多嵌套Django Restframework和Mongodb

问题描述

我想要这样的输出。我的任务是使用RestFawork完成5种以上的嵌套类型模型和所有CRUD方法。如果有人知道与我分享答案的话。

{
    "id": 1,"first_name": "John 1","last_name": "Robert 1","instrument": "KeyBoard","album_musician": [
        {
            "id": 3,"artist": 1,"name": "Test robert","release_date": "2020-09-16","num_stars": 400
             "Language": [
                  {
                   
                     
                     "Original": "English","dubbed": "Tamil"
           
                 }

    ]
        }
        
    ]
}

在此代码中，我仅执行了Sigle嵌套框架。 我的模型。py

Serializer.py 在此序列化中，我使用了CRUD方法

class AlbumSerializer(serializers.ModelSerializer):

    class Meta:
        model = Album
        fields = ('id','artist','name','release_date','num_stars')


class MusicianSerializer(serializers.ModelSerializer):
    album_musician = AlbumSerializer(many=True)

    class Meta:
        model = Musician
        fields = ('id','first_name','last_name','instrument','album_musician')
        lookup_field=id

    def create(self,validated_data):
        albums_data = validated_data.pop('album_musician')
        musician = Musician.objects.create(**validated_data)
        for album_data in albums_data:
            Album.objects.create(artist=musician,**album_data)
        return musician

    def update(self,instance,validated_data):
        albums_data = validated_data.pop('album_musician')
        albums = (instance.album_musician).all()
        albums = list(albums)
        instance.first_name = validated_data.get('first_name',instance.first_name)
        instance.last_name = validated_data.get('last_name',instance.last_name)
        instance.instrument = validated_data.get('instrument',instance.instrument)
        instance.save()

        for album_data in albums_data:
            album = albums.pop(0)
            album.name = album_data.get('name',album.name)
            album.release_date = album_data.get('release_date',album.release_date)
            album.num_stars = album_data.get('num_stars',album.num_stars)
            album.save()
        return instance
