Question

我想生成前缀为#!字符串的网址，以便使用ajax（sammy.js）加载网页。

我在application_helper.rb中编写了一个帮助方法：

def method_missing(method, *args, &block)
  super(method, *args, &block)
rescue NoMethodError => e
  match   = method.to_s.match /^sammy_(\w*_path)$/
  prepend = '#!'
  unless match.nil?
    prepend + send(match[1].to_sym, *args, &block)
  else
    raise e
  end
end

它在开发环境中运行良好，但在生产中出错。

ActionView::TemplateError (column_url failed to generate from {:controller=>"columns", :action=>"show", :id=>#<Column id: 2, author_id: 3, parent_id: nil ...>}, expected: {:controller=>"columns", :action=>"show"}, diff: {:id=>#<Column id: 2, author_id: 3, parent_id: nil ...>}) on line #3 of vendor/plugins/theme/app/views/posts/_post_box.html.erb:

2:   <div class="inner">
3:     <p class="post-column"><%= link_to column.title, sammy_column_path(column) %></p>
4:     <h2><%= link_to post_box.title, sammy_column_post_path(column, post_box) %></h2>
5:     <p class="post-author"><a href="#/szerzo/1-fabian-terez"><%= post_box.author.name %></a></p>
