如何测试django模型表单？

我写了一个测试用例：

class MyTestCreateFilter(TestCase):

    def test_createfilter(self):
        test_filter = Filter(user_profile_id= 3,
        keyword = 'ca',
        industry = 'it',
        zip_code = '50002',
        distance = 30,
        creation_date = datetime.date.today(),
        last_run_date = datetime.date.today()
        )


        test_filter_form = FilterForm(instance=test_filter)

        self.assertEqual(test_filter_form.is_valid(), False)#without data
        test_filter_form = FilterForm({'user_profile_id':3,'keyword': 'ca','industry':'it','zip_code':'50002','distance':30,'creation_date': datetime.date.today(),
        'last_run_date': datetime.date.today() }, instance=test_filter)
        print test_filter_form.is_valid()

给出错误：

DoesNotExist: UserProfile matching query does not exist.

这是我的表格。如何编写测试用例：

class MyTestCreateFilter(TestCase):

    def test_createfilter(self):
        test_filter = Filter(user_profile_id= 3,
        keyword = 'ca',
        industry = 'it',
        zip_code = '50002',
        distance = 30,
        creation_date = datetime.date.today(),
        last_run_date = datetime.date.today()
        )


        test_filter_form = FilterForm(instance=test_filter)

        self.assertEqual(test_filter_form.is_valid(), False)#without data
        test_filter_form = FilterForm({'user_profile_id':3,'keyword': 'ca','industry':'it','zip_code':'50002','distance':30,'creation_date': datetime.date.today(),
        'last_run_date': datetime.date.today() }, instance=test_filter)
        print test_filter_form.is_valid()

类Filterforms.ModelForm：

class Meta:

    model=Filter

    exclude=('user_profile','creation_date','last_run_date')

    widgets = {
        'zip_code': forms.TextInput(attrs={'placeholder': "e.g.                     20708"}),
    }

def clean(self):

    user_profile = self.instance.user_profile

    keyword = self.cleaned_data.get("keyword")
    if Filter.objects.filter(user_profile=user_profile, keyword=keyword).exclude(id=self.instance.id).count() > 0:
        msg = u"A filter with that keyword already exists!"
        self._errors["keyword"] = self.error_class([msg])

    return self.cleaned_data

当我测试给出此错误的表单时：

user\u profile=self.instance.user\u profile get中的文件/usr/local/lib/python2.7/dist-packages/django/db/models/fields/related.py，第343行

如何解决此问题？

简单地创建模型对象不会在数据库中创建记录

使用.objects.create创建记录

test_filter = Filter.objects.create(
    user_profile_id= 3,
    keyword = 'ca',
    industry = 'it',
    zip_code = '50002',
    distance = 30,
    creation_date = datetime.date.today(),
    last_run_date = datetime.date.today()
)

或使用“保存”：

这可能有助于将模型应用于您的问题。以及完整的回溯。不。它不适合我。给出相同的错误

test_filter = Filter(...)
test_filter.save()
