Laravel 5：在控制器中创建新模型

Question

What is the proper way to create new models in Laravel 5 controllers? I don't want to use models classes names directly, but inject them to controller's constructor instead, like this:

public function __construct(User $user) {
    $this->user = $user;
    // ...
}

To operate on the User model, I would normally use controller's property, like this:

$target = $this->user
               ->women()
               ->whereBetween('age', [18, 29])
               ->get();

But how can I create a new model using $this->user? Normally I prefer to use new User; and assign properties to then use $user->save();. But this way it's rather impossible, isn't it? I know there's create() method, which would work in this case, like this:

$girl = $this->user->create([
    'name' => 'Jessica Hottie',
    'age'  => 21
]);

But this way I'm losing possibility to use associate() method etc.

Do I need to use create() anyway, or maybe there's even better way to handle model dependencies?

You can just do

$girl = $this->user->newInstance($attributes); //this doesn't save the model yet
$girl->relation->associate($some_other_model);
$girl->save();
