nested_messages没有显示以前的消息

Question

我一直在遵循轨道铸262祖先的宝石，所以我可以使用嵌套消息。我遇到的问题是，当我查看消息时，它没有列出树中的其他消息。消息ID 26 ancestry是7（7是被回复的消息）。消息ID 27 ancestry是7,26。当我查看原始消息ID 7时，它会在三个不同的时间复制内容。如果我查看消息ID 26，它会重复它的内容两次。如果我查看消息ID 27，它不显示重复。

它应该如何工作是当我查看这些消息ID时，它应该列出ancestry中的内容。

我不知道我在做什么错。

show.html.rb：

<p> 
     <strong>From:</strong> 
     <%= @message.sender %> 
</p> 
<p> 
     <strong>To:</strong> 
     <%= @message.recipient %> 
</p><div class="message"> 
    <div class="created_at"><%= @message.created_at.strftime('%B %-d, %Y %l:%M%P') %></div> 
    <div class="content"><P> 
<%= nested_messages @message.subtree.arrange(:order => :created_at) %> 

    </div> 
    <div class="actions"> 
     <% if @message.recipient == @user %> 
     <%= link_to "Reply", new_user_message_path(@user, :parent_id => @message) %><% end %> 
    | 
    <%= link_to "Delete", [current_user, @message], :confirm => 'Are you sure you want to delete this message?', :method => :delete %> 

    </div> 
</div> 

<%= render "form" %> 
<p> 
    <% if @message.next %> 
     <%= link_to 'Next', user_message_path(current_user, @message.next) %> 
    <% end %> 
    <% if @message.previous %> 
     <%= link_to 'Previous', user_message_path(current_user, @message.previous) %> 
    <% end %> 
    </p> 

<p> 
    <% if @message.recipient == @user %> 

    <%= link_to "Reply", new_user_message_path(@user, :reply_to => @message.sender.id) %> 

    | 
    <% end %> 
    <%= link_to "Inbox", user_messages_path(current_user, :mailbox=>:inbox)%> 
    | 
    <%= link_to "Delete", [current_user, @message], :confirm => 'Are you sure you want to delete this message?', :method => :delete %> 

</p> 

messages_helper.rb：

module MessagesHelper 
    def nested_messages(messages) 
    messages.map do |message, sub_messages| 
     render(message) + content_tag(:div, nested_messages(sub_messages), :class => "nested_messages") 
    end.join.html_safe 
    end 
end 

_message.html.erb：

<div class="message"> 
    <div class="created_at"><%= message.created_at.strftime("%B %d, %Y") %></div> 
    <div class="content"> 
    <%=h @message.body %> 
    </div> 
</div> 

检查日志：

Answer 1

在_message.html.erb尝试切换：

<%=h @message.body %> 

到：

<%= h message.body %> 

已设置用于部分时MessagesHelper呼叫render是message的变量。
