send an array via $http.post in angular to django view

Question

I want to send this request to a django view:

$http({
        method: "post",
        url: "/enterprises/vouchers/_send",
        data: {
            group_id: group_id,
            group_student_ids: [1, 2, 3, 4]
        }
    }).success(function (response) {
        console.log("emails are sent. please check");
    }).error(function () {
        console.log("failed")
    });

In the view I assign them like this:

group_student_ids = request.POST['group_student_ids']
group_id = request.POST['group_id']

"group_id" is assigned as expected but django is throwing MultiValueDictKeyError for the aray object(group_student_ids)

How do I send an array via a post request?

Answer 1

This should work:

First, change your data to:

data: {
    'group_id': group_id,
    'group_student_ids[]': [1, 2, 3, 4]
}

and in your view:

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

Edit:

Just did some tests in my app; if I print request.POST, I'll get

<QueryDict: {'group_student_ids[]': ['1', '2', '3', '4']}>

And type(group_student_ids) would give <class 'list'>
