我在这里再次请求你的帮助。
我想将分支产品与数量分组，但是，我无法将产品名称显示为产品名称。到现在为止，它显示的是产品id而不是产品名称

+-----------------+   +-----------------+    +----------------+ 
  |  product table  |   | quantity table  |    |  branch table  |
  +-----------------+   +-----------------+    +----------------+
  |   id            |   |  prod_id      |    |   id           |
  |   productname   |   |  branch_id       |    |   branchname   |
  +-----------------+   |  quantity       |    +----------------+
                        +-----------------+

分支模型

public function products()
    {
        return $this->hasMany('App\Quantity', 'branch_id');
    }

数量模型

public function branch()
    {
        return $this->belongsTO('App\Branch', 'branch_id', 'id');
    }

产品型号

public function productquantities()
    {
        return $this->hasMany('App\Quantity','prod_id');
    }

我的观点

@foreach($dataBranch as $Branch)
            <h1>Branch {{$Branch->branch_name}}</h1>
            <table class="table table-striped table-bordered">
                <thead>
                  <tr>
                    <th>  </th>
                    <th>Product Name</th>
                    <th>Quantity</th>
                  </tr>
                </thead>
                <tbody>
                  @forelse($Branch->products as $Product)
                  <tr>
                  <td align="center" style="text-align:center"> <a href="#" class="avatar"><img src="{{ asset('productimg') }}/" width="100px"/> </a> </td>
                    <td> <a class="name">{{$Product->prod_id}} //this should be the product name instead of product id</a></td>
                    <td><em class="productprice">{{$Product->quantity}}</em>  </td>

                   </tr>
                   @empty
                   <tr><td colspan='4'><em>No Data</em></td></tr>
                  @endforelse

                </tbody>
              </table>
            @endforeach

我的控制器

$dataBranch = Branch::with('products')->get();
