[英]Laravel order a relation by method on the model
Trying to think of alternate ways to get what I need from my API. 尝试思考从我的API获取我所需要的替代方法。
I am using Laravel Spark and have a query along the lines of: 我正在使用Laravel Spark并按以下方式进行查询:
$team = Team::with('users')->find($id);
The users relationship on the Team model is: 团队模型上的用户关系为:
public function users()
{
return $this->belongsToMany(
'App\User', 'team_users', 'team_id', 'user_id'
)->withPivot('role')->orderBy('current_active_team', 'DESC');
}
I am currently ordering this by a field on the users table, but I also want to order by a method on the Users model: 我目前正在通过用户表上的字段对此进行排序,但我也想通过用户模型上的方法进行排序:
public function queueLength()
{
// returns an integer for the users queue length
}
To return this data I am currently adding this under my query: 要返回此数据,我目前正在查询中添加此数据:
foreach ($team->users as $user) {
$user->queueLength = $user->queueLength();
}
Is there a way I can order the $team->users by their queueLength? 有什么办法可以按他们的queueLength命令$ team-> users?
One solution will be use collection sortBy
. 一种解决方案是使用collection sortBy
。
First make queueLength as an attribute. 首先将queueLength作为属性。
public function getQueueLengthAttribute()
{
// returns an integer for the users queue length
}
Then use collection sortBy 然后使用集合sortBy
$team->users->sortBy('queueLength');
PS: this will not be a good idea if you have huge amount of data or using pagination. PS:如果您有大量数据或使用分页,这将不是一个好主意。
