Hi Steve,
I am new to Django as well. To do what you wanted to do (pass values from
python to js), I used ajax queries (using jquery) and then did a
JsonResponse to the ajax call. The ajax call then handles the data as
required.
Sample usage:
VIEWS.PY:
class InstructorDeleteView(DeleteView):
model = Instructor
success_url = reverse_lazy('instructor_list')
template_name = 'class_management/instructor_list.html'
def delete(self, request, *args, **kwargs):
"""
Calls the delete() method on the fetched object and then
responds to the call with the relevant data.
"""
self.object = self.get_object()
pk = self.object.pk # Save the primary key before the object is
deleted.
self.object.delete()
data = {
'message': "Successfully deleted the instructor.",
'pk': pk,
}
return JsonResponse(data)
Then, in you template, you can add js and have a ajax call to the view
above so that it can receive the JsonResponse:
TEMPLATE:
$.ajax({
method: "POST",
url: $id + "/delete/",
data: $data,
success: handleSuccess,
error: handleError,
});
function handleSuccess(data, textStatus, jqXHR) {
console.log("SUCCESSFULLY DELETED INSTRUCTOR.");
console.log("Removing the deleted entry from the table.");
$('#row' + data['pk']).remove();
console.log(data);
console.log(textStatus);
console.log(jqXHR);
}
function handleError(jqXHR, textStatus, errorThrown) {
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown)
}
This was a POST request using AJAX and I am sure a GET request will work
fine as well.
Please note: There might be better alternatives out there. I just don't
know them yet :)
Best,
Akshay
