Laravel - use the Eloquent where method from within View - php

Question

In Laravel 5.4, I have these tables:
sales_orders : id,order_code, customer_id
out_transactions : id, ref_id
ref_id refers to the primary key (i.e. id) of sales_orders.
First I need to get all the rows from sales_orders with a particular customer_id i.e. 10; Then for each row, I need to query the out_transactions table matching its ref_id against the id of sales_orders table.
Inside the show_all method of the controller RequisitionController, I have :
$query_sales_order=SalesOrder::where('customer_id',10);
$requisitions = $query_sales_order->get();
$model=InventoryOutTransaction::query();
return view('admin.requisition.requisition',compact('requisitions')->withModel($model);
Inside the requisition.blade.php, I have :
foreach($requisitions as $aP) {
$requisition_id = $aP->id;
$inventory_out_info = $model->where('ref_id', $requisition_id);
echo '<br/> sql = '.$inventory_out_info->toSql();
$inventory_out_result = $inventory_out_info->get();
$inventory_out_info_id = 0;
foreach ($inventory_out_result as $inventory_out_result_indiv) {
$inventory_out_info_id = $inventory_out_result_indiv->id;
echo ' inventory_out_info_id = '.$inventory_out_info_id;
}
}
But the sql shows unexpected query .
What I get in a case is
sql = select * from `out_transactions` where `ref_id` = ?
sql = select * from `out_transactions` where `ref_id` = ? and `ref_id` = ?
sql = select * from `out_transactions` where `ref_id` = ? and `ref_id` = ? and `ref_id` = ?
So you can see that the where clause is being concatenated. And the concatenated clause remembers the 1st, 2nd etc values of ref_id from the for loop to use each of them, I guess ( I just cannot print the exact value of ? in the query).
How can I just remove the concatenation ? or Any other way to achieve the same purpose ?

Answer 1

First try this query in your controller and print the answer once your expected result is come change your controller with this query and pass the result into view page and foreach the results with your need.
$result = DB::table('sales_orders')->join('out_transactions','sales_orders.id','=','out_transactions.ref_id')->where('sales_orders.customer_id',10)->get();
