Remove Session Data Dictionary with ajax in Django

Question

I have an array with a data dictionary in my Session and would like to remove according to the row the user is going to click on a table where these values are displayed.

My view:

def deletar_servico_ou_item_selecionado(request):

    if request.is_ajax:
        linhaClicada = request.POST.get('item')
        lista = request.session['ord-serv']
        del lista[linhaClicada - 1]
        request.session['ord-serv'] = lista

    return HttpResponse("/")

My JS:

var linhaClicada = $(this).parent().index();
$.ajax({
    url: "/atendimento/deletar-servico-ou-item-selecionado/",
    type: "POST",
    data: {item: linhaClicada},
    success: function(response) {
        console.log("Success");
    },
    error: function(response) {
        console.log("Error");
    }
});

It seems my value doesn’t reach Django and I don’t know if I should use the type: "DELETE" in that case.

To remove the item from your list from the index, you can use list.pop, for example:

lista = [{"0":"0"},{"1":"1"},{"2":"2"},{"3":"3"},{"4":"4"},{"5":"5"}]
lista.pop(1)
# {'1': '1'}
lista
# [{'0': '0'}, {'2': '2'}, {'3': '3'}, {'4': '4'},{"5":"5"}]

If you do not need csrf_token in your request, you can include at the beginning of your function the @csrf_exempt, and import it from django.views.decorators.csrf import csrf_exempt. If yes, you must pass along with the data you are giving post. date : {csrfmiddlewaretoken: '{{ csrf_token }}'}
