如何使用api创建PointField？ [英] How I can create a PointField using an api?

问题描述

我正在为API使用django-rest-framework，但是当我发出发布请求时，会向我发送此错误：

I am using django-rest-framework for the API, but when I make a post request sends me this error:

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

正文请求：

{
    "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()

我的序列化器是一个跟随者：

My serializer is a follow:

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

请帮助我！

推荐答案

我使用 PointField django-extra-fields 的$ c> 。对于前端开发人员来说超级好用且直观（我主要写移动后端）。这样，在序列化器中指定：

I use PointField from django-extra-fields for this. Supernice and intuitive for frontend developers (I write mobile backends mostly). With that, in your serializer specify:

from drf_extra_fields.geo_fields import PointField

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

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

请求（猜测您的哪个值是经纬度，哪个值是lon）：

Request (taking a guess as to which of your values is lat and which is lon):

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