無法將傳遞的參數更改爲rake任務

Question

當我爲參數指定值時，它是一個字符串。所以我試圖把它變成一個整數，但這不起作用。

代碼是這樣的：

task :fetch_video, [:fetch_number] => :environment do |t, args| 
    args.with_defaults(:fetch_number => 4) 
    args.fetch_number = args.fetch_number.to_i 
    puts args.fetch_number.class 

    #run rake fetch_video[10]， 
    #returns: String 
end 

我都做什麼錯誤？

你正試圖編寫args變量，我認爲你不能這樣做。試試這個：

task :fetch_video, [:fetch_number] => :environment do |t, args| 
    args.with_defaults(:fetch_number => 4) 
    local_fetch_number = args.fetch_number.to_i 
    puts local_fetch_number.class 
end
