I have a one to many relationship between Device and Command models (each Device has many commands). Now I want to update a collection of commands using save() method. So, I used the following code:
$device = Device::find(1);
$commands = $device->commands()->whereStatus("pending")->get();
$commands->status = "sent";
$commands->save();
但我得到了一个FatalErrorException的异常，错误信息是Call to undefined method Illuminate\Database\Eloquent\Collection::save().
In other words, I am looking for an equivalent MySQL query of the following in the Eloquent:
UPDATE commands SET status = 'sent' WHERE status = 'pending';
