django 读取mysql某个字段_django获取指定列的数据

django获取指定列的数据

model一般都是有多个属性的，但是很多时候我们又只需要查询特定的某一个，这个时候可以用到values和values_list

[values()](https://docs.djangoproject.com/en/1.9/ref/models/querysets/#values)

values()¶

values(*fields)¶

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

Each of those dictionaries represents an object, with the keys corresponding to the attribute names of model objects.

[values_list()](https://docs.djangoproject.com/en/1.9/ref/models/querysets/#values-list)

values_list()¶

values_list(*fields, flat=False)¶

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over. Each tuple contains the value from the respective field passed into the values_list() call — so the first item is the first field, etc.

看下面的代码：

利用values查询
