小编tri*_*ror的帖子

我是rails的新手,我尝试根据教程创建一个论坛应用程序.这是我的论坛页面,但我一直收到错误:

syntax error, unexpected keyword_ensure, expecting end-of-input

Extracted source (around line #33):
30 
31    <p><% if admin? %><%= link_to "New Forum", new_forum_path %><% end %></p>  

这是抛出错误的论坛索引页面:

<% title "Forums" %>  

<table>  
  <tr>  
    <th width="70%">Forum</th>  
    <th width="30%">Last Post</th>  
  </tr>  
  <% for forum in @forums %>  
    <tr>  
      <td><h4><%= link_to h(forum.name), forum_path(forum.id) %></h4>  
        <small><%= forum.topics.count %> topics</small><br />  
        <%=h forum.description %></td>  
      <td class="right">
      <% if forum.most_recent_post %>
      <%= distance_of_time_in_words_to_now forum.most_recent_post.last_post_at %>
       ago by 
       <%= link_to forum.most_recent_post.user.username, "/users/#{forum.most_recent_post.last_poster_id}" %>
       <% else %>no posts<% end …

我正在尝试使用此页面中的教程实现论坛页面!这里论坛是一个模型.这是控制器代码:

class ForumsController < ApplicationController
  before_filter :admin_required, :except => [:index, :show]

  def index
    @forums = Forum.all
  end

  def show
    @forum = Forum.find(params[:id])
  end

  def new
    @forum = Forum.new
  end

  def create
    @forum = Forum.new(params[:forum])
    if @forum.save
      redirect_to @forum, :notice => "Successfully created forum."
    else
      render :action => 'new'
    end
  end

  def edit
    @forum = Forum.find(params[:id])
  end

  def update
    @forum = Forum.find(params[:id])
    if @forum.update_attributes(params[:forum])
      redirect_to @forum, :notice  => "Successfully updated forum."
    else
      render :action => 'edit'
    end …
