Modal form remain in place after submit

Using Django Templates & Frontend
1

Hello everyone,

I have a modal form. After submitting this form, I want the bootstrap modal to remain in place and all fields to be readonly so that I cant change the fields but review them. How can I do that?

Thank you in advance.

home.html

<div class="modal fade bd-example-modal-xl" {% block modal-id %} id="addsampleModal" {% endblock modal-id %} tabindex="-1" aria-labelledby="addsampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-xl">
    <div class="modal-content">
      <div class="modal-header" {% block modal-style %} style="background-color: #add9ff;" {% endblock modal-style %}>
        <h5 class="modal-title" id="addsampleModalLabel">
            {% block modal-title %}
            <i class="fa-solid fa-database"></i>&nbsp;&nbsp; Add Sample data
            {% endblock modal-title %}
        </h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close">
          <span aria-hidden="true"></span>
        </button>
      </div> <!-- end modal header -->

        <form method="POST" {% block action %} action="/addsample_row" {% endblock action %} autocomplete="off">{% csrf_token %}

          <div class="modal-body">

-----------------------(There are codes here)-----------------------

<div class="modal-footer">
              <button type="submit" id="submit_disabled" class="btn btn-outline-dark">
                {% block btn2-action %}
                Add new sample
                {% endblock btn2-action %}
              </button>
              {% block resetbutton-action %}
              <button type="reset" class="btn btn-outline-warning" title="Reset">Clear form</button>
              {% endblock resetbutton-action %}
            </div> <!-- end modal footer -->

views.py

def addsample_row(request):
    if request.method == "POST":
        if request.POST.get('culture') \
            and request.POST.get('index_sample') \
            and request.POST.get('is_index_sample') \
            and request.POST.get('status'):

            sample = Samples()

            sample.culture = request.POST.get('culture')
            sample.index_sample = request.POST.get('index_sample')
            sample.is_index_sample = request.POST.get('is_index_sample')
            sample.status = request.POST.get('status')

            sample.save()

            messages.success(request, "New sample is added successfully!")

            return HttpResponseRedirect("/")
    else:
        return render(request, 'addsample.html')

If you don’t want this to be the result of a page refresh, then you would need to write the necessary JavaScript to submit the data from the form as an AJAX request, then upon receiving the appropriate response, change the fields to be read-only.
