的Rails：試圖更好respond_with語法

Question

我重構了一些舊的代碼理解並想獲得對respond_with語法更好地把握...

這裏是我的控制器：

class VideosController < ApplicationController 
    authorize_resource 
    before_filter :authenticate_user! 

    respond_to :json, :js, :html 

    def index 
    @video = Video.new(athlete_id: current_user.id, sport_id: current_athlete_sport.id) 
    @videos = current_user.videos_for_sport(current_athlete_sport).order("date DESC") 
    respond_with @videos 
    end 

    def create 
    @athlete = Athlete.find(params[:video][:athlete_id]) 
    @video = Video.new(params[:video]) 

    if @athlete.can_add_another_video? && @video.save 
     flash[:notice] = "Successfully created" 
     PandaWorker.perform_async(@video.id) 
     log_activity(@video.logging_information) 
    else 
     flash[:notice] = @video.errors.full_messages.to_sentence 
    end 

    respond_with @video, location: edit_videos_path 
    end 

    def update 
    @video = Video.find(params[:id]) 
    @athlete = Athlete.find(@video.athlete_id) 
    update_featured = params[:video][:featured].eql?("1") && !current_user.featured_video.blank? && current_user.featured_video.id != @video.id 
    current_user.featured_video.update_attribute(:featured, false) if update_featured 

    if @video.update_attributes(params[:video]) 
     flash[:notice] = "Successfully Updated!" 
     log_activity(@video.logging_information) 
    else 
     flash[:notice] = @video.errors.full_messages.to_sentence 
    end 

    respond_with @video, location: edit_videos_path do |format| 
     format.json { render json: { message: flash[:notice], reload: update_featured } } 
    end 
    end 

    def show 
    @video = Video.find(params[:id]) 
    render layout: false 
    end 

    def destroy 
    @video = Video.find(params[:id]) 
    @athlete = Athlete.find(@video.athlete_id) 

    if @video.destroy 
     flash[:notice] = 'Video was successfully destroyed' 
     log_activity(@video.logging_information) 
    else 
     flash[:notice] = 'There was a problem destroying that video' 
    end 

    respond_with @athlete, location: edit_videos_path 
    end 

    def rotate 
    @video = Video.find(params[:id]) 
    @encoding = @video.encode(params[:direction]) 

    if @video.update_attributes(thumbnail_url: @encoding.screenshots.first, mp4_video_url: @encoding.url) 
     flash[:notice] = "Your video was successfully rotated" 
    else 
     flash[:notice] = "There was a problem rotating that video" 
    end 

    respond_with @video, location: edit_videos_path 
    end 

end 

只是好奇要知道我是否以正確的方式做事，在更新/創建方法中更是如此

當控制器可以響應各種格式請求時，這確實只是一種方便。

這是描述它的a pretty good article。
