Question

我尝试将所有折扣产品放在一个页面中，但它不会返回结果

，而完全相同的查询返回会在主页中生成。

function

public function promotions() {
    $promotions = Discount::with('products')->orderby('id', 'desc')->paginate(12);
    return view('front.promotions', compact('promotions'));
  }

route

Route::get('/promotions', 'frontend\FrontendController@promotions')->name('promotions');

blade

@foreach($promotions as $product)
{{$product->title}} // return nothing!
@endforeach

这是我的$product

的dd

dd code

您需要迭代折扣和产品：

@foreach($promotions as $discount)
    {{ $discount->products->title }}
@endforeach
