如何保存用戶偏好

Question

我有一個應用程序，現在，我需要保存用戶的偏好。
我已經做了以下內容：

class User 
    include Mongoid::Document 
    include Mongoid::Timestamps 

    embeds_one :setting 
end 

和

class Setting 
    include Mongoid::Document 
    include Mongoid::Timestamps 

    belongs_to :user 

    field :notify, type: Boolean 
end 

的問題是：如何才能讓一個形式，以節省用戶的喜好？我不知道在所有...
什麼是讚賞:)

Answer 1

form_for current_user.settings || current_user.build_settings 

還創建控制器

class SettingsController < ApplicationController 
    def create 
    settings = Settings.new params[:settings] 
    if settings.save 
     flash[:notice] = 'Settings saved' 
    else 
     flash[:error] = 'Settings could not be saved' 
    end 
    redirect_to :back 
    end 

    def update 
    settings = Settings.find params[:id] 
    if settings.update_attributes params[:settings] 
     flash[:notice] = 'Settings saved' 
    else 
     flash[:error] = 'Settings could not be saved' 
    end 
    redirect_to :back 
    end 
end
