How to serialize file without host?-CodePudding

I am working on my Django (DRF) app.

I have a user avatar

class CustomUser(AbstractBaseUser, PermissionsMixin):
    avatar = models.ImageField(upload_to='avatars/', blank=True)
    ...

I want to serialize avatar field:

class CustomUserSerializer(serializers.ModelSerializer):
    avatar = serializers.FileField(use_url=False, required=False)

    class Meta:
        model = CustomUser
        fields = [
            'avatar',
            ...
        ]

Current result is "avatar": "avatars/ZZZ.png"

How can I get "avatar": "media/avatars/ZZZ.png" ??? (what is the proper way)

Saved file location is http://localhost:6060/media/avatars/<file_name>.png

I haven't worked with image field serialized. Below is my solution, and don't know if there is a better way. You can override the to_representation method of your serializer to achieve it as shown below.

class CustomUserSerializer(serializers.ModelSerializer):
    avatar = serializers.FileField(use_url=False, required=False)

    class Meta:
        model = CustomUser
        fields = [
            'avatar',
            ...
        ]

    def to_representation(self, instance):
         resp = super().to_representation(instance)
         resp['avatar'] = f'media/{resp["avatar"}'
         return resp
