Call to a member function update() on null

• Update record using find() method with static value in laravel 8

  //routes\web.php
  use App\Http\Controllers\HomeController;
  Route::get('/update-record',[HomeController::class, 'updateRecord']);
  
  //app\Http\Controllers\HomeController.php
  //Import post model in controller
  use App\Models\Post;
  
  //Controller's method to update record with static value
  public function updateRecord(){
      $id = 1;
      $post = Post::find($id)->update(['description'=> 'Lorem ipsum']);
      echo $post;
  }
  

  Output :

  If record exists with specific argument value and update query executed successfully

  1

  If record does not exists and update query not executed successfully

  Error : Call to a member function update() on null

   The error Call to a member function update() on null means that Post::find($id) returned null. This may be because $id is itself null, or the value of $id does not exist in the id column of the posts table. 

  You have to check the $id value should not be null and after that you have to check the record with this id (value) exists in the table. It will return 1 if everything is ok else it will return Call to a member function update() on null.
