Django 表单集单元测试

Question

我无法使用 formset 运行单元测试。
我尝试做一个测试:

class NewClientTestCase(TestCase):
    
    def setUp(self):
        self.c = Client()

    def test_0_create_individual_with_same_adress(self):
        
        post_data =  {
            'ctype': User.CONTACT_INDIVIDUAL,
            'username': 'dupond.f',        
            'email': 'new@gmail.com', 
            'password': 'pwd', 
            'password2': 'pwd', 
            'civility': User.CIVILITY_MISTER, 
            'first_name': 'François', 
            'last_name': 'DUPOND', 
            'phone': '+33 1 34 12 52 30', 
            'gsm': '+33 6 34 12 52 30', 
            'fax': '+33 1 34 12 52 30', 
            'form-0-address1': '33 avenue Gambetta', 
            'form-0-address2': 'apt 50', 
            'form-0-zip_code': '75020', 
            'form-0-city': 'Paris', 
            'form-0-country': 'FRA', 
            'same_for_billing': True,            
        }
        
        response = self.c.post(reverse('client:full_account'), post_data, follow=True)   

        self.assertRedirects(response, '%s?created=1' % reverse('client:dashboard'))

我有这个错误:

ValidationError: [u'ManagementForm data is missing or has beentampered with']

我的看法 :

def full_account(request, url_redirect=''):    
    from forms import NewUserFullForm,  AddressForm,  BaseArticleFormSet
    
    fields_required = []
    fields_notrequired = []
    
    AddressFormSet = formset_factory(AddressForm, extra=2,  formset=BaseArticleFormSet)
    
    if request.method == 'POST':        
        form = NewUserFullForm(request.POST)        
        objforms = AddressFormSet(request.POST)            
       
        if objforms.is_valid() and form.is_valid():            
            user = form.save()            
            address = objforms.forms[0].save()

            
            if url_redirect=='':
                url_redirect = '%s?created=1' % reverse('client:dashboard')
                logon(request, form.instance)            
            return HttpResponseRedirect(url_redirect)
    else:
        form = NewUserFullForm()
        objforms = AddressFormSet()   
    
    return direct_to_template(request, 'clients/full_account.html', {
        'form':form,
        'formset': objforms, 
        'tld_fr':False, 
    })

和我的表单文件:

class BaseArticleFormSet(BaseFormSet):

    def clean(self):        
        
        msg_err = _('Ce champ est obligatoire.')
        non_errors = True
        
        if 'same_for_billing' in self.data and self.data['same_for_billing'] == 'on':
            same_for_billing = True
        else:            
            same_for_billing = False
        
        for i in [0, 1]:
            
            form = self.forms[i]           
            
            for field in form.fields:                                
                name_field = 'form-%d-%s' % (i, field )
                value_field = self.data[name_field].strip()                
                
                if i == 0 and self.forms[0].fields[field].required and value_field =='':                    
                    form.errors[field] = msg_err                    
                    non_errors = False
                    
                elif i == 1 and not same_for_billing and self.forms[1].fields[field].required and value_field =='':
                    form.errors[field] = msg_err                    
                    non_errors = False
        
        return non_errors

class AddressForm(forms.ModelForm):

    class Meta:
        model = Address

    address1 = forms.CharField()
    address2 = forms.CharField(required=False)
    zip_code = forms.CharField()
    city = forms.CharField()
    country = forms.ChoiceField(choices=CountryField.COUNTRIES,  initial='FRA')

每个 Django 表单集都带有一个需要包含在帖子中的管理表单。 official docs解释得很好。要在单元测试中使用它，您要么需要自己写出来。 (我提供的链接显示了一个示例)，或调用 formset.management_form输出数据。
