Django模型表单 - 无效且没有任何错误

Question

我正在为Django表单编写测试。我正在使用初始数据填充它。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。

这里是代码。

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) 

目前的O/P是

(u'Instance Title', u'') 
(u'Valid: ', False) 
(u'Errors: ', {}) 
Destroying test database for alias 'default'... 

Process finished with exit code 1 

Error 
Traceback (most recent call last):

    cleaned_data = self.cleaned_data 
AttributeError: 'BlogPostKeywordCheck' object has no attribute 'cleaned_data' 

并且如果我不实例中明确添加USER_ID，它告诉我，USER_ID不能为空。如果我将其放入初始数据中，则不起作用。

您尚未将任何数据传递给表单，只有初始值。因此表单不受限制，不能有效。
