參數丟失錯誤（導軌）

Question

我面臨一個錯誤，即當我嘗試調用函數finalized_request時，它會拋出一個錯誤，指出「param丟失或值爲空：finalizedeal」。由於我是新手，我無法弄清楚我做錯了什麼（我是ROR的新手）。

Answer 1

的代碼是抱怨，因爲你需要:finalizedeal參數（但顯然你不是沿着通過它）加入該.require(:finalizedeal)到的屏幕截圖此代碼：

def finalizedRequest_params 
    params.require(:finalizedeal).permit(:title , :description) 
end 

因此，一種解決方案是簡單地刪除require部分。像這樣：

params.permit(:title , :description) 

#require source

確保一個參數存在。
