I got the solution from Daniel Rossman on SO:
Firstly, use `render_to_string` to get the template fragment as an HTML
string. Secondy, serialize your object as a Python dict, not JSON. Then you
can convert the whole lot to JSON in one go.
html = render_to_string("page_content.html", {'form': form},
context_instance=RequestContext(request))
param = serializers.serialize('python', object)
data = json.dumps({'html': html, 'param': param})
return StreamingHttpResponse(data, content_type="application/json")
Now your JS can parse the JSON and access the `html` and `param` values.
