if request.method == 'POST':
    expectedphraseform = ExpectedphraseForm(request.POST)
    bannedphraseform = BannedphraseForm(request.POST)
    if expectedphraseform.is_valid():
        expectedphraseform.save()
        return HttpResponse("Success")
    if bannedphraseform.is_valid():
        bannedphraseform.save()
        return HttpResponse("Success")
else:
    bannedphraseform = BannedphraseForm()
    expectedphraseform = ExpectedphraseForm()
return render(request, 'some.html',{'bannedphraseform':bannedphraseform, 'expectedphraseform':expectedphraseform})

这完全符合我的要求。这种方法有一个问题，即它验证了表单的两个错误。但工作完全没问题。

一个供将来参考的方法是这样的。禁止的短语形式是第一个，期望的短语形式是第二个。如果第一个被击中，第二个就会被跳过(在这种情况下这是一个合理的假设):

if request.method == 'POST':
    bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
    if bannedphraseform.is_valid():
        bannedphraseform.save()
else:
    bannedphraseform = BannedPhraseForm(prefix='banned')

if request.method == 'POST' and not bannedphraseform.is_valid():
    expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
    bannedphraseform = BannedPhraseForm(prefix='banned')
    if expectedphraseform.is_valid():
        expectedphraseform.save()

else:
    expectedphraseform = ExpectedPhraseForm(prefix='expected')

我需要在同一页面上独立验证多个表单。我忽略的关键概念是:1)使用表单前缀作为提交按钮名称;2)无界表单不会触发验证。如果它对其他人有帮助，这里是我使用TemplateView的两个表单AForm和BForm的简化示例，基于@adam-nelson和@daniel-sokolowski的回答和@zeraien (https://stackoverflow.com/a/17303480/2680349):)的评论

# views.py
def _get_form(request, formcls, prefix):
    data = request.POST if prefix in request.POST else None
    return formcls(data, prefix=prefix)

class MyView(TemplateView):
    template_name = 'mytemplate.html'

    def get(self, request, *args, **kwargs):
        return self.render_to_response({'aform': AForm(prefix='aform_pre'), 'bform': BForm(prefix='bform_pre')})

    def post(self, request, *args, **kwargs):
        aform = _get_form(request, AForm, 'aform_pre')
        bform = _get_form(request, BForm, 'bform_pre')
        if aform.is_bound and aform.is_valid():
            # Process aform and render response
        elif bform.is_bound and bform.is_valid():
            # Process bform and render response
        return self.render_to_response({'aform': aform, 'bform': bform})

# mytemplate.html
<form action="" method="post">
    {% csrf_token %}
    {{ aform.as_p }}
    <input type="submit" name="{{aform.prefix}}" value="Submit" />
    {{ bform.as_p }}
    <input type="submit" name="{{bform.prefix}}" value="Submit" />
</form>

如果你正在使用基于类的视图和不同的“动作”attrs方法，我的意思是

在这两个表单的操作中放入不同的url。然后你会有两个不同的视图函数来处理这两个不同的表单。

你可以使用重载get_context_data方法，e.x轻松处理来自不同表单的错误:

views.py:

class LoginView(FormView):
    form_class = AuthFormEdited
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(LoginView, self).dispatch(request, *args, **kwargs)

    ....

    def get_context_data(self, **kwargs):
        context = super(LoginView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = True
        return context

class SignInView(FormView):
    form_class = SignInForm
    success_url = '/'
    template_name = 'main/index.html'

    def dispatch(self, request, *args, **kwargs):
        return super(SignInView, self).dispatch(request, *args, **kwargs)

    .....

    def get_context_data(self, **kwargs):
        context = super(SignInView, self).get_context_data(**kwargs)
        context['login_view_in_action'] = False
        return context

模板:

<div class="login-form">
<form action="/login/" method="post" role="form">
    {% csrf_token %}
    {% if login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
    .....
    </form>
</div>

<div class="signin-form">
<form action="/registration/" method="post" role="form">
    {% csrf_token %}
    {% if not login_view_in_action %}
        {% for e in form.non_field_errors %}
            <div class="alert alert-danger alert-dismissable">
                {{ e }}
                <a class="panel-close close" data-dismiss="alert">×</a>
            </div>
        {% endfor %}
    {% endif %}
   ....
  </form>
</div>

你有几个选择:

在这两个表单的操作中放入不同的url。然后你会有两个不同的视图函数来处理这两个不同的表单。 从POST数据中读取提交按钮值。你可以知道哪个提交按钮被点击了:我如何构建多个提交按钮django form?

观点:

class AddProductView(generic.TemplateView):
template_name = 'manager/add_product.html'

    def get(self, request, *args, **kwargs):
    form = ProductForm(self.request.GET or None, prefix="sch")
    sub_form = ImageForm(self.request.GET or None, prefix="loc")
    context = super(AddProductView, self).get_context_data(**kwargs)
    context['form'] = form
    context['sub_form'] = sub_form
    return self.render_to_response(context)

def post(self, request, *args, **kwargs):
    form = ProductForm(request.POST,  prefix="sch")
    sub_form = ImageForm(request.POST, prefix="loc")
    ...

模板:

{% block container %}
<div class="container">
    <br/>
    <form action="{% url 'manager:add_product' %}" method="post">
        {% csrf_token %}
        {{ form.as_p }}
        {{ sub_form.as_p }}
        <p>
            <button type="submit">Submit</button>
        </p>
    </form>
</div>
{% endblock %}
