当我尝试：

the django cast the following error :

django投下以下错误：

AttributeError at /tag_study/my_infor/ type object 'StudyRecord' has no attribute 'object'

/ tag_study / my_infor / type对象'StudyRecord'中的AttributeError没有属性'object'

Traceback Switch to copy-and-paste view

回溯切换到复制粘贴视图

    C:\Python27\lib\site-packages\django-1.7.3py2.7.egg\django\core\handlers\base.py in get_responseresponse = wrapped_callback(request, *callback_args, **callback_kwargs) ...
   ▶ Local vars
   c:\mystudio\tag_study\views.py in my_inforurrent_book = StudyRecord.object.filter(user__name__contains= id ) ...
   ▶ Local vars

the StudyRecord models:

StudyRecord模型：

    class StudyRecord(models.Model):
             user = models.ForeignKey(User)
             book = models.CharField(max_length=128)
             starttime= models.DateTimeField()
             endtime = models.DateTimeField()
        def save(self, *args, **kwargs):
             self.slug = slugify(self.number)
             super(StudyRecord, self).save(*args, **kwargs)

        def __unicode__(self):      #For Python 2, use __str__ on Python 3
             return self.book

and this is the views

这是意见

    def my_infor(request):
        if request.method == "GET":
            if request.user.is_authenticated():
               id = request.user.id
                StudyRecord.object.filter(user__name__contains= id )
                return HttpResponse(current_book)
        else:
            return HttpResponse("error2")
        context = RequestContext(request)
        return render_to_response('tag_study/my_infor.html', context)

2 个解决方案

#1

It should be objects, not object

它应该是对象，而不是对象

#2

When you get data from db, you need a Manager through which you can construct the QuerySet you wanted.

从db获取数据时，需要一个Manager，您可以通过它来构造所需的QuerySet。

Each model has at least one Manager, and it’s called objects by default.

每个模型至少有一个Manager，默认情况下称为对象。
