state_machine gem 레일과 통합 4

Question

내 레일 4 앱으로 state_machine gem 사용에 문제가 있습니다. A는 제공된 레일 가이드에 기재된 컬럼 호 상태를 포함하는 모델을 가질 http://gistflow.com/posts/679-state-machine-with-rails-basics

있지만 다음과 같이 내 state_machine를 정의 할 때 : 내 IssueConntroller

class IssuesController < ApplicationController 

before_filter :find_issue, except: [:index, :new, :create] 

def index 
    @issues = Issue.all 
end 

def new 
    @issue = Issue.new 
end 

def create 
    @issue = Issue.new(issue_params) 
    respond_to do |format| 
     if @issue.save 
      format.html {redirect_to @issue, :flash => { :success => "Issue succesfully created." } } 
      format.json {head :no_content} 
     else 
      format.html {render action: 'new'} 
      format.json { render json: @issue.errors, status: :unprocessable_entity } 
     end 

    end 
end 

def show 
    @note = Note.new 
    @note.issue_id = @issue.id 
end 

def edit 
end 

def update 
    respond_to do |format| 
     if @issue.update(issue_params) 
     format.html { redirect_to @issue, :flash => { :success => 'Issue was successfully updated.' }} 
     format.json { head :no_content } 
     else 
     format.html { render action: 'edit' } 
     format.json { render json: @issue.errors, status: :unprocessable_entity } 
     end 
    end 
end 

def destroy 
    @issue.destroy 

    flash[:error]= "Issue '#{@issue.title}' Deleted!" 

    redirect_to issues_path 
end 

private 
def issue_params 
    params.require(:issue).permit(:title, :description) 

end 

def find_issue 
    @issue = Issue.find(params[:id]) 
end 

end 

여기

class Issue < ActiveRecord::Base 
validates :title, :description, presence: true 
has_many :notes 

state_machine :initial => :new do 
    state :new, value: 0 
    state :analysed, value: 1 
    state :assigned, value: 2 
    state :inprogress, value: 3 
    state :inreview, value: 4 
    state :validation, value: 5 
    state :resolved, value: 6 
    state :cancelled, value: 7 
    state :closed, value: 8 
    state :rejected, value: 9 
    state :reopened, value: 10 
end 

def next 
    Issue.where("id > ?", self.id).first || Issue.first 
end 

def prev 
    Issue.where("id < ?", self.id).last || Issue.last 
end 
end 

인

IssuesController # index에서 NoMethodError에 대해 정의되지 않은 메소드`state_machine '에 빠졌습니다. 물론 gemfile에 state_machine 줄을 추가하고 번들 설치 명령을 실행했습니다. 여기

는 아무런 문제가 없습니다 추적

이 문제로 저를 도와 주셔서 감사합니다 ... 레일 응용 프로그램에서로드되지 않습니다 보석처럼 보인다 당신 코드에서 묶음으로 번들을 다시로드하려고 시도 할 때 상태, 모델 및 물론 동일한 이벤트에 대한 값을 사용했기 때문에 또는 ìnteger을 추가하는 것을 잊지 마십시오. 은

입니다. 상태 머신의 정의로

event :add_new do 
     transition new: :analysed
