c.thing = thing
In Mako template:
<script>
var thing = JSON.parse(${h.to_json_string(c.thing)});
</script>
In helpers module:
def to_json_string(obj):
return literal(repr(json.dumps(obj)))
I use this helper because it properly backslash escapes things and also adds
the quotes around the JSON string, so what gets rendered is something like this:
<script>
var thing = JSON.parse('{"id": 13, "last_name": "O\'Leary"}');
</script>
Another option would be to render a JS file using Mako (being sure to set
the correct content type).
