在Django中内联单元测试验证admin

我在django管理中添加了一些内联验证，如果模型实例上的某个字段不存在，则不会保存内联。我不想增加额外的最后期限，如果没有已经是最后期限：在Django中内联单元测试验证admin

class DeadlineInlineFormset(forms.models.BaseInlineFormSet): 
    def clean(self): 
     super(DeadlineInlineFormset, self).clean() 
     # make sure deadline is set 
     if not self.instance.deadline: 
      raise ValidationError(_("Doesn't validate")) 


class DeadlineInline(admin.StackedInline): 
    model = AdditionalDeadline 
    formset = DeadlineInlineFormset 


class GrantAdmin(admin.ModelAdmin): 
    ... 
    inlines = [DeadlineInline] 
    ...

这工作得很好，但我挣扎单元测试。到目前为止，我有：

class GrantAdminTestCase(TestCase): 

    fixtures = [...] 

    def test_forms(self): 
     # create the form from a model instance. 
     # it should validate but it doesn't 
     g = Grant.objects.first() 
     form = GrantAdminForm(instance=g) 
     self.assertEqual(form.is_valid(), True) 

     # remove deadline and add additional deadlines 
     # It shouldn't be valid because deadline is None 
     g.deadline = None 
     g.additional_deadlines.add(
      Deadline(deadline=datetime.now()) 
     ) 
     self.assertEqual(form.is_valid(), False)

即使模型实例有效，第一个断言失败。第二个断言通过但不应该因为它现在应该是无效的。所以一定是错误的。

我也不确定这是否是正确的做法。在模型中进行验证会更容易吗？甚至在形式而不是形式？

编辑：相当多的，这是不对的，我已经改变了一些东西，但它仍然没有工作：

def test_forms(self): 
    g = Grant.objects.first() 
    form = GrantAdminForm(model_to_dict(g)) 
    self.assertEqual(form.is_valid(), True) 

    DeadlineFormSet = inlineformset_factory(Grant, Deadline) 

    # should be invalid 
    g.deadline = None 
    g.additional_deadlines.add(Deadline(deadline=datetime.now())) 
    formset = DeadlineFormSet(instance=g) 
    self.assertEqual(formset.is_valid(), False) 

    # should be valid 
    g = Grant.objects.first() 
    formset = DeadlineFormSet(instance=g) 
    self.assertEqual(formset.is_valid(), True)

前两个断言通过，但最后却没有。

This使我这是答案：

class GrantAdminTestCase(TestCase): 
    fixtures = [ 
     'grants/grant_config', 
     'grants/grants', 
    ] 

    def setUp(self): 
     self.g = Grant.objects.first() 

     self.DeadlineFormSet = inlineformset_factory(
      Grant, Deadline, formset=DeadlineInlineFormset) 

     self.data = { 
      'additional_deadlines-INITIAL_FORMS': 0, 
      'additional_deadlines-MAX_NUM_FORMS': 1000, 
      'additional_deadlines-TOTAL_FORMS': 1, 
      'additional_deadlines-0-deadline': date.today(), 
      'additional_deadlines-0-grant': '2', 
      'additional_deadlines-0-id': '', 
     } 

    def test_formset_is_valid_if_deadline_exists(self): 
     formset = self.DeadlineFormSet(self.data, instance=self.g) 
     self.assertEqual(formset.is_valid(), True) 

    def test_formset_is_invalid_if_deadline_doesnt_exist(self): 
     # formset should be invalid if there is an additional deadline 
     # and no main deadline 
     self.g.deadline = None 
     formset = self.DeadlineFormSet(self.data, instance=self.g) 
     self.assertEqual(formset.is_valid(), False) 

    def test_formset_is_valid_if_deadline_blank(self): 
     # formset should still be valid if deadline is blank 
     # (it's not saved) 
     self.data['additional_deadlines-0-deadline'] = '' 
     formset = self.DeadlineFormSet(self.data, instance=self.g) 
     self.assertEqual(formset.is_valid(), True) 

    def test_formset_is_invalid_if_additional_deadlines_earlier(self): 
     # formset should be invalid if any additional deadlines are earlier 
     # than the main deadline 
     self.g.deadline = date.today() 
     yesterday = date.today() - timedelta(days=1) 
     self.data['additional_deadlines-0-deadline'] = yesterday 
     formset = self.DeadlineFormSet(self.data, instance=self.g) 
     self.assertEqual(formset.is_valid(), False)
