Django的基于类的视图提供了一个通用的FormView，但是出于所有的意图和目的，它被设计成只处理一个表单。

使用Django的通用视图处理具有相同目标action url的多个表单的一种方法是扩展'TemplateView'，如下所示;我经常使用这种方法，以至于我把它做成了Eclipse IDE模板。

class NegotiationGroupMultifacetedView(TemplateView):
    ### TemplateResponseMixin
    template_name = 'offers/offer_detail.html'

    ### ContextMixin 
    def get_context_data(self, **kwargs):
        """ Adds extra content to our template """
        context = super(NegotiationGroupDetailView, self).get_context_data(**kwargs)

        ...

        context['negotiation_bid_form'] = NegotiationBidForm(
            prefix='NegotiationBidForm', 
            ...
            # Multiple 'submit' button paths should be handled in form's .save()/clean()
            data = self.request.POST if bool(set(['NegotiationBidForm-submit-counter-bid',
                                              'NegotiationBidForm-submit-approve-bid',
                                              'NegotiationBidForm-submit-decline-further-bids']).intersection(
                                                    self.request.POST)) else None,
            )
        context['offer_attachment_form'] = NegotiationAttachmentForm(
            prefix='NegotiationAttachment', 
            ...
            data = self.request.POST if 'NegotiationAttachment-submit' in self.request.POST else None,
            files = self.request.FILES if 'NegotiationAttachment-submit' in self.request.POST else None
            )
        context['offer_contact_form'] = NegotiationContactForm()
        return context

    ### NegotiationGroupDetailView 
    def post(self, request, *args, **kwargs):
        context = self.get_context_data(**kwargs)

        if context['negotiation_bid_form'].is_valid():
            instance = context['negotiation_bid_form'].save()
            messages.success(request, 'Your offer bid #{0} has been submitted.'.format(instance.pk))
        elif context['offer_attachment_form'].is_valid():
            instance = context['offer_attachment_form'].save()
            messages.success(request, 'Your offer attachment #{0} has been submitted.'.format(instance.pk))
                # advise of any errors

        else 
            messages.error('Error(s) encountered during form processing, please review below and re-submit')

        return self.render_to_response(context)

html模板的效果如下:

...

<form id='offer_negotiation_form' class="content-form" action='./' enctype="multipart/form-data" method="post" accept-charset="utf-8">
    {% csrf_token %}
    {{ negotiation_bid_form.as_p }}
    ...
    <input type="submit" name="{{ negotiation_bid_form.prefix }}-submit-counter-bid" 
    title="Submit a counter bid"
    value="Counter Bid" />
</form>

...

<form id='offer-attachment-form' class="content-form" action='./' enctype="multipart/form-data" method="post" accept-charset="utf-8">
    {% csrf_token %}
    {{ offer_attachment_form.as_p }}

    <input name="{{ offer_attachment_form.prefix }}-submit" type="submit" value="Submit" />
</form>

...

这有点晚了，但这是我找到的最好的解决办法。您为表单名称及其类创建了一个查找字典，还必须添加一个属性来标识表单，并且在视图中必须使用form.formlabel将其作为一个隐藏字段添加。

# form holder
form_holder = {
    'majeur': {
        'class': FormClass1,
    },
    'majsoft': {
        'class': FormClass2,
    },
    'tiers1': {
        'class': FormClass3,
    },
    'tiers2': {
        'class': FormClass4,
    },
    'tiers3': {
        'class': FormClass5,
    },
    'tiers4': {
        'class': FormClass6,
    },
}

for key in form_holder.keys():
    # If the key is the same as the formlabel, we should use the posted data
    if request.POST.get('formlabel', None) == key:
        # Get the form and initate it with the sent data
        form = form_holder.get(key).get('class')(
            data=request.POST
        )

        # Validate the form
        if form.is_valid():
            # Correct data entries
            messages.info(request, _(u"Configuration validée."))

            if form.save():
                # Save succeeded
                messages.success(
                    request,
                    _(u"Données enregistrées avec succès.")
                )
            else:
                # Save failed
                messages.warning(
                    request,
                    _(u"Un problème est survenu pendant l'enregistrement "
                      u"des données, merci de réessayer plus tard.")
                )
        else:
            # Form is not valid, show feedback to the user
            messages.error(
                request,
                _(u"Merci de corriger les erreurs suivantes.")
            )
    else:
        # Just initiate the form without data
        form = form_holder.get(key).get('class')(key)()

    # Add the attribute for the name
    setattr(form, 'formlabel', key)

    # Append it to the tempalte variable that will hold all the forms
    forms.append(form)

我希望这将在未来有所帮助。

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>

根据@ybendana的回答:

同样，我们使用is_bound来检查表单是否能够进行验证。请参阅文档的这一部分:

绑定和未绑定的表单 Form实例可以绑定到一组数据，也可以不绑定。 如果它绑定到一组数据，它就能够验证该数据并将表单呈现为HTML，并在HTML中显示数据。 如果未绑定，则不能进行验证(因为没有数据要验证!)，但仍然可以将空白表单呈现为HTML。

我们为表单对象和它们的详细信息使用元组列表，这允许更多的可扩展性和更少的重复。

但是，我们没有重写get()，而是重写get_context_data()，从而将一个新的空白表单实例(带前缀)插入到响应中作为任何请求的默认操作。在POST请求的上下文中，我们重写POST()方法以:

使用前缀检查每个表单是否已经提交 验证已提交的表单 使用cleaned_data处理有效的表单 通过覆盖上下文数据向响应返回任何无效表单

# views.py

class MultipleForms(TemplateResponseMixin, ContextMixin, View):

    form_list = [ # (context_key, formcls, prefix)
        ("form_a", FormA, "prefix_a"),
        ("form_b", FormB, "prefix_b"),
        ("form_c", FormC, "prefix_c"),
        ...
        ("form_x", FormX, "prefix_x"),
    ]

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        # Add blank forms to context with prefixes
        for context_key, formcls, prefix in self.form_list:
            context[context_key] = formcls(prefix=prefix)
        return context

    def post(self, request, *args, **kwargs):
        # Get object and context
        self.object = self.get_object()
        context = self.get_context_data(object=self.object)
        # Process forms
        for context_key, formcls, prefix in self.form_list:
            if prefix in request.POST:
                # Get the form object with prefix and pass it the POST data to \
                # validate and clean etc.
                form = formcls(request.POST, prefix=prefix)
                if form.is_bound:
                    # If the form is bound (i.e. it is capable of validation)  \
                    # check the validation
                    if form.is_valid():
                        # call the form's save() method or do whatever you     \
                        # want with form.cleaned_data
                        form.save()
                    else:
                        # overwrite context data for this form so that it is   \
                        # returned to the page with validation errors
                        context[context_key] = form
        # Pass context back to render_to_response() including any invalid forms
        return self.render_to_response(context)
        

这种方法允许在同一页面上重复表单条目，我发现@ybendana的答案并不适用。

我相信，将这个方法折叠到一个Mixin类中，将form_list对象作为一个属性，并像上面那样挂钩get_context_data()和post()，不会有更多的工作。

编辑:这个已经存在了。请参阅此存储库。

注: 这个方法需要TemplateResponseMixin来实现render_to_response()，需要ContextMixin来实现get_context_data()。要么使用这些mixin，要么使用源自它们的CBV。

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')
