User Account Details in Django Extended UserModel Serializer

There are instances where you want to get the information from django user model to the extended profile serializer. Django doesn't not come with a ready to use solution but its not hard to make one.

class UserAccountSerializer(serializers.ModelSerializer):
  id = serializers.IntegerField(source = 'pk', read_only = True)
  username = serializers.CharField(source = 'user.username', read_only = True)
  email = serializers.CharField(source = 'user.email')
  first_name = serializers.CharField(source = 'user.first_name')
  last_name = serializers.CharField(source = 'user.last_name')

It works by defining a field in serializer and using the source from user object of logged in user.
