如何使用复选框通过嵌套表单修改模型中每个对象的值

# 前端页面示例
<form action="/update_model" method="POST">
  <input type="checkbox" name="objects[0].value" value="1"> Object 1<br>
  <input type="checkbox" name="objects[1].value" value="2"> Object 2<br>
  <input type="checkbox" name="objects[2].value" value="3"> Object 3<br>
  <input type="submit" value="Submit">
</form>

# 后端处理示例（使用Python和Flask框架）
from flask import Flask, request

app = Flask(__name__)

@app.route('/update_model', methods=['POST'])
def update_model():
    objects = request.form.getlist('objects')
    for obj in objects:
        value = request.form.get(f'objects[{obj}].value')
        # 根据复选框的选择状态，修改模型中对象的值
        # ...

    # 更新模型中的值
    # ...

    return 'Model updated successfully'

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