Cannot seem to delete an object: Django - html

Question

I have a list of items. Each item has a checkbox. I want to be able to delete an item using a button that deletes all check item (ones that are ticked). I have some jscript which does half of the work, but removing the item from my database is proving a lot of problems. When I press the the delete button, it removes the item. But when I open up the form again, the item returns again.
Here is my view.
def edit_order(request, order_no):
#some code
items = models.StorageItem.objects.filter(orderservicelist__order__pk = order.pk)
#some more code including if POST
item = models.StorageItem.objects.get(pk = id)
if request.POST.get('delete'):
item.delete()
And my template
{% extends "base_popup.html" %}
{% block title %}
{{title}}
{% endblock %}
{% block script %}
<script type="text/javascript" src="{{MEDIA_URL}}ui/ui.datepicker.min.js"></script>
<script type="text/javascript">
$(function(){
$("#id_required_date").datepicker({dateFormat:"dd/mm/yy"});
$(":checkbox").css("width","auto");
});
$(function(){
$("#check_all").click(function(){
if(this.checked ==true)
$("tbody :checkbox").each(function(){
this.checked=true;
});
else
$("tbody :checkbox").each(function(){
this.checked=false;
});
});
});
</script>
<script>
function hideCheckedRows() {
var checkboxes = document.getElementsByName("item");
var checkboxes_to_remove = new Array();
var count = 0;
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].checked == true) {
checkboxes_to_remove[count++] = checkboxes[i];
}
}
for (var i = 0; i < checkboxes_to_remove.length; i++) {
cbx = checkboxes_to_remove[i];
// parentNode.parentNode.parentNode is the <tr>
// parentNode.parentNode is the <td> containing the checkbox
cbx.parentNode.parentNode.parentNode.removeChild(cbx.parentNode.parentNode);
}
}
</script>

Answer 1

Your problem is that request.POST never contains the delete key.
Those type="button" elements need to be type="submit" to submit the form.
You're just hiding the elements with hideCheckedRows()
