Serializing multiple models

[Lucas Simon]

Does the model serializer support serialization of multiple models? I want to have a UserProfile model that stores additional information and have a single endpoint for creating a new user and user profile. Let's say that my model

class UserProfile(models.Model):

    user = models.OneToOneField(User)

    bio = models.TextField()

    age = models.IntegerField()

Is there a feature that supports something like this?

class NewUserSerializer(serializers.ModelSerializer)

    class Meta:

        model = User and UserProfile

You can specify serializers to user for model relationships.

class UserProfileSerializer(serializers.ModelSerializer):

    class Meta:

        model = UserProfile

        fields = ('photo')

class UserSerializer(serializers.ModelSerializer):

    profile = UserProfileSerializer()

    class Meta:

        model = User

        fields = ('id', 'email', 'profile', 'username')

But in that case you'll have a nested response such as:

{"username": xxx ,

"email": xxxx,

"profile": {"birthday": xxxx,"photo":xxx}

"..."

}

what about to get the response without nested:

{

"username": xxx

"email": xxx

"birthday":xxxx

"photo": xxxx

}

I will appreciate that!

Since you don't care about the data hierarchy and just need a flat format, I assume this implies you don't use the same serializer for deserialization. If that's true, you should use Serializer instead of ModelSerializer. Below is an example.

Assume you have a UserProfile model, which has one-to-one relationship to the django User model, defined. The serializer you use defines how your data looks like (see below)

from rest_framework import serializers

from rest_framework.fields import Field

class UserSerializer(serializers.Serializer):

    username = Field(source='username')

    email = Field(source='email')

    birthday = Field(source='userprofile.birthday')

    photo = Field(source='userprofile.photo.url')

And then as for the corresponding view:

from rest_framework.views import APIView

from rest_framework.response import Response

class LoadUserView(APIView):

    def get(self, request, format=None):

        user = self.request.user

        serializer = InitMyAccountSerializer(user)

        return Response(serializer.data)

With the serializer and the view about, you should get:

{

"username": xxx

"email": xxx

"birthday":xxxx

"photo": xxxx

}
