Python 测试Django内联模型表单：如何安排POST数据？

我有一个Django的“添加业务”视图，它使用内嵌的“业务联系人”表单添加了一个新业务

表单工作得很好，但我想知道如何编写单元测试——特别是发送到self.client.post（settings.BUSINESS\u ADD\u URL，postdata）的“postdata”

我已经检查了浏览器中的字段，并尝试添加具有相应名称的post数据，但在运行时仍然出现“ManagementForm数据丢失或已被篡改”错误

有人知道如何发布内联数据的资源吗

相关模型、视图和表格（如有帮助）。谢谢

型号：

class Contact(models.Model):
    """ Contact details for the representatives of each business """
    first_name = models.CharField(max_length=200)
    surname = models.CharField(max_length=200)
    business = models.ForeignKey('Business')
    slug = models.SlugField(max_length=150, unique=True, help_text=settings.SLUG_HELPER_TEXT)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    phone = models.CharField(max_length=100, null=True, blank=True)
    mobile_phone = models.CharField(max_length=100, null=True, blank=True)
    email = models.EmailField(null=True)
    deleted = models.BooleanField(default=False)
    class Meta:
        db_table='business_contact'

    def __unicode__(self):
        return '%s %s' % (self.first_name, self.surname)

    @models.permalink
    def get_absolute_url(self):

    def get_absolute_url(self):

观点：

def business_add(request):
    template_name = 'business/business_add.html'
    if request.method == 'POST':
        form = AddBusinessForm(request.POST)
        if form.is_valid():
            business = form.save(commit=False)
            contact_formset = AddBusinessFormSet(request.POST, instance=business)
            if contact_formset.is_valid():
                business.save()
                contact_formset.save()
                contact = Contact.objects.get(id=business.id)
                business.primary_contact = contact
                business.save()
                #return HttpResponse(help(contact))
                #business.primary = contact.id
                return HttpResponseRedirect(settings.BUSINESS_URL)
        else:
            contact_formset = AddBusinessFormSet(request.POST)
    else:
        form = AddBusinessForm()
        contact_formset = AddBusinessFormSet(instance=Business())
    return render_to_response(
            template_name,
            {
            'form': form,
            'contact_formset': contact_formset,
            },
            context_instance=RequestContext(request)
            )

表格：

class AddBusinessForm(ModelForm):
    class Meta:
        model = Business
        exclude = ['deleted','primary_contact',]

class ContactForm(ModelForm):
    class Meta:
        model = Contact
        exclude = ['deleted',]


AddBusinessFormSet = inlineformset_factory(Business,
        Contact,
        can_delete=False,
        extra=1,
        form=AddBusinessForm,
        )

问题是您的数据中没有包含管理表单。您需要包括

form-TOTAL\u FORMS

（表单集中的表单总数，默认值为2）、

form-INITIAL\u FORMS

（表单集中的表单初始数量，默认值为0）和

form-MAX\u NUM\u FORMS

（表单集中的表单最大数量，默认值为“”）
