我正在使用 Django DRF 和 GeoDjango 构建一个简单的模型,如下所示。
class Company(models.Model):
name = models.CharField(max_length=200, default='Company', null=True)
def __unicode__(self):
return self.name
class Shop(models.Model):
name = models.CharField(max_length=200, default="bla")
address = models.CharField(max_length=300, default='blabla')
location = models.PointField(null=True, blank=True, geography=True)
company = models.ForeignKey(
Company, on_delete=models.CASCADE, null=True)
这是它的serializer.py
class ShopSerializer(serializers.ModelSerializer):
distance = serializers.DecimalField(
source='distance.km', max_digits=10, decimal_places=2, required=False, read_only=True)
class Meta:
model = Shop
fields = ['id', 'name', 'address', 'location', 'distance']
# read_only_fields = ['distance']
class CompanySerializer(serializers.ModelSerializer):
shop_set = ShopSerializer(many=True)
class Meta:
model = Company
fields = ['id', 'name', 'shop_set']
def create(self, validated_data):
shop_validated_data = validated_data.pop('shop_set')
company = Company.objects.create(**validated_data)
shop_set_serializer = self.fields['shop_set']
for each in shop_validated_data:
each['company'] = company
shops = shop_set_serializer.create(shop_validated_data)
return company
一切正常,直到我添加rest_framework_gis
我的 settings.py 文件或在我的商店序列化程序中添加以下行
serialize('geojson', Shop.objects.all(),
geometry_field='location', fields=('name', 'address'))
在这两种情况下都会出现 GDALException OGR 失败。我检查了我的 GDAL 和 Python 版本。两者都是 64 位的。python 和 GDAL 都运行良好。
我在这里基本上需要做的是将我的 POINT 字段转换为 json lat long 响应,现在响应就是这样(如果我不包括导致错误的行)。
{
"id": 1,
"name": "Cosmetica",
"address": "somwhere",
"location": "SRID=4326;POINT (24.896 67.182)"
}
请帮忙。
