如何保存用户偏好

Question

我有一个应用程序，现在，我需要保存用户的偏好。
我已经做了以下内容：

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 

的问题是：如何才能让一个形式，以节省用户的喜好？我不知道在所有...
什么是赞赏:)

Answer 1

form_for current_user.settings || current_user.build_settings 

还创建控制器

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
