django-rest-auth: how to get user info after successful authentication?

Question

The django-rest-auth returns a token after successful authentication using rest_auth.serializers.TokenSerializer. How can I override this serializer or add my own so that I can get the user info like username, instead of token key after successful authentication?

Answer 1

I solved the problem by defining a custom serializer.

from django.contrib.auth.models import User
from rest_framework import serializers
from rest_auth.models import TokenModel

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('username', 'email')

class TokenSerializer(serializers.ModelSerializer):
    user = UserSerializer()
    class Meta:
        model = TokenModel
        fields = ('key', 'user')

You can also use the depth option to easily generate nested representations, but in that case, you will receive the password field as well, which is not expected and intended.
