How can I write a relation for pivot table in Laravel? - php

Question

Here is my table structure:
// tickets
+----+------------+----------------------+--------+---------+-------------------+
| id | subject | content | closed | user_id | unique_product_id |
+----+------------+----------------------+--------+---------+-------------------+
| 1 | subject1 | question1 | 0 | 123 | 2 |
+----+------------+----------------------+--------+---------+-------------------+
// unique_product
+----+---------------+------------+
| id | serial_number | product_id |
+----+---------------+------------+
| 1 | 2342rd34fc | 3 |
| 2 | fg34gt4r5t | 1 |
| 3 | 34ffvv4et6 | 3 |
+----+---------------+------------+
// products
+----+--------------+
| id | name |
+----+--------------+
| 1 | Router-rb51 |
| 2 | Switch-sfx2 |
| 3 | Router-rb300 |
+----+--------------+
Now I have a collection of tickets like this:
$tickets = tickets::where(user_id, "$user_id")->get();
foreach( $tickets as $ticket ){
$ticket->{I need to get the name of product here}
}
I can write a relation in the tickets model like this:
public function unique_product()
{
return $this->hasOne(unique_product::class, 'id', 'unique_product_id');
}
And I need one more relation to the products table for getting the name of product (i.e. Switch-sfx2). How should I write that relation?

Answer 1

$tickets = tickets::where(user_id, "$user_id")->with('unique_product.product')->get();
You can take advantage eager loading using with().
but for using with('unique_product.product') You have to define the relation ships between unique_products and products.
In your UniqueProduct model create a new relationship
public function product()
{
return $this->BelongsTo(Product::class, 'id', 'product_id');
}
After that you can access the column of a name like
foreach( $tickets as $ticket ){
$ticket->unique_product->product->name
}
