Loading array of objects in Python from POST returns empty

Question

I am sending an array containing multiple object with POST Ajax like this:

var dateBooking = [];
    $(".dateBooking:enabled").each(function() {

        dateBooking.push({
            date: $(this).val(),
            hour: $(this).next('input').val()
        });
    });

    form_data.dateBooking = dateBooking;

$.ajax({
        url      :  "{% url "posts:book" %}",
        type  : 'POST',
        dataType : 'json',
        data     : form_data,
        success  : function(data, status){

        }

The data received in my Python View is like this:

<QueryDict: {'id': ['581'], 'dateBooking[0][hour]': [''], 'message': ['ttt'], 'dateBooking[0][date]': ['09/04/2018']}>

I can not access dateBooking. I tried:

dateBooking = request.POST.getlist('dateBooking[]')

which returns empty, and get gives an error.
