Question

我将我的rails版本从3.2.13升级到4.0.0，我也升级了我的宝石。当我从本地服务器运行应用程序时，这是我得到的错误：

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'

“匹配”被所有路线的“获取”取代。

这是我们使用inherited_resources的accounts_controller。

class AccountsController < ApplicationController

  inherit_resources

  ssl_required :new, :create

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

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

我无法追踪他们使用的原因，也无法在Gemfile中找到它。请帮我修复此错误。

Answer 1

inherit_resources旨在使使用REST约定的控制器变干。它是一个已弃用的gem，它不再在Rails 4中维护。inherit_resources本质上将从InheritedResources :: Base继承，它具有预先定义的REST方法。

相反，您可以像平常一样删除它并在控制器中定义路线：

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概要，目的是拥有“胖模型和瘦控制器”。你可以找到其他类似的东西，但在我看来，我只是为了可读性而自己添加方法。

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猜测。 Rails 4中的新功能也是增加了强大的参数。在创建和更新操作中，您会看到从私有方法调用account_params，而不是使用方法内的原始参数进行更新。
