Send an array with ajax to my python function in django

Question

I'm trying to send an array to my python function inside views.py but I can't. It always crash with a keyError because is not recognising the data from js.

Code:

Python function in views.py:

def cargar_datos_csv(request):
    if request.method == 'POST':
        filtros = request.POST['node']
    print(filtros)
    ctx = {'A':filtros}
    return JsonResponse(ctx)

JS

var csrftoken = $("[name=csrfmiddlewaretoken]").val();
var frutas = ['Manzana', 'Banana'];
$.ajax({
    url: '/../../data_bbdd/',
    type: 'POST',
    headers:{"X-CSRFToken": csrftoken},
    data: {
        'node': frutas,
    },
    dataType: "json",
    cache: true,
    success: function(response) {
        coords = JSON.stringify(response.A);
        alert(coords);
    }
});

How can I send an array to my python function?

Thank you very much.

Because node is a list it will be posted as node[] by JQuery so you can get it using request.POST['node[]'] or request.POST.getlist('node[]')

More informations on why this is the behavior of JQuery on this stackoverflow's answer :django - getlist()
