Issues posting comment with ajax through django - ajax

Question

I am relatively new to this, but I'm working through things. I want to get solid understanding of how things work.
That being said, I have been attempting to get Django to post comments with an ajax hook.
I thought I was close to accomplishing this but, nothing so far. I was able to write a view that would save a posted comment then redirect me to my main page. I want to be able to use ajax so that the comment would post in a facebook style.
def add_comment(request, pk):
if request.method == 'POST' and request.is_ajax():
comment_form = CommentForm(request.POST)
if comment_form.is_valid():
comment = comment_form.save(commit=True)
comment.save()
json = simplejson.dumps(comment, ensure_ascii=False)
return HttpResponse(json, mimetype='application/json')
return render_to_response(simplejson.dumps('{{ post.id }}', {'comment': comment,}), context_instance=RequestContext(request), mimetype='application/json')
This view is pretty rough right now. I don't have any calls to json but, read this might be the way to go.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script></javascript>
<script type="text/javascript">
$(document).click(function()
{
$('#comment_form').submit(function()
{
var dataString = $('#comment_form').serialize();
$.ajax({
type: 'POST',
url: '{{ post.id }}',
data: dataString,
success: function(data){
$('{{ post.id }}').html(data);
},
});
return false;
});
});
</script>
<form action="" method="POST" id="comment_form">{% csrf_token %}
<div id="cform">
Name: {{ form.author }}
<p>{{ form.body|linebreaks }}</p>
</div>
<div id="submit"><input type="submit" value="Submit"></div>
</form>

Thanks for the response, next time I will definitely leave a more detailed post. My problem was in the jquery script. I was trying to pass dataString as form data to the view, when it was a DOM object not the actual form data. Here's the final working script.
$(document).ready(function() {
$('#comment_form').submit(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: '{% url art.views.post %}',
data: $('#comment_form').serialize(),
dataType: 'json',
success: function() {
location.reload();
$('#comment_form').get(0).reset();
},
});
return false;
});
});
