rails應用遍歷Controllers目錄並取出所有的Controller和action

    今天在javaeye論壇上看到有人有這個需求,順手寫了下。原理就是通過遍歷Controllers目錄,並用正規表示式取出Controller名和它所有的action。

    @controllers=Hash.new
    path
="#{RAILS_ROOT}/app/controllers/"
    Dir
.new(path).entries.each do |f|
      
if !f.index('.rb').nil? and f.index('.rb')>0
        
        controller
=File.open(path+f.to_s)
        s
=controller.read
         
/class\s(.*)\s\match(s)
        controller_name
=$1.to_s
        actions
=[]
        s
.scan(/def\s(.*)\s/).each|action| actions<<(action[0]) }
        
@controllers[controller_name]=actions
        controller
.close
      end
    end
    
    
@controllers.each_pair do |name, actions|
      actions
.each do |action| 
        puts 
|name<<" "<<action
      end
    end
