在 Django 中提交后如何保留字段值？

Question

I have a form and I would like to keep the values of the fields after a click on submit. How can I do this?

Views.py:

if request.method == "POST":
    form = MyForm(request.POST)
    if form.is_valid():
        form.save()
else:
    form = MyForm()

template.html

<form method="post" id="Myform" >
    {{form}}
    <button class="btn btn-primary" type="submit" >
</form>

Answer 1

Moving initial form assignment outside the check for the POST method should do.

form = MyForm(request.POST or None)
if request.method == "POST":
    if form.is_valid():
        form.save()
