title: message notification after save button (python, html)
body: <pre><code>&lt;form name="import_csv" id = "import_csv" action = "{% url 'mission:import-csv' mission.id %}" method = "post" accept-charset="utf-8" enctype="multipart/form-data"&gt;
  {% csrf_token %}
  {{ form }}
  &lt;/form&gt;
  {% endblock %}
  {% if message %}
          &lt;div class="alert alert-success"&gt;{{ message }}&lt;/div&gt;
  {% endif %}
  </code></pre>
  
  <p>The {{message}} contains a message of " You have uploaded successfully". I want to show the message after save the file. Can someone please help me run this program correctly?</p>
