Why is this variable not being passed in the POST request?

I am trying to do a simple POST request via AJAX, but I keep getting 500 errors. In an effort to figure out where the problem is, I added print statements after every if conditional. See my view below.

if request.is_ajax():
    print "request is ajax"
    object_name = request.POST.get('entryname')
    print object_name
    targetobject = Entry.objects.get(headline=object_name)
    if request.user.username == targetobject.author:
        print "current user is author" 
        targetobject.delete()
    return HttpResponseRedirect('/storefront/')

The only thing that prints to the console (other than the 500 error) is "request is ajax", and "None". This tells me that something is wrong with 'object_name' or 'entryname'. Below is the jQuery AJAX.

<script type="text/javascript">
    var my_app = {
      username: "{{ request.user.username }}"  
    };
</script>
<script>
 $(document).ready(function() {
    $(".delete_button").click(function() {
        var entryname = $(this).attr('id');
        $.ajax({
            type: "POST",
            url: "/accounts/" + my_app.username + "/listview/",
            data: {'entryname': entryname},
            csrfmiddlewaretoken: '{{ csrf_token }}'
        });
        return false;
    });
});
</script>

<a href="" class="delete_button" id="{{ i.headline }}">del</a>

And, this error in the console

DoesNotExist: Entry matching query does not exist.

Where did I go wrong? Is the error in the jQuery or my view method?

Your code looks like it's looking for the id of the element with class delete_button. Does your template contain an element with that class? If so, what is its id? That is the value that should be passed as entryname, but if there's no such element in your template then it would make sense that a value of None is being passed (as you mentioned in your comments). Try adding the delete_button class to your link tag.
