Laravel 5.7 - 从当前用户组中获取所有用户

Laravel 5.7 - Get all users from current user groups

这是我目前使用的结构

模范用户:

class User extends Authenticatable implements MustVerifyEmail


public function groups()
{
    return $this->belongsToMany('App\Group')
        ->withTimestamps();
}

模型组:

class Group extends Model

public function users() {
    return $this->belongsToMany('App\User')
        ->withTimestamps();
}

枢轴 table :

    Schema::create('group_user', function (Blueprint $table) {
        $table->integer('group_id');
        $table->integer('user_id');
        $table->integer('role_id')->nullable();
        $table->timestamps();
    });

我想获取与当前用户在同一组中的所有用户,并且不要 return 重复用户(一个用户可以在多个组中)。 理想的功能是:

$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

有一个我正在处理的非功能性函数(模型 User.php):

    public function contacts()
{

    $groups = $this->groups;
    $contacts = new \stdClass();

    foreach ($groups as $key => $group) :

        $contacts->$key = $group->users;

    endforeach;

    return $contacts;

}

我真的不是 table 结构的专家所以如果有更好的方法来做到这一点,我只是在这个个人项目的开始所以没有什么是一成不变的。

可选内容:

您可以在您的用户模型上尝试类似的操作

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();
}
