修改models效果如下
class EmailVerifyRecord(models.Model): code = models.CharField(max_length=20, verbose_name= u"驗證碼") email = models.EmailField(max_length=50, verbose_name=u"郵箱") send_type = models.CharField(choices=(("register",u"註冊"),("forget",u"找回密碼")), max_length=10 ,verbose_name=u"發送類型") send_Time = models.DateTimeField(default=datetime.now, verbose_name=u"添加時間") class Meta: verbose_name = u"郵箱驗證碼" verbose_name_plural = verbose_name #新增如下代碼 def __str__(self): return '{0}({1})'.format(self.code ,self.email)
補充知識：django model 重載objects實現自定義控制
場景需求
班級model作為foriegnfield供用戶選擇，為了方便選擇我們需要過濾掉一部分數據
解決方案 重載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'序號'),primary_key=True) FY = models.CharField(_(u'學院'),max_length=40) BH = models.CharField(_(u'班級'),max_length=40, blank=True) DQSZJ = models.CharField(_(u'年級'),max_length=40, blank=True) objects = BanjiManager() def __str__(self): return self.FY+'_'+self.BH class Meta: verbose_name = u"班級（從教務處數據提取）" verbose_name_plural = verbose_name
