我在 rails 3.2 应用程序中有一个管理员命名空间。我想使用https://github.com/edendevelopment/paginate_alphabetically上的 paginate_alphabetically gem 对作者的 postgres 数据库进行分页。

app/controllers/admin 中的控制器（Admin::AuthorsController < AdminController 类）具有：

def index
    @authors = Author.includes(:stories).alphabetical_group(params[:letter])
    respond_to do |format|
        format.html # show.html.erb
        format.json { render json: @authors }
    end
end

app/models 中的 author.rb 模型有： paginate_alphabetically :by => :last_name

app/views/admin/index.html.erb 中的作者视图具有：

<ul class='pagination'>
<%- Author.pagination_letters.each do |letter| -%>
<li><%= link_to(letter, admin_authors_path(:letter => letter)) %></li>
<%- end -%>
</ul>

这似乎正在生成正确的 html，其中：

<ul class='pagination'>
<li><a href="/admin/authors?letter=A">A</a></li> 
...etc.
</ul>

但是点击时链接不会去任何地方。红宝石输出说明如下：

Started GET "/admin/authors?letter=A" for 127.0.0.1 at 2012-08-14 18:18:15 -0400

 Rendered admin/authors/index.html.erb within layouts/admin (149.5ms)

在 171 毫秒内完成 200 次 OK（查看次数：96.4 毫秒 | ActiveRecord：73.3 毫秒）

当我实际输入 url localhost:3000/admin/authors?letter=A （或任何其他字母）时，我会得到一个页面，其中包含我想要的内容，一个按字母顺序排列的作者列表，具体取决于字母。它只是不适用于上述链接。

在我的 routes.rb 文件中，我有：

namespace :admin do
  resources :authors
  resources :issues
  resources :stories  
  root :to => 'authors#index
end

想法？
