Django ORM对象

我用的是Django ORM

当我打字的时候

从app.models导入天气

Weather.objects.all（）

它印刷了：

DEBUG 2017-06-11 09:43:44,051 utils 12912 384 (0.083) SELECT `weather`.`id`, `weather`.`time`, `weather`.`tpr`, `weather`.`wet`, `weather`.`uv` FROM `weather` LIMIT 21; args=()

[<Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather obj]

当我键入

print（Weather.objects.all（））

它印刷了：

DEBUG 2017-06-11 09:43:44,051 utils 12912 384 (0.083) SELECT `weather`.`id`, `weather`.`time`, `weather`.`tpr`, `weather`.`wet`, `weather`.`uv` FROM `weather` LIMIT 21; args=()

[<Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather object>, <Weather: Weather obj]

但结果并没有改变

接下来该怎么做？

为什么要定义4个unicode方法？如果您使用的是Python3，那么定义def__str__（self）：谢谢，我想我可以

def__str__（self）：返回self.tpr、self.wet、self.uv、self.li

def __str__(self): 
    return "{0} {1} {2} {3}".format(self.tpr, self.wet, self.ur, self.li)
