Laravel check if updateOrCreate performed update

Question

I have the following code in my controller:

for($i=0; $i<$number_of_tourists; $i++) {  $tourist = Tourist::updateOrCreate(['doc_number' => $request['doc_number'][$i]], $tourist_to_update);  } 

each time "updateOrCreate" works, it does 1 of 3 things:

1) updates model instanse OR

2) creates and saves a new one OR

3) leaves everything unchanged (if model with such values already exists).

I need to check if 'updateOrCreate' has done exactly 1 (updated) and then execute some code.

How can I do it?

Thank you in advance!

Answer 1

You can figure it out like this:

$tourist = Tourist::updateOrCreate([...]);  if(!$tourist->wasRecentlyCreated && $tourist->wasChanged()){     // updateOrCreate performed an update }  if(!$tourist->wasRecentlyCreated && !$tourist->wasChanged()){     // updateOrCreate performed nothing, row did not change }  if($tourist->wasRecentlyCreated){    // updateOrCreate performed create }

Remarks

From Laravel 5.5 upwards you can check if updates have actually taken place with the wasChanged and isDirty method.

• isDirty() is true if model attribute has been changed and not saved.
• wasChanged() is true if model attribute has been changed and saved.

There is also a property (not method!) wasRecentlyCreated to check if user was created or not.

$user = factory(\App\User::class)->create();  $user->wasRecentlyCreated; // true $user->wasChanged(); // false $user->isDirty(); // false  $user = \App\User::find($user->id);  $user->wasRecentlyCreated; // false $user->wasChanged(); // false $user->isDirty(); // false  $user->firstname = 'Max';  $user->wasChanged(); // false $user->isDirty(); // true  $user->save();  $user->wasChanged(); // true $user->isDirty(); // false  //You can also check if a specific attribute was changed: $user->wasChanged('firstname'); $user->isDirty('firstname');
