Advanced Eloquent

A set of advanced Eloquent macros for Laravel.

⚠️ Note, I've brought much of the functionality provided by this package to Laravel core, in particular the subquery functionality, which has pretty much made this package obsolete. If you want to learn more about these features, be sure to see my Eloquent Peformance Patterns course, which covers these techniques and others in detail.

Installation

You can install this package via Composer:

composer require reinink/advanced-eloquent

This package uses auto-discovery, so there is no further configuration required.

API

`addSubSelect($column, $query)`

$column must be a string.
$query must either be an instance of Illuminate\Database\Query\Builder or Illuminate\Database\Eloquent\Builder.

`orderBySub($query, $direction = 'asc', $nullPosition = null)`

$query must either be an instance of Illuminate\Database\Query\Builder or Illuminate\Database\Eloquent\Builder.
$direction must either be 'asc' or 'desc'.
$nullPosition must either be null, 'first' or 'last'.

`orderBySubAsc($query, $nullPosition = null)`

$query must either be an instance of Illuminate\Database\Query\Builder or Illuminate\Database\Eloquent\Builder.
$nullPosition must either be null, 'first' or 'last'.

`orderBySubDesc($query, $nullPosition = null)`

$query must either be an instance of Illuminate\Database\Query\Builder or Illuminate\Database\Eloquent\Builder.
$nullPosition must either be null, 'first' or 'last'.

Note: Null positions (NULLS FIRST and NULLS LAST) are not supported by all databases (ie. MySQL and SQLite), but are supported by PostgreSQL and others.

Examples

Get a user's last login date using a subquery:

$users = User::addSubSelect('last_login_at', Login::select('created_at')
    ->whereColumn('user_id', 'users.id')
    ->latest()
)->get();

Same example as above, except using the query builder instead:

$users = DB::table('users')->addSubSelect('last_login_at', DB::table('logins')
    ->select('created_at')
    ->whereColumn('user_id', 'users.id')
    ->latest()
)->get()

Order users by their company name using a subquery:

$users = User::orderBySub(Company::select('name')->whereColumn('company_id', 'companies.id'))->get();

Order users by their last login date, with null values last:

$users = User::addSubSelect('last_login_at', Login::select('created_at')
        ->whereColumn('user_id', 'users.id')
        ->latest()
    )->orderBySubDesc(Login::select('created_at')
        ->whereColumn('user_id', 'users.id')
        ->latest(), 'last'
    )->get();
