固定装货目录模块——未启用的固定单元——铁路2至铁路3级
原标题:cant load lib directory modules - uninitialized constant - rails 2 to rails 3 upgrade

I m 目前在铁路中迁移申请2至3

In my lib/ i ve some modules in subdirectories, for example, i ve the lib/search/host_search.rb

with a

  module HostSearch
    def do_search(args)
       #...
    end
  end

then I need to use it in a controller named Discovery::HostController < ApplicationController :

def search_results
   output = HostSearch.do_search(:search_string => @search_string, 
     :page => params[:page],
     :user => @current_user)
   #...
end

But have I get:

uninitialized constant Discovery::HostController::HostSearch

。 我试图将这条线付诸实施,但是它没有工作。

config.autoload_paths += %W(#{config.root}/lib)
config.autoload_paths += Dir["#{config.root}/lib/**/"]
问题回答

I found that moving the module to the lib folder or explicitly including the folder to load worked, in your case config.autoload_paths += %W(#{config.root}/lib/search)

我认为,我们缺乏一些同义词。 另一件事是,如果你不想给申请档案的我,则要求档案,如果我记得,档案是从校准的脚架:搜查/影射;检查。

I think if you put the HostSearch module under a search subdir, (ie in lib/search/host_search.rb), then you need to namespace it:

module Search
  module HostSearch
  end
end

If you don t want to namespace it, you can should move the file into the lib root: lib/host_search.rb.
