雷神誤稱爲例外

Question

class B12 < Thor 
    desc "write", "write data into the index" 
    method_option :methods, :desc => "The methods to call on each RawData", :type => :array 
    def write(methods) 
    end 
end 

當我打電話通過

thor b12:write --methods=foo 

文件，我得到

"write" was called incorrectly. Call as "thor b12:write". 

在哪裏的問題？

Answer 1

你有幾件事情會在這裏引發問題。

首先，您使用的是methods，這是一個關於ruby的關鍵字。這將導致各種廢話。使用別的東西，比如my_methods。

其次，您不需要通過my_methods寫入。這會創建一個默認選項，而不是一個命名選項。所以如果你想在這種情況下訪問my_methods，你可以撥打thor b12:write foo。

這個工作，如果你把它叫做：thor b12:write --my_methods=foo

class B12 < Thor 
    desc "write", "write data into the index" 
    method_option :my_methods, :type => :array, :desc => "The methods to call on each RawData" 
    def write 
    puts options.my_methods 
    end 
end
