我正在尝试使用 Django 项目中的地理位置来保存商店。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出现异常。
在我的 django 应用程序（商店）中，我有以下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)
从管理 UI 我可以创建商店，但是当我尝试打开任何商店以查看保存的数据时，我看到以下异常

但是当我更改我的admin.py时，我看到了地图，但视图很丑
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)
