数据库只保存最后一次迭代，laravel 5.4

Question

请为什么下面的代码只保存最后一次迭代？

foreach($videos as $video) 
    { 
     $filename=$video->getClientOriginalName(); 
     $vidWay=public_path('videos'); 
     $lessons->video=$filename; 
     // echo $filename; 
     $video->move($vidWay,$filename); 
     $lessons->title=$lesson_titles[$upload_count]; 
     $lessons->course_id=$Course->id; 
     $lessons->save(); 
     $upload_count++; 
      // echo $filename; 
    } 

任何想法？

我认为代码必须是这样的

foreach($videos as $video) 
    { 
     $lessons=new App\Lessons() 
     $filename=$video->getClientOriginalName(); 
     $vidWay=public_path('videos'); 
     $lessons->video=$filename; 
     // echo $filename; 
     $video->move($vidWay,$filename); 
     $lessons->title=$lesson_titles[$upload_count]; 
     $lessons->course_id=$Course->id; 
     $lessons->save(); 
     $upload_count++; 
      // echo $filename; 
    }
