rails名稱空間表單不會將數據寫入數據庫

我剛接觸rails並想知道爲什麼我的表單不會將數據寫入數據庫？如果我顯示控制器的數據，如rails名稱空間表單不會將數據寫入數據庫

render text: params[:post].inspect

它顯示我正確的細節。如果我發送表單到數據庫只顯示一個新的ID和created_at和updated_at數據。

也許還有誰可以幫我...

這裏有我的文件：

收到'PARAMS [：房]'在你的控制器，並使用'PARAMS [：房]' – apneadiving

謝謝。所以如果我理解正確。我只是有到控制器更改爲：愛得屋= Room.new（PARAMS [：房]）但後來我得到這樣的錯誤： ::加載ActiveModel ForbiddenAttributesError 我錯過了什麼？ – oliver

看到強大的參數 – apneadiving

在你創建行動：

@room = Room.new(room_params)

，並在您room_params方法，這樣做：params.require(:rooms).permit...
