GeoDjango: PostgreSQL not running migrations, object has no attribute 'geo_db_type

问题

Django v1.11.5

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

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

Edited settings.py to add:

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

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

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

Full Error:

回答1:

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

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

and add 'django.contrib.gis', to INSTALLED_APPS.
