基本的数据访问   直接上代码吧  比较简单的操作。

>>> from book.models import Publisher>>> p1 = Publisher(name='Apress', address='2855 Telegraph Avenue',city='Berkeley', state_province='CA', country='U.S.A.',website='http://www.apress.com/')>>> p1.save()>>> p2 = Publisher(name="O'Reilly", address='10 Fawcett St.',city='Cambridge', state_province='MA', country='U.S.A.',website='http://www.oreilly.com/')>>> p2.save()>>> publisher_list = Publisher.objects.all()>>> publisher_list
     
      , 
      
       ]>>>> type(publisher_list)
       
        >>> for i in publisher_list:...     i... 
        
         
          >>> for i in publisher_list:...     i.name... 'Apress'"O'Reilly">>> Publisher.objects.create(name="O'Yuqn", address='11 Fawcett St.',city='Cambridge', state_province='MA', country='U.S.A.',website='http://www.oreilly.com/')
          
           >>> Publisher.objects.create(name="O'Y11uqn", address='11 Fa11wcett St.',city='11Cambridge', state_province='11MA', country='U.111S.A.',website='http://www.orei11lly.com/')
           
            >>> publisher_list = Publisher.objects.all()>>> for i in publisher_list:... i.name... 'Apress'"O'Reilly""O'Yuqn""O'Y11uqn"
           
          
         
        
       
      
     

如果我们要删除对象的话，删除数据库中的对象只需调用该对象的delete()方法即可：

>>> p = Publisher.objects.get(name="O'Reilly")>>> p.delete()>>> Publisher.objects.filter(country='USA').delete()>>> Publisher.objects.all().delete()

更新对象，很简单，先获取对象然后将其当做一般的变量进行赋值即可。当然还是要保存的。

>>> p.name = 'Apress Publishing'>>> p.save()
