Laravel: How to verify if model was changed

Is there a simple way for the Eloquent save method to check if a row has actually changed? Something like affected_rows for Eloquent?

The only workaround that I found was from Laravel Eloquent update just if changes have been made to do:

$user = Auth::user(); $timestamp = $user->updated_at; $user->title = $request->input('title'); .... $user->save(); if($timestamp == $user->updated_at){ // row was not updated. } 

But is this possible to find this out shorter, without the need of a $timestep variable and the check? I don't want to repeat that logic in every controller.

I am looking for something like this:

$user = Auth::user(); $user->title = $request->input('title'); .... if($user->save()){ // row was updated. } 

But this does not work since $user->save returns true in both cases. Is there another way?

First of all instead of:

$user->save 

you should rather use:

$user->save(); 

And to verify if anything was changes in latest Laravel you can use:

if ($user->wasChanged()) { // do something } 

but be aware this is as far as I remember in Laravel 5.5

You could also skip the save altogether and check if your model ->isDirty(), before calling ->save() at all.

// ... $user->title = $request->input('title'); if ($user->isDirty()) { $user->save(); } 

Besides isDirty(), you also have isClean(), and more.

Instead use update() to update the records...

$user = Auth::user(); $userUpdated = $user->update($request->all()); //Print number of updated rows... print($userUpdated); 

This will show you the number of affected rows...
