我有2个表tache
和tarificationtache
one to many
关系。在表tarification
上,我有tache_id
,tarif
和technicien_id
。在表tache
上,我有id
,libelle_tache
和tarif
我希望在页面show.blade.php
上显示来自tarif
的所有tarificationtache tarif
的平均值tache_id = id
来自table tache
。

,这是show.blade.php我想显示每项任务的tarif平均值
tache.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class tache extends Model
{
use SoftDeletes;
protected $guarded = [];
protected $dates = ['deleted_at'];
public function metier()
{
return $this->belongsTo(Metier::class);
}
public function tarificationtache()
{
return $this->hasMany(Tarificationtache::class);
}
}
答案 0 :(得分:0)
您应该在tache
模型上创建方法。
像
public function getAverage() {
//here you would get all the relationships and return the avarage
$total = 0;
foreach ($this->tarificationtache as $tarification) { //if tarificationtache() is the name of your relationship to your other model...
$total =+ $tarification->tarif;
}
//return average by dividing total by number of tarifications
return ($total / (count($this->tarificationtache)));
}
这是一种伪代码,因为我不知道你在模型上所谓的关系,但你明白了吗?
然后在您的观点中,您可以致电
$tache->getAverage()
