GeoDjango：PostgreSQL 不是 运行 迁移，对象没有属性 'geo_db_type

Question

Django v1.11.5

我正在尝试安装 GeoDjango 以使用 GoogleMaps。

我为 MAC 安装了 PostgreSQL 应用程序并安装了 pip install psycopg2。我还使用自制软件安装 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 迁移时，我得到：AttributeError: 'DatabaseOperations' object has no attribute 'geo_db_type'

我创建用户使用：CREATE DATABASE djangodb OWNER admin;

完整错误：

我试过的类似问题： Getting 'DatabaseOperations' object has no attribute 'geo_db_type' error when doing a syncdb

Answer 1

您需要更改 DATABASES 设置以使用 postgis 后端，

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

并将 'django.contrib.gis' 添加到 INSTALLED_APPS。
