如何修复控制器中未初始化的常量

How to fix Uninitialized Constant in Controller

我得到一个:

uninitialized constant ProfilesController::EUserPofile

尝试时出错:

class ProfilesController < ApplicationController
  def index
    #@profiles = EUserProfile.all
  end

  def preview
    @profiles = EUserPofile.all
  end

end

它在索引时工作正常,但在预览时会崩溃。

这是我的路线文件:

Rails.application.routes.draw do
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
  get 'welcome', to: 'pages#home'
  get 'profiles', to: 'profiles#index'
  get 'login', to: 'login#login'

  resources :profiles do
    get 'preview', on: :member
  end

end

有一个错字:EUserPofile -> EUserProfile
