Django：使用 CreateView 创建两个模型

Question

我有一个用于创建客户的 CreateView，但我还需要与该客户一起创建一个“识别”模型。我有一个识别模型，该模型具有外键，因为我们需要能够向某些模型（驾驶执照、护照等）添加任意数量的 ID

无论如何，当前代码（仅创建一个新客户）如下所示：

class CustomerCreationView(CreateView):
    template_name = "customers/customer_information.html"
    form_class = CustomerInformationForm

    def get_context_data(self, *args, **kwargs):
        context_data = super(CustomerCreationView, self).get_context_data(*args, **kwargs)

        context_data.update({
            'new_customer': True,
        })

        return context_data

CustomerInformationForm 是 ModelForm。我想为标识创建另一个 ModelForm，但我不知道如何将第二个表单添加到 CreateView。我找到了这篇文章，但它已经有 5 年历史了，而且没有讨论 CreateView。

Answer 1

您可以使用

django-extra-views

中的 CreateWithInlinesView。代码如下所示：

from extra_views import CreateWithInlinesView, InlineFormSet


class IdentificationInline(InlineFormSet):
    model = Identification


class CustomerCreationView(CreateWithInlinesView):
    model = CustomerInformation
    inlines = [IdentificationInline]

Answer 2

class CustomerCreationView(CreateView):
    template_name = "customers/customer_information.html"
    form_class = CustomerInformationForm
    other_form_class = YourOtherForm

    def get_context_data(self, *args, **kwargs):
        context_data = super(CustomerCreationView, self).get_context_data(*args, **kwargs)

        context_data.update({
            'new_customer': True,
            'other_form': other_form_class,    
        })

        return context_data

Answer 3

class CustomerCreationView(CreateView):
    template_name = "customers/customer_information.html"
    form_class = CustomerInformationForm
   
    def get_context_data(self, *args, **kwargs):
        context_data = super(CustomerCreationView, self).get_context_data(*args, **kwargs)
        context_data["yournewform"] = YourNewForm(self.request.POST or None, self.request.FILES or None)
        return context_data

    def post(self, request, *args, **kwargs):
        form = self.get_form()
        yournewform = YourNewForm(request.POST, request.FILES)
        if form.is_valid() and yournewform.is_valid():
            '''
            # this is just example, you can change according to your model and form
            user = YourNewForm.save(commit=False)
            user.set_password(user.password)
            user.roll = 'parent'
            user.save()
            parent = form.save(commit=False)
            parent.user = user
            parent.save()
            messages.success(request, "Parent Created successfully")
            return redirect("parents")
            '''
        else:
            return render(request, self.template_name, {"form":form, "yournewform":yournewform})
