我有一个关系user->sales->detail_sales
,一个用户有一个或多个销售,一个销售有一个或多个详细信息。我想做的是从 ELOQUENT 获得,每个用户的所有销售额的总和,即用withCount使计算出的总收入达到sum(totaldetails)
。
Sale.php
public function detail()
{
return $this->hasMany(Detail:class);
}
public function user()
{
return $this->belongsTo('App\User');
}
DetailSale
public function sale()
{
return $this->belongsTo(Sale::class);
}
用户
public function sales()
{
return $this->hasMany(Sale::class );
}
我目前有这个查询
return App\User::with(['sales' => function($query){
// get total for detail_sales for sale
$query->withCount(['detail as totaldetails' => function($que){
$que->select(DB::raw('sum(subtotal)'));
}]);
}])->get();
但是我希望在用户模型中拥有例如 salestotal 之类的属性,
@foreach($users as $user)
{{ $user->salestotal}}
@endforeach

您可以将withCount()
与HasManyThrough
关系一起使用:
class User extends Model
{
public function details()
{
return $this->hasManyThrough(Detail:class, Sale::class);
}
}
return App\User::withCount(['details as salestotal' => function($query) {
$query->select(DB::raw('sum(subtotal)'));
}])->get();
@foreach($users as $user)
{{ $user->salestotal }}
@endforeach

为什么不只使用sum()
函数,因为它都在集合中?
@foreach($users as $user)
{{ $user->sales->sum('totaldetails') }}
@endforeach

我希望这会有所帮助:
return App\User::with(['sales' => function($query){
// get total for detail_sales for sale
$query->withCount(['detail as totaldetails' => function($que){
$que->select(DB::raw("SUM(subtotal) as salestotal"));
}]);
}])->get();
