任务是:如何将所有三个模型链接为我的要求。
要求:如果用户转介给某人(other User)
,他的amount
会收到一些wallet (Referral Based)
。一个user
可以refer
到多个user
。
正如我上面提到的要求标准......请完整需要
我必须创建下面提到的三个模型,这些模型与User
模型相关联。
1. Wallet
2. Wallet_Log
3. Referral
参见创建需要建议的模型..
class Wallet(models.Model):
owner = models.OneToOneField(user, related_name='wallet', unique=True)
amount = models.FloatField(default=0.0)
datetime = models.DateTimeField(auto_now_add=True,null=True)
walletID = models.CharField(max_length=10, default="00000")
ack = models.BooleanField(default=False)
def __unicode__(self):
return u'%s' % self.owner
@property
def set_ack(self):
return self.ack
@set_ack.setter
def set_ack(self, bol):
self.ack = bol
class WalletLog(models.Model):
wallet = models.ForeignKey(Wallet)
user_from = models.ForeignKey(user, null=True, blank=True)
amount = models.FloatField()
datetime = models.DateTimeField(auto_now_add=True, null=True)
report = models.CharField(max_length=100)
def get_wallet_log(self):
if(self.wallet):
return "%s"%(self.wallet.amount)
else:
return "Not Available"
def get_user_from_log(self):
if(self.user_from):
return "%s"%(self.user_from.user_first_name)
else:
return "Not Available"
def __unicode__(self):
return u'%s' % self.wallet
class OrderReferral(models.Model):
referrer = models.ForeignKey(user, related_name='referrer')
referred = models.ForeignKey(user, related_name='referred')
wallet = models.ForeignKey(Wallet, related_name='order_referred')
created_date = models.DateTimeField()
updated_date = models.DateTimeField()
order_active = models.BooleanField()
def __unicode__(self):
return '%s %s made a referral' % (self.referrer.first_name, self.referrer.last_name)
class Meta:
verbose_name_plural = "Order Referral"
答案 0 :(得分:1)
是最后通过撰写model relationship
和join query
,以正确的方式设置test case
以避免不必要的code
。
