有没有一种方法可以在Django的属性实例中存储元组? [英] Is there a way to store a tuple in an attribute instance in Django?

问题描述

我想知道是否可以在Django的属性实例中存储元组吗?

I am wondering if it is possible to store a tuple in a attribute instance in Django?

类似的东西:

class MyModel(models.Model):

    my_tuple_field = TupleField()

，然后创建MyModel的实例，如下所示:

and then create an instance of MyModel as follow:

an_instance = MyModel.objects.create(my_tuple_field=('foo', 'bar'))

谢谢

推荐答案

为

As @p14z suggests, the best way to save my tuple was the ArrayField. For my example, I just wanted to save a Polygon extent, with this format:

(3.7739613717694787，50.31527681737183，4.726162032377，50.49743217278623)

from django.contrib.postgres.fields import ArrayField
my_tuple_field = ArrayField(models.FloatField(), size=4, null=True)
