我是Django的新手,所以请不要严厉地评价我。
我有自定义用户模型,我使用DRF创建用户个人资料。我将 create_user (BaseUserManager的方法)中的电子邮件规范化。我找不到如何规范API Serializer中电子邮件字段值的方法。基本上,如果我传递一个已经存在于数据库中的电子邮件,但只是在域中使用大写字母,它将通过序列化程序的验证,但是在它之后它会遇到完整性错误:
duplicate key value violates unique constraint "accounts_user_email_key"
DETAIL: Key (email)=(email@example.com) already exists.
以下是 UserManager 方法的简化版本:
class UserManager(BaseUserManager):
def create_user(self, email, first_name, last_name, password):
#some validation logic
#...
user = self.model(
email=self.normalize_email(email),
first_name=first_name,
last_name=last_name
)
user.set_password(password)
user.save()
return user
#other stuff...
这是序列化程序本身:
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = models.User
fields = ('email', 'first_name', 'last_name', 'password')
extra_kwargs = {k: {'write_only': True} for k in fields}
#some password validation...
def create(self, validated_data):
user = models.User.objects.create_user(
email=validated_data['email'],
first_name=validated_data['first_name'],
last_name=validated_data['last_name'],
password=validated_data['password']
)
return user
以下是视图:
class UserCreate(generics.CreateAPIView):
serializer_class = serializers.UserSerializer
答案 0 :(得分:1)
您可以在序列化程序中使用field-level-validation:
class UserSerializer(serializers.ModelSerializer):
class Meta:
model = models.User
fields = ('email', 'first_name', 'last_name', 'password')
extra_kwargs = {k: {'write_only': True} for k in fields}
def validate_email(self, value):
norm_email = value.lower()
if models.User.objects.fiter(email=norm_email).exists():
raise serializers.ValidationError("Not unique email")
return norm_email
