How to Insert or Update Records Efficiently Using Eloquent\'s firstOrNew() Method?

Inserting or Updating Records in Laravel Eloquent

When working with databases, it's common to need to insert a new record if it doesn't exist or update an existing record if it does. In Laravel's Eloquent ORM, this can be done concisely using the firstOrNew() method.

Syntax

$model = Model::firstOrNew($attributes);

• $attributes: An array of attributes that should be present in the first or newly created record.

Updating Existing Records

If the record already exists in the database, the firstOrNew() method will return an instance of that model. You can then modify its attributes and save it using the save() method.

<code class="php">$user = User::firstOrNew(array('name' => Input::get('name')));
$user->foo = Input::get('foo');
$user->save();</code>

Inserting New Records

If the record doesn't exist in the database, the firstOrNew() method will create a new instance of the model with the specified attributes. It will then insert the record into the database when you call the save() method.

<code class="php">// Insert new record into database</code>

Alternative Approach

In the provided code snippet, the following approach is also used to insert a new record if it doesn't exist or update an existing record if it does:

<code class="php">$shopOwner = ShopMeta::where('shopId', '=', $theID)
    ->where('metadataKey', '=', 2001)->first();

if ($shopOwner == null) {
    // Insert new record into database
} else {
    // Update the existing record
}</code>

This approach involves first querying the database to retrieve the existing record. If no record is found, a new record is inserted. Otherwise, the existing record is updated.
