Answer 1

In urls.py you have to add the url that you will be calling. It could be something like:

url(r'^call-main/$', views.call_main, name='call-main')

And then the ajax call from the function that you wrote:

$.ajax({
    url: "{% url 'call-main' %}",
    type: "POST",
    data: { csrfmiddlewaretoken: '{{ csrf_token }}' },
    success: function () {
        // something here on success
    },
    error: function () {
       // something here on error
    }
});

Add your URL in urls.py

urlpatterns = [url(r'^sample/$', main, name='main_view')]

then use URL in the template

{% url main_view %}
