Laravel many to many with column in pivot table - laravel

Question

I have 3 tables:
Worker, payments and private
A private can pay one or more worker and the worker can receive payments from one or more privates.
The payments table contains the 2 foreign key and the amount.
How can I create the relations in the 3 tables with laravel to get all the informations in the db?
For example i want to have for every worker the payments he receives from every private with the amount.

Answer 1

This is how you define many to many relationship between Worker and Private
Worker Model
public function privates()
{
return $this->belongsToMany(Private::class, 'payments', 'worker_id', 'private_id')
->withPivot('amount');
}
Private Model
public function workers()
{
return $this->belongsToMany(Worker::class, 'payments', 'worker_id', 'private_id')
->withPivot('amount');
}
this is how you can retrieve all the privates of a worker
Controller Function
$privates = $worker->privates;
// this '$privates' contains the 'pivot' table values which contains the 'amount'.
this is how you save amount.
Controller Function
// first $private and $worker need to have saved.
// and then attach particular $worker as below.
$private->attach($worker_id, ['amount' => 1200.00]);

Answer 2

I'm assuming you already know laravel relationships.
Worker.php
public function privates()
{
return $this->belongsToMany('App\Private')->withPivot('amount');
}
Private.php
public function workers()
{
return $this->belongsToMany('App\Worker')->withPivot('amount');
}
then in your controller
$private = Private::create();
$worker = Worker::create();
$amount = 1000;
$private->workers()->attach($worker->id, ['amount' => '$amount']);
^^^-column in your payment table.
