Laravel Eloquent eager loading with limit

#Eloquent Eager Limit

[!NOTE] The package's code has been merged into Laravel 11+ and eager loading limits will be supported natively.

This Laravel Eloquent extension allows limiting the number of eager loading results per parent using window functions.

Supports Laravel 5.5–10.

#Compatibility

• MySQL 5.7+
• MySQL 5.5~5.6: Due to a bug in MySQL, the package only works with strict mode disabled.
  In your config/database.php file, set 'strict' => false, for the MySQL connection.
• MariaDB 10.2+
• PostgreSQL 9.3+
• SQLite 3.25+: The limit is ignored on older versions of SQLite. This way, your application tests still work.
• SQL Server 2008+

#Installation

composer require staudenmeir/eloquent-eager-limit:"^1.0"

Use this command if you are in PowerShell on Windows (e.g. in VS Code):

composer require staudenmeir/eloquent-eager-limit:"^^^^1.0"

#Versions

#Usage

Use the HasEagerLimit trait in both the parent and the related model and apply limit()/take() to your relationship:

class User extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
 
    public function posts()
    {
        return $this->hasMany('App\Post');
    }
}
 
class Post extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
}
 
$users = User::with(['posts' => function ($query) {
    $query->latest()->limit(10);
}])->get();

Improve the performance of HasOne/HasOneThrough/MorphOne relationships by applying limit(1):

class User extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
 
    public function latestPost()
    {
        return $this->hasOne('App\Post')->latest()->limit(1);
    }
}
 
class Post extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
}
 
$users = User::with('latestPost')->get();

You can also apply offset()/skip() to your relationship:

class User extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
 
    public function posts()
    {
        return $this->hasMany('App\Post');
    }
}
 
class Post extends Model
{
    use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;
}
 
$users = User::with(['posts' => function ($query) {
    $query->latest()->offset(5)->limit(10);
}])->get();
