數據庫只保存最後一次迭代，laravel 5.4

Question

請爲什麼下面的代碼只保存最後一次迭代？

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？

Answer 1

我認爲代碼必須是這樣的

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; 
    }
