The Easiest Way To Pluck Relation Model Attributes In Laravel.

If you ever used the pluck eloquent methods, you can see that, it will get a set of key or key => value columns, if you pass the second parameter

 1$users = User::pluck('name', 'id');
 2 
 3// will return
 4Illuminate\Support\Collection {
 5    all: [
 6        1 => 'Oussama',
 7        2 => 'Nuno',
 8        // ...
 9    ]
10}

But what about relationship columns? Did we need to make something like this

 1$users = User::with('profile')->get();
 2$address = [];
 3 
 4foreach($users as $user) {
 5    $address[] = [
 6        $user->id => $user->profile->pluck('address'),
 7    ];
 8}
 9 
10// will return
11array:2 [
12    1 => 'Some Address',
13    2 => 'Another Address',
14    // ...
15]

I don't think the above code, is a good idea! Instead, we can use:

 1$address = User::with('profile')->pluck('profile.address', 'id');
 2 
 3// will return
 4Illuminate\Support\Collection {
 5    all : [
 6        1 => 'Some Address',
 7        2 => 'Another Address',
 8        // ...
 9    ]
10}
