I want to return a string. I've never done this before. I've been
reading examples on the web and I came up with this:

$.ajax({
url: 'permalink/',
type: 'GET',
data: {
report: "{% url motor.core.reports.views.view
the_controller.app.name the_controller.get_name %}",
params: "{{ the_report.params_string }}"
},
dataType: 'json',
success: function (data) {
setTimeout(function () {
alert(data);
}, 0);
}
});

In my function I first tried returning just the string, but that was
causing a 500 error. Then I tried this:

return HttpResponse(content=data, content_type="text/plain", status=201)

I don't get the error, but the ajax success function does not seem to be called.
