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

Django v1.11.5

我正在尝试安装GeoDjango来玩GoogleMaps.

我为MAC安装了PostgreSQL应用程序并安装了pip install psycopg2.我还用home-brew来安装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'

我创建了用户:CREATE DATABASE djangodb OWNER admin;

完全错误:

GeoDjango：无法使用 PointField() 保存模型，错误：SpatialProxy (POINT) 的值类型为：<class 'users.models.Point'>

这个想法是集成谷歌地图而不是 GeoDjango v1.11.5 的默认地图PointField()。

目前，在我的models.py 中

class Teacher(models.Model):
    user = models.OneToOneField(User, on_delete=models.PROTECT, related_name='Teacher')
    placename = models.CharField(blank=True,max_length=255)
    latitude = models.FloatField(blank=True, null=True, verbose_name='Latitude')
    longitude = models.FloatField(blank=True, null=True, verbose_name='Longitude')
    location = models.PointField(blank = True, null=True, srid=4326)
    objects = models.GeoManager()

    def save(self, *args, **kwargs):
        self.location = Point(self.longitude, self.latitude)
        super(Teacher, self).save(*args, **kwargs)  # Call the "real" save() method.

但是，当我在手动添加 long 和 lat 后单击保存时，我得到：
