我们如何才能将 Pycord 中的一个 Modal 的值（2.x）存储在一个 method/function 然后 return 呢？

Question

class title_input_modal(Modal):
    def __init__(self):
        super().__init__("Audio Title Input")

        self.add_item(InputText(label = "Audio Title", style = discord.InputTextStyle.short))

    async def callback(self, interaction: discord.Interaction):
        
        val = self.children[0].value
        await interaction.response.send_message(val)

如何创建一个方法并存储响应值？如果我尝试从另一个 cog 的 class 方法访问 title_input_modal.children[0]，则会弹出此错误：-

Ignoring exception in view <View timeout=180.0 children=1> for item <Button style=<ButtonStyle.primary: 1> url=None disabled=False label='Play' emoji=<PartialEmoji animated=False name='▶️' id=None> row=None>:

您可以将值作为属性存储在 class 中，并在模式被关闭后访问它。为此，您必须像这样修改 class。

class title_input_modal(Modal):
    def __init__(self):
        super().__init__("Audio Title Input")
        
        #
        self.val = None

        self.add_item(InputText(label = "Audio Title", style = discord.InputTextStyle.short))

    async def callback(self, interaction: discord.Interaction):
        
        self.val = self.children[0].value
        await interaction.response.send_message(val)
        self.stop()

然后从你调用模态的地方，你必须像这样初始化它，这样你就可以访问它的属性

title_modal = title_input_modal()
await ...send_modal(title_modal)
await title_modal.wait()
print(title_modal.val)

如果没有 stop 和 wait 方法，您的机器人不会等待模态交互结束，所以您不会无法访问用户的值。

How can we store the value of a Modal in Pycord (2.x) in a method/function and then return it?

python

discord
