DRF：图像与字段命名

Question

On my model, I have fields like photo = models.ImageField() – practically this means I can upload and set images from the admin; but from the DRF Serializer it feels more appropriate to suffix URL: photo_url = serializers.ImageField()

Is there a standard way of doing this in a DRF-y way here? I could of course make the photo on my model into photo_url , but that feels a bit strange.

You can do it in serializer validate method. For example:

class YourSerializer(serializers.ModelSerializer):
    photo_url = serializers.ImageField()

    class Meta:
        model = YourModel
        fields = [] #your model fields

    def validate(self,attrs):
        attrs['photo'] = attrs['photo_url']
        return attrs
