Rails的：未定義的局部變量或方法'選項

-1

require 'rails/generators/base' 
require 'thor' 

module Gem 
    module Generators 

     class ViewsGenerator < Rails::Generators::Base 

      class_option :split, desc: "ABC", type: :boolean, default: false 

      unless options[:split] 
       ... 
      else 
       ... 
      end 

     end 

    end 
end

旁註：它可以添加Command Line Arguments。 +它工作正常，沒有if條件。

例外我越來越：

我不知道發生了什麼事情。

我不知道你的問題是什麼。 – sawa

@sawa根據鏈接的文檔，在提供的代碼片段中應該記錄生成器的命令行參數。 **問題：**爲什麼該片段無法正常工作？ – jonhue

你需要用你的條件在被調用發電機時調用方法：

def new(options) 
    unless options[:split] 
    ... 
    else 
    ... 
    end 
end

嘗試this resource使用雷神打造發電機
