Django3.0：访问模型表单时GDALException

问题描述 投票：0回答：1

我正在尝试用Django项目中的地理位置来保存商店。而且我能够从管理界面保存数据，但是访问保存的数据时出现异常。

在我的django应用（商店）中，我关注了models.py

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)

我已经安装了django-leaflet settings.py

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

#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)

可以通过管理界面创建商店，但是当我尝试打开任何商店以查看保存的数据时，都会看到以下异常

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

但是当我用下面的方法更改我的admin.py时，我看到了地图，但视图很丑陋

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)

我有类似的问题。使用

检查您的GDAL版本
gdalinfo --version
GDAL 3.0.4, released 2020/01/28

对GDAL 3.x的支持刚刚被添加到django中，但是截至2020年5月13日尚未发布：look here

[如果仅出于测试目的（！），将lat和long输入输入到GEOSGeometry，它将再次起作用。 AxisOrder和AxisMappingStrategy是上述修订中的新内容。
