Question

在我的rails应用中，我收到以下错误：

NameError in ProjectsController#index
app/controllers/projects_controller.rb:6:in `index'

我的路线看起来像这样：

RailsStarter::Application.routes.draw do
resources :projects

root :to => 'pages#home'
match '/' => 'pages#home'
match '/overview' => 'pages#overview'
match '/recruitmentInfo' => 'pages#recruitmentInfo'

问题控制器：

 class ProjectsController < ApplicationController

 # GET /projects
 # GET /projects.json
 def index
 @projects = ::Project.all

 respond_to do |format|
   format.html # index.html.erb
   format.json { render json: @projects }
 end
end

到目前为止，我的调查显示Project尚未初始化，但这并不重要，因为它是一个构造函数，在它自己的类中。我甚至尝试通过将此行config.autoload_paths += %W( #{config.root}/app/controllers)添加到application.rb来预编译。似乎没有什么工作。任何想法将不胜感激。谢谢！

[解决]：

1 Reboot machine - the command must interfere with another server process
2 Check active_support gem versions by running `gem list` and remove them all
3 Remove `Gemfile.lock`
3 Run `bundle install` - this will add back your new version of gemfile
4 Run `rails generate model Project` again

现在应该修复了！

ProjectsController中的NameError #index
