Answer 1

Please see this answer if you were playing with API(Rest Framework of Django) I got this error and I solved it by changing True to False while serializing the object.

@api_view(['GET'])
def event_detail(request, pk):
    try:
        event = Event.objects.get(id=pk)
        # This is the line I have made changes True to False.
        serializer = EventSerializer(event, many=False)
        return Response(serializer.data)
    except:
        return render(request, "404_page.html")

You need to change here:

from django.shortcuts import render

def del_note(request, note_id):

    x = Note.objects.get(id = note_id)  # <-- Here
    print (x) // tried for degugging
    x.delete()
    return redirect("/")   


def edit_note(request, note_id):
    x = Note.objects.get( id = note_id) # <-- Here
    form = NoteForm(request.POST or None, instance=x)
    if request.method == "POST":
        if form.is_valid():
            form.save()
            return redirect("/")
    return render(request, 'edit_template.html', context={'form':form,'sticky':x})

 # edit_template.html
 <form action="{% url 'edit_note' sticky.id %}" method="POST">
      {% csrf_token %}
      <div class="inputContainer">
          {{ form.as_p }}
          <input type="submit" placeholder="Edit Note" value="Edit note">
      </div>
 </form>

The error was occurring because you passed id, but you should pass note_id instead.

Answer 3

You have to use note_id instead of id as below...

def del_note(request, note_id):
    x = Note.objects.get(id = note_id)
    # Your logic 


def edit_note(request, note_id):
    x = Note.objects.get(id = note_id)
    # Your logic

If you want to edit then you can do it like...

def edit_note(request, note_id):
    x = Note.objects.get(id = note_id)
    x.field_name_1 = new_val_1
    x.field_name_2 = new_val_2
    # and so on for other fields...
    x.save()


    # Your logic
