How to get a channel object using the client (in select callback) discord.py

问题

我在选择回调中遇到了获取频道对象（使用客户端）的问题。我不想使用公会ID进行获取，因为一个用户可能在DM频道中（此命令必须适用于一个用户在普通频道中，另一个用户在文本频道中）。

  1. @discord.ui.button(label="确认", custom_id='confirm', style=discord.ButtonStyle.green)
  2. async def confirm(self, interaction: discord.Interaction, button: discord.ui.Button):
  4.     initialize_trade(self.user.id, interaction.user.id, self.user_channel, interaction.channel.id, self.user_message, self.own_message)
  6.     inventory = get_inventory(interaction.user.id)
  7.     user1_inv, user2_inv = [], []
  9.     formatted_inventory = []
  10.     count_dict = {}
  11.     for item in inventory:
  12.         count_dict[item] = count_dict.get(item, 0) + 1
  13.         formatted_inventory.append(f"{item} ({count_dict[item]})" if count_dict[item] > 1 else item)
  15.     await interaction.response.edit_message(content='交易已确认！', view=TradeView(self.user, 2, formatted_inventory, user1_inv, user2_inv))
  1. class TradeView(discord.ui.View):
  2.     def __init__(self, other_user: discord.User, usertype, inventory, user1inv, user2inv):
  3.         super().__init__(timeout=60)
  5.         self.other_user = other_user
  6.         self.inventory = inventory
  7.         self.user1inv = user1inv
  8.         self.user2inv = user2inv
  10.         self.usertype = usertype
  12.         self.select_callback.options = [discord.SelectOption(label=item) for item in inventory]
  14.         self.select_callback.max_values = len(inventory)
  16.     @discord.ui.select(placeholder="选择要交易的物品", min_values=1, options=[])
  17.     async def select_callback(self, interaction: discord.Interaction, select):
  18.         if self.usertype == 1:
  19.             configure_user1_inv(interaction.user.id, self.other_user.id, select.values)
  20.             channel_id, msg_id = get_user2_message(interaction.user.id, self.other_user.id)
  21.         else:
  22.             configure_user2_inv(interaction.user.id, self.other_user.id, select.values)
  23.             channel_id, msg_id = get_user1_message(self.other_user.id, interaction.user.id)
  25.         channel = self.bot.get_channel(channel_id)
  26.         message = await channel.fetch_message(msg_id)
  28.         await message.edit(content=f'编辑的消息！{select.values}')
  29.         await interaction.response.edit_message(content=f"{select.values}")

I have an issue getting a channel object (using the client) within a select callback. I don't want to fetch using a guild id because one user will be in a DM channel (this command will have to work for one user in a normal channel, and the other in a text channel).

  1.     @discord.ui.button(label="Confirm", custom_id='confirm', style=discord.ButtonStyle.green)
  2.     async def confirm(self, interaction: discord.Interaction, button: discord.ui.Button):
  4.         initialize_trade(self.user.id, interaction.user.id, self.user_channel, interaction.channel.id, self.user_message, self.own_message)
  6.         inventory = get_inventory(interaction.user.id)
  7.         user1_inv, user2_inv = [], []
  9.         formatted_inventory = []
  10.         count_dict = {}
  11.         for item in inventory:
  12.             count_dict[item] = count_dict.get(item, 0) + 1
  13.             formatted_inventory.append(f"{item} ({count_dict[item]})" if count_dict[item] > 1 else item)
  15.         await interaction.response.edit_message(content='Trade confirmed!', view=TradeView(self.user, 2, formatted_inventory, user1_inv, user2_inv))
  1. class TradeView(discord.ui.View):
  2.     def __init__(self, other_user: discord.User, usertype, inventory, user1inv, user2inv):
  3.         super().__init__(timeout=60)
  6.         self.other_user = other_user
  7.         self.inventory = inventory
  8.         self.user1inv = user1inv
  9.         self.user2inv = user2inv
  11.         self.usertype = usertype
  13.         self.select_callback.options = [discord.SelectOption(label=item) for item in inventory]
  15.         self.select_callback.max_values = len(inventory)
  18.     @discord.ui.select(placeholder="Select Items to Trade", min_values=1, options=[])
  19.     async def select_callback(self, interaction: discord.Interaction, select):
  20.         if self.usertype == 1:
  21.             configure_user1_inv(interaction.user.id, self.other_user.id, select.values)
  22.             channel_id, msg_id = get_user2_message(interaction.user.id, self.other_user.id)
  23.         else:
  24.             configure_user2_inv(interaction.user.id, self.other_user.id, select.values)
  25.             channel_id, msg_id = get_user1_message(self.other_user.id, interaction.user.id)
  29.         channel = self.bot.get_channel(channel_id)
  30.         message = await channel.fetch_message(msg_id)
  32.         await message.edit(content=f'EDITED MESSAGE! {select.values}')
  33.         await interaction.response.edit_message(content=f"{select.values}")

