How do we make a htmx response trigger a form reset?
I am creating a very basic Django messaging application, and would like to use htmx to send and render messages. I am able to post, save the message, and render the partial message without issue. However, I am running into a weird problem where my form textarea is not being reset. So, I would send a message, and after the swap is inserted, my old message would still be in the textarea. This isn't very ideal! I tried to manually clear the textarea by adding an onclick event like so: Html <div id="new-message-div"></div> <form id="message-form" class="chat-form rounded-pill bg-dark" data-emoji-form="" hx-post="{% url "chat:create-message" object.pk %}" hx-target="#new-message-div"> ... {{ message_form }} ... <button class="btn btn-icon btn-primary rounded-circle ms-5" type="submit" onclick="submitForm()"> </button> </form> Script (https://stackoverflow.com/a/14589251/12758446) <script> function submitForm() { var message_form = document.getElementById('message-form'); message_form.submit(); // Submit the form message_form.reset(); // Reset all form data return false; // Prevent page refresh } </script> Despite having the message_form.submit() in the submitForm(), my form is not being submitted, but the textarea is getting reset. Question: How would I go about getting my textarea reset after successfully sending and rendering a message?

Django login + pasword
[enter image description here][1] [1]: https://i.stack.imgur.com/ECii0.jpg Всем привет уважаемые коллеги! Сразу хочу сказать что, я недавно в IT и только учусь, прошу не употреблять профессиональные выражения, в решении данного вопроса, благодарен заранее! Я развернул проект Django, создал свой проект, хочу свой проект видоизменить, понимаю что основные файлы django лучше не изменять, по этому в корень своего проекта скинул копии файлов: login.html, base.html, base_site.html а так же в папку проекта скопировал файлы стилей: login.css и base.css. Связываю HTML файлы с CSS стилями, но при запуске своего проекта, все равно загружаются CSS файлы django. Подскажите где я ошибся и что делаю не так?
