discord.py报错：'Button'对象无'response'属性及房间选择需求

问题描述 #

我正在开发一款连接Discord与Google Sheets的房间预订机器人，执行!reserver指令会弹出一个按钮，但点击按钮时触发交互错误，报错信息为：AttributeError: 'Button' object has no attribute 'response'。同时希望实现点击按钮后显示房间选择菜单的功能。

修复与功能实现方案 #

核心问题解析 #

1. 交互响应方法错误：Discord.py中interaction.response没有send方法，正确的发送交互响应方法是send_message，这是导致AttributeError的直接原因。
2. 流程逻辑缺失：原代码中用户没有途径选择房间，点击按钮时self.room始终为None，不符合“点击按钮显示房间选择菜单”的需求。

    await interaction.response.send_message(

    )
    self.view.stop()


class ReservationView(View):

  def __init__(self):
    super().__init__()

  @discord.ui.button(label="Réserver", style=discord.ButtonStyle.green)
  async def reserve_button(self, button: discord.ui.Button,
                           interaction: discord.Interaction):
    try:
      # 创建包含房间选择菜单的View
      select_view = View()
      select_view.add_item(RoomSelect())
      # 发送带选择菜单的交互响应

bot.run('TOKEN')

关键改动说明 #

1. 修正交互响应方法：将interaction.response.send()替换为interaction.response.send_message()，符合Discord.py的API规范。
2. 重构View逻辑：点击“Réserver”按钮时，动态生成包含房间选择菜单的View并发送，实现“点击按钮显示房间选择菜单”的需求。
3. 优化选择回调：在RoomSelect的回调中直接处理房间选择结果，可在此处扩展写入Google Sheets的业务逻辑。
