PointField()在GeoDjango中无法正常工作

标签: django geodjango

我安装了GDAL(使用homebrew)和SQLite。我想创建一个带有PointField()的老师,它存储long和lat值,以了解它们的位置。后来我计划使用类似的东西添加按距离搜索的功能:

Teacher.objects.filter(location__distance_lte=(your_location,D(m=distance))).distance(your_location).order_by('distance')

models.py

from django.db import models
from django.contrib.gis.db import models as gis_models
from django.contrib.auth.models import User

class Teacher(models.Model):
    user = models.ForeignKey(User, unique=True)
    location = gis_models.PointField()
    availability = models.BooleanField(default=False)

但是,当我运行服务器时,出现以下错误:

这是一个已知问题,已修复并将在Django v1.11.5中推出。

如果您不能等待1.11.5或者不想在开发分支上运行,您可以转到以前版本的地理位置:

brew switch geos 3.6.1
