计算使用活动存储显示的视频的观看次数

Question

使用 active storage 我将视频存储在课程模型中；

class Lesson
   has_one_attached :video
end

显示此代码；

<div class='feed'>
  <%= render partial: 'lesson', collection: @lessons, cached: true %>
</div>

部分是；

<% cache lesson do %>
    <div class="video_size">
       <video controls class='video_size'>
          <source src=<%= rails_blob_path(lesson.video) %> type='video/mp4' />
       </video>
     </div>
<% end -%>

我想存储每个视频实际播放频率的计数，即按下视频中的播放按钮。我该怎么做？

Answer 1

在我看来，如果你想统计或存储每个视频实际观看的频率，你应该自定义跟踪

ActiveStorage::YourController at 'show' action

像那样：

# In app/controllers/active_storage/base_controller.rb
class ActiveStorage::BaseController < ActionController::Base
  before_action :your_implemnt_method!
  include ActiveStorage::SetCurrent

  protect_from_forgery with: :exception
  def your_implemnt_method!
     ## check what the video you want to increment.
     # and increment number of seen in model via direct for queue it to backgroud worker
     content.plus_seen
     # do something more.

  end
end

到couter_cache或增加观众人数，...等等

另一个解决方案是：你想计算点击播放按钮的次数，只需使用 javascript 处理点击事件，以便将 ajax 请求发送到控制器以增加数数。

JS代码句柄玩法

const player = new Plyr('#player');
$('.plyr__control[data-plyr="play"]').click(function() {
  if (!player.source){

    Rails.ajax({
      type: "POST",
      url: "/url-to-do-sth",
      data: {your_data: data-to-sent},
      success: function(repsonse){
      },
      error: function(repsonse){
        console.log(repsonse);
      }
    })
  }
})

在你的控制器中：

def handle-sth
  begin
    ## Do sothing
    # and increment number of seen in model via direct for queue it to backgroud worker
    content.plus_seen

    render json: {data: data-to-sent}
  rescue
    render :json => { :errors => ["Error with encode or decode."] }, :status => 422
  end
end
