ruby-on-rails - 设置 Figaro gem 时未初始化的常量项目 (NameError)

Question

我将 Rails 2.3 应用程序更新到 3.2，这似乎是一个非常简单的过程，但是在设置 Figaro gem 时我遇到了这个错误:

C:\Sites\JustManage>rails generate figaro:install
C:/Sites/JustManage/config/environment.rb:5:in `<top (required)>': uninitialized
 constant Projectmanagement (NameError)
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1
/lib/rails/application.rb:103:in `require_environment!'
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1
/lib/rails/commands.rb:25:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

这是我的 environment.rb 的样子:

# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
Projectmanagement::Application.initialize!

这是我的application.rb 文件:

require File.expand_path('../application', __FILE__)

require 'rails/all'

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

module Railsapp
  class Application < Rails::Application
    config.encoding = "utf-8"

    config.filter_parameters += [
      :password,
      :password_clear,
      :password_verify
    ]

    config.assets.enabled = true
    config.assets.version = '1.0'

  end
end

我以前从未遇到过这个错误，也不知道为什么会这样。

您的应用程序的名称似乎在它需要出现的不同位置不相同。检查以下文件并查看它们是否包含 Projectmanagement::Application 或 Railsapp::应用程序:

• config/application.rb(实际初始化常量)
• config/environment.rb
• config/environments/development.rb
• config/environments/production.rb
• 配置/环境/test.rb
• config/initializers/secret_token.rb
• config/initializers/session_store.rb
• config/mongoid.yml(如果使用 Mongoid)
• config/routes.rb
• config.ru
• 梳理文件
• app/views/layouts/application.html.erb，在标题标签中

然后选择一个名称(Projectmanagement 或 Railsapp)并更改上述文件中的所有名称，使它们匹配。这应该可以解决您遇到的未初始化常量错误。
