操作控制器：：路由错误 - 未定义的局部变量或方法“inherit_resources”升级后

Question

我将rails版本从3.2.13升级到4.0.0，我还升级了我的gem。当我从本地服务器运行应用程序时，这是我收到的错误：

在2016-06-24 11:54:37 0530开始获取127.0.0.1的“/signup.html”

在我以前的版本中，routes文件是这样的:

 match '/signup'   => 'accounts#new', :plan => 'year'

升级后，我将其更改为：

get '/signup'   => 'accounts#new', :plan => 'year'

对于所有路由，“匹配”将替换为“get”。

这是我们用inherited_resourcesaccounts_controller。

class AccountsController < ApplicationController

  inherit_resources

  ssl_required :new, :create

  before_filter :authenticate_user!, :except => [:new, :create]

  ...................
end

我找不到它们被使用的原因，在Gemfile中也找不到。请帮我修复这个错误。

inherit_resources旨在干涸使用REST约定的控制器。它是一个已弃用的gem，不再在Rails 4中维护。inherit_resources将基本上继承自预定义了REST方法的::Base。

相反，您可以删除它并在控制器中定义路由，就像您通常所做的那样：

class AccountsController < ApplicationController
  ssl_required :new, :create

  before_filter :authenticate_user!, :except => [:new, :create]

  def index
    @accounts = Accounts.all
  end

  def show
    @account = Account.find(params[:id])
  end

  def new
    @account = Account.new
  end

  def create
    @account = Account.new(account_params)
    if @account.save
      redirect_to @account
    else
      render 'new'
    end
  end

  def edit
    @account = Account.find(params[:id])
  end

  def update
    @account = Account.find(params[:id])
    if @account.update_attributes(account_params)
      flash[:notice] = "Successfully updated account!"
      redirect_to @account
    else
      render 'edit'
    end
  end

  def destroy
    @account = Account.find(params[:id])
    @account.destroy
    redirect_to accounts_path
  end

  private

    def account_params
      params.require(:account).permit(:name, :email, etc) # Look up strong params if you are unfamiliar. The name, email, etc. are going to be the only permitted params passed in the methods above as a safety feature so you have to permit the fields being created here.
    end

这是继承资源添加到控制器中的大纲，目的是拥有“胖模型和瘦控制器”。你可以找到其他做类似事情的宝石，但在我看来，为了便于阅读，我宁愿自己添加这些方法。

编辑：它正在添加这些方法定义，但根据您的应用程序，将定义这些方法中的内容。这将是我最好的粗略估计。Rails 4中的新功能是添加了强参数。在创建和更新操作中，您可以看到account_params是从私有方法调用的，而不是使用方法中的原始参数进行更新。
