Question

我正在为Django表单编写测试。我用初始数据填充它。但是当我保存表单时，我得到的错误是它没有clean_data属性。

可能会发生这种情况，因为表单没有验证，但也没有显示任何错误。

这是代码。

def test_keyw(self):
    class BlogPostKeywordCheck(forms.ModelForm):
        class Meta:
            model = BlogPost
            exclude = ()

    data = {'keywords': 'awwww,aaa,lol'}


    initial_data = {
        "title":"Test Keywords",
        "content":"<p>Testing Keywords</p>",
        "status":CONTENT_STATUS_PUBLISHED,
        "keywords":"call,me,abc",
        "user":self._user,
        "allow_comments":"on",
        "gen_description":"on",
        "in_sitemap":"on",
        "_save":"Save"
    }

    print (self._user)
    submitted_form = BlogPostKeywordCheck(initial=initial_data)

    print (submitted_form.fields)

    submitted_form.instance.user = self._user
    print("Instance Title",submitted_form.instance.title)


    print("Valid: ",submitted_form.is_valid())

    print ("Errors: ",submitted_form.errors)
    submitted_form.save()

    print (Keyword.objects.all())
    self.assertTrue(submitted_form.is_valid())
    print (submitted_form.errors)

目前O / P是

如果我没有在实例中显式添加user_id，它告诉我User_id不能为null。如果我把它放在初始数据中不起作用。

您尚未将任何数据传递给表单，只传递初始值。因此，表格不受约束，无效。

Django模型表单 - 没有任何错误无效
