Question

在gem中创建生成器时遇到问题。当我运行rails g时，会显示生成器：

Supportator:
  supportator:initializer

但是当我使用rails generate supportator:initializer运行生成器时，会发生以下错误：

Could not find generator supportator:initializer.

这是生成器的代码：

require 'rails/generators'

module Supportator
  class InitializerGenerator < Rails::Generators::Base
    source_root File.expand_path("../templates", __FILE__)

    def create_initializer_file
      copy_file '_browser_validator.html.haml', 'app/views/_browser_validator.html.haml'
      copy_file 'en_supportator.yml' , 'config/locales/en_supportator.yml'
      copy_file 'es_supportator.yml' , 'config/locales/es_supportator.yml'
    end

  end
end

这是引擎的代码：

module Supportator
  require 'rails'
  class Engine < ::Rails::Engine
  end
end

你知道为什么会这样吗？

Answer 1

更改

lib/generators/supportator/supportator_generator.rb

到

lib/generators/supportator/initializer_generator.rb

您的班级名称为InitializerGenerator，因此文件名应为initializer_generator.rb。否则，rails将无法找到它。

对于使用rails g supportator:initializer的情况，rails会在initializer_generator.rb目录中查找生成器文件lib/generators/supportator。

Answer 2

问题是文件的目录和名称。到以下生成器：

require 'rails/generators'

module Supportator
  module Generators
      class InstallGenerator < ::Rails::Generators::Base
        source_root File.expand_path("../../../templates", __FILE__)

        def create_initializer_file
          copy_file '_browser_validator.html.haml', 'app/views/_browser_validator.html.haml'
          copy_file 'en_supportator.yml' , 'config/locales/en_supportator.yml'
          copy_file 'es_supportator.yml' , 'config/locales/es_supportator.yml'
        end

      end
  end
end

目录和文件名应为：

/lib
  /generators
    /supportator
      /install
        /install_generator.rb
