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

问题描述

我有这个:

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,
    })

此表单提交消息并返回同一页面.我的问题是提交后我再次看到我的字段充满了我的信息.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.

只需在成功时返回一个重定向到您的表单即可.

Just return a redirect to your form on success.

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