php - How to assign a Foreign Key Value in Laravel efficiently -

so started playing laravel last night, i'm coming experience using django framework python.

so there's quite few similarities , i'm quite impressed far.

however, i'm having difficulty understanding how assign foreign key value table.

for example, have 2 models.

user order

order have foreign key value user. order - has foreign key user, titled user_id

what expect able do, coming django, can authenticated user , assign directly foreign key value using this...

$order->user = auth::user();

$order->user_id = auth::user();

however, doesn't work... work if manually user_id so...

$order->user_id = auth::user()->id;

it seems me there should exist ability laravel recognize want id of user object due foreign key definition without me having specify it... in django.

does laravel support this, , if how implemented? i'm using laravel 5.0

i'm guessing have hasmany <-> belongsto relationship between user , orders.

if so, efficient way set actual order user doing follow :

$user->orders()->associate($order);

you have have orders() method in user class :

public function orders() {     return $this->hasmany('path\to\your\models\order'); }
