I need to get all checked objects from checkboxes placed in table, and pass them to hyperlinks in navbar.
For example, I have hyperlink "Delete selected". I want to delete every questionnaire which is selected by clicking on that link. Is it possible? If yes how can I do that?

In order to achieve, 'I have hyperlink "Delete selected". I want to delete every questionnaire which is selected by clicking on that link.', it's going to require a mix of jQuery and Django.
You should attach a click listener on the 'Delete selected' button which should serialize all selected questionnaires and send that data via AJAX to a Django view which will delete the necessary questionnaire objects from the database.
Here is a rough example...
<script type="text/javascript">
$(document).ready(function() {
$('.btn-danger').click(function() {
$.post('url/to/django/view', $('input[name=questionnaires]').serialize(), function(data, textStatus, jqXHR) {
// DO STUFF VIA THIS CALLBACK
});
});
});
</script>
def url/to/django/view(self, request):
if request.method == 'POST':
questionnaires_to_delete = request.POST.getlist('questionnaires')
Questionnaire.objects.filter(id__in=questionnaires_to_delete).delete()
return HttpResponse('WHATEVER YOU WANT TO RETURN TO THE CLIENT')
You many run into CSRF issues depending on your setup. Here is the documentation for handling that...
