[英]Laravel Updating Relationship Column in WhereHas
我想用wherehas更新模型中的列。 但是,我不确定如何执行此操作。 这是我的查询下面
$unused = Sale::whereHas('salesdetails',function($query) {
$query->where('product_id', '<=', 24)->where('switch', 1);
})->where(DB::raw("(DATE_FORMAT(transaction_date,'%Y-%m-%d'))"), '<', $now)->update(['switch' => 0]);
销售模式
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Sale extends Model
{
protected $table = 'sales';
protected $primaryKey = 'id';
public $timestamps = false;
public function user()
{
return $this->belongsTo('App\User', 'member_id', 'id');
}
public function guest()
{
return $this->belongsTo('App\Guest', 'guest_id', 'id');
}
public function salesdetails()
{
return $this->hasOne('App\Sales_details','sales_id', 'id');
}
public function discount()
{
return $this->hasOne('App\Discount','id', 'discount_id');
}
}
销售细节模型
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Sales_details extends Model
{
protected $table = 'sales_details';
protected $primaryKey = 'id';
public $timestamps = false;
public function sale()
{
return $this->belongsTo('App\Sale', 'sales_id', 'id');
}
public function product()
{
return $this->belongsTo('App\Product', 'product_id');
}
}
在上面的查询中,我想将所有开关从salesdetails关系更新为“ 0”。 我该怎么办?
您尝试的是错误的,您应该这样尝试
Sale::where(DB::raw("(DATE_FORMAT(transaction_date,'%Y-%m-%d'))"), '<', $now)->salesdetails()->where('product_id', '<=', 24)->where('switch', 1)->update(['switch' => 0]);
我假设transaction_date
列在Sale
模型中。
由于您是在更新SalesDetails而不是Sale,因此我会反转查询,以便更新实际上在SalesDetails而不是Sale上:
Sales_details::whereHas('sale', function($query) use ($now){
$query->where(DB::raw("(DATE_FORMAT(transaction_date,'%Y-%m-%d'))"), '<', $now)
})->where('product_id', '<=', 24)->where('switch', 1)->update(['switch' => 0]);
