我正在使用一个rails应用程序，我已经使用了很长一段时间，在此之前还没有一个前端。很长时间我的意思是一年多。我用它来运行基于控制台的数据库。

我现在正试图在上面添加一个简单的前端，一个json，但是到目前为止，由于这个错误，我尝试访问主页users#index或localhost:3000时没有成功。下面是错误(包括webrick启动信息，因为有一些警告)：

    config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

      * development - set it to false
      * test - set it to false (unless you use a tool that preloads your test environment)
      * production - set it to true

      app/controllers/users_controller.rb:1:in `<top (required)>'

这是我的个人资料。由于新版本的rails破坏了一些代码，我冻结了rails版本。

代码语言：javascript
复制
source 'https://rubygems.org'

gem 'nori' #XML TO JSON
gem 'rubillow'

gem 'rails', '4.0.0' #locked version May 25, 2015
gem 'protected_attributes'


## activerecord etc
  gem 'pg'
  gem 'activerecord-postgis-adapter'
  gem 'squeel', '1.2.3'
  gem 'rgeo', '0.3.20' #locked version May 25, 2015
  gem 'nice-ffi'
  gem 'rgeo-shapefile', '0.2.3' #locked version May 25, 2015
  gem 'rgeo-geojson', '0.3.1' #locked version May 25, 2015
  gem 'geocoder', :git => "https://github.com/ddd1600/geocoder.git"
  gem 'georuby' #for parsing kml
## command line related
  gem 'highline'
  gem 'awesome_print'

这是我的routes.rb文件，非常普通：

代码语言：javascript
复制
PostgisRails::Application.routes.draw do
  #resources :users
  root :to => "users#index"
end

我已经检查了与此类似的错误消息，但是没有发现任何类似于我的情况，即所有东西都很普通/默认的情况。

我认为这个错误与某些代码被继承或混合(猴子补丁)到我庞大的代码库中的某个地方的ActionController有关。但是，我所知道的所有猴子补丁都在我的初始值文件夹中，我暂时删除了它，但仍然得到了错误。

告诉我你需要什么额外的信息，我会提供的。谢谢

更多信息

  • 我使用rails s启动服务器

这是我的application.rb文件

代码语言：javascript
复制
require File.expand_path('../boot', __FILE__)

require 'rails/all'
require 'highline/import'
require 'active_record/connection_adapters/postgis_adapter/railtie'

if defined?(Bundler)
  Bundler.require(*Rails.groups(:assets => %w(development test)))
end

module PostgisRails
  class Application < Rails::Application
    config.autoload_paths += Dir["#{config.root}/lib/**/"]
    config.autoload_paths += Dir["#{config.root}/app/modules/**/"]
    config.autoload_paths += Dir["#{config.root}/app/_misc/*.rb"]    
    config.encoding = "utf-8"
    config.filter_parameters += [:password]
    config.active_support.escape_html_entities_in_json = true
    config.active_record.whitelist_attributes = true
    config.assets.enabled = true
    config.assets.version = '1.0'
  end
end

由于我一直处于开发模式，下面是我的development.rb文件

代码语言：javascript
复制
PostgisRails::Application.configure do
  config.cache_classes = false
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.action_mailer.raise_delivery_errors = false
  config.active_support.deprecation = :log
  config.action_dispatch.best_standards_support = :builtin
  config.assets.compress = false
  config.assets.debug = true
end

我将config.eager_load = true添加到application.rb中，在尝试访问主页之前，我尝试启动服务器时立即崩溃。这是它的堆栈跟踪。

请检查app/helpers文件夹中的帮助程序是否都是模块，而不是类，例如：

app/helpers/application_helper.rb应为：

代码语言：javascript
复制
module ApplicationHelper
end

不

代码语言：javascript
复制
class ApplicationHelper
end

另外，如果您在类中包含了某些内容，例如，Concern，则应该将其定义为模块，而不是类
