Works in parts!

this is awesome trick for datatables server side on django
sorry please correct the js client code if type POST request

"ajax": {
        "url": "{% url 'app_url:ajax_web_list' %}",
        "type": "post",
        "data": {
            "csrfmiddlewaretoken": "{{ csrf_token }}"
        }
    }

"ajax": {
        "url": "{% url 'app_url:ajax_web_list' %}",
        "type": "get",
    }

Where you use start variable?

Is this working perfectly?

Does not work for me!

Pagination it's wrong, you need to change to this:

page_number = start / length + 1

try:
    object_list = paginator.page(page_number).object_list
except PageNotAnInteger:
    object_list = paginator.page(1).object_list
except EmptyPage:
    object_list = paginator.page(1).object_list

Thank you for coding of datatables with Django.
I run to above code . But line of "draw = int(datatables.get('draw')) " take following errors.
"TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'"

hi, thanks for the code, it works after applied the solution in comment sections (also thanks to contributor) , it really help me!

btw, the sorting does not work , so i add these lines :

• Ambil data untuk ordering

`

order_idx = int(datatables.get('order[0][column]'))
order_dir = datatables.get('order[0][dir]')
order_col = 'columns[' + str(order_idx) + '][data]'
order_col_name = datatables.get(order_col)

if (order_dir == "desc"):
  order_col_name =  str('-' + order_col_name)

... (code filtering data)

• after data filterred , apply order
  datas = datas.order_by(order_col_name)

it's just there is still this bug, the data in first row is not sorted. still try to figure out the solutions

update, i found this column filtering in datatables but it's for client side rendering ( https://datatables.net/extensions/fixedheader/examples/options/columnFiltering.html )
so i added it to able using server side, cont from code above

        idx=0
        for itemcol in datatables:
            colname = 'columns['+str(idx)+'][data]'
            colsearchval = 'columns['+str(idx)+'][search][value]'

            colname = datatables.get(colname)
            colsearchval = datatables.get(colsearchval)
            if (colsearchval):
                search_type = 'icontains'
                filter = colname + '__' + search_type
                datas=datas.filter(**{ filter: colsearchval })

                records_total = datas.count()
                records_filtered = records_total

            idx+=1
