Create/Save through relationship

I have the following models:

Below are the relationships:

User belongsTo a group

Group hasMany Users

Device belongsTo group

How can i create a Device through user?

$user = Auth::user();

$new_device = new Device;
$new_device->ip = $request->input('ip');
$new_device->port = $request->input('port');
$new_device->community_name = $request->input('community_name');

$user->group->save($new_device);

Error I am getting when using:

$user->group->save($new_device);

Argument 1 passed to Illuminate\Database\Eloquent\Model::save() must be of the type array, object given, called in /home/snmpexperiments/laravel/app/Http/Controllers/SnmpController.php on line 74

Error I am getting when using:

$user->group()->save($new_device);

Call to undefined method Illuminate\Database\Eloquent\Relations\BelongsTo::save()

I am kind of confused..should i save the device through the group or should i save the device through user?

User Model

public function group()
{
    return $this->belongsTo('App\Group');
}

public function devices()
{
    return $this->hasManyThrough('App\Device', 'App\Group'); // So i can get devices like $user->devices
}

Group Model

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

public function devices()
{
    return $this->hasMany('App\Device');
}

public function interfaces(){
    return $this->hasManyThrough('App\ModelInterface', 'App\Device'); // So I can get interfaces through Device $group->interfaces
}

Device Model

public function interfaces()
{
    return $this->hasMany('App\ModelInterface');
}

public function group()
{
    return $this->belongsTo('App\Group');
}

To save the device through group you would need to specify device.

$user->group->device()->save($new_device);

The way you are doing it your trying to save the group model. The model->save() can accept an array of options that's why you are getting that error.

The correct syntax is $post->comments()->save($comment);. Note the parenthesis after comments, which accesses the relationship method instead of the property. So in this case you would use 

$user->group->devices()->save($new_device);
