Блог

я хочу отправить данные в мою базу данных mysql через django. Когда я запускаю сервер, я не получаю никаких ошибок. Когда я отправляю форму из hello.html , значения не хранятся в моей БД. в БД я получил таблицу hello_cont

hello.html

    {% block content %}
    <form action="/polls/" method="POST"> {% csrf_token %}
      <input class="form-control" id="name" name="name" placeholder="Name" type="text" required>
    </div>
    <div class="col-sm-6 form-group">
      <input class="form-control" id="email" name="email" placeholder="Email" type="email" required>
    </div>
  </div>
  <textarea class="form-control" id="comments" name="comments" placeholder="Comment" rows="5"></textarea><br>
  <div class="row">
    <div class="col-sm-12 form-group">
      <button class="btn btn-default pull-right" type="submit">Send</button>
    </form>
  

{% endblock %}
