Question

我想验证电子邮件ID，如果在注册前用户模型中已存在

这是我的验证序列化器

class RegistrationSerializer(serializers.Serializer):
    username = serializers.CharField(max_length=100)
    email = serializers.EmailField()
    password = serializers.CharField(max_length=100)

    def validate_email(self,attrs):
            email=attrs['email']
            print email
            if email:
                    emailset = Q(email__icontains=email)
                    emailres = User.objects.filter(emailset)
                    if emailres:
                            msg = _('The email address is already taken')
                            raise serializers.ValidationError(msg)
                    else:
                            return attars

抛出错误＆＃34; TypeError：字符串索引必须是整数＆＃34;

 email=attrs['email']

TypeError：字符串索引必须是整数

我猜你已升级或使用DRF 3.x，因此不再有attrs字典而是值。见field-level-validation

此外还有一个UniqueValidator。所以我认为你可以做到：

class RegistrationSerializer(serializers.Serializer):
    #...
    email = serializers.EmailField(validators=[UniqueValidator(queryset=User.objects.all())])
