Fetch all linked accounts in Laravel 5.4 using Eloquent ORM.

Fetch all linked accounts in Laravel 5.4 using Eloquent ORM.

To fetch all linked accounts in Laravel 5.4 using Eloquent ORM, you would first need to define the relationships between the models involved. Let's assume we have two models: User and Account. A user can have multiple accounts, and each account belongs to a user.

Here's how you can define the relationships in the models:

// app/User.php
class User extends Authenticatable
{
    public function accounts()
    {
        return $this->hasMany(Account::class);
    }
}

// app/Account.php
class Account extends Model
{
    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

Now that we have defined the relationships, we can use Eloquent to fetch all linked accounts for a given user. Here's an example query:

// Fetch all accounts for a user with ID 1
$user = App\User::find(1);
$accounts = $user->accounts;

// Or you can use the with() method to eager load the accounts relation
$user = App\User::with('accounts')->find(1);
$accounts = $user->accounts;

In the first example, we use the hasMany relationship to retrieve all related Account instances for the given User. In the second example, we use the with() method to eager load the accounts relation, which can improve performance if you need to access the related accounts later in the query.

Note that in Laravel 5.4, Eloquent supports multiple relationships with the same name, so you can also define multiple accounts relationships with different names if needed, such as social_accounts or payment_accounts. Just make sure to use the correct relationship name when fetching the related instances.
