我創建使用Rails 3.2.5一個博客，並利用途徑產生的（即我code_entries：code_entries_path，new_code_entry_path等）中的資源路徑已經使用link_to的每一個動作整個網站。突然每當我試圖訪問一個頁面我得到這個錯誤：路線生成的路徑已經停止工作
undefined local variable or method `controller' for #<CodeEntriesController:0x007f887f8b3300>
此錯誤是從我index行動我code_entries_controller.rb，但無論哪個動作我嘗試去到任何控制器我得到這個帶有路由資源路徑的每個link_to錯誤。它之前工作正常，我不確定會造成這種情況。
由於這個問題是我code_entries的情況下，這裏是code_entries_controller.rb，/code_entries/index.html.haml，routes.rb代碼，我已經得到了錯誤，但在行動code_entries#index的背景：
code_entries_controller.rb
class CodeEntriesController < ApplicationController
before_filter :authenticate_action
def index
@entries = CodeEntry.order("created_at desc")
end
def new
@entry = CodeEntry.new
end
def show
@entry = CodeEntry.find_by_id(params[:id])
end
def create
@entry = CodeEntry.new(params[:code_entry])
if @entry.save
redirect_to code_entry_path(@entry), :notice => "#{@entry.title} has been created"
else
puts @entry.errors.messages.inspect
render "new"
end
end
def edit
@entry = CodeEntry.find_by_id(params[:id])
end
def update
@entry = CodeEntry.find_by_id(params[:id])
if @entry.update_attributes(params[:code_entry])
redirect_to code_entry_path(@entry), :notice => "#{@entry.title} has been updated"
else
puts @entry.errors.messages.inspect
render "edit"
end
end
def destroy
@entry = CodeEntry.find_by_id(params[:id])
@entry.destroy
redirect_to code_entries_path, :notice => "#{@entry.title} has been deleted"
end
end
/code_entries/index.html.haml

NameError in Code_entries#index
顯示/Users/kyle/Projects/blog/app/views/code_entries/index.html。HAML其中線＃4提出：
