Lightweight Django class for a full Datatables server processing implementation
Project description
# Django Datatables server processing
Lightweight Django class for a full Datatables server processing implementation.
https://datatables.net/examples/data_sources/server_side.html
After hanging around for a good integration of Datatables server processing in Django, I tested the things I found on internet but they all have the same problem, they cannot manage the ForeignKey relations as well. After all, I made it by myself.
This code was tested on Datatables 1.10.+ and Django 1.10.+.
To get it works just put datatables in your html template, like this:
```html
<!-- jQuery -->
<script src="/statics/js/vendors/jquery/dist/jquery.min.js"></script>
<!-- Datatables -->
<script src="/statics/js/vendors/datatables.net/js/jquery.dataTables.js"></script>
<!-- Datatables -->
<script>
$(document).ready(function() {
$('.datatable-responsive-serverside').DataTable({
"aLengthMenu": [
[25, 50, 100, 500, ], // -1],
[25, 50, 100, 500, ] //"All"]
],
"paging": true,
"responsive": true,
"processing": true,
"serverSide": true,
"ajax": "{% url 'appnamespace:viewname_json' %}",
// POST METHOD EXAMPLE HERE
//~ "ajax": {
//~ url: "{% url 'appnamespace:viewname_json' %",
//~ method: 'post',
//~ data: function(args) {
//~ return {
//~ "args": JSON.stringify(args)
//~ };
//~ }
//~ },
});
});
</script>
```
