如何使用相关表对结果进行排序?

我有这个表:Clients和Managers(用户表)

Client.php

<?php
class Client extends Eloquent {
    protected $table = 'clients';
    public function Manager(){
        return $this->belongsTo('User','manager','id');
    }
    public function Transaction(){
        return $this->hasMany('ClientTransaction','client','id');
    }
}

Users.php(默认Laravel的模型)

我的问题是如何查询表客户端按Manager的名称排序。

下面是我的代码:

public function getClients() {
    // Sorting preparations
    $allowed    = array('name','contact','money');
    $sort       = in_array(Input::get('sort'), $allowed) ? Input::get('sort') : 'name';
    $order      = Input::get('order') === 'desc' ? 'desc' : 'asc';
    // Get Clients from DB
    if($sort == 'contact'){
        $clients    = Client::with(array('Manager' => function($query) use ($order) {
            $query->orderBy('name', $order);
        }));
    } else {
        $clients    = Client::orderBy($sort, $order)->with('Manager');
    }
    // Filters
    $cname      = null;
    if(Input::has('cname')){
        $clients    = $clients->where('name', Input::get('cname'));
        $cname      = '$cname='.Input::get('cname');
    }
    // Pagination
    $clients    = $clients->paginate(25);
    // Return View
    return View::make('pages.platform.clients')
        ->with('clients', $clients);
}

如果我尝试按名称排序，它会按客户名称排序，但如果我尝试按联系人排序，它需要按用户(经理)名称排序。

试试这个

$clients = Client::join('users as manager', 'manager.id','=','clients.manager')
            ->orderBy('manager.name', $order)
            ->select('clients.*') // avoid fetching anything from joined table
            ->with('Manager');  // if you need managers data anyway

把它放入if语句if($sort == 'contact'){ /***/ }
