如何在flask-admin面板中添加你自己的装饰器？

def custom_decorator(func):
    def wrapper(*args, **kwargs):
        # 在函数执行之前执行的逻辑
        print("Custom decorator logic before function execution")
        result = func(*args, **kwargs)
        # 在函数执行之后执行的逻辑
        print("Custom decorator logic after function execution")
        return result
    return wrapper

from flask_admin import Admin, BaseView, expose

app = Flask(__name__)
admin = Admin(app)

class MyView(BaseView):
    @expose('/')
    @custom_decorator
    def index(self):
        return "Hello, Flask-Admin!"

admin.add_view(MyView(name='My View', endpoint='myview'))
