I'm using Laravel's function firstOrNew()
to create a new user or find and update an existing one.
How can I know, after the object is created, if it existed before or if it's a new object?
The idea is something like this:
$user = \App\User::firstOrNew([ 'email' => $userData->getEmail(), 'name' => $userData->getName(), ]); if ($user->new) { // some way to check // user was created now } else { //user already existed }
It just returns null.
get method give a collection and first method give you a model instance. When you want to get collection of data means, lots of results then use get but if you want to retrieve only one result then use first.
skip() will help to skip some records when you fetch data from the database table. So, let's see bellow examples that will help you how to use take() and skip() eloquent query in laravel.
->latest() fetches the most recent set of data from the Database. In short, it sorts the data fetched, using the 'created_at' column to chronologically order the data.
This function will either return the first record from the database, or instantiate a new model instance that does not yet exist in the database. Therefore, if you'd like to check if the instance was pulled from the database or if it is a new instance, you can check the exists
property (not function) on the model.
if ($user->exists) { // user already exists and was pulled from database. } else { // user created from 'new'; does not exist in database. }
The original question was about firstOrNew()
, but a lot of people seem to come here for firstOrCreate()
, as well. firstOrCreate()
is different, and requires a different check.
This function will either return the first record from the database, or create a new record in the database and return that. Since a newly created record would exist in the database, you can't check the exists
property, because it'll be true in both instances. However, you can check the wasRecentlyCreated
property. This property will be true if the current model instance was just created in the database, or false if it was already in the database.
if ($user->wasRecentlyCreated) { // user just created in the database; it didn't exist before. } else { // user already existed and was pulled from database. }
You can check if your user was recently created.
if ($user->wasRecentlyCreated) { // new user } else { // user already exists }
