我有2个表DealerProduct和DealerProductPayments dealer_products包含id和dealer_id列以及dealer_products_payments表,其中包含id和dealer_products_id列
我拥有属于关系的DealerProductPayment模型
public function dealerproduct() {
return $this->belongsToMany('DealerProduct','dealer_product_payments','dealer_product_id','id');
}
我试图从belongsToMany关系中获取dealer_id
$dealerProductPayment = DealerProductPayment::all();
foreach ($dealerProductPayment as $payment) {
echo $payment->dealerproduct->dealer_id;
}
但它不起作用,有人可以帮忙吗?感谢

$payment->dealerproduct
的返回值将是一个集合,因为您声明关系为belongsToMany
。从某种意义上说,一笔付款属于多个产品,因此,当您执行$payment->dealerproduct
时,您将获得一系列产品。
foreach ($dealerProductPayment as $payment) {
foreach ($payment->dealerproduct as $dealerproduct) {
echo $dealerproduct->dealer_id;
}
}
