rails 命名空间表单不会将数据写入数据库

Question

我是 Rails 新手，想知道为什么我的表单没有将数据写入数据库？ 如果我在控制器中显示数据，例如

render text: params[:post].inspect

它向我展示了正确的细节。如果我将表单发送到数据库，则只显示一个新 id 以及 created_at 和 updated_at 数据。

也许有人可以帮助我...

这是我的文件：

end

end

 class Room < ActiveRecord::Base
 end

表单：（/views/manage/rooms/form.html...）

在您的创建操作中：

@room = Room.new(room_params)

在您的 room_params 方法中，执行：params.require(:rooms).permit...
