Question

我正在尝试让Mailboxer gem在Rails 3.1应用程序中工作......我有新的消息功能正常工作，但回复一个对话一直给我一个undefined method 'is_trashed?' for nil:NilClass错误。

我一直关注宝石网站here上的自述信息，并查看示例邮箱应用here。

这是我的控制器：

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

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

  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
    conversation = current_user.reply_to_conversation(conversation, *message_params(:body)).conversation
    redirect_to conversation
  end

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

  def untrash
    conversation.untrash(current_user)
    redirect_to :back
  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

这是我的回复表格：

<%= simple_form_for :message, url: [:reply, conversation] do |f| %>
  <%= f.input :body, as: :text, :input_html => { :cols => 50, :rows => 3 } %>
  <div >
    <%= f.button :submit, "Send", class: 'btn btn-primary' %>
  </div>
<% end %>

新会话正在运行，但出于某种原因，我一直在reply_to_conversation功能上遇到错误。任何帮助将不胜感激！

显然，服务器只需要重新启动...不确定原因，因为这只是在控制器和视图方面。它现在正在运作！

如何解决Mailboxer回复未定义的方法`is_trashed？'错误？
