Ruby traverses MONGO data

    Next_played_videos = @channel. Videos.active.where (: begin_time.gt = begin_time). ASC (: Begin_time)     | video|        = begin_time         = video.begin_time.to_i + video.duration      = video.end_time           video.save    End

With each operation, the efficiency of the traversal is low, you can use the Mongoid inc method to batch the specified field values to increase or decrease, the document see http://mongoid.org/en/mongoid/docs/persistence.html.

Next_played_videos = @channel. Videos.active.where (: begin_time.gt =[email protected], end_at: [Email Protected])
