使用memocache

直接cmd下运行 pip3 install python-memcached

serializer.py 里的特别应用

如果一个表模型一些字段用到了跨表。可以这样取值

跨表字段 coach_nickname = serializers.CharField(source='coachinfo.nickname')

可以获取多个选项的字段：sort = serializers.CharField(source='get_course_type_display')

class Meta:

model = models.Course

fields = ['id','name','sort','coach_nickname']

manytomany 反向查找型：

price_policy = serializers.SerializerMethod()

def get_policy_policy(self,obj):

price_policy_list = price_list.objects.all()

return [{'id':row.id,'itemname':row.itemname} for row in price_policy_list]
