Question

我想在我的django models.py中执行此导入：

from django.contrib.postgres.fields import ArrayField

我已阅读此文档https://docs.djangoproject.com/en/dev/ref/contrib/，我补充道 'django.contrib.postgres'进入settings.py中的INSTALLED_APPS，但是当我尝试同步我的db或runserver时，我得到了“ImportError：没有名为postgres的模块”

我还应该做些什么或安装吗？ django.contrib.postgres是核心发行权的一部分吗？

这是追溯：

Answer 1

django.contrib.postgres将成为1.8发布的一部分。

Answer 2

幸运的是，django中有几个非官方的postgresql数组实现。其中最值得注意的是djorm-pgarray。当Django 1.8最终推出时，另一个选择是django-dbarray，迁移不应该太困难。

如何使用PostgreSQL DB在Django中使用ArrayField？
