  +-----------------+   |  quantity       |    +----------------+
                        +-----------------+

Branch model

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

Quantity Model

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

Product Model

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

My view

@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 

my controller

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

enter code here

Answer 1

As of right now you are joining the branch with the quantities table and NOT the product table. You can do something like below in your Branch model (untested). The idea is a join through Quantity from Branch to Products.

public function productsThroughQuantity() {
    // The columns need to be added
    return $this->hasManyThrough('App\Products', 'App\Quantity', <columns>);
}

However, a problem that I can see, is if you do it this way, you may get an SQL warning about ambiguous columns in regards to branch and product id fields. I would rename in your products table id => product_id and in your branch table id => branch_id. In your quantity table rename branch_id to something like branch_table_id.

Then in your Branch and Product models:

protected $primaryKey = "<branch/products>_id";
