How to preserve form fields in django after unsuccessful submit?

2024/10/13 3:29:31

Code from views.py:

def feedback(request):if request.method == "POST":form = CommentForm(request.POST)if form.is_valid():form.save()else:print("form.errors:", form.errors)else:form = CommentForm()articles = Comment.objects.all()ResponseDict = {"articles": articles, "form": form}return render_to_response("feedback.html", ResponseDict, context_instance = RequestContext(request))

I've tried this and several modifications from answers to similar questions, but nothing works. When I press submit button, all form fields in html become empty.

EDIT: code from feedback.html:

{% extends "base.html" %}
{% block main %}<table><form action="/feedback/" method="POST">{% csrf_token %}<div class="article"><label for="name">Ваше имя:</label><br /><input type="text" name="name" id="name" size="40" class="inputbox" value="" /><br /><!-- class="inputbox required" --><textarea class="WithoutTinymce" cols="50" rows="10" name="text" id="text"></textarea><br /><input type="submit" name="submit" value="Отправить"></div> <!-- /article --></form></table>{% include "articles.html" %}
{% endblock %}

I can also paste code from base.html if needed.

EDIT2: minimized code from base.html:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="cs" lang="cs">
...
<body id="body-id" onload="loaded()"><!-- Main -->
<div id="main" class="box"><div id="page" class="box"><div id="page-in" class="box"><!-- Content --><div id="content">{% block main %}{% endblock %}<hr class="noscreen" /></div> <!-- /content --></div> <!-- /page-in --></div> <!-- /page -->
</div> <!-- /Main -->
</body>
</html>
Answer

In your template you are not making use of form passed by the view.

You can update part of your template as (assuming your field names in the form are first_field and second_field.

<form action="/feedback/" method="POST">{% csrf_token %}<div class="article"><label for="name">Ваше имя:</label><br />{{ form.first_field.errors }}{{ form.first_field.label_tag }}: {{ form.first_field }}<br /><!-- class="inputbox required" -->{{ form.second_field.errors }}{{ form.second_field.label_tag }}: {{ form.second_field }}<br /><input type="submit" name="submit" value="Отправить"></div> <!-- /article -->
</form>
