Python迭代未捕获WTForms数据字段/字段列表中的所有数据

from flask import Flask, request
from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField

class MyForm(FlaskForm):
    field1 = StringField('Field 1')
    field2 = StringField('Field 2')
    submit = SubmitField('Submit')

@app.route('/form', methods=['GET', 'POST'])
def form():
    form = MyForm()
    if form.validate_on_submit():
        # 表单提交后的处理逻辑
        return 'Form submitted successfully!'
    return render_template('form.html', form=form)

<form method="POST" action="{{ url_for('form') }}">
  {{ form.hidden_tag() }}
  {% for field in form %}
    <div class="form-group">
      {{ field.label }}
      {{ field() }}
    </div>
  {% endfor %}
  <button type="submit" class="btn btn-primary">Submit</button>
