在Rails中的Mailboxer收件箱中显示用户名

我在我的Rails应用程序中使用Mailboxer(https://github.com/ging/mailboxer)gem来处理用户之间的私人消息。根据文档,我使用= render mailbox.inbox显示登录用户的所有会话(消息)列表。但是,该方法仅输出消息的主题。我需要显示消息的发件人以及主题。如何编辑此输出以显示发件人姓名?

SQL表显示发件人名称未存储在会话表中,而是存储在notification_on_conversation_id(一对多)的通知表中。我尝试使用<%= conversation.notifications.sender_id %>,但我收到以下错误:

NoMethodError in Conversations#index
undefined method `notifications' for nil:NilClass

我可以将哪些内容添加到会话控制器和视图中以显示会话的用户和主题?

谢谢!

对话控制器:

class ConversationsController < ApplicationController
  before_filter :authenticate_user!
  helper_method :mailbox, :conversation

  def create
    recipient_emails = conversation_params(:recipients).split(',')
    recipients = User.where(email: recipient_emails).all

    conversation = current_user.
      send_message(recipients, *conversation_params(:body, :subject)).conversation

    redirect_to conversation
  end

  def reply
    current_user.reply_to_conversation(conversation, *message_params(:body, :subject))
    redirect_to conversation
  end

  def trash
    conversation.move_to_trash(current_user)
    redirect_to :conversations
  end

  def untrash
    conversation.untrash(current_user)
    redirect_to :conversations
  end

  private

  def mailbox
    @mailbox ||= current_user.mailbox
  end

  def conversation
    @conversation ||= mailbox.conversations.find(params[:id])
  end

  def conversation_params(*keys)
    fetch_params(:conversation, *keys)
  end

  def message_params(*keys)
    fetch_params(:message, *keys)
  end

  def fetch_params(key, *subkeys)
    params[key].instance_eval do
      case subkeys.size
      when 0 then self
      when 1 then self[subkeys.first]
      else subkeys.map{|k| self[k] }
      end
    end
  end
end

使用receipt.notification.sender_id和.sender_type

可以使用

sender_id

对于任何会话,您都可以使用以下方式检索收据: @receipts = conversation.receipts_for
