GeoDjango：PostgreSQL未运行迁移，对象没有属性'geo_db_type [英] GeoDjango: PostgreSQL not running migrations, object has no attribute 'geo_db_type

问题描述

Django v1.11.5

Django v1.11.5

我正在尝试安装GeoDjango来与GoogleMaps一起玩。

I'm trying to install GeoDjango to play around with GoogleMaps.

我安装了用于MAC的PostgreSQL应用程序，并安装了 pip install psycopg2 。我还使用自制软件安装了GDAL。

I installed PostgreSQL app for MAC and installed pip install psycopg2. I also used home-brew to install GDAL.

编辑 settings.py 添加：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'djangodb',
        'USER': 'admin',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

但是，当我运行 python manage.py migration我得到： AttributeError：'DatabaseOperations'对象没有属性'geo_db_type'

However, when I run python manage.py migrate I get: AttributeError: 'DatabaseOperations' object has no attribute 'geo_db_type'

我使用以下方法创建了用户：创建数据库djangodb OWNER管理员;

I created the user using:CREATE DATABASE djangodb OWNER admin;

完全错误：

推荐答案

您需要更改数据库设置为使用postgis后端，

You need to change your DATABASES setting to use the postgis backend,

'ENGINE': 'django.contrib.gis.db.backends.postgis',

并添加'django.contrib.gis' ，到 INSTALLED_APPS 。
