在Django提交后如何清除表单域 [英] How to clear form fields after a submit in Django

问题描述

我这样做：

def profile(request, username):
if request.method == 'POST':
    if request.user.is_authenticated():
        new_message = Message(author = request.user)
        form = MessagesForm(request.POST, instance = new_message)
    else:
        form = MessagesForm(request.POST)
    if form.is_valid():
        form.save()
else:
    to_user = User.objects.get(username = username)
    form = MessagesForm(initial = {'user': to_user.pk})


return render(request, "profile.html", {'username': username, 'form': form, 'messages': messages})

表单提交消息并返回相同的页面。我的问题是，在提交后，我再次看到我的字段填满了我的信息。提交后如何清除？

This form submit a message and return the same page. My problem is that after the submit I see again my field filled with my information. How to clear it after the submit?

推荐答案

表单提交后重定向是标准的，以防止重复。

It's standard to redirect after form submission to prevent duplicates.

只要将成功重定向到您的表单。

Just return a redirect to your form on success.

if form.is_valid():
    form.save()
    return http.HttpResponseRedirect('')
