  • I'm suspecting that something is wrong with the way you get your values. More on [here](https://stackoverflow.com/a/5895670). – crimsonpython24 Jul 21 '20 at 08:31
  • Please give details about how you send that value from – Smit Patel Jul 21 '20 at 08:39
  • from this code snippet, it looks that you are rendering the template, but not sending selected value back to server. there must me a form or ajax code to do that. – Smit Patel Jul 21 '20 at 08:40

First of all Do a little searching about 'Post' vs 'GET', TO know when to use each one. I recommend you to handle this with form.

    .Html file 
    <form action="PageObjects" method="post">
      <select >
        <option selected="selected" disabled>Objects on page:</option>
        <option value="10">10</option>
        <option value="20">20</option>
        <option value="30">30</option>
        <option value="40">40</option>
        <option value="50">50</option>
      </select>
      <input type="submit" value="Select">
    </form>

view.py
def page_objects(request):
  if request.method == 'POST':
    form = YourForm(request.POST)

    if form.is_valid():
      answer = form.cleaned_data['value']
