我正在设法挽救商店的地理位置在Django项目。而且我能够从管理UI中保存数据，但是当我访问保存的数据时会得到异常。

在我的django应用程序(商店)中，我跟踪了models.py

代码语言：javascript
复制
from django.contrib.gis.db import models

class Shop(models.Model):
    name = models.CharField(max_length=100)
    location = models.PointField()
    address = models.CharField(max_length=100)
    city = models.CharField(max_length=50)

我安装了django传单settings.py

代码语言：javascript
复制
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.gis',
    'leaflet',
    'shops'
]

admin.py看起来像这样

代码语言：javascript
复制
#from django.contrib import admin
from django.contrib.gis import admin
from .models import Shop
from leaflet.admin import LeafletGeoAdmin


class ShopAdmin(LeafletGeoAdmin):
    list_display = ('name', 'location')

admin.site.register(Shop, ShopAdmin)

在管理UI中，我可以创建商店，但是当我试图打开任何商店来查看保存的数据时，我会看到以下异常

Exception Type: GDALException at /admin/shops/shop/16/change/
Exception Value: OGR failure.

但是当我改变我的admin.py时，我看到的是地图，但却是丑陋的视图。

代码语言：javascript
复制
from django.contrib.gis import admin
from .models import Shop
from leaflet.admin import LeafletGeoAdmin

class ShopAdmin(admin.GeoModelAdmin):
    list_display = ('name', 'location')

admin.site.register(Shop, ShopAdmin)

我也有类似的问题。检查您的GDAL版本

代码语言：javascript
复制
gdalinfo --version
GDAL 3.0.4, released 2020/01/28

对GDAL3.x的支持刚刚添加到django，但截至2020年5月13日还没有发布：看这儿

很可能，如果您只是为了测试目的(!)切换lat和长输入到GEOSGeometry，它将再次工作。AxisOrder和AxisMappingStrategy是上述修复程序中的新内容。
