Re: Custom serializers

[Xavier Ordoquy]

Hi,

if you want to flatten a related object, you’ll have to use the source argument to map the serializer fields to a related object fields.

The downside here is that you’ll have to list explicitly all the related fields which can be somewhat tedious.

      Hello, i have problem in custom serialization and i look in documentation for hours, but i couldn't figure out what i will do. 

 I have nested serializers object like below but i want to have non-nested object, can anyone help me about this? 

Nested Object: 

{

        "id": 1,

        "adDate": "20-08-2016",

        "price": "30.50",

        "city": "Istanbul",

        "latitude": "28.987509",

        "longitude": "41.040353",

        "isPublished": true,

        "book": {

            "id": 1,

            "bookName": "GameOfThrones",

            "category": "Adventure",

            "photo": "http://localhost:8000/media/advert_images/game_of_thrones.jpg",

            "description": "Adventure Book",

            "author": "Emre Yavuz",

            "language": "Sangridce",

            "publicationDate": "2023",

            "publisher": "Deu_Yapim",

            "edition": "22",

            "page_number": 900

        }

}

Non-Nested Object:

{

        "id": 1,

        "adDate": "20-08-2016",

        "price": "30.50",

        "city": "Istanbul",

        "latitude": "28.987509",

        "longitude": "41.040353",

        "isPublished": true,

        

        "id": 1,

        "bookName": "GameOfThrones",

        "category": "Adventure",

         "photo": "http://localhost:8000/media/advert_images/game_of_thrones.jpg",

         "description": "Adventure Book",

         "author": "Emre Yavuz",

        "language": "Sangridce",

        "publicationDate": "2023",

        "publisher": "Deu_Yapim",

         "edition": "22",

         "page_number": 900

       

}

MY Serializer Class: 

 class AdvertSerializer(serializers.ModelSerializer):

    book = BookSerializer()

    class Meta(object):

        model = Advert

        fields = ('id', 'adDate', 'price',"city","latitude","longitude","isPublished",'book','seller')

        depth = 2

class BookSerializer(serializers.ModelSerializer):

    photo = serializers.ImageField(max_length=None,use_url=True) 

    class Meta(object):

        model = Book
