django - 如何使用 api 创建 PointField？

Question

我正在为 API 使用 django-rest-framework，但是当我发出 post 请求时向我发送此错误:

{
    "location": [
        "Invalid format: string or unicode input unrecognized as GeoJSON, WKT EWKT or HEXEWKB."
    ]
}

body 要求:

{
    "location":{
        "type":"Point",
        "coordinates":[37.0625,-95.677068]
    }
}

我的模型如下:

class Address(models.Model):
    location = geo.PointField(srid=4326, blank=True)
    objects = geo.GeoManager()

我的序列化程序如下:

class AddressCreateSerializer(serializers.ModelSerializer):
    class Meta:
        model = Address
        fields = ('location')

请帮帮我!

我用 PointField 来自 django-extra-fields为了这。对于前端开发人员来说非常直观(我主要编写移动后端)。这样，在您的序列化程序中指定:

from drf_extra_fields.geo_fields import PointField

class AddressCreateSerializer(serializers.ModelSerializer):
    location = PointField()

    class Meta:
        model = Address
        fields = ('location')

请求(猜测您的哪个值是 lat，哪个是 lon):

{
    "location":{
        "latitude": 37.0625
        "longitude": -95.677068,
    }
}
