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

Laravel	Package
10.x	1.8
9.x	1.7
8.x	1.6
7.x	1.5
6.x	1.4
5.8	1.3
5.5–5.7	1.2

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();
