Laravel Model CRUD Operations

### Creating a New Model Record

1. **Using the `create` method**:
The `create` method is useful when you're passing an array of attributes to create a new record in the database. For this to work, the model needs to have `$fillable` or `$guarded` properties defined.

// Example: Creating a new user
use AppModelsUser;

$user = User::create([
    'name' => 'John Doe',
    'email' => 'john@example.com',
    'password' => bcrypt('password123'),
]);

Make sure your model has the `$fillable` property to allow mass assignment:

// In the User model (User.php)
protected $fillable = ['name', 'email', 'password'];

2. **Using the `save` method**:
You can also create a model instance manually and then call `save()` to insert it into the database.

$user = new User();
$user->name = 'John Doe';
$user->email = 'john@example.com';
$user->password = bcrypt('password123');
$user->save();

### Updating an Existing Model Record

1. **Using the `update` method**:
If you want to update an existing record, you can use the `update` method. Similar to `create`, it accepts an array of attributes and updates the corresponding record.

$user = User::find(1); // Find the user with id = 1
$user->update([
    'name' => 'Jane Doe',
    'email' => 'jane@example.com',
]);

2. **Updating specific fields**:
If you don't want to use mass assignment, you can manually set the fields and call `save()`:

$user = User::find(1);
$user->name = 'Jane Doe';
$user->email = 'jane@example.com';
$user->save();

### Upsert (Create or Update)

Laravel also provides an `upsert` method, which inserts a record if it doesn't exist, or updates it if it does.

User::upsert([
    ['email' => 'john@example.com', 'name' => 'John Doe', 'password' => bcrypt('password123')],
], ['email'], ['name', 'password']);

In the example above, if a user with the email `john@example.com` exists, it updates the `name` and `password`. Otherwise, it inserts a new record.

These are the common ways to create or update models in Laravel. Let me know if you need more details on any of these!

$emailsets = Emailset::orderBy('id', 'desc')->get()->map(function ($emailset) {
    // Add a custom 'encrypted_id' column
    $emailset->encrypted_id = Crypt::encrypt($emailset->id);
    return $emailset;
});

### Explanation:
– `orderBy('id', 'desc')`: This orders the results by the `id` column in descending order.
– `get()`: Fetches the results.
– `map`: Iterates over the results to add the `encrypted_id` column using Laravel's `Crypt::encrypt()`.

This will return the `Emailset` models ordered by `id` in descending order and append the `encrypted_id` to each item in the collection.
