[Django]-How to get an array in Django posted via Ajax

Quite old question but let me show you full working code for this. (Good for newbie 🙂

In your template

data = {
    'pk' : [1,3,5,10]
}

$.post("{% url 'yourUrlName' %}", data, 
    function(response){
        if (response.status == 'ok') {
            // It's all good
            console.log(response)
        } else {
            // Do something with errors
        }
    })

urls.py

urlpatterns = [
    url(r'^yourUrlName/', views.yourUrlName, name='yourUrlName'), #Ajax
]

views.py

from django.views.decorators.http import require_POST
from django.http import JsonResponse


@require_POST
def yourUrlName(request):
    array = request.POST.getlist('pk[]')

    return JsonResponse({
            'status':'ok',
            'array': array,
        })

Just use request.GET.getlist('data[]')

With newer versions of django I was finding that even @YellowCap suggestion of request.POST.getlist('data[]') wasn’t working for me.

However dict(request.POST)["data"] does work. Context here:
