RadioField / WTForms:实现动态Flask的正确方法

from flask_wtf import FlaskForm
from wtforms import RadioField

class MyForm(FlaskForm):
    radio_field = RadioField('Label', choices=[('option1', 'Option 1'), ('option2', 'Option 2')])

from flask import Flask, render_template

app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'

@app.route('/', methods=['GET', 'POST'])
def index():
    form = MyForm()
    if form.validate_on_submit():
        # 处理表单提交
        selected_option = form.radio_field.data
        # 其他逻辑
    return render_template('index.html', form=form)

if __name__ == '__main__':
    app.run()

<form method="POST" action="/">
    {{ form.csrf_token }}
    {{ form.radio_field.label }}
    {% for subfield in form.radio_field %}
        {{ subfield }}
        {{ subfield.label }}
    {% endfor %}
    <input type="submit" value="Submit">
</form>
