[django]用日期来查询datetime类型字段

有一个model的字段是 DateTimeField,我现在要具体查询某一天date的数据，应该怎么用orm来查询呢？

指定年月日

YourModel.objects.filter(datetime_published__year='2008', 
                         datetime_published__month='03', 
                         datetime_published__day='27')
   
   
  
  

  
  
 
 

字符串匹配

YourModel.objects.filter(your_datetime_field__startswith=datetime.date(2009,8,22))
   
   
  
  

  
  
 
 

字符串包含

Mymodel.objects.filter(date_time_field__contains=datetime.date(1986, 7, 28))