Anything helps :)! Sorry if this is a little confusing/not clear.

你可以简单地将机器人传递给__init__方法的另一个参数中：

  1. class TradeView(discord.ui.View):
  2.     def __init__(self, other_user: discord.User, usertype, inventory, user1inv, user2inv, bot):
  3.         super().__init__(timeout=60)
  5.         self.bot = bot
  7.         self.other_user = other_user
  8.         self.inventory = inventory
  9.         self.user1inv = user1inv
  10.         self.user2inv = user2inv
  12.         self.usertype = usertype
  14.         self.select_callback.options = [discord.SelectOption(label=item) for item in inventory]
  16.         self.select_callback.max_values = len(inventory)
  18.     # ...其余的代码

然后在创建视图时简单地传递机器人实例：

  1.     @discord.ui.button(label="确认", custom_id='confirm', style=discord.ButtonStyle.green)
  2.     async def confirm(self, interaction: discord.Interaction, button: discord.ui.Button):
  4.         initialize_trade(self.user.id, interaction.user.id, self.user_channel, interaction.channel.id, self.user_message, self.own_message)
  6.         inventory = get_inventory(interaction.user.id)
  7.         user1_inv, user2_inv = [], []
  9.         formatted_inventory = []
  10.         count_dict = {}
  11.         for item in inventory:
  12.             count_dict[item] = count_dict.get(item, 0) + 1
  13.             formatted_inventory.append(f"{item} ({count_dict[item]})" if count_dict[item] > 1 else item)
  15.         await interaction.response.edit_message(
  16.             content='交易确认！', 
  17.             view=TradeView(
  18.                 self.user, 2, formatted_inventory, user1_inv, user2_inv, interaction.client  # 重要
  19.             )
  20.         )
英文:

You can simply pass the bot into another argument of the __init__ method:

  1. class TradeView(discord.ui.View):
  2.     def __init__(self, other_user: discord.User, usertype, inventory, user1inv, user2inv, bot):
  3.         super().__init__(timeout=60)
  5.         self.bot = bot
  7.         self.other_user = other_user
  8.         self.inventory = inventory
  9.         self.user1inv = user1inv
  10.         self.user2inv = user2inv
  12.         self.usertype = usertype
  14.         self.select_callback.options = [discord.SelectOption(label=item) for item in inventory]
  16.         self.select_callback.max_values = len(inventory)
  18.     # ...rest of the code

And simply pass the bot instance when creating the view:

  1.     @discord.ui.button(label="Confirm", custom_id='confirm', style=discord.ButtonStyle.green)
  2.     async def confirm(self, interaction: discord.Interaction, button: discord.ui.Button):
  4.         initialize_trade(self.user.id, interaction.user.id, self.user_channel, interaction.channel.id, self.user_message, self.own_message)
  6.         inventory = get_inventory(interaction.user.id)
  7.         user1_inv, user2_inv = [], []
  9.         formatted_inventory = []
  10.         count_dict = {}
  11.         for item in inventory:
  12.             count_dict[item] = count_dict.get(item, 0) + 1
  13.             formatted_inventory.append(f"{item} ({count_dict[item]})" if count_dict[item] > 1 else item)
  15.         await interaction.response.edit_message(
  16.             content='Trade confirmed!', 
  17.             view=TradeView(
  18.                 self.user, 2, formatted_inventory, user1_inv, user2_inv, interaction.client  # important
  19.             )
  20.         )
