                customize: function (doc) {
                    doc.styles = {
                        header: {
                            fontSize: 18,

                        subheader: {
                            fontSize: 13,
                            bold: true
                        },
                        quote: {
                            italics: true
                        },
                        small: {
                            fontSize: 8
                        },
                        tableHeader: {
                            bold: true,

                            alignment: 'center'
                        }
                    };
                    doc.content[1].table.widths = ['20%', '20%', '15%', '15%', '15%', '15%'];
                    doc.content[1].margin = [0, 35, 0, 0];
                    doc.content[1].layout = {};
                    doc['footer'] = (function (page, pages) {
                        return {
                            columns: [
                                {
                                    alignment: 'left',
                                    text: ['Fecha de creación: ', {text: date_now}]
                                },
                                {
                                    alignment: 'right',
                                    text: ['página ', {text: page.toString ()}, ' de ', {text: pages.toString ()}]
                                }
                            ],
                            margin: 20
                        }
                    });

                }
            },
            {
                text: '<i class="fas fa-reply"></i> Reiniciar',
                className: 'btn btn-danger btn-sm btnReset',
                action: function (e, dt, node, config) {
                    $ ('select[name="Actividades"]').val ('').trigger ('change.select2');
                    $ ('select[name="Meses"]').val ('').trigger ('change.select2');
                    $ ('select[name="search_horarios"]').val ('').trigger ('change.select2');
                    id_act = -1;
                    list_alumnos_inicio ();
                }
            },
            {
                text: '<i class="far fa-envelope"></i> Enviar',
                className: 'btn btn-warning btn-sm btnReset',
                action: function (e, dt, node, config) {
                    /*Abrir modal con listado de monitores para enviar email*/
                    listado_monitores ()
                    $ ('#myModalMonitores').modal ('show');
                }
            }
        ],
        columns: [
            {"data": "full_name"},
            {"data": "telf"},
            {"data": "email"},
            {"data": "fecha_nacimiento"},
        ],
        columnDefs: [
            {
                targets: [-1],
                class: 'text-center',
                orderable: false,
                render: function (data, type, row) {
                    var fecha = row.fecha_nacimiento;
                    const opciones = {year: 'numeric', month: 'long', day: 'numeric'};
                    const fomateada = new Date (fecha).toLocaleDateString ('es-ES', opciones);
                    return fomateada;
                }
            },
        ],

There I have the query of the DataTable and in that query, with that data, are the ones I want to send by email, I am working with Django, all the send function and the url is done, what I can't understand is how to send that list to the Django view. If someone helps me I would be very grateful.
