Question

我在使用rails创建生成器时出现问题，这是我遇到的错误。我正在尝试创建一个生成器，通过提供商Twilio创建SMS验证。

require "sms_auth-twilio"
NameError: uninitialized constant Twilio::Rails
from /Users/sherodtaylor/.rvm/gems/ruby-1.9.3-p125/gems/sms_auth-twilio-0.0.2/lib/sms_auth-twilio.rb:3:in `<module:Twilio>'
from /Users/sherodtaylor/.rvm/gems/ruby-1.9.3-p125/gems/sms_auth-twilio-0.0.2/lib/sms_auth-twilio.rb:2:in `<top (required)>'
from /Users/sherodtaylor/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:60:in `require'
from /Users/sherodtaylor/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:60:in `rescue in require'
from /Users/sherodtaylor/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:35:in `require'
from (irb):1
from /Users/sherodtaylor/.rvm/rubies/ruby-1.9.3-p125/bin/irb:16:in `<main>'

这是我的代码

 require "sms_auth-twilio/version"
   module Twilio
     class TwilioGenerator < Rails::Generator::Base
     source_root File.expand_path("../generator", __FILE__)
     def add_twilio_initializer
       copy_file "twilio.rb", "config/initializer/twilio.rb"
     end
     # config info for the API
     def twilio_config_info
       copy_file "twilio.yml", "config/twilio.yml"
     end
     # Verification Controller to verify the company
     def copy_verifications 
       copy_file "verifications_controller", "app/contoller/verifications_controller.rb"
     end
   end
 end

重新启动Rails服务器，然后尝试

Answer 2

我不能肯定地说，但这通常不是我在宝石中看到生成器的方式。通常它们与实际的gem_name.rb文件分开。我想如果你将生成器逻辑移动到更常见的lib/generators/generator_name/generator_name.rb，你会有更多的运气。然后，您可以将要复制的文件放在子目录../generator_name/templates/

中

另请注意，您需要将.rb结尾添加到copy_file "verifications_controller,"

要使模板解决问题，您可以按照我编写的here使用生成器的简单gem的布局。
