python之Django 模型表单之没有任何错误无效

我正在为 Django 表单编写测试。我正在用初始数据填充它。但是，当我保存表单时，出现错误，指出它没有 cleaned_data 属性。

这可能是因为表单未通过验证但也未显示任何错误。

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

而且，如果我没有在实例中显式添加 user_id，它会告诉我 User_id 不能为 null。如果我将它放在初始数据中，则不起作用。

请您参考如下方法:

您还没有向表单传递任何数据，只有初始值。因此该表格未绑定(bind)且无效。
