如何从 StringField 中拆分数据

Question

我有注册表单，用户可以在其中输入他们的名字、姓氏、电子邮件和密码。我正在尝试获取该电子邮件并将其拆分以获取域并检查我的数据库是否该电子邮件已注册，但我无法拆分数据，无论我更改什么我都会不断收到不同的错误。

forms.py

class RegistrationForm(FlaskForm):
    first_name = StringField(
        "First Name", validators=[DataRequired(), Length(min=2, max=20)]
    )
    last_name = StringField(
        "Last Name", validators=[DataRequired(), Length(min=2, max=20)]
    )
    email = StringField("Email", validators=[DataRequired(), Email()])
    password = PasswordField("Password", validators=[DataRequired()])
    confirm_password = PasswordField(
        "Confirm Password", validators=[DataRequired(), EqualTo("password")]
    )
    submit = SubmitField("Sign Up")

    # Here i'm trying to split the email so I can use the domain.
    domain = email.split("@")[1]

    def validate_email(self, email, domain):
        user_email = User.query.filter_by(email=email.data).first()
        org_domain = Organization.query.filter_by(domain=domain.data).first()
        if user_email:
            raise ValidationError("That email is taken. Please choose a different one.")
        elif org_domain:
            raise ValidationError(
                "Your domain is managed by someone else, please contact your administrator. If you need help please contact our support"
            )

routes.py

@users.route("/register", methods=["GET", "POST"])
def register():
    if current_user.is_authenticated:
        return redirect(url_for("main.dashboard"))
    form = RegistrationForm()
    if form.validate_on_submit():
        hashed_password = bcrypt.generate_password_hash(form.password.data).decode(
            "utf-8"
        )

        organization = Organization(
            domain=form.email.data.split("@")[1],
        )
        db.session.add(organization)
        db.session.commit()
        admin = User(
            first_name=form.first_name.data,
            last_name=form.last_name.data,
            display_name=form.first_name.data + " " + form.last_name.data,
            email=form.email.data,
            password=hashed_password,
            org_id=organization.id,
        )
        db.session.add(admin)
        db.session.commit()
        flash("Your account has been created! You are now able to log in", "success")
        return redirect(url_for("users.login"))
    return render_template("users/register.html", title="Register", form=form)

我通过将其拆分为 def validate_email(self, email):

    domain = str(email).split("@")[1]
    domain = domain.split('"')[0]
