我遵循了一个教程，并在我的rails应用程序中添加了消息传递功能。

昨天，我删除了一些用户。现在，当我转到我的messages链接时，我收到了一条错误消息：“我们很抱歉，但是出了问题。如果您是应用程序所有者，请查看日志以获得更多信息。”通常会在出现错误时显示。

我看到了日志，发现我一定是删除了发送信息的人。

我认为它是在试图检索一个不存在的用户的消息。

代码语言：javascript
复制
ActionView::Template::Error (undefined method `avatar' for nil:NilClass):

我怎样才能解决这个问题？

请大家分享一下如何删除所有邮件并重新开始吗？因为这些消息不重要。

如何清除所有的邮箱表并重新开始？帮帮忙吧。

这是原木。

我变得不耐烦了，把他们都毁了。

代码语言：javascript
复制
irb(main):002:0> Mailboxer::Conversation.destroy_all

现在错误消失了，我可以发送消息了。

我不知道如何删除我最近删除的800个用户的对话。

你是正确的。应用程序正在对不存在的用户调用方法。例如：`

代码语言：javascript
复制
<%= link_to conversation.last_message.sender.name...

(conversation.last_message)保存，但发送方不存在。

如果您想从零开始启动数据库，可以运行(rake db:重置)，这将删除、创建和迁移数据库。

要解决此问题，请创建一个方法，该方法在用户每次取消或删除其帐户时运行，并删除该用户的会话。这是你的控制台(rails c)，它会删除第一个用户的对话。`

代码语言：javascript
复制
User.first.mailbox.conversations.each do |i| i.delete end

如果您仍然希望将对话显示给没有取消帐户的其他用户。您必须将该名称保存在其他地方，或者向用户显示发件人删除了他的帐户。`

代码语言：javascript
复制
<% if conversation.sender == null %>
  <%= conversation.last_message %>
  <p>User of this conversation deleted his/her account</p>
<%else%>
  <%= conversation.last_message %>
  <%= conversation.last_message.sender.name %>
<% end %>

这听起来像是一种未经优化的方法，就是在模型上循环使用acts_as_messageable..like MyModel.each do |mod| mod.mailbox.conversations.destroy_all end添加消息传递功能。
