在for循环中将参数传递给视图函数( form )以填充form flask wtforms sqlalchemy

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField
from wtforms.validators import DataRequired
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50), nullable=False)

class UserForm(FlaskForm):
    name = StringField('Name', validators=[DataRequired()])
    submit = SubmitField('Submit')

@app.route('/', methods=['GET', 'POST'])

        user = User(name=form.name.data)
        db.session.add(user)
        db.session.commit()
    users = User.query.all()
    for user in users:
        form.name.data = user.name
        # 在这里可以对表单进行其他操作，如修改字段值或添加额外的字段
    return render_template('index.html', form=form)
