修改models效果如下
class EmAIlVerifyRecord(models.Model): code = models.CharField(max_length=20, verbose_name= u"验证码") email = models.EmailField(max_length=50, verbose_name=u"邮箱") send_type = models.CharField(choices=(("register",u"注册"),("forget",u"找回密码")), max_length=10 ,verbose_name=u"发送类型") send_Time = models.DateTimeField(default=datetime.now, verbose_name=u"添加时间") class Meta: verbose_name = u"邮箱验证码" verbose_name_plural = verbose_name #新增如下代码 def __str__(self): return '{0}({1})'.format(self.code ,self.email)
补充知识：django model 重载objects实现自定义控制
场景需求
班级model作为foriegnfield供用户选择，为了方便选择我们需要过滤掉一部分数据
解决方案 重载objects
class BanjiManager(models.Manager):
def get_queryset(self):
return super(BanjiManager, self).get_queryset().filter(DQSZJ='2016')
class StuBK_banji(models.Model):
#rid = models.IntegerField(_(u'序号'),primary_key=True)
FY = models.CharField(_(u'学院'),max_length=40)
BH = models.CharField(_(u'班级'),max_length=40, blank=True)
DQSZJ = models.CharField(_(u'年级'),max_length=40, blank=True)
objects = BanjiManager()
def __str__(self):
return self.FY+'_'+self.BH
class Meta:
verbose_name = u"班级（从教务处数据提取）"
verbose_name_plural = verbose_name
