功能模块分为两大块，分别为简易用户及用户组管理模块以及枪杀模块。
urls设计
/ 首页
/admin 自带用户管理页面
/ctr 用户组管理
/api-auth api认证
/seckill/list 显示所有枪杀商品信息
/seckill/(?P<pk>[0-9]+)/detail 显示某个枪杀商品详细信息
/seckill/time/now 显示当前信息
/seckill/(?P<pk>[0-9]+)/url 暴露抢杀的url
/seckill/setphone 设置电话
/seckill/kill 抢杀
model层
用户管理模块的模型为框架本身所有，抢杀模块的模型包括商品信息，抢杀记录，抢杀地址暴露模型。
seckill/models.py
商品信息
class Seckill(models.Model):
seckill_id = models.BigIntegerField(primary_key=True)
name = models.CharField(max_length=120)
number = models.IntegerField()
start_time = models.DateTimeField()
end_time = models.DateTimeField()
create_time = models.DateTimeField()
def __unicode__(self):
return self.name
class Meta:
managed = True
db_table = 'seckill'.
抢杀记录
class SuccessKilled(models.Model):
id = models.BigIntegerField(primary_key=True)
seckill_id = models.BigIntegerField()
user_phone = models.BigIntegerField()
state = models.IntegerField()
create_time = models.DateTimeField()
class Meta:
managed = True
db_table = 'success_killed'
暴露url
#商品不存在时
class Exposed(models.Model):
exposed=models.BooleanField()
seckill_id=models.BigIntegerField()
#抢杀未开放时
class ExposedNoOpen(Exposed):
now = models.DateTimeField()
start = models.DateTimeField()
end = models.DateTimeField()
#可抢杀
class ExposedOpen(Exposed):
md5= models.CharField(max_length=100)
序列化
userAdmin\serializers.py
对User以及Group进行序列化
#对User进行序列化
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model=User
fields=('url','username','email','groups')
#对Group进行序列化
class GroupSerializers(serializers.HyperlinkedModelSerializer):
class Meta:
model=Group
fields=('url','name')
seckill\serializers.py
对抢杀模型进行序列化
# 抢杀商品的序列化
class SeckillSerializer(serializers.ModelSerializer):
class Meta:
model=Seckill
fields=('seckill_id','name','number','start_time','end_time','create_time')
class SuccessKilledSerializer(serializers.ModelSerializer):
class Meta:
model = SuccessKilled
fields = ('seckill_id', 'user_phone', 'state', 'create_time')
class ExposedNoIdSerializer(serializers.ModelSerializer):
class Meta:
model = Exposed
fields = ('exposed', 'seckill_id')
class ExposedNoOpenSerializer(serializers.ModelSerializer):
class Meta:
model = ExposedNoOpen
fields = ('exposed', 'seckill_id', 'now', 'start','end')
class ExposedOpenSerializer(serializers.ModelSerializer):
class Meta:
model = ExposedOpen
fields = ('exposed', 'seckill_id', 'md5')
视图的实现
用户管理的视图

#组的输出
