如何在modelform中显示flask外键字段的可读性显示下拉列表？

pip install flask-wtf wtforms

from flask_wtf import FlaskForm
from wtforms import QuerySelectField
from your_app.models import ForeignModel  # 导入外键模型

class MyForm(FlaskForm):
    foreign_field = QuerySelectField('Foreign Field', query_factory=lambda: ForeignModel.query, get_label='name')

from flask import render_template
from your_app.forms import MyForm

@app.route('/create', methods=['GET', 'POST'])
def create():
    form = MyForm()
    if form.validate_on_submit():
        # 处理表单提交逻辑
        pass
    return render_template('create.html', form=form)

<form method="POST">
    {{ form.hidden_tag() }}
    {{ form.foreign_field.label }} {{ form.foreign_field }}
    <button type="submit">Submit</button>
</form>
