在烧瓶中使用 WTFORMS 和 SQAlchemy 更新值

Question

我有一个网站。我想让人们只需在表格中输入即可轻松更新那里的电子邮件地址。这是我当前的尝试代码，但我尝试的一切都行不通。我已经有一个名为 email 的电子邮件专栏。

@app.route('/dashboard/settings', methods=['GET', 'POST'])
@login_required
def settings():
    form = EmailForm()
    if form.validate_on_submit():
        current_user.email = form.email.data
        session.commit()
        return redirect("dashboard/settings")
    return render_template("settings.html", form=form)

这些是我的插件

from flask import Flask, render_template, session, abort, redirect, url_for
from flask_sqlalchemy import SQLAlchemy
from flask_login import UserMixin, login_user, LoginManager, login_required, logout_user, current_user
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import InputRequired, Length, ValidationError
from flask_bcrypt import Bcrypt
from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView  
from flask_security import roles_required

问题是我找不到要替换的用户信息。我做了一个查询来找到当前用户行，然后我将电子邮件编辑为表单收到的数据。

def settings():
form = EmailForm()
if form.is_submitted():
    user = User.query.filter_by(username=current_user.username).first()
    user.email = form.email.data
    db.session.commit()
    return redirect("/dashboard/settings")
return render_template("settings.html", form=form)
