ruby-on-rails - 在 Rails 应用程序中配置 spec 文件夹时出现问题

Question

我正在使用 rspec 在 Rails4 中练习 TDD 的东西，并打算通过命令创建几个文件夹，例如factories, model, requests, controller。所以我将这样的行添加到config/application.rb：

config.generators do |g| 
  g.test_framework :rspec, 
    :model_specs => true, 
    :view_specs => false, 
    :helper_specs => false, 
    :routing_specs => false, 
    :controller_specs => true, 
    :request_specs => true 
  g.fixture_replacement :factory_girl, :dir => "spec/factories" 
end

然而。当我rails g rspec:install在命令行中运行时。系统返回错误：

/home/rayvonmice/workspace/kulu/config/application.rb:14:in `<top (required)>': undefined local variable or method `config' for main:Object (NameError)
    from /home/rayvonmice/.rvm/gems/ruby-2.0.0-p247@global/gems/railties-4.0.0/lib/rails/commands.rb:44:in `require'
    from /home/rayvonmice/.rvm/gems/ruby-2.0.0-p247@global/gems/railties-4.0.0/lib/rails/commands.rb:44:in `<top (required)>'
    from bin/rails:4:in `require'
    from bin/rails:4:in `<main>'

所以我不太明白config/application.rb文件有什么问题。这是否意味着我只能手动生成这些文件夹？

看起来你config在它定义的地方之外调用。

尝试将您的代码移动到以下开头的块中：

module Kulu
  class Application < Rails::Application
  ...
  config.generators do |g| 
    g.test_framework :rspec, 
      :model_specs => true, 
      :view_specs => false, 
      :helper_specs => false, 
      :routing_specs => false, 
      :controller_specs => true, 
      :request_specs => true 
    g.fixture_replacement :factory_girl, :dir => "spec/factories" 
  end
  ...
end
