在 Django 的一个页面上处理多个表单的正确方法 [英] Proper way to handle multiple forms on one page in Django

问题描述

我有一个需要两种形式的模板页面.如果我只使用一种形式，就像这个典型的例子一样:

I have a template page expecting two forms. If I just use one form, things are fine as in this typical example:

if request.method == 'POST':
    form = AuthorForm(request.POST,)
    if form.is_valid():
        form.save()
        # do something.
else:
    form = AuthorForm()

但是，如果我想处理多个表单，我如何让视图知道我只提交了一个表单而不是另一个(即它仍然是 request.POST 但我只想处理表单哪个提交发生了)?

If I want to work with multiple forms however, how do I let the view know that I'm submitting only one of the forms and not the other (i.e. it's still request.POST but I only want to process the form for which the submit happened)?

这是基于答案的解决方案，其中expectedphrase 和bannedphrase 是不同表单的提交按钮的名称，expectedphraseform 和 bannedphraseform 是形式.

This is the solution based on the answer where expectedphrase and bannedphrase are the names of the submit buttons for the different forms and expectedphraseform and bannedphraseform are the forms.

if request.method == 'POST':
    if 'bannedphrase' in request.POST:
        bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
        if bannedphraseform.is_valid():
            bannedphraseform.save()
        expectedphraseform = ExpectedPhraseForm(prefix='expected')
    elif 'expectedphrase' in request.POST:
        expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
        if expectedphraseform.is_valid():
            expectedphraseform.save() 
        bannedphraseform = BannedPhraseForm(prefix='banned')
else:
    bannedphraseform = BannedPhraseForm(prefix='banned')
    expectedphraseform = ExpectedPhraseForm(prefix='expected')

推荐答案

您有几个选择:

1. 在两个表单的操作中放置不同的 URL.然后你会有两个不同的视图函数来处理这两种不同的表单.

1. Put different URLs in the action for the two forms. Then you'll have two different view functions to deal with the two different forms.
