calling ajax function in views.py to get the data from database - django

Question

I want to fetch data from the database. I am using ajax function to get it in the index.html. How should I call this ajax function to the views.py so i can display it in view. How should I attain it?
My codes:
index.html
<script type="text/javascript">
function submitData(){
// Get answer from the input element
var dt = document.getElementById("major1").value;
var dtt = document.getElementById("major2").value;
var dttt = document.getElementById("major3").value;
var dtttt = document.getElementById("major4").value;
var dttttt = document.getElementById("major5").value;
// add the url over here where you want to submit form .
var url = "{% url 'home' %}";
$.ajax({
url: url,
data: {
'major1': dt,
'major2': dtt,
'major3': dttt,
'major4': dtttt,
'major5': dttttt,
},
dataType: 'JSON',
success: function(data){
// show an alert message when form is submitted and it gets a response from the view where result is provided and if url is provided then redirect the user to that url.
alert(data.result);
if (data.url){
window.open(data.url, '_self');
}
}
});
}
</script>
views.py:
def home(request):
majors = Major.objects.filter(percentages__isnull=False).distinct().order_by("pk")
if request.method == 'POST':
form = request.POST.get('be_nextyr_total')
line_chart = pygal.Line(width=1500)
line_chart.title = 'Budget Estimation'
context = {
"chart": line_chart.render_data_uri(),
'majors': majors
}
return render(request, "website/index.html" , context )

If you are doing a post request with Ajax, then you have to write in your ajax code like
type: "POST",
if you want to access your form data in view than you have to write
request.POST.get('your_variable_name_like_major1')
