Laravel 5.7 - Get all users from current user groups - php

Question

This this the structure that I currently use
Model User :
class User extends Authenticatable implements MustVerifyEmail
public function groups()
{
return $this->belongsToMany('App\Group')
->withTimestamps();
}
Model Group :
class Group extends Model
public function users() {
return $this->belongsToMany('App\User')
->withTimestamps();
}
Pivot table :
Schema::create('group_user', function (Blueprint $table) {
$table->integer('group_id');
$table->integer('user_id');
$table->integer('role_id')->nullable();
$table->timestamps();
});
I would like to get all the users who are in same groups of the current user and don't return duplicate users (a user can be in multiple groups).
The ideal functions would be :
$user->contacts()
// Return an object with (unique) contacts of all current user groups
AND
$user->groupContacts($group)
// Witch is the same as $group->users
// Return an object with all the users of the current group
There is the not functional function i'm working on (Model User.php) :
public function contacts()
{
$groups = $this->groups;
$contacts = new \stdClass();
foreach ($groups as $key => $group) :
$contacts->$key = $group->users;
endforeach;
return $contacts;
}
I'm really not an expert with table structures so if there is a better way to do this, i'm only at the beginning of this personnal project so nothing is written in stone.
Optional stuffs :
Exclude current user from the list
With roles from pivot table
With softdelete

You can try something like this on your User model
public function contacts()
{
// Get all groups of current user
$groups = $this->groups()->pluck('group_id', 'group_id');
// Get a collection of all users with the same groups
return $this->getContactsOfGroups($groups);
}
public function groupContacts($group)
{
// Get a collection of the contacts of the same group
return $this->getContactsOfGroups($group);
}
public function getContactsOfGroups($groups)
{
$groups = is_array($groups) ? $groups : [$groups];
// This will return a Collection Of Users that have $groups
return \App\User::whereHas('groups', function($query) use($groups){
$query->whereIn('group_id', $groups);
})->get();
}
