无法将局部变量传递到按钮装饰器中

Question

如何将

self.canCraft

变量传递到装饰器中？我明白这个问题为什么不起作用，但我找不到解决方案。我不想用全局变量来做到这一点。

class CraftView(discord.ui.View):
    def __init__(self, viewOwner, craftItem, canCraft):
        super().__init__()
        self.viewOwner = viewOwner
        self.craftItem = craftItem
        self.canCraft = canCraft

    @discord.ui.button(label="Craft", style=discord.ButtonStyle.primary, emoji="🔨", disabled=self.canCraft)
    async def button_callback(self, interaction: Interaction, button: ui.Button):
        pass

您可能最好对 discord.ui.Button 进行子类化并将其添加到这样的视图中 -

import discord

class CraftButton(discord.ui.Button):
    def __init__(self, label:str, emoji:str, disabled:bool, style:discord.ButtonStyle=discord.ButtonStyle.primary):
        super().__init__(label=label, emoji=emoji, disabled=disabled, style=style)

    async def callback(interaction:discord.Interaction):
        ...

class CraftView(discord.ui.View):
    def __init__(self, view_owner, craft_item, can_craft):
        super().__init__()
        self.view_owner = view_owner
        self.craft_item = craft_item
        self.add_item(CraftButton("Craft", "🔨", can_craft))
