我应该为 laravel 中的每个功能分开 Pivot 表吗？

Question

I'm building review product application where there are 3 database tables - Review - Categories - Affiliates

At first i created a pivot table with 2 entries review_id & category_id & the sync was successfull. Later i added another column "affiliate_id" to the pivot table & the sync was successfull but with multiple entries. Let me explain

Here's my controller for review -

 $result->affiliates()->sync($aff_ids);
 $result->category()->sync($product);

The above code is creating sperate pivot entries -

Pivot Table -

+-----------+-------------+--------------+
| review_Id | category_id | affiliate_Id |
+-----------+-------------+--------------+
|         1 | null        |   1          |
|         1 | 1           | null         |
+-----------+-------------+--------------+

Is the above pivot table correct or should i create seperate pivot tables for affiliates & categories?

If the pivot table is not correct & if there is no need for seperate pivot tables then what i want to achieve is -

+-----------+-------------+--------------+
| review_Id | category_id | affiliate_Id |
+-----------+-------------+--------------+
|         1 |           1 |            1 |
+-----------+-------------+--------------+

The affiliate_id column can have have multiple entries so final result i want is -

+-----------+-------------+--------------+
| review_Id | category_id | affiliate_Id |
+-----------+-------------+--------------+
|         1 |           1 |            1 |
|         1 |           1 |            2 |
|         1 |           1 |            3 |
+-----------+-------------+--------------+

Answer 1

use withPivot;

in Review Model class

public function category()
{
    return $this->belongsToMany(Category::class)->withPivot('affiliate_id');
}

Then

foreach ($categories as $category) {
       $category_id_array[$category->id] = ['affiliate_id' => $affiliate->id];
}

//Insert into offence_photo table
$review->category()->sync($category_id_array, false);//dont delete old entries= false
